The week AO3 was down, fanfic writers posted their new chapters on Ellipsus

What it is A free Google Docs alternative for writers, with collaboration and offline support. It explicitly doesn't use generative AI, and its main users are fanfic writers.

Why it took off The web version built up roughly 800k anti-AI writers, so when the native app launched, the pent-up demand converted. Starting 10-29, AO3 was hacked and down for 2–4 weeks, and writers switched to posting via its public reader links, with readers downloading the app to follow along.

CHow you could follow Don't build a copy of this editor in English. Pick a creator community or language that shares the anti-AI stance but isn't covered by Ellipsus (Chinese fanfic communities, Japanese pixiv circles, etc.). Start with a small slice, either "backup + public reader link" or "proving your work isn't AI," and win users by taking consistent public stances within the community.

C grade: it got here through two or three years of accumulated community trust, 800k long-time users, and the one-off event of AO3 going down, none of which followers can replicate. The editor itself is a commodity and monetizes weakly. The lessons are "not using AI can itself be a positioning" and capturing traffic from a platform outage. Buzz in small circles

Ellipsus is a collaborative writing tool built by a team of 9 people in Berlin. It's free, works offline, and its signature is "never touches generative AI." Its users are mainly fanfic writers. It launched on Android in October and by 11-06 had 62k installs on Google Play. Its rank on the US Productivity free chart climbed from #184 to #62 in a week. This isn't a cold start for a new product: the web version had already built up about 800k writers, and the app was something they had been waiting for a long time. The November acceleration was pushed by the outage of AO3, the world's largest fanfic archive. The playbook is worth studying, but copying it isn't worth the effort.

A Pokémon fanfic that's 130k words long

AO3 (Archive of Our Own) went offline on Oct 29, and the next day it confirmed it had been breached. It expects to be down for 2 to 4 weeks. TechCrunch, The Verge, and the New York Times all covered it. 404 Media asked several writers about it. A writer named Ren said she has two long serials running, one a Pokémon Black/White fanfic already at 130k words, and now has nowhere to post: "I see other writers posting gdocs and Ellipsus reader links, but my drafts aren't presentable enough... I'll probably just pause updates for a while."

Ren didn't use it, but many people did. A "PSA: while AO3 is down, Ellipsus is great for sharing your fic" post appeared on r/archiveofourown. A Tumblr writer swapped all her work links to Ellipsus. Ellipsus moved fast: 11-02 it shipped an iOS version, with the caption "We can't bring AO3 back, but here's something else you've been waiting for." 11-03 it pushed a "Kudos theme" mimicking AO3's kudos style, with the line "We've got AO3 at home."

For readers to read or leave comments, they had to click the link, download the app, and log in. This was the first time Ellipsus captured traffic on the "reader" side.

What it is

A Google Docs alternative for writers: unlimited documents and collaborators, real-time collaboration, comments, permission management, and offline writing. The store listing says "no generative AI, no creepy tracking."

What kept fanfic writers around were several features built specifically for them: one-click export into a format AO3 accepts directly (2024-10), fanfic templates, a public reader link called Reader with comments and likes (2026-02), and a writing-process recorder called Emboss that lets you prove "this wasn't written by AI."

Paid is optional via Plus: a one-time $99 purchase, or $6/month for 24 months, or $60/year for two years. Once paid off, you own it permanently. This pricing was set by 3,000 users voting (ellipsus.com/plus). Revenue is not public.

US Productivity free chart 11-03 #184, 11-04 #77, 11-05 #62. Canada, UK, and Australia also reached the top 100 (Google Play charts, 11-03 to 11-06). The iOS version launched 11-02, and in 4 days it collected 118 ratings in the US store.

First, understand this: the 23k on 10-17 wasn't someone "discovering" it. It was pent-up demand converting. In June of 2026 year it described itself as "nearly 600k writers and 5M documents," and an autumn LinkedIn post said "nearly 800k users." The official Android launch post opened with "You waited; you yearned..." On r/AO3, someone said they opened Gmail that day and saw the app-launch email.

Why users switched

Collaborative editors have long been commodities, and Google Docs is free and good. Writers switched because of distrust:

  • AI. Google Docs added Gemini and Word added Copilot, and writers worried their work would be used for training. Ellipsus put "no AI, no training on your work, no censorship" on its homepage.
  • Account lockouts. In July of 2025 year, a group of writers who wrote adult-oriented fanfic found their Google Docs locked, and Tumblr and r/FanFiction discussed it for a while. Ellipsus issued a warning on Tumblr at the time.
  • A public stance. In September of 2024 year, NaNoWriMo (the organizer of National Novel Writing Month in November) publicly backed AI. Ellipsus pulled its sponsorship, and the episode is still recorded in the Wikipedia entry for NaNoWriMo.

