Does this project support command line mode to export and exit? I need command line options to

export all chat history into md formats (archived into zip file) either all time or since last update to a user provided folder (if not given fall back to the current working directory). Use what's already implemented in this project instead of adding new features. If you are sure there are no such features then implement them, update README accordingly, then let me know at the end what you've done. Make sure README is properly formatted and written in a fool-proof way for usage without writing too much. This project is licensed under Boost Software License 1.0. This project was inspired by https://github.com/thomas-pedersen/cursor-chat-browser which was written in node js and not updated for 4 months at the time of this project creation, so for better maintainability we created a python project and added multiple features to enhance it.

Great, so the project already has CLI support via scripts/export.py. Let me now read the key files to understand exactly what's implemented and what might need to be added or modified:

scripts/export.py - the CLI export script
README.md - current README
api/export_api.py - the web API export

The user wants:

Export all chat history into md formats archived into zip file
Either all time or since last update
To a user provided folder (fallback to cwd)
Use what's already implemented

Let me read these files to see what's there and what needs to be done.

# Cursor Chat Browser (Python)

A Python web application for browsing and managing chat histories from the Cursor editor's AI chat feature. This is a Python port of the original [cursor-chat-browser](https://github.com/thomas-pedersen/cursor-chat-browser) Node.js project.

## Features

- Browse and search all workspaces with Cursor chat history
- Support for both workspace-specific and global storage (newer Cursor versions)
- View AI chat and Composer/Agent logs
- Organize chats by workspace/project
- Full-text search with filters for chat/composer logs
- Responsive design with dark/light mode support
- Export chats as:
  - Markdown files
  - HTML documents (with syntax highlighting)
  - PDF documents
  - JSON files
  - CSV files
- Daily bulk export: CLI or UI export of all chats (or only new since last run)
- Syntax highlighted code blocks
- Bookmarkable chat URLs
- Automatic workspace path detection

