chatGPT Claude Gemini Grok Perplexity AI opinion

One question — every perspective

Send any prompt to all models at once and get every answer in one panel, plus a short combined summary. When the answer matters, one voice isn't enough.

Translations — see how each model renders nuance, tone, and idiom differently
Medical results — cross-check interpretations before a doctor's visit
Decisions — get a range of arguments before committing to a choice
Contracts & documents — spot what one model missed
Creative work — collect five directions instead of one

Fusion and Ultra — many AIs on one task

Fusion runs several AIs in parallel on a deep dive, cross-checks the facts and merges everything into one coherent document. Ultra splits a big task into subtasks, works each with its own model in parallel, then assembles a single thorough answer.

Memory Tree and Digital Brain

The Memory Tree automatically links facts, people, events and ideas from all your conversations into a personal knowledge graph. The Digital Brain feeds that memory into every model — so any AI answers already knowing your context.

Pay only for what you use

No subscription. Top up any amount and spend it strictly as you go — billed to the cent for every request. For most people that's far cheaper than paying for several AI subscriptions at once.

More than text

Generate images and video, hear replies in a natural voice, dictate by voice, or hold a live voice conversation in real time — all in one place, all pay-as-you-go.