Users came, half because the tool was good and half because "using it was taking a stand." This is its moat, and also the hardest part for followers to copy: this kind of trust was built up over two or three years, one event at a time.

There are also critical voices: on r/WritingWithAI someone said it's "riding the anti-AI wave"; the indie publisher Duck Prints Press criticized Emboss for recording every keystroke as surveillance and unfriendly to disabled writers; on TikTok some users complained about sync problems.

Where users come from

  1. Migration from long-time web users, the main driver.
  2. Its own content accounts. TikTok @ellipsus_writes has 16.7k followers and 200 videos, and its Android launch video got 107k views. On Tumblr it regularly posts censorship observations and anti-AI essays, aligned with the fanfic community's mood.
  3. Creators and organic word-of-mouth. There are sponsored #EllipsusPartner videos on TikTok (one, "Have you tried the Android version?" with 10-30 views 7,614), and the organic ones are bigger: a BookTok recommendation with 10-23 got 589k views.
  4. The AO3 outage, the direct cause of this November wave.
  5. NaNoWriMo's November writing month. NaNoWriMo shut down in 2025, but the habit of writing a novel in November remains, and in late October it added a writing-goal feature to Plus.

I found no evidence of paid ad acquisition, but that doesn't mean none was done.

WattpadPlay 346M installsA publishing and reading platform rather than a writing tool; its reputation in fanfic circles is poor (when AO3 went down and it posted "we're here," the replies were almost all telling it to go away)

Novlr / Dabble / Reedsy StudioA niche subscription appAimed at writers of long works, weak on collaboration

ddocs.new(Fileverse)Not verifiedAn encrypted document app that wrote a "Google Docs alternative for fanfic writers" in 2026 year, with selling points nearly copied from Ellipsus's list

As far as I can find, it's the only one that is free, unlimited in collaboration, explicitly avoids AI, and is specifically polished for the fanfic workflow. I found no App copycats.

How well known it is

It's well known among writers: Tumblr, TikTok, r/AO3, r/FanFiction, and XDA (2025-09 wrote "still in beta and already replaced my Google Docs") have all mentioned it, and it got passing mentions in coverage of AO3's outage. It has publicly disclosed its user count and a seed round of $2025M in January of 2 year (led by Speedinvest). But in indie developer and startup circles, almost nobody discusses it, and no major tech accounts on X have written about it.

If it were you

In one line: this business runs on trust a community built over two or three years, plus someone else's outage. Copying it as an English version has no real chance. What you can take away is the playbook.

Who it suits: people already active in a creator community (fanfic, illustrators, translators, web novel writers), with a name in that circle and the ability to speak up consistently.

Who it doesn't suit: developers hoping to win on features. Collaborative editors and offline sync are hard to get right, and even if you do, you end up with just another editor. Ellipsus users didn't switch because of features.

How to do it:

  • Pick a circle or language that also has strong hostility toward AI but isn't covered by Ellipsus. For example, Chinese fanfic circles (Lofter's AI feature was pulled after backlash in 2023), Japanese pixiv circles, or Korean communities, which currently mostly use general-purpose documents or the platform's built-in editor (inference, I haven't verified each community's specific tools).
  • You don't have to build a whole editor. Take the small slice Ellipsus has shown people want: offer "backup + public reader links" to a platform's writers, so you can catch traffic whenever that platform has an incident. Or build "writing-process proof" tools that prove a work isn't AI.
  • Values have to be built through action: public stances, letting users vote on pricing, and a one-time-purchase model.

How to acquire users: post consistently about what insiders care about (censorship, AI training, account lockouts) on Tumblr, TikTok, Xiaohongshu, and Discord within the community, rather than posting product features. On the days a platform has an outage or controversy, have a one-line opportunistic message ready.

When to get in before: there's no clear window. AO3 is expected to recover in mid-to-late November, and this wave of reader traffic will recede. But anti-AI sentiment won't disappear in the short term.

What would show you misread it: once AO3 recovers, if Ellipsus's daily Play installs fall back to a few hundred and its chart rank drops out of the top 200, the wave was just the event. Or if Google Docs or Word announce a clear commitment to "turn off all AI and never use data for training," and writers buy it, this positioning stops being scarce.

