2026-06-26Personal finances expands to Plus users and AndroidUS Plus users can access personal finances on web and iOS; US Pro/Plus users now have Android support; connect accounts via Plaid to view a spending/bills/net-worth/investments dashboard and ask grounded questions—cannot move money, trade, or act as a financial adviser.

2026-06-22Large-paste-to-attachment for Free/Go usersNow available to Free/Go users: pasting more than 10,000 characters into the input box automatically converts it to an attachment (paid users previously had a 5,000-character threshold; threshold is now 10,000 characters for everyone); click “Show in text field” to convert back; keeps the context window cleaner.
