# Transcript Guru

> YouTube transcript extraction, AI summaries, 75+ language translations, chapter generation, mind maps, and content repurposing. Available as a web app, Chrome extension, and developer API.

Transcript Guru turns any YouTube video into searchable, translatable, and repurposable content. YouTube caption transcripts are unlimited and free for anonymous visitors. Registered accounts get AI features metered in credits. Paid plans unlock audio uploads (AI speech recognition), bulk extraction up to 500 videos, and programmatic API access.

## Core concepts

- **Transcript**: time-stamped caption or ASR segments for a YouTube video. Available via the Chrome extension (in-page panel) or the web dashboard.
- **Job**: a server-side processing unit. Creating a job produces a `job_id` you can use to request summary, chapters, translation, or repurposed content.
- **Credit**: unit of metered AI work. See Pricing for cost breakdowns.
- **Share link**: a public, read-only URL for a transcript you have produced.

## Developer API

The REST API is under `https://transcriptguru.io/api/v1/` and accepts `Authorization: Bearer tg_live_<key>`. Keys are generated from the dashboard (Settings → API Keys) on the Free, Basic, Pro, or Enterprise plans. Free sandbox quota: 100 requests/day, 1,000/month, enough to prototype and test the full MCP + REST surface without a credit card. The anonymous `/public/transcript/{video_id}` endpoint is unlimited for YouTube caption fetches and requires no signup; an IP rate limit of 60 requests/hour keeps crawlers in check.

## Crawler-friendly transcript pages (no JS required)

These endpoints return semantic HTML with inline JSON-LD VideoObject, suitable for LLM browsing tools and non-JS crawlers. The main SPA routes (`/preview`, `/shared`, `/reader`) remain the canonical destination for human readers.

- `GET /llm/shared/{token}` — full shared transcript as HTML.
- `GET /llm/preview/{video_id}` — first 15 segments as HTML (matches the gated SPA preview).
- `GET /llm/transcript/{video_id}` — full public transcript as HTML when the video has captions.
