Bolt by Sparcle

Masks sensitive data before it reaches AI chat sites, and connects your browser to Bolt for search, autofill, and quick access.

Bolt is the browser companion to the Bolt desktop app. It does two things. It protects what you send to AI sites. When you paste, type or attach something on ChatGPT, Claude, Gemini, Copilot or Perplexity, Bolt checks it first for things like card numbers, account numbers, national IDs and secrets, and offers to mask them before they leave your computer. Low risk findings pass with a note. High risk content stops and asks. You can always continue. It connects your browser to Bolt. Search your open tabs and your Bolt from the address bar (type b and a space) or from a new tab. Fill and save logins, passkeys and one-time codes from your Bolt vault. Send a page or a selection to Bolt as a note, or ask Bolt about it, from the right-click menu. How it works: - The extension talks only to the Bolt app on your own computer. The checking and masking happen there. - No telemetry. No account required. - Nothing you type, paste or browse is sent to Sparcle. - Companies can configure it with managed policy, including turning features on or off and choosing which AI sites are guarded. Requires the Bolt desktop app for macOS or Windows (Linux support is coming): https://sparcle.app/download/ Bolt is made by Sparcle Inc. It is not open source.
