A post with 1.13M views: the OpenCode team retold an old dictation tool as "how to talk to an Agent"

Hold a key, speak, release, and the text gets pasted into whatever app you're using. There are at least dozens of these on GitHub. Hex is one of them. Oct 31 posted a Rust rewrite 3.0, and it gained over 4300 stars in a week. It grew fast mainly because the company behind OpenCode was behind it, and DHH integrated it on launch day. The code itself isn't the main reason. Below: what it is, where the stars came from, how crowded this space is, and which parts of a project that gets stars you can copy and which you can't.

Oct 31 posts (three)

On Oct 31 UTC 02:21, HumanLayer founder Dex Horthy posted on X: "god damn @kitlangton's hex is so good", 25K views. Kit Langton is the author of Hex, and at that point 3.0 was still a few hours away from its stable release.

That day 15:39, OpenCode's official account (230k followers) posted the stable release:

no matter what agent you're using, your voice is the best way to talk to them and hex is the best way to use your voice: fast, runs locally, works on mac, windows, linux

By 11-06 this post had 9155 likes and 1.13M views (X, 11-06).

Six hours later, DHH posted "Made Hex available as a dictation option on Omarchy Dev", with a PR merged that day. Omarchy is his Linux desktop config with 46k stars, and Hex became its third dictation option, behind Superwhisper and Voxtype. This post got 107k views.

Here's how stars moved (GitHub daily snapshots):

11-02 It hit #11,11-04 on GitHub's overall daily trending chart, #10 on Rust's daily chart, and stayed on the Rust chart for several days. From 11-04 it dropped back to a few hundred a day.

What it actually is

A dictation program installed on your computer. Hold a hotkey (Option by default on Mac), speak, release, and it converts the speech to text locally and pastes it where your cursor is. The first run downloads a speech model, after which nothing leaves your computer. Free, MIT-licensed, no sign-up.

It isn't new. Kit Langton built the Mac version of Hex in Swift back in January 2025, gathered 2898 stars, and was repeatedly recommended on Hacker News this year. In February someone wrote on HN: "I haven't seen anything faster than Hex for speech-to-text on Mac... This is now my standard way of talking to coding agents. I used Handy before, Hex is faster."

3.0 is a from-scratch Rust rewrite under the anomalyco organization (the company behind OpenCode, Anomaly, formerly the SST team; opencode under the org has 225k stars). This version changed three things:

• Three platforms on the same day. Mac, Windows x64 and ARM, and Linux with deb, rpm, AUR and Nix packages. Before, it was Mac only, which was its biggest weakness.
• Lighter. Memory dropped from about 900MB to about 160MB (per the release notes).
• Leaning into agents. Pipe what you say through OpenCode to rewrite it before pasting. There's a hex mcp so the agent can call it directly. Experimental Annotate lets you record your screen and voice and send it straight into an OpenCode session. The model catalog lists each model's word error rate, and you can add a vocabulary list for proper nouns.

The README's last section is a talking point too: "We don't take PRs. Open an issue describing the bug or idea, and our agent will usually ship the fix quickly." Four days after launch it went from 3.0 to 3.3, across 5 releases.

The old Swift library has been archived, its stars stuck at 2898 and not carried over. The new repo started from zero.

Where the stars came from

The company's own account. The 1.13M-view OpenCode post lines up with the 11-01-to-11-03 daily gain of 700 to 1,200 stars. It was the biggest source of this wave.

DHH's distro. Once it landed in Omarchy, Linux users had another reason to install it. DHH's own post also pulled six-figure views.

圈内人自来水。 除了 Dex Horthy,OpenCode 的 Dax(17 万粉)11-06 发了一句「always be voice prompting」;有人专门夸它的落地页做得好,9.4 万浏览。落地页首屏只有一句「Speak. It appears.」

Old users and word of mouth. The Swift version was already "the fastest local dictation on Mac" on HN. How many people migrated is unknown, but the reputation was ready-made.

Trending amplification. After hitting the overall daily chart, it drew a second crowd browsing the charts.

