Browser extensions that feed off gaps in AI chat platforms (adding folders, search, and export to ChatGPT / Claude / Gemini / Grok): one-time purchase plus SEO, sold within 12 months
Watching Inspiration · a playbook proven elsewhere that can be transplanted First seen 2026-11-01 · last updated 2026-11-02
- Status
- Watching (only AI Toolbox has revenue in this category, and it's flat; the big four platforms are already crowded, while Perplexity / Kimi / Doubao are still empty. Upgrade only when a second similar product shows 30-day revenue above $3k)
- Why now, and how long the window lasts
- Neither of the four major AI chat products has shipped folders or full-text search in two years, people use several assistants at once, and the gap keeps widening; AI coding lowers the bar for writing extensions. The window is measured as "before native features replace it", and the author's own answer is to list at the peak in about 12 months.
- Confidence
- Low. The only sample with payment-platform revenue is AI Toolbox, and its author is selling it. What would overturn this: if AI Toolbox's November revenue drops more than 20% from October or the listing price is cut → close; if an indie product in Perplexity / Kimi / Doubao shows 30-day revenue above $3k → upgrade to open.

For-sale listings1 evidence items
- For sale (Acquire ymn189qc4d, 11-02): "AI chat management Chrome extension, 40K+ installs, 1,700+ paid", four platforms, about 47k MAU, 93% net margin, 26 months, small team, asking $920,000. The listing card shows TTM revenue of $205,300 and profit of $184,000, annualized from 6–August average monthly $17.1k, not verified receipts. The description, install count, MAU, margin, and asking price all match AI Toolbox, so it's inferred to be the same product; on TrustMRR it shows $121,716 actual revenue over 12 months.
Chrome Web Store 2 pieces of evidence
- Chrome Web Store (11-02): AI Toolbox main extension has 40,000 users and 1,036 ratings, updated 10-29; the same developer's Claude Toolbox 6,000 and older Gemini version 3,000 are being merged into the main extension. This category is already crowded: ChatGPT Exporter 200,000, AI Exporter (saveai.net) 100,000, AI Chat Exporter (Claude version) 100,000, Superpower for ChatGPT 100,000, ChatGPT Bulk Delete 70,000, Gemini Bulk Delete 40,000 (browserlab.io, which also has Gemini / Grok / DeepSeek Toolbox versions), Gemini Chat Folders 20,000, AIPRM 1,000,000.
- Chrome Web Store (11-02, open slots): the largest Perplexity chat management and export extension is Search for Perplexity 10,000; exporters all sit at 500–2,000; Kimi has only one sidebar with 3,000 users; Doubao is not findable; the two DeepSeek exporters have 10,000 each.
Product Hunt1 pieces of evidence
- PH (three launches, 2024-10-21, 2025-06-30, 2026-09-06; 13 / 51 / 425 votes): reached #1 of the day only on the third launch, revenue is a step change rather than a spike; the founder says 100% of traffic comes from Google and AI answer engines, and HN has only one Show HN with 2 points (ph-dossiers/ai-toolbox.md).
Already doing it
AI Toolbox (four platforms, for sale); Superpower for AI; browserlab.io, which built Gemini / Grok / DeepSeek versions; a dozen-plus single-feature exporter and bulk-delete / folder extensions with tens of thousands of users each.
In our product dossiers: AI Toolbox (formerly ChatGPT Toolbox)
The hardest step
Both lifelines are out of the builder's hands: Chrome Web Store review and Manifest policy, and host-platform front-end redesigns. Next is that SEO comparison pages take months to work.
Who it's for
Solo devs who can build browser extensions and keep churning out SEO content, 1–2 people. $99–199 one-time purchase; accept "build it for 12 months, then sell it." Newcomers should look at Perplexity, Kimi, Doubao, and DeepSeek, or turn cross-assistant search exports into a local app or MCP server to reduce the risk of being wiped out by a redesign.
Should every product builder know this?
No.
Change log
2026-11-02
Backfill check: AI Toolbox 30-day $22,645 → $22,653, flat; TrustMRR asking price $800k → $920k. The ymn189qc4d in the sale listing matches, so it's inferred the same product is listed in two places. The TTM $205k on the Acquire card is annualized; verified revenue over 12 months is $121,716. Chrome Web Store user counts for comparable tools check out; Perplexity / Kimi / Doubao are indeed empty.
