# I built a tool that turns any YouTube/TikTok video into a transcript, summary and mind map

Like many of you, I watch a lot of AI tutorials and conference talks on YouTube. The problem: a 40-minute video often contains 5 minutes of information I actually need.

So I built [SummarizeVideoToText](https://summarizevideototext.com) - paste a YouTube, TikTok or Instagram link and you get:

- The **full transcript** (searchable, copyable)
- An **AI summary** with the key points
- **Chapter breakdowns** with timestamps
- An **interactive mind map** of the content

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.

**Tech stack** for the curious: Next.js + TypeScript on Vercel, PostgreSQL for watch history, Redis for caching transcripts, SSE streaming for the summary generation.

Would love feedback from this community - especially on prompt strategies for summarizing very long transcripts without losing the details that matter.
