When you attach a PDF in a conversation that can act on your behalf, the file goes in full along with the text read on the device — so it can be saved or attached wherever you ask, without needing to send it again…
The file is stored in a private folder, only your account can use it, the limit is 8 MB per PDF and it is deleted after 7 days without use. In other conversations nothing changes: the PDF is still read on the device itself…
When you reply to a notification that arrived in your list, the new conversation stays linked to the source notification. Your reply reaches whoever sent the notification even when two notifications have the same text.
Sign in or create your account with Google or Facebook on all devices. On iPhone and iPad, also with Apple.
Google and Facebook login opens in the system's secure window, and the app only receives your Cortex account — no provider password passes through it.
If a Cortex account already exists with the same email, the app asks you to confirm it is yours (current password or a code sent by email) before linking the new login. Nothing is merged without this confirmation.
Fixed the profile screen appearance when logging out and back in: on mobile it could open outside the theme, with a dark background, underlined text, and error warnings in the footer.

When you sign out or sign in to another account on the same device, the previous account's connections, folders, and projects leave the screen and do not carry over to the new account.
Passwords and connection keys saved on the device are kept separate per account and come back when you sign in again.
Device theme, language, and other preferences remain unchanged.
After buying credits or a plan, the app celebrates with you: a confetti notification shows what was added to your account (e.g., "+R$ 50.00 in credits" or "Pro plan active until 31/10") and a button…
With "reduce motion" enabled on the device, the notification appears without animation.
New look, same as the apps: the writing bar got a + button that brings together attachments, how much Cortex should think, and your skills and connections, and the model and effort selection is next to the button for…
Cortex AI Chat on Google Play, with credits and plans purchased through the store itself; device identifier only goes to the Cortex server and responses can be flagged as offensive.
