Questions

Yes. Ligature Core is free forever with no limits on capture, the full Distiller, popover access, and 30 days of conversation history. Core features will never go behind a paywall.

Nothing is deleted. Your conversations, moments, and analysis stay on your device. You simply lose access to Pro features like unlimited history and projects. Renew anytime to unlock them again.

No. Ligature processes everything on your device by default. Your conversations never leave your machine unless you explicitly choose to use features like BYOK cloud processing or export.

Bring Your Own Key. Pro users can connect their own API key from Anthropic, OpenAI, or Google for higher-quality moment extraction and synthesis. When active, conversation excerpts are sent to the provider. This is opt-in and clearly indicated.

Yes. Each Pro license activates on up to 2 devices. Your data stays local to each machine since there is no cloud sync.

Claude, ChatGPT, and Gemini are supported at launch. More platforms are coming through the connector marketplace.

Not yet. Ligature is designed for individual use. Team features with shared workspaces are on the roadmap.

macOS first. Windows and Linux will follow based on demand.

Start free. Upgrade when you're ready.
