# AI Chat Exporter

A personal backup tool for ChatGPT and Claude conversation history. Exports your chats to Markdown files and syncs them to [Joplin](https://joplinapp.org/) as notes. Each conversation becomes a single `.md` file with YAML frontmatter, organised into folders that map directly to Joplin notebooks.

Supports incremental sync — only new or updated conversations are exported on each run. Every run is resumable: if interrupted, re-running picks up exactly where it left off.

---

## ⚠️ Terms of Service Warning

**Read this before using this tool.**

This tool works by accessing **unofficial, undocumented internal web API endpoints** used by the ChatGPT and Claude web apps. These endpoints are not publicly supported by OpenAI or Anthropic and are subject to change or removal without notice.

**Use of this tool may conflict with their Terms of Service:**
- OpenAI: https://openai.com/policies/terms-of-use
- Anthropic: https://www.anthropic.com/legal/consumer-terms

**By using this tool, you accept that:**
- You are using it entirely at your own risk
- Your account could potentially be suspended for automated or scripted access
- The internal APIs this tool relies on may break at any time without notice
- This tool is for **personal archival use only** — not commercial use

This tool is designed for a single user backing up their own conversations. Do not use it to scrape data at scale or for any commercial purpose.

---

## Installation

```bash
git clone <repo-url>
cd ai-chat-exporter
python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"
```

---

## First Run: Run Doctor

Before anything else, validate your setup:

```bash
python -m src.main doctor
```

This checks token presence, format, expiry, directory permissions, disk space, and live API connectivity. Fix any failures before proceeding.

---

## Getting Your Session Tokens

Session tokens are how your browser stays logged in. This tool uses them to access your chat history on your behalf.

### Token Lifetimes

| Provider | Cookie Name | Lifetime | Expiry Detection |
|----------|-------------|----------|-----------------|
| ChatGPT | `__Secure-next-auth.session-token` | ~7 days | JWT `exp` claim (decoded automatically) |
| Claude | `sessionKey` | ~30 days | Only detectable via 401 response |

### Finding Tokens in Chrome DevTools

1. Open the provider's website and make sure you're logged in
2. Press **F12** (Windows/Linux) or **Cmd+Option+I** (macOS) to open DevTools
3. Click the **Application** tab
4. In the left panel, expand **Cookies** and click the site URL
5. Find the cookie by name and copy its **Value**

**ChatGPT:** go to `https://chatgpt.com` → find `__Secure-next-auth.session-token` → copy Value (starts with `eyJ`)

**Claude:** go to `https://claude.ai` → find `sessionKey` → copy Value

### When Tokens Expire

When a token expires you'll see a `401 Unauthorized` error. To refresh:
- Re-run the `auth` wizard: `python -m src.main auth`
- Or manually update the value in your `.env` file

---

## The `auth` Command

The easiest way to configure tokens is the interactive wizard:

```bash
python -m src.main auth
```

This walks you through finding your token, validates it, shows the expiry date (ChatGPT only), and offers to write it to your `.env` automatically. Tokens are never echoed to the terminal.

---

## `.env` Setup

Copy `.env.example` to `.env` and fill in your values:

```bash
cp .env.example .env
```

### Provider tokens

| Variable | Description |
|----------|-------------|
| `CHATGPT_SESSION_TOKEN` | Your ChatGPT JWT session token (`eyJ…`) |
| `CHATGPT_PROJECT_IDS` | Comma-separated ChatGPT project IDs (see below) |
| `CLAUDE_SESSION_KEY` | Your Claude session key |

### Output

| Variable | Default | Description |
|----------|---------|-------------|
| `EXPORT_DIR` | `./exports` | Where to write exported Markdown files |
| `OUTPUT_STRUCTURE` | `provider/project/year` | Folder structure (see below) |

### Joplin

| Variable | Default | Description |
|----------|---------|-------------|
| `JOPLIN_API_TOKEN` | — | Authorization token from Joplin Web Clipper settings |
| `JOPLIN_API_URL` | `http://localhost:41184` | Joplin API URL (change only if you've customised the port) |
| `JOPLIN_REQUEST_TIMEOUT` | `30` | Seconds before an API call times out. Increase for very large conversations. |

### Cache & logging

| Variable | Default | Description |
|----------|---------|-------------|
| `CACHE_DIR` | `~/.ai-chat-exporter` | Where to store the sync manifest |
| `LOG_FILE` | `~/.ai-chat-exporter/logs/exporter.log` | Log file path (`none` to disable) |

---

## ChatGPT Projects

ChatGPT project conversations are stored separately from your main conversation list and require extra configuration.

