Description (4000 char max) Archius is an AI assistant built for one thing: getting you a real answer, fast. WHAT MAKES ARCHIUS DIFFERENT - Direct. No "Great question!", no filler, no walls of preamble. You get the answer and you move on. - Honest. When Archius doesn't know something, it says so. It won't make up facts, sources, or citations to sound confident. - Actionable. Ask for an email and you get a sendable card — editable in place, send through your real mail app. Ask for a meeting and you get a calendar event ready to add. Not a wall of text to copy out. - Built for answers, not entertainment. No emoji-heavy enthusiasm, no rambling explanations. For people who want the answer and to move on with their day. PRO FEATURES ($12.99/MONTH) - Web search with cited sources. Toggle the search mode and Archius looks up current information, then answers with the URLs it used. - Deep think mode. Switch to the advanced reasoning model for hard problems — math, planning, multi-step logic. - Image understanding. Attach a screenshot, photo, or diagram and ask about it. - 500 fast messages a day, 50 advanced messages, 25 image-aware messages. FREE TIER - Full access to the actionable email and calendar drafting features. PRIVACY - Your messages are sent to AI providers (DeepSeek and Google) to generate responses, then forgotten. Archius doesn't train models on your data and never sells it. Full policy at https://archius.app/privacy. - Local-first chat history. Conversations live on your device, not on our servers. - Sign in with Apple, Google, or email. Delete your account any time from Settings. Made for people who'd rather get answers than be entertained. — Terms of Use: https://archius.app/terms Privacy Policy: https://archius.app/privacy
