The problem: a 40-minute video often contains 5 minutes of information I actually need.</p> <p>So I built <a href="https://summarizevideototext.com" rel="noopener noreferrer">SummarizeVideoToText</a> - paste a YouTube, TikTok or Instagram link and you get:</p> <ul> <li>The <strong>full transcript</strong> (searchable, copyable)</li> <li>An <strong>AI summary</strong> with the key points</li> <li> <strong>Chapter breakdowns</strong> with timestamps</li> <li>An <strong>interactive mind map</strong> of the content</li> </ul> <p>It streams results in seconds and is free to start - 2 videos/day without sign-up (up to 15 min), 10/day with a free Google login, and a Pro tier ($5/mo) for long videos up to 6 hours.</p> <p><strong>Tech stack</strong> for the curious: Next.js + TypeScript on Vercel, PostgreSQL for watch history, Redis for caching transcripts, SSE streaming for the summary generation.</p> <p>Would love feedback from this community - especially on prompt strategies for summarizing very long transcripts without losing the details that matter.</p> ai llm