A post on r/AO3 says the user got a notification about the app launch in Gmail.
  • Confirmed Platform event: AO3 taken down by hackers: AO3 went offline from 2026-10-29 for 2–4 weeks (TechCrunch, Verge, NYT). Authors switched to posting through Ellipsus Reader links (404 Media 10-30, the r/archiveofourown PSA, Tumblr). 11-02 rode the moment with its iOS launch ("We can't bring AO3 back online…").

Why Ellipsus (com.ellipsus.app) took off

In one line: Ellipsus is an "anti-AI Google Docs" for writers. It's free, collaborative, works offline, and was built by a Berlin team backed by Speedinvest. The Play install numbers don't reflect a new product cold-starting. They reflect a writing tool that already had about 800k web users, moving those users onto a native app. The November acceleration was pushed by a platform event: AO3 (the world's largest fanfic archive) went down for 2–4 weeks after a hack.

Proton Docs / CryptPadWeb2024 / 2017SmallLeads with privacy and encryption, aimed at general office use. No writer community and no AO3 export.

Bottom line: plenty of writing tools exist, but few combine free, unlimited collaboration, a firm no-AI pledge, and features built for fanfic writers (one-click export to AO3, reader links, fanfic templates). This one is nearly alone in doing all of it.

3. Where users come from

  1. Web users who built up over time moving to the app (the main driver). At Plus launch, 2026-06 described itself as "nearly 600k writers, 5M documents, 28k people on Discord" (ellipsus.com/blog/introducing-ellipsus-plus). A LinkedIn post from about October said "close to 800k users, and the app is set for Oct 6." The app was the most-requested feature in its community (the official launch post opens with "You waited; you yearned…"). 10-17 gained about +23k installs in a single day (AppstoreSpy estimate), most likely from an email or in-site notification to the existing user base. A post on r/AO3 says "I opened Gmail today and saw Ellipsus is rolling out an app" (reddit 1x689ix, body blocked by 403, date unverified).
  2. Owned content accounts: TikTok / Tumblr / X / Threads / Bluesky. TikTok @ellipsus_writes has 16.7k followers, 310k likes, and 200 videos (TikHub). Its Android launch video got 107k views, and its "Scribble font" video got 63k views. The Android launch post on X got 320k impressions. On Tumblr, @ellipsus-writes has long posted about moderation watch (KOSA), anti-AI pieces, and Google Docs lockout warnings, siding with the mood of the Tumblr fanfic community.
  3. Paid creator partnerships. TikTok has the #EllipsusPartner tag (e.g. @dicklessthewonderclown 10-30 "Have you tried the Android version yet" 7,614 views), and Instagram has posts under #ellipsuspartner. Plus plenty of organic shoutouts: @scorpiaokbooks 6 10-23 BookTok videos at 589K views; @genevievesreign 21K views.
  4. Platform event: AO3 outage (the direct cause of the November acceleration). AO3 went down on 2026-10-29. 10-30 confirmed a security breach and expected a 2–4 week outage (TechCrunch, The Verge, NYT, Qz, PC Gamer, and Vice all covered it). With AO3 gone, authors started posting new chapters and reposting older work through Ellipsus Reader public reading links (404 Media 10-30 quoted an author: "seeing other authors post gdocs and Ellipsus reading links"; a post on r/archiveofourown, "PSA: Ellipsus is great for sharing your fic while AO3 is down"; Tumblr author the-wine-dark-sea switched all her works to Ellipsus links). Ellipsus capitalized immediately: 11-02 it launched on iOS with the line "We can't bring AO3 back, but we can give you something you've been waiting for" (TikTok, 19k views). 11-03 it posted a "Kudos theme + Reader link, We've got AO3 at home". Readers had to download and log in to read, which gave it its first traffic on the reader side.
  5. November writing month. After NaNoWriMo shut down in 2025, the November writing challenge lived on (Ellipsus calls it "the annual November writing ritual formerly known by a name we do not speak"), and in late October it added Writing Goals to Plus. 2024-09 it withdrew sponsorship over NaNoWriMo's stance supporting AI. That episode is still recorded on Wikipedia's NaNoWriMo page and is one of the starting points of its anti-AI identity.
  6. Media / SEO: XDA 2025-09 wrote "still in beta, it has already replaced my Google Docs." Medium, YouTube, Reddit r/AO3, and r/FanFiction threads about Google Docs alternatives often recommend it. This is a long-running organic search source.

No paid ad evidence found (the ad library doesn't cover it, which doesn't mean it wasn't advertised).

