Save your files.
Drag a web link from Chrome, Edge, or Safari into the Documents/Lectic Inbox folder on your computer, or tell your AI: “Save this video for later.”
Local files on your computer
Save videos and notes so your AI can quote them.
Lectic saves YouTube videos, transcripts, and text notes in a folder on your computer. When you ask your AI a question, it searches those files, writes an answer based on what you saved, and shows you the exact quote and timestamp.
Free and open source. Works with Claude Code, OpenAI Codex, and ChatGPT on Windows, macOS, and Linux.
Ask questions.
Ask your AI: “What does my debugging video say about this error?” Your AI searches your saved files and quotes the exact lines in its answer.
Share with other people.
Run lectic pack to put your saved notes and quotes into a single .lectic file. Send that file to a coworker so their AI can search the same material.
Features
What you can do with Lectic.
Lectic keeps your files organized so your AI can find them and use them in any conversation.
Shareable files
The .lectic file format
A single file that holds your notes, transcripts, and quotes. You can send it to another person so their AI has access to the same material.
Desktop folder
Documents/Lectic Inbox
A normal folder on your computer where you can drop web links and text files. Lectic reads them without running a background app.
Checked quotes
The verify command
Run lectic verify to check that every quote in your collection matches the original source text. If a file was changed or deleted, Lectic alerts you.
AI connection
Works with Claude and ChatGPT
Lectic connects to Claude Code, OpenAI Codex, and ChatGPT through the Model Context Protocol, an open standard for AI tools.
Sample files
An example you can inspect.
Lectic includes a sample debugging transcript with three quoted sentences. Choose an example below to see how your AI uses the saved text.
Question asked to AI
Change the parser and delimiter settings together, then ship after one successful file.
Uses three procedures from the saved lesson.
What your AI answers
Use one controlled experiment at a time.
- Record the smallest failing input, expected output and actual output.
- Change one suspected cause. Revert an ineffective change before testing the next hypothesis.
- Keep the original reproducer and check at least one nearby boundary before shipping.
Setup
Connect Lectic to your AI.
If you use Claude Code or OpenAI Codex, paste this into your chat. Your assistant downloads Lectic and connects to it automatically:
Set up Lectic for me: https://github.com/tyreamer/lectic
Restart your assistant once when it finishes, then ask it to run the sample test:
Try Lectic with its offline debugging starter.
Details
What Lectic can and cannot do.
Lectic checks that quotes match the text in your saved files. It does not check whether the advice in a video or article is correct. You still need to read what your AI quotes and use your own judgement.
Lectic reads text notes, transcripts (.txt, .md, .vtt, .srt), and YouTube captions. General web articles are saved as links; Lectic does not scrape full text from general websites. PDF, image, audio, and video files are kept as attachments.
All files stay on your computer in the .lectic folder. Nothing is uploaded to a cloud server unless you choose to share a file.
