Who we help

GistCite for developers and AI builders

Every tool in the web app is one REST call with the same account and quota: transcripts, documents with page anchors, chunked JSON for vector stores, web extraction and Whisper.

What you can do with it

Document Extractor

Ingest documents into a RAG pipeline

Chunked JSON with page, section and character offsets, from one endpoint.

How Document Extractor does it

Web Extractor

Web pages as clean Markdown

Fetch or browser-render, with optional CSS-selector schemas for structured output.

How Web Extractor does it

YouTube Transcripts

Chapters and metadata for every video

A free metadata endpoint returns a video's chapters, description and publish date; transcripts download as Markdown, Word or JSON.

How YouTube Transcripts does it

Features that fit this work

What each one does and what it costs in units.

  • Chapters and video details

    A video's own chapters show as chips that play in the page's player and become headings in the exports. The description and publish date come along too, and the API returns them as metadata.

    Cost: Free.

Worked examples

Graduate student

From a twelve-lecture playlist and two textbooks to a searchable study corpus

Questions from this audience

How do I authenticate?
Mint an API key on the Account page and send it as a Bearer token or X-API-Key header. Keys are shown once and stored hashed.
What does a call cost?
The same units as the web app: 1 for an extraction, 10 or 30 for an AI action. Failed calls are never charged, and every metered response carries X-Quota headers.
What are the rate limits?
Requests made with an API key are limited per key, 30 a minute by default, so callers behind one address do not share a limit. Past it, requests get a 429 rate_limited error; wait a minute and retry. Sign-ins and requests without a key are limited per IP address.