### Finding your project IDs

1. Open ChatGPT and click a Project in the left sidebar
2. Look at the browser URL — it will look like:
   `https://chatgpt.com/g/g-p-68c2b2b3037c8191890036fb4ae3ed9f-my-project/project`
3. Copy the `g-p-…` part (everything up to but not including the slug after the second `-`)

Add all your project IDs to `.env` as a comma-separated list:

```
CHATGPT_PROJECT_IDS=g-p-68c2b2b3037c8191890036fb4ae3ed9f,g-p-anotherprojectid
```

The `auth` wizard can also guide you through this step interactively.

---

## Output Structure

All exported files go under `EXPORT_DIR`. The folder structure maps directly to Joplin notebooks.

### Default: `provider/project/year`

```
exports/
├── chatgpt/
│   ├── no-project/
│   │   └── 2024/
│   │       └── 2024-03-15_my-conversation_abc12345.md
│   └── learning-python/
│       └── 2024/
│           └── 2024-03-15_async-tutorial_def67890.md
└── claude/
    ├── no-project/
    │   └── 2024/
    │       └── 2024-06-01_docker-explained_ghi11111.md
    └── startos-packaging/
        └── 2024/
            └── 2024-06-10_manifest-setup_jkl22222.md
```

### Joplin Notebook Mapping

Each provider+project combination maps to a flat Joplin notebook created automatically by the `joplin` command:

| Export folder | Joplin notebook |
|---------------|-----------------|
| `exports/chatgpt/learning-python/` | `ChatGPT - Learning Python` |
| `exports/claude/startos-packaging/` | `Claude - Startos Packaging` |
| `exports/chatgpt/no-project/` | `ChatGPT - No Project` |
| `exports/claude/no-project/` | `Claude - No Project` |

### Other `OUTPUT_STRUCTURE` options

| Value | Result |
|-------|--------|
| `provider/project/year` (default) | `exports/claude/my-project/2024/file.md` |
| `provider/project` | `exports/claude/my-project/file.md` |
| `provider/year` | `exports/claude/2024/file.md` (projects ignored) |

### Filename format

`YYYY-MM-DD_{title-slug}_{id[:8]}.md` — e.g. `2024-06-10_manifest-setup_jkl22222.md`

---

## CLI Reference

### Global flags

```
--verbose / -v     DEBUG output to console
--quiet / -q       WARNING and above only
--debug            DEBUG + full tracebacks + redacted API response bodies
--no-log-file      Disable file logging
--version          Print version and exit
```

### `auth` — Interactive token setup

```bash
python -m src.main auth
```

Guided wizard to find and save session tokens and ChatGPT project IDs. Detects OS and shows the correct DevTools shortcut.

### `doctor` — Health check

```bash
python -m src.main doctor
```

Checks: token presence, JWT validity and expiry, directory permissions, disk space, live API reachability. Exits with code 0 if all pass, 1 if any fail.

### `export` — Export conversations

```bash
# Export everything (new/updated only)
python -m src.main export

# Single provider
python -m src.main export --provider claude

# JSON output
python -m src.main export --format json

# Both Markdown and JSON
python -m src.main export --format both

# Only conversations updated since a date
python -m src.main export --since 2024-06-01

# Only conversations in a specific project (case-insensitive substring)
python -m src.main export --project "learning python"

# Only conversations outside any project
python -m src.main export --project none

# Write to a custom directory
python -m src.main export --output /path/to/my/notes

# Preview without writing anything
python -m src.main export --dry-run
```

Options: `--provider [chatgpt|claude|all]`, `--format [markdown|json|both]`, `--output PATH`, `--since YYYY-MM-DD`, `--project NAME`, `--dry-run`

### `list` — List conversations

```bash
# List all conversations for all providers
python -m src.main list

# Single provider
python -m src.main list --provider chatgpt

# Filter by project
python -m src.main list --project "learning python"

# Only conversations outside any project
python -m src.main list --project none
```

Fetches and displays all conversations without exporting them. Useful for verifying what the tool can see before running an export.

### `joplin` — Sync to Joplin

```bash
# Sync all pending conversations to Joplin
python -m src.main joplin

# Preview what would be synced without sending anything
python -m src.main joplin --dry-run

# Sync a single provider
python -m src.main joplin --provider chatgpt

# Sync only conversations in a specific project
python -m src.main joplin --project "learning python"

# Sync only conversations outside any project
python -m src.main joplin --project none
```

Reads the local export cache and pushes each exported Markdown file to Joplin as a note. Notebooks are created automatically. Re-running is safe — notes are updated (not duplicated).

**Prerequisites:**
1. Run `export` first to generate the Markdown files
2. Open Joplin → Tools → Options → Web Clipper → enable the service
3. Copy the Authorization token and add `JOPLIN_API_TOKEN=<token>` to your `.env`
4. Joplin desktop must be open when you run this command

Options: `--provider [chatgpt|claude|all]`, `--project NAME`, `--dry-run`

### `cache` — Manage the sync manifest

```bash
# Show statistics
python -m src.main cache --show

# Clear all cached entries (forces full re-export next run)
python -m src.main cache --clear

# Clear a single provider
python -m src.main cache --clear --provider claude
```

---

## How the Cache Works

The cache manifest lives at `~/.ai-chat-exporter/manifest.json` and records every exported conversation: its title, project, `updated_at` timestamp, output file path, and (after Joplin sync) the Joplin note ID.

