Chat Exporter

A Python tool that exports your local chats — from OpenCode (Desktop) or AntiGravity (Google) — into one single connected Markdown file, preserving every detail verbatim: user and assistant messages, CMD / PowerShell commands, tool outputs, file & search operations, and attachments.

Features

• Two chat sources: OpenCode or AntiGravity (switch from the GUI or CLI)
• Simple, clean GUI (CustomTkinter) to browse and preview conversations
• Live preview with color-coded messages (you / assistant / tools)
• Full export of each conversation into one connected Markdown file — not separate sections
• Export all conversations to a folder, or everything into a single file
• Live watch mode: automatically re-export when the source updates
• Fully equivalent command-line interface

Requirements

• Python 3.10+

Building the EXE

Easiest way: double-click build.bat

Or from PowerShell:

.\build.ps1            # onedir build (faster startup)
.\build.ps1 -OneFile   # single-file exe (easier to share)

The script handles everything automatically: creating a .venv, installing dependencies, then building with PyInstaller. Output goes to dist\.

Usage

pip install -r requirements.txt

# GUI
python run.py

# CLI — OpenCode (default)
python -m chat_exporter --cli list
python -m chat_exporter --cli export --latest

# CLI — AntiGravity
python -m chat_exporter --cli --source antigravity list
python -m chat_exporter --cli --source antigravity export --latest

Default locations

The path can be changed from the "…" button in the GUI or via --db (for AntiGravity, pass the antigravity folder containing conversations\ and brain\).

How does AntiGravity reading work?

Conversations are stored in a SQLite database with a step_payload column encoded as protobuf. The reader first tries the plain-text transcript.jsonl generated by the app under brain\<uuid>\.system_generated\logs\ (easy and readable); if not found, it decodes the protobuf directly from the database. Both paths produce identical output.

Privacy

Everything runs locally — the tool reads data on your machine and writes Markdown files only. Nothing is sent to the internet. Review exported files before sharing them; they may contain sensitive paths and data from your sessions.
