## What is Arcus?

Arcus is the AI chatbot and assistant that puts GPT, Claude, Gemini, Grok and many more frontier AI models in a single conversation. Switch models mid-chat without losing your thread, or let Auto mode pick the best one for each question. No more juggling subscriptions.

ALL THE TOP AI MODELS
- GPT-6 and GPT-5.6 from OpenAI
- Claude Fable 5.1, Opus 5.5, Sonnet 5 and Haiku from Anthropic
- Gemini from Google
- Grok from xAI
- Auto mode routes every question to the best model for the job

AI THAT DOES REAL WORK
- Live web research with citations you can check
- Ask questions about your documents: PDF, Word, Excel, PowerPoint, CSV and code files
- Summarize contracts, reports and spreadsheets with the key numbers pulled out
- Interactive charts for stocks, budgets and comparisons
- Write documents and export them to PDF in one tap
- Architecture and flow diagrams
- Execute code in a sandbox
- Send a photo and ask anything
- Memory for your preferences and projects across conversations

DESIGNED FOR PERFECTION
Fast, clean and quiet. No clutter, no dark patterns, no ads.

PRIVATE BY DEFAULT
Your conversations are never used to train models. Encrypted in transit. Delete any chat, file, memory or your whole account whenever you want.