What didn't work was Hacker News: three submissions, 10-29, 10-31 and 11-04, the top one reaching 5 points. No paid promotion was found.

How crowded this niche is

The field is crowded. Just the open-source options (GitHub, around 11-06):

Commercial options include Wispr Flow (about $15/month, cloud), Superwhisper (the leading paid Mac option), Aqua Voice, and MacWhisper. Built-in ones include macOS Dictation and Windows Win+H.

More telling are the small libraries that appeared from 9 to October: betterwispr 508, Typeleast 115, Arion 131, voltip 87, sayso 48, lipwise 28. Their pitch is almost always the same line: "hold a shortcut, speak, text appears." They predate Hex 3.0, so they weren't copying it. The category was already being built in bulk. Building it is easy; getting noticed is the hard part.

Hex isn't the first, nor the biggest. The feature gap with Handy is hard for ordinary users to notice. Some on HN say it's faster than Handy and doesn't lag, which can keep users around, but that doesn't explain three thousand stars in three days.

What you can copy and what you can't

What you can't copy is distribution. A 1.13M-view official post, plus DHH plugging it into his distro the same day: ordinary developers can't get those. The same code posted by an unknown author would most likely end up as one of those small libraries with dozens to hundreds of stars (inference).

Three things you can copy:

• Selling an old category to new users. Dictation has been around for decades, but OpenCode isn't pitching "more accurate dictation." It pitches "the best way to talk to any agent." The people writing long prompts every day for 2026 are sick of typing, and this line hits that exactly.
• Launch on one day. Put the stable release, the official post and the celebrity adoption on the same day, then let Trending catch the second wave.
• Use cross-platform support to cover competitors' weak spot. Many rivals in this space are Mac-only. Hex covered Windows and Linux at once, and on Linux it went through distros, AUR and Nix.

If it were you

C: You can learn from it, but following it isn't worth it. The local dictation slot already has Handy, a project with nearly 40k stars, plus Hex and a batch of similar small libraries. Hex's stars mostly came from distribution you don't have access to. Building another push-to-talk dictation tool would struggle to earn stars.

Who it fits: someone who already has a developer audience, such as a maintainer of an agent tool with thousands of stars, or an account with many developer readers, who wants a side tool to funnel traffic to the main project and boost stickiness. For OpenCode, Hex plays exactly that role.

Who it doesn't fit: anyone with no distribution channel who wants to clone a cross-platform dictation tool as-is. You'll become one of those libraries with single- to triple-digit stars. Rewriting it in another language won't help either, since Handy and Hex already both do native Rust across three platforms.

How to do it: don't build dictation itself. Take the small piece Hex handles poorly, or borrow its pitch for a different tool. For example: ① Chinese-English mixed speech for "talking to an agent," specifically handling code terms, command names and library names. The model catalog already has SenseVoice and Qwen3-ASR, but nobody seems to have tuned them for Chinese developers (inference). ② A voice input plugin or MCP for command-line agents like Claude Code or Codex, not a standalone app, plugging straight into tools people already use. ③ Repitch other old tools (screenshot annotation, clipboard, notes) as "for agents."

How to get users: plug into places where the audience already is. Submit PRs to big projects' plugin lists, distros (Omarchy, various dotfiles) and awesome lists. On X, find people in the agent crowd to try it and say "it works." HN doesn't care about this category; Hex's three submissions didn't take off, so don't stake your launch on it.

When to move: the "voice prompting" trend is blowing right now, and every agent vendor could add voice input on its own at any time. The window is measured in months. If you're going to do it, ship a first version before the end of this year.

Signs you've misread it: ① A month from now Hex is still gaining hundreds of stars a day while OpenCode has stopped pushing it, which would mean the product alone draws stars and this piece overrated distribution. ② An unknown author ships a similar dictation library and gets several thousand stars in a month, which would mean the category isn't saturated. ③ OpenCode or Claude Code adds built-in voice themselves, which closes the agent voice plugin route.
