You type a question, pick the AI models you want to compare (3 on Free/Standard, up to 5 on Premium), and aggrai sends your question to all of them in parallel. You get every model's answer side-by-side, a single rewritten "aggrai's answer" that synthesises the strongest content from each, a ranked list of final scores, and a quality score out of 10 per model judged on accuracy, completeness, calibration, clarity and insight.

Your account data and your question history are private to you. Your questions are forwarded to the AI providers you select for processing — see our Privacy Policy for the full data flow including which third-party processors are involved. We don't use your personal questions to train our own models.

Two reasons. The example questions on the landing page have their answers pre-warmed in a shared cache, so they load instantly for everyone. And if you ask exactly the same question with the same models again in the same browser tab, we show the answer you already got instead of asking the models again. To get fresh answers, reword the question, change the models or open a new tab. Your own questions are never cached for, or shown to, other users.

Often, none of them are 'right' in an absolute sense — they're trained on different data, with different objectives, by different teams. Use disagreement as a signal: the question is harder, or more opinion-based, than a single model's confident answer would suggest. Verify anything important from primary sources.

Yes. Press Share above a comparison to get a link to a saved copy of the conversation: the recipient sees your exact answers, scores and aggrai's answer without re-running anything. For a comparison, they can carry it on with whichever of its models their own plan includes; a Free viewer can't continue one that only used paid models. The link picks up new turns as you add them.

On the checkout page when you subscribe: choose Have a discount code?, type your code and apply it, and the price updates before you pay. A code may only cover some plans or billing periods. You can also add a code when you change plan, under Settings → Change plan, unless you're on a free trial, your subscription already has a discount (only one can be used at a time) or the code is for new customers only. A code for free months starts a free trial instead, and can only be used when you start a new subscription, not when you change plan.

To cancel, go to Settings and choose Cancel subscription. You keep your plan until the end of the period you've paid for and aren't charged again; the current paid period isn't refunded. If a payment has failed, cancelling ends the subscription straight away and the overdue payment isn't collected. To switch between Standard and Premium, pick the plan under Settings → Change plan. To switch between monthly and annual billing, use the switch next to your current plan there; that also moves your billing date to the day you switch. You'll see exactly what will be charged or credited, and once you confirm, the change applies straight away: anything due is charged immediately, and unused time on your old plan becomes account credit that comes off future bills. Any credit left when your plan ends is refunded to the payment method you paid with; refunds usually take 5 to 10 working days to show. Deleting your account ends your plan straight away: account credit is refunded, but the current paid period isn't. For anything else, contact us.
