Model

Which model Quanta opens with.

Speed

Where the speed meter starts. It sets how hard the model works and how much of the conversation it keeps in view.

Chat

Start on the welcome screen

On, Quanta opens on the welcome screen with a new conversation every time you launch it. Off, it takes you straight back into your last conversation, even after closing the app.

Press Enter to send

Off sends with Ctrl+Enter, so Enter makes a new line.

Show usage meters

The 5-hour and weekly bars beneath the message box.

Ask before deleting

Deleting a conversation asks for a second press to confirm. Deleted conversations cannot be recovered.

Voice

Read replies aloud

Speak each answer as it arrives.

Voice

Used when Quanta reads replies aloud. Auto picks the best voice on your device.

Memory

Remember useful details

Say “remember …” and Quanta keeps a note across conversations. Everything is stored only on this device, never synced to your account — it is yours, and QuantaCore can never read it.

Manage memory

See, edit, delete — or take it with you. Export and import your memory as a file you own.