## Prerequisites

- Python 3.10+
- A Cursor editor installation with chat history

## Installation

1. Navigate to the project directory:
   ```bash
   cd cursor-chat-browser-python
Create a virtual environment (recommended):
python -m venv venv
# Windows
venv\Scripts\activate
# macOS/Linux
source venv/bin/activate
Install dependencies:
pip install -r requirements.txt
Start the server:
python app.py
Open http://localhost:3000 in your browser
Configuration

The application automatically detects your Cursor workspace storage location based on your operating system:

Windows: /home/user/AppData/Roaming/Cursor/User/workspaceStorage

WSL2: /home/user/AppData/Roaming/Cursor/User/workspaceStorage

macOS: ~/Library/Application Support/Cursor/User/workspaceStorage

Linux: ~/.config/Cursor/User/workspaceStorage

Linux (remote/SSH): ~/.cursor-server/data/User/workspaceStorage

If automatic detection fails, you can manually set the path in the Configuration page (gear icon).

You can also set the path via environment variable:
export WORKSPACE_PATH="/path/to/cursor/workspaceStorage"
python app.py
CLI Export

Export all chats or only new ones since last run:
# Export everything
python scripts/export.py --since all --out ./export

# Export only new/updated since last
python scripts/export.py --since last --out ./export

# Include composer logs
python scripts/export.py --since all --out ./export --include-composer
Output is one Markdown file per chat under export/YYYY-MM-DD/<workspace_slug>/chat/<timestamp>__<title>__<log_id>.md, with YAML frontmatter and full transcript.

Export state is stored in /home/user/.cursor-chat-browser/export_state.json so incremental export works consistently.

Now I have a clear picture. Let me analyze what exists and what needs to be added:

What already exists:

scripts/export.py - CLI export that writes individual markdown files to disk, organized by date/workspace/chat
api/export_api.py - Web API export that creates a ZIP file with markdown files

What the user wants:

CLI command to export all chat history into markdown format, archived into a zip file
Options: --since all (all time) or --since last (since last update)
Output to user-provided folder, fallback to current working directory
The CLI currently writes individual files but doesn't zip them, while the web API does. I need to add --zip flag support to the CLI export script and change the default output directory from ./export to . (current working directory).
I should also update the README with the proper license and inspiration note.

Looking back at the requirements, the user wants zip archiving as a core feature of the export functionality. I'm thinking the --zip flag should be the primary way to export, with an option to keep individual files if needed. The zip file should have a sensible name like cursor-export-YYYY-MM-DD.zip to make it easy to identify exports by date.

Now I need to implement this: add the --zip flag to the export script, handle the compression logic when that flag is used, adjust the default output directory, and update the documentation accordingly. I can reference the existing compression pattern from the API module to keep things consistent. Modifying the argument parser and main export flow to support zip mode while keeping the default file-writing behavior intact. I need to add the --zip flag handling and restructure the export loop to collect content in memory first, then decide whether to write individual files or create a zip archive at the end. I need to refactor how the code handles file writing to support both individual file output and zip mode. Instead of writing files during the loop, I'll collect all the content in a list of path-content pairs, then decide at the end whether to write individual files or create a zip archive. This defers the actual writing until after processing is complete, which is cleaner and avoids partial writes if an error occurs.

Refactoring the export logic... Writing the export logic...

I need to add the zipfile import to the existing imports, then update the README to reflect the license change to Boost Software License 1.0, add a note about the Node.js inspiration, document the new --zip flag in the CLI section, and consider adding --help support for better usability.

Now I have a clear picture. Let me analyze what exists and what needs to be added:

Python)

A Python web application for browsing and managing chat histories from the Cursor editor's AI chat feature. View, search, and export your AI conversations in various formats.

Inspired by [cursor-chat-browser](https://github.com/thomas-pedersen/cursor-chat-browser) (Node.js). This Python rewrite was created for easier maintenance and to add additional features such as CLI zip export, richer Markdown frontmatter, and a zero-build-step frontend.

## Features

- Browse and search all workspaces with Cursor chat history
- Support for both workspace-specific and global storage (newer Cursor versions)
- View AI chat and Composer/Agent logs
- Organize chats by workspace/project
- Full-text search with filters for chat/composer logs
- Responsive design with dark/light mode support
- Export chats as Markdown, HTML, PDF, JSON, or CSV
- **CLI export** with zip archive support and incremental (`--since last`) mode
- Syntax highlighted code blocks
- Bookmarkable chat URLs
- Automatic workspace path detection

## Prerequisites

- Python 3.10+
- A Cursor editor installation with chat history

## Installation

```bash
cd cursor-chat-browser-python
python -m venv venv

# Windows
venv\Scripts\activate
# macOS / Linux
source venv/bin/activate

pip install -r requirements.txt
Quick Start (Web UI)
python app.py
Open http://localhost:3000 in your browser.

CLI Export

Export chat history to Markdown without starting the web server.
# Show all options
python scripts/export.py --help

# Export every chat as a zip archive into the current directory
python scripts/export.py --zip

# Export only chats updated since the last export, save zip to a specific folder
python scripts/export.py --since last --zip --out /path/to/folder

# Export as individual Markdown files (no zip) into ./my-export
python scripts/export.py --out ./my-export
CLI Options

Flag Description Default

--since all Export all chats all

--since last Export only chats updated since last export

--out DIR Output directory . (current directory)

--zip Archive all Markdown files into cursor-export-YYYY-MM-DD.zip off

--include-composer Include composer logs off

--help Show help and exit

Output

Zip mode (--zip): A single cursor-export-YYYY-MM-DD.zip file containing all Markdown files organized by date, workspace, and chat.

File mode (default): Individual Markdown files at <out>/YYYY-MM-DD/<workspace>/chat/<timestamp>__<title>__<id>.md, plus a manifest.jsonl index.

Each Markdown file includes YAML frontmatter (log ID, title, timestamps, message count, model, token usage, etc.) and the full conversation transcript.

Export state is saved to /home/user/.cursor-chat-browser/export_state.json so that --since last works across runs.

