LTF Builder

About

LTF Builder is a lightweight Chrome extension for exporting ChatGPT conversations as LocalThink Format (.ltf.md) files.

It is designed for users who want to save long AI conversations as clean, portable, Markdown-based documents for personal knowledge management, research notes, writing workflows, and LocalThink archives.

Key features:

- Export ChatGPT conversations to .ltf.md files
- Preserve human and AI turns in a structured conversation format
- Capture long ChatGPT conversations with a targeted turn sweep
- Preserve code blocks and readable Markdown formatting
- Edit metadata such as title, language, project, tags, and visibility before download
- Download the exported file locally

Privacy:

LTF Builder does not send conversation content to any server.
It does not call LocalThink servers, OpenAI APIs, analytics services, or third-party APIs.
Conversation data stays in the browser and is only saved when the user downloads the generated .ltf.md file.

The extension only runs after the user clicks the Capture button on an active ChatGPT conversation page.

LTF Builder is not affiliated with OpenAI or ChatGPT.
