What Dex Sees

Every time you send a message, Dex automatically attaches browser context:

• Active tab: full page content converted to markdown (cleaner simpler text to read and process).
• Open tabs: titles, URLs, and tab group info for all open tabs.
• Recently viewed tabs: removes duplicated lists of recent pages.
• Browsing history: pages with AI-generated summaries.
• Recent actions: your last 5 interactions (clicks, typing, navigation).
• Highlighted text: any text you've selected on the page.

Interaction Tracking

Dex tracks browser interactions in the background, batched and sent every 30 minutes:

• Page loads: summarized content of the pages visited.
• Clicks: element descriptors (tag, text, role, URL) for interactive elements.
• Text input: text entered onto pages (search bars, forms, etc.).
• Copy/paste: text-based clipboard operations.
• Tab switches: switching between tabs and keeping track of the previous/current tab info.

These interactions feed the pipeline and provide recent-action context at chat time to help Dex understand your workflow.

Page Content

Dex extracts content based on page type:

• Webpages: HTML to clean markdown with URL-specific enrichment.
• PDFs: text pulled from PDF files.
• Google Docs: live content from your docs.
• Google Sheets: live data from your spreadsheets.

Privacy

• Domain blocklist: exclude specific sites from all context collection. Manage your blocklist in Settings.
• Auto-skip: auth pages, payment forms, and medical sites are automatically excluded.
• Password detection: content extraction blocked on pages with password fields.
• System pages: chrome:// URLs are always excluded.
• Global toggle: disable all browser context collection in Settings.
