chat-history 0.3.2

Local UI and tooling for browsing ChatGPT and Claude history exports

Chat History

Browse and export your ChatGPT and Claude conversations locally.

Getting Started

Requires Python 3.11+ and uv.

1. Export your chats from ChatGPT or Claude (Settings → Export data). Both services send a ZIP file by email.

2. Create a folder for your chat history, save the ZIP there, and open a terminal in that folder. The wizard will store all data inside it.

3. Run the setup wizard:

   uvx chat-history
   

   The wizard finds your export files, configures everything, and opens the browser.

Next time, run uvx chat-history in the same folder to start browsing. To update to the latest version, run uvx chat-history install.

To export all conversations as markdown (useful for feeding to other AI tools):

uvx chat-history export

Features

• Unified conversation browser for ChatGPT and Claude exports
• Provider-aware favorites and external links
• Full-text search with optional semantic search (OpenAI embeddings + FAISS)
• Activity and token statistics
• Export conversations to markdown for downstream AI workflows

CLI Reference

All commands work as uvx chat-history <command> or, if installed locally, chat-history <command>.

Command	Description
(none)	Start server if configured, otherwise run setup wizard
init	Run the interactive setup wizard
serve	Start the web server
export	Export conversations to markdown
inspect	Print conversation and message counts
install	Reinstall chat-history via uvx --reinstall chat-history

serve

uvx chat-history serve [--host 127.0.0.1] [--port 8080] [--no-browser]

export

uvx chat-history export [--provider chatgpt|claude|all] [--out DIR] [--clean]
                        [--exclude-system] [--exclude-tool]
                        [--exclude-thinking] [--exclude-attachments]

• --clean removes old export files before writing (scoped to --provider if set)
• Default output: ./data/export/{chatgpt|claude}/

init

uvx chat-history init [--path DIR]

Scans the current folder and ~/Downloads for export ZIPs, validates them, extracts to ./data/, writes ./data/.env, and offers to start the server. Supports adding a second provider to an existing setup.

Configuration

All config lives in ./data/.env (created by the wizard or manually):

Variable	Default	Description
CHAT_HISTORY_DATA_DIR	data	Root directory for derived data
CHAT_HISTORY_CHATGPT_PATH	—	Path to ChatGPT export folder or conversations.json
CHAT_HISTORY_CLAUDE_PATH	—	Path to Claude export folder or conversations.json
CHAT_HISTORY_OPENAI_ENABLED	false	Enable semantic search
OPENAI_API_KEY	—	Required if semantic search is enabled
OPENAI_ORGANIZATION	—	Optional OpenAI org
OPENAI_EMBEDDING_MODEL	text-embedding-3-small	Embedding model for semantic search
CHAT_HISTORY_SETTINGS_DB_PATH	—	Override path for settings SQLite DB

Developer Setup

make install    # uv sync
make dev        # uvicorn with hot-reload on :8080
make test       # run tests

Install as a global command from the local repo (editable, changes reflected immediately):

make tool-install         # uv tool install -e .
chat-history              # works from any directory
make tool-uninstall       # uv tool uninstall chat-history

Notes

• Export is non-destructive by default. Existing files remain unless --clean is used.
• Token stats for Claude are approximate (fallback tokenizer), not exact Claude-native counts.