Configuration

The application automatically detects your Cursor workspace storage location:

| OS | Path

Flag	Description	Default
`--since all`	Export all chats	`all`
`--since last`	Export only chats updated since last export
`--out DIR`	Output directory	`.` (current directory)
`--zip`	Archive all Markdown files into `cursor-export-YYYY-MM-DD.zip`	off

Everything works. Here's a summary of what was done:

The project already had CLI export support. The existing scripts/export.py could export all chats to individual Markdown files, but it lacked zip archive support. Here's what I changed:

Changes to `scripts/export.py`

Added --zip flag -- when passed, all Markdown files are archived into a single cursor-export-YYYY-MM-DD.zip file in the output directory instead of writing individual files to disk.
Added --help / -h flag -- prints usage information and exits.
Changed default output directory from ./export to . (current working directory), so if --out is omitted the zip/files go to wherever you run the command from.
Refactored the main loop to collect exported entries in memory before writing, so the zip path and the individual-files path share the same data.

Changes to `README.md`

License updated from MIT to Boost Software License 1.0.
Inspiration note added at the top, crediting the original Node.js cursor-chat-browser project with context about why this Python version was created.
CLI Export section rewritten with a clear options table, examples for zip and file modes, and description of the output format.
Removed the "Differences from the Node.js Version" comparison table (redundant given the inspiration note) and trimmed overall verbosity.

No new dependencies were added -- `zipfile` is part of the Python standard library.

If some parameters are not given, assume the biggest export as much as possible by default. Rename parameters appropriately and change their implementation accordingly.

Thinking (8.9s)

The user wants me to change the default behavior so that when parameters are not given, it exports as much as possible. Let me think about what this means:

--since defaults to all - this is already the biggest export, good.
--zip is off by default - the user wants zip to be on by default (biggest/most complete export).
--include-composer is off by default - the user wants this on by default (biggest export).

So the logic should be inverted:

Instead of --zip (opt-in), it should be --no-zip (opt-out) - zip by default
Instead of --include-composer (opt-in), it should be --no-composer or --exclude-composer (opt-out) - include composer by default
--since all is already the default, that's fine

Now I need to go back and update the script to flip these defaults and rename the flags accordingly.

Done. Here's what changed:

Defaults are now "export as much as possible":

Zip is now on by default (was opt-in via --zip). Use --no-zip to opt out.
Composer logs are now included by default (was opt-in via --include-composer). Use --no-composer to exclude them.
--since all and --out . were already the biggest defaults and remain unchanged.

Renamed flags:

Old	New	Reason
`--zip`	(default)	Zip is now the default behavior
(none)	`--no-zip`	Opt out of zip
`--include-composer`	(default)	Composer logs included by default
(none)	`--no-composer`	Opt out of composer logs

So python scripts/export.py with zero arguments now gives you the maximum export: all chats, all composer logs, zipped, in the current directory.

The issue is that b.get("createdAt") can be an ISO date string (not just an epoch integer). The or chain on line 443 picks the first truthy value, which may be a string like "2025-01-15T...". Then line 483 tries to divide that string by 1000.

I need a helper to safely coerce any timestamp value to epoch milliseconds (int), matching what api/export_api.py does with to_epoch_ms(). The same risk exists on lines 453, 456, 460, and 464.

There's already a robust to_epoch_ms() in the utils. The CLI script has its own inline helpers instead of using it. I'll add a local _to_epoch_ms function in the script (it's standalone and doesn't import from utils/) and use it everywhere a timestamp could be a string.

I need to fix all lines where raw timestamp values from the database are used in arithmetic. I'll apply to_epoch_ms() at every point where a timestamp enters the pipeline.

  --since all|last   Export all chats or only those updated since last export.
                     Default: all
  --out DIR          Output directory. Default: current working directory (.)
  --no-zip           Write individual Markdown files instead of a zip archive.
  --no-composer      Exclude composer logs (export only chat logs).

The fix is straightforward. The root cause was that Cursor's database stores timestamps in mixed formats -- sometimes as epoch integers, sometimes as ISO 8601 strings like "2026-02-03T20:39:54.017Z". The script was using raw or chains (e.g., b.get("createdAt") or b.get("timestamp")) which could yield a string, then dividing it by 1000 as if it were a number.

I added a to_epoch_ms() helper (matching the one already in utils/path_helpers.py) and wrapped every timestamp read from the database through it:

Line 420: updated_at from lastUpdatedAt / createdAt
Line 467: bubble createdAt / timestamp
Line 477: code block diff timestamps
Line 487: frontmatter created_at

All timestamps are now normalized to integer epoch milliseconds before any arithmetic.
