One-click prompt improver inside ChatGPT, Claude and Gemini
teleprompt adds an Improve button next to the prompt box on ChatGPT, Claude, Gemini, Lovable and Base44. One click rewrites a rough prompt in place — no copy-paste, no tab switching. A second mode, Craft, builds a prompt from a few guided questions. Live for two years. 7,000 users across 128 countries, Google's Featured badge, 4.6 stars from 76 ratings, Manifest V3 compliant. THE NUMBERS $4,276 trailing revenue against about $10/month in running costs — roughly $4,155 of annual profit at a 97% margin. $212 MRR from 52 active subscribers, out of 258 sold lifetime. 6% monthly churn. Every install is organic Chrome Web Store search; there has never been any paid acquisition. WHY IT IS PRICED AT $12,000 I am selling this honestly, so here is the part most listings leave out. Usage halved this year and MRR is down 26%. The cause is that the extension finds the prompt box by DOM selector, and those break whenever OpenAI, Anthropic or Google change their markup. Across the last year 43% of Improve clicks returned nothing. There is no failure telemetry, which is why Claude stayed fully broken for twelve months before anyone noticed. WHY THAT IS THE OPPORTUNITY On 22 July 2026 I shipped one release that repaired Claude and restored Gemini. No marketing, no new features, no price change. Active users rose 66% within three weeks and were still 50% above baseline five weeks later. Three integrations are still broken — the same lever, sitting unused. Reach is intact and conversion is normal at 2.6%. What the product loses are the users who click once, get nothing back, and never return. WHAT IS INCLUDED Chrome Web Store item with 7,000 users, transferred through Google's official process — extension ID unchanged, existing users undisturbed. The 4.6-star rating and all 76 reviews travel with the item. Google Featured badge. Full source for extension and backend. The prompt-engineering IP, which is the actual product. get-teleprompt.com domain and marketing site. Two years of Mixpanel history. 52 active subscriptions. 30 days of post-sale support. UNCLAIMED UPSIDE Not listed on Edge or Firefox, from the same codebase. Priced at $4.99/month against a $9-13 category norm. No regional pricing, on a user base that is 23% India. No language handling at all, though roughly half of all prompts are not in English. Happy to share full Mixpanel, Google Analytics and Lemon Squeezy data with anyone serious, and to walk through the codebase on a call.
Next step: <p>Repair first. On 22 July 2026, one release that fixed Claude and restored Gemini lifted active users 66% in three weeks, and the gain held at +50% five weeks later — no marketing, no new features, no price change. Three integrations are still broken: ChatGPT at roughly 40% failure on two-thirds of all volume, Gemini at 60%, Claude at about 46%. That is scoped work with an already-measured return.</p><p>Then ship failure telemetry and an alert when any host crosses 20% failures for a day. Everything that broke this year was found late or not at all.</p><p>After that: raise the price from $4.99 toward the $9-13 category norm; add regional pricing, since 23% of users are in India on a flat price; ship Edge and Firefox from the same codebase, neither of which exists today; add language handling, because half of all prompts are not in English; and serve image and video prompting, a large segment in the data that is entirely unserved.</p><p>Discovery is worth attention too. One YouTube video in August 2025 drove more store-listing traffic than the following eleven months combined, and nobody has tried to repeat it.</p>

The main asset is the Chrome Web Store item itself, with 7,000 users. It transfers through Google's official process, so the extension ID does not change and existing users are not disturbed. The 4.6-star rating and all 76 reviews travel with the item, as does the Google Featured badge. Also included: the prompt-engineering IP, which is genuinely the product; the get-teleprompt.com domain and marketing site; two years of Mixpanel history; the Google Analytics property for the store listing; and 30 days of post-sale support. The 52 active subscriptions run through Lemon Squeezy as merchant of record, so transfer terms for those are worth confirming with Lemon Squeezy as part of the deal. There is no Twitter account, no email list and no social presence to hand over.