On every `export` run:
1. Fetch the full conversation list from the provider
2. Compare each conversation's `updated_at` against the manifest
3. Export only conversations that are new or have been updated
4. Write each successfully exported conversation to the manifest **immediately** (not batched)

On every `joplin` run:
1. Read the manifest to find conversations not yet synced to Joplin, or re-exported since last sync
2. Push each pending Markdown file to Joplin (create or update)
3. Store the Joplin note ID in the manifest so subsequent runs update rather than duplicate

**This design makes every run inherently resumable.** If the tool is interrupted for any reason — rate limit, network drop, Ctrl+C, crash — simply re-run the same command. It will skip already-processed conversations and continue from where it stopped.

To force a full re-export: `python -m src.main cache --clear` then re-run export.

---

## Troubleshooting

### `401 Unauthorized`
Your session token has expired.
- Run `python -m src.main auth` to get a new token interactively
- Or manually copy a fresh cookie value into your `.env` file

Note: Claude's `sessionKey` is an opaque string — the only way to know it's expired is the 401 error. ChatGPT JWTs have an `exp` claim that the `doctor` command can decode and display.

### `429 Rate Limited`
The tool automatically pauses, saves progress, and exits with a clear message showing how many conversations were exported vs remaining. Just re-run the same export command to resume — the cache picks up exactly where it left off.

### Joplin: "JOPLIN_API_TOKEN is not set"
You need to configure the token before running the `joplin` command:
1. Open Joplin desktop
2. Go to Tools → Options → Web Clipper
3. Enable the Web Clipper service
4. Copy the Authorization token shown on that page
5. Add `JOPLIN_API_TOKEN=<token>` to your `.env` file

### Joplin: "Joplin is not responding"
Joplin desktop must be running when you run the `joplin` command. The Web Clipper service shuts down when Joplin is closed.

### Joplin: "Joplin rejected the API token (HTTP 401)"
The token in `JOPLIN_API_TOKEN` doesn't match what Joplin expects. Get a fresh token from Joplin → Tools → Options → Web Clipper → Authorization token.

### Joplin: note timed out
If you see a timeout error, Joplin took longer than `JOPLIN_REQUEST_TIMEOUT` seconds (default: 30) to respond. Possible causes:
- The conversation is very large and Joplin is slow to index it
- Joplin is busy syncing or loading a large library
- Joplin has frozen — try restarting it

To increase the timeout: add `JOPLIN_REQUEST_TIMEOUT=60` to your `.env`.

### ChatGPT project conversations not appearing
Make sure you've added the project IDs to `CHATGPT_PROJECT_IDS` in your `.env`. See [ChatGPT Projects](#chatgpt-projects) for how to find them. Project conversations are not included in the default conversation listing — they must be fetched separately.

### Schema warnings in logs (`Unexpected API response shape`)
The provider's internal API may have changed. Run with `--debug`, sanitize the output (remove any personal content), and check the project's GitHub Issues for known fixes.

### Non-text content warnings
Images, code interpreter outputs, DALL-E generations, and Claude artifacts are not exported in v0.2.0. A WARNING is logged for each skipped item. See `FUTURE.md` for the roadmap.

### Empty export / all conversations skipped
No new or updated conversations since your last run. To verify: `python -m src.main cache --show`. To force a full re-export: `python -m src.main cache --clear`.

### Filing a bug report
1. Run with `--debug`: `python -m src.main export --debug 2>&1 | tee debug.log`
2. Remove any personal conversation content from `debug.log`
3. Open a GitHub Issue with the sanitized log and the exact command you ran

---

## Future Work

See `FUTURE.md` for planned features:

- **v0.2.x** — `export --force` flag; `joplin --force` flag; per-conversation cache reset
- **v0.3.0** — Official API fallback: parse export ZIP files from ChatGPT/Claude settings
- **v0.4.0** — Rich content: images, artifacts, code interpreter output, extended thinking
- **v0.5.0** — Watch/scheduled mode; Obsidian vault output

---

## Security Notes

- All exported data is stored **locally only** — nothing is sent anywhere except to your local Joplin instance
- Exported files and the cache manifest are created with `600` permissions (owner read/write only)
- `.env` is in `.gitignore` — **never commit it**
- Session tokens are never logged, printed, or included in error messages
- The Joplin API token is only ever sent to `localhost` — it never leaves your machine
- If you accidentally commit `.env`: immediately log out and back in to invalidate the token, then remove it from git history using [BFG Repo Cleaner](https://rtyley.github.io/bfg-repo-cleaner/) or `git filter-branch`
