<p><b>Startup description</b></p><p>My product is a browser extension that provides real-time speech-to-text transcription and translation for livestreams, videos, meetings, and other audio content. It currently uses Deepgram APIs (Nova-3 for transcription) and Microsoft Translator API for translation, while allowing buyers to reduce costs further using alternative providers or self-hosted models.</p><p><b>Team</b></p><p>Solo founder handling:</p><ul> <li>Development</li> <li>Infrastructure</li> <li>Product</li> <li>Marketing</li> <li>Support</li> </ul> <p><b>Tech Stack</b></p><p>Infrastructure</p><ul> <li>Cloudflare Workers</li> <li>DigitalOcean</li> <li>Cloudflare D1</li> </ul> <p>AI APIs</p><ul> <li>Deepgram nova-3 api (speech-to-text) (The first 200 hours are free (great for early stage) then $0.3-$0.35/hour - can be optimized to $0.02-0.05/h (self-hosted))</li> <li>Microsoft Translator api (translation) (2M free characters/m, great for early stage - can switch to gemini 2.5 flash lite for next stage)</li> </ul> <p>Other Services</p><ul> <li>Resend (emails)</li> </ul> <p><b>Marketing and growth</b></p><p>Growth mainly came from:</p><ul> <li>Reddit posts</li> <li>AI/dev communities</li> <li>Organic discussions around affordable STT APIs</li> <li>ChatGPT (GEO)</li> </ul> <p>The project has already received interest from developers looking for cheaper transcription infrastructure.</p><p><b>Revenue and profit</b></p><p>The extension is currently in the early stage with 8 paying customers.
