AI chat, without the juggling
GPT, Claude, Gemini and Grok in a single conversation. Switch models mid-chat without losing the thread, or let Auto pick the right one.
Product
Arcus does the work behind the answer: it researches, reads your files, runs code and hands you something you can use.
Net worth breakdowns, stock trends, architecture flows and polished reports, built live and exportable to PDF in one tap.
Answers grounded in current sources, with citations you can open and check.
PDF, Word, PowerPoint, Excel, images and code. Ask for the key terms, numbers or clauses.
Briefs, plans and emails formatted properly, not pasted as a wall of text.
Model-written code runs in isolation and returns real output.
Preferences and projects carry across conversations.
Send a photo, a chart or a screenshot and ask anything.
Pricing
Each lab sells its own plan, and each one forgets what you told the others. Arcus Unlimited covers all of them.

No clutter, no dark patterns, no ads. Built for people who think for a living.
Your conversations are not used to train models.
Every request between the app and our servers is encrypted.