4. Why it took off

  • Riding an identity sentiment: the fanfic and original-writing communities are strongly hostile to generative AI. Ellipsus makes "no AI, no training on your work, no moderation" its core pitch (ellipsus.com/generative-ai), and it has capitalized on NaNoWriMo's sponsorship withdrawal (2024), Google Docs lockouts (2025-07), KOSA, and AI training controversies each time. Users come not just because the tool is good, but because "using it is taking a stance."
  • Features built specifically for fanfic writers: one-click export to AO3 (2024-10), fanfic templates, Reader links with comments and kudos (2026-02), and Emboss writing-process proof (to show the work isn't AI-generated). When AO3 went down, Reader links instantly became a temporary publishing platform.
  • Generous free tier: documents and collaborators are unlimited, and Plus is optional (pay $99 once for a lifetime license, or $6/month × 24 months, or $60/year × 2; once paid, it's yours forever). The pricing came from a survey of 3,000 people, which built community trust (ellipsus.com/plus).
  • The app was the biggest unmet need: the web version and PWA had been around for two or three years, and a native app with offline support was the most-requested feature. So when Android launched, the pent-up demand came in a wave, most likely from existing users rather than newly acquired ones.
  • Timing: Android (10-13), iOS (11-02), the AO3 outage (starting 10-29), and November writing month almost all collided. The iOS launch went out right as AO3 was down.

5. What's the differentiation, and is it why it broke out?

Differentiation = values + use case stacked in two layers:

  • Values: an explicit stance against generative AI, no moderation, privacy first. It positions itself as "a principled alternative to Google Docs."
  • Use case: built around the fanfic writing workflow (collaborating with beta readers and editors → export to AO3 → share a Reader link for readers).

That's why it took off. Taken on features alone, collaborative editors are already a commodity, and Google Docs is free and good; users switched because they don't trust Google or AI, and Ellipsus happens to offer fanfic-specific features Google Docs lacks. But the Play curve itself mostly comes from old web users migrating, plus the AO3 outage, not from anything special about the Android version. There's also pushback: a user on r/WritingWithAI accused it of "riding the anti-AI wave"; Duck Prints Press criticized Emboss for logging keystrokes as surveillance, unfriendly to disabled writers; and some users reported sync problems (TikTok @issa.writes).

6. How many people have seen it

  • Revenue isn't public (no TrustMRR listing or founder revenue posts found). What's public is user count (nearing 600k → close to 800k) and funding (vcbacked: 2025-01 seed round, 2M USD total; Speedinvest portfolio page).
  • Well known in writing communities: Tumblr, TikTok, Reddit r/AO3 / r/FanFiction, the Wikipedia NaNoWriMo entry, and XDA have all mentioned it; it was also name-checked in coverage of the AO3 outage (404 Media). But almost nobody in indie-dev or startup circles discusses it, and no big X accounts have posted about it (searching the local x-radar corpus for "ellipsus" over the past 90 days returns 0 posts).
  • Verdict: it's circulating in a small circle, though a very large small circle (fanfic writers).

7. Copycats

No obvious copycat app found yet. The closest is Fileverse's ddocs.new, which published a post in 2026 titled "A Google Docs alternative for fanfiction writers" (blog.fileverse.io); its selling points (AO3-compatible HTML export, no AI pop-ups) nearly mirror Ellipsus's list. Inkitt also published an "AO3 alternative" article to pull readers during the AO3 outage.

8. What others can learn

  1. In a category where AI is everywhere, explicitly refusing AI can itself be the positioning, provided the target audience (fanfic writers, illustrators, translators, etc.) has strong hostility toward AI as part of their identity.
  2. Values have to be proven through sustained action: pulling sponsorships, publishing audits of censorship, pricing via surveys, subscribe-to-own. All of these build trust that can be cashed in when a crisis hits.
  3. Ride the outages of community platforms: when AO3 went down, its publishing feature (Reader links) happened to catch the demand, and the iOS version launched right on time. Build bridges to big platforms early (export, reader pages) so that when a platform fails, you can catch the overflow traffic.
  4. Start with web / PWA, grow to a few hundred thousand users, then ship a native app to cash in the demand in its first week and push for category charts.

9. Still unclear

  • Was 10-17's single-day gain of roughly +23k installs from a mass email or Play recommendations? (AppstoreSpy's estimate; single-day figures aren't precise.)
  • How much reader traffic will stick once AO3 comes back (expected mid-to-late November).
  • Plus conversion and revenue are completely unknown; whether they run paid ads is unknown too.
  • How many of the 800k users are active is unknown.
