Export an LLM chat to Markdown, HTML, or PDF
Chat UIs make it hard to get a clean, portable copy of a conversation. This tool takes a pasted transcript — or a raw message JSON array — parses it into turns, and exports it as Markdown, standalone HTML, or a print-ready page you can save to PDF. Everything happens in your browser.
How it works
The parser supports two inputs:
- Role-labeled text — it scans for lines beginning with a known role label
(
User:,Assistant:,Human:,System:,AI:) and groups the lines that follow into that turn. This matches how most people copy a chat. - Message JSON — an array of
{ "role": "...", "content": "..." }objects (the OpenAI / Anthropic request shape). Each object becomes a turn.
Once parsed, the conversation is re-rendered into the chosen format:
- Markdown uses
**Role:**headers and preserves the body text verbatim. - HTML wraps each turn in a styled block with role coloring.
- Print view opens a clean, paginated page in a new tab where you can use Save as PDF.
Tips and notes
- If turns merge into one block, your paste is missing role labels — add them or switch to the JSON message format.
- The HTML export is self-contained (inline styles), so you can save the file and open it anywhere without a stylesheet.
- For PDF we deliberately use the browser’s own print engine rather than a bundled library — it is lighter, renders fonts correctly, and keeps your data fully local.
