Claude & ChatGPT

Connect your INDXR library to an AI assistant, and next to everything it already knows and can look up, it can search your own transcripts and quote the passage and the minute it was said. The connection can only read your library, never change it, and it is free on every account.

Before you connect

You need a free INDXR account with a few sources in it: a lecture playlist, the interviews behind an article, the talks you are drawing on for a book. YouTube captions cost nothing, and a new account comes with 10 credits for AI transcription.

Create a free account

What the assistant can do

  • List your collections, with how many transcripts each holds.
  • Search your library: titles, channels and the transcript text itself. Each hit comes with a short excerpt, its timestamp and a link to that moment in the video.
  • Read a transcript in blocks of up to 30 minutes, with timestamps and speaker names. If you edited a transcript, it reads your edited version.
  • Look up the source: channel, link, length, language, publication date, and a ready APA 7 citation.
  • Read a summary you already made. It never creates one, so it never spends credits.

What it cannot do

It cannot add, edit or delete anything, spend credits, or see your account, payments or anyone else's library. It sees only what it asks for: the search results and transcript blocks it needs to answer you. Your audio never leaves INDXR, because there is none: audio is deleted after transcription.

Connect Claude

Works on every Claude plan (the Free plan allows one custom connector). Add it on claude.ai or in Claude Desktop; after that it also works in the Claude mobile apps.

  1. Open Customize → Connectors.
  2. Click + Add, then Add custom connector.
  3. Name it INDXR and paste this URL, then continue:
https://app.indxr.ai/api/mcp
  1. Choose to sign in, click Add, then Connect. Sign in to INDXR and click Allow.
  2. In a chat, open + → Connectors and turn INDXR on.

On a Team or Enterprise plan, an owner may have to add the connector for the organisation first.

Connect Claude Code

Add the server once, then sign in from the MCP menu:

claude mcp add --transport http indxr https://app.indxr.ai/api/mcp

Then run /mcp in Claude Code, choose indxr and sign in.

Connect ChatGPT

ChatGPT connects to your own servers through developer mode, on paid plans (Plus, Pro, Business, Enterprise, Edu) and on the web only. Developer mode is still a beta at OpenAI, and its menus move now and then: if a step looks different, OpenAI's help pages have the current path.

  1. Open Settings → Apps & Connectors → Advanced and switch on Developer mode.
  2. Back on the connectors page, click Create. Name it INDXR, paste the URL above and choose OAuth as authentication.
  3. Save, click Connect, sign in to INDXR and click Allow.
  4. In a new chat, open + → Developer mode and select INDXR.

Questions that work well

Name the collection or the source when you can, and ask for quotes. For example:

  • “In my Death course, what does Kagan say about the soul? Quote him with timestamps.”
  • “Turn lectures 6 to 10 of my Early Middle Ages collection into study notes, with a citation per section.”
  • “Which of my sources mention Charlemagne? Give me the APA references.”

Limits

Up to 60 requests a minute per account. Long transcripts are read in blocks of 15 minutes by default (30 at most), so the assistant fetches a long lecture in a few steps.

Disconnect

Remove the INDXR connector in Claude or ChatGPT and its access ends. To revoke it from INDXR's side too — every token that app ever got — go to Settings → Connected apps and click Disconnect. What the assistant read during a chat is kept by that provider under its own terms.
