Bonsai Capture is built to keep your AI conversations local. The extension stores captures on your device, and this landing page uses privacy-preserving Cloudflare Web Analytics plus the information you choose to submit through the waitlist form.
At a glance
Website
The Bonsai Capture landing page is a static marketing site. It uses Cloudflare Web Analytics to understand aggregate traffic and referral trends. It does not use advertising pixels or remarketing tags. If you submit the waitlist/contact form, the name, email, and message you provide are transmitted to Formspree so the request can be delivered.
If you do not submit the form, the site does not collect personal information.
Extension
The extension reads the content of supported AI chat pages so it can capture conversation text, structure, code blocks, artifacts, inline images, and generated media that you intentionally open in those tabs.
Captures are stored in chrome.storage.local on your device and are not uploaded to any remote service by default.
Permissions
activeTab, scripting, sidePanel
Used to open the side panel and inject capture logic only when you actively use the extension on supported pages.
storage, unlimitedStorage
Stores captures locally, including conversation records and large embedded media data URLs.
declarativeNetRequest
Creates temporary per-request header rules for provider-hosted media fetches that require Origin and Referer headers. Rules are removed immediately after each fetch.
clipboardRead
Fallback for capturing Claude artifact source when the native copy flow is the only reliable extraction path. It is used only on supported capture flows.
Host access
Content scripts run only on ChatGPT, Claude, Gemini, and Grok pages so the extension can read the conversation DOM. Additional host permissions are limited to provider CDNs that host generated media or sandboxed research frames that the capture flow must access.
Retention
The extension keeps a rolling window of the most recent 50 captures. Older captures are dropped automatically. You can also clear the data by removing extension storage or uninstalling the extension.
The landing page does not retain waitlist submissions itself; Formspree handles form delivery for submitted entries.
