byself sends a single prompt to many AI models at once and lines up their answers so you can compare them. Your chat history stays on your computer.
Sending a prompt to every model, browsing history, the account and payment pages, and PrivacyPlus in action.
Ask once and read every model together, decide who sees your data, and keep your whole history on your own machine.
Your prompt lands in every selected model at the same time. Raw answers appear side by side — no blending, no summary in between. Step through them one at a time, or scan them all together.
A green or red dot on every model shows its data-retention status at a glance. Flip PrivacyPlus on and the data-retaining models drop out of your selection, so they never receive the prompt at all.
Every session is stored in a database on your own machine — searchable, star-able, and exportable to PDF. byself's own servers never hold your conversations.
Bring your own key and it powers all 16 models. Admins manage seats, plans and access from one place — your organisation owns the billing and the data path end to end.

Your conversations live in a database on your own computer — not in our cloud.
Every model's data-retention status is shown before you send, so you stay in control.
