Magnus is the SI chief of staff for founders, startups, and small teams. It keeps your mission at the center of every day and clears the busywork out of your way. Set your mission and a handful of goals, teach it the facts about your company, and every answer comes back grounded in your business and pointed at what you're actually trying to achieve. GOALS AND MISSION AT THE CORE Define a north-star mission and a short list of goals. Magnus keeps them in view on every turn, tracks what's active and what's done, and proactively suggests the next move that pushes them forward. BUSYWORK, DONE IN SECONDS Ask in plain language and get the finished thing back - a document, a list, a spreadsheet - exported straight to PDF, Word, Excel, CSV, or Markdown. Pre-filled templates for invoices, proposals, contracts, offer letters, and newsletters use your company details automatically. MEMORY THAT KEEPS ANSWERS ACCURATE Feed Magnus notes about your company and it reads them every time you talk. Advice stays specific, on-brand, and free of the generic filler you get from a blank-slate assistant. CONNECTS TO YOUR STACK Google (Gmail, Drive, Calendar, Docs), Slack, GitHub, Notion, Dropbox, Figma, Stripe, Shopify, PostHog, LinkedIn, X, Telegram, WordPress, YouTube, Facebook, and Instagram. Magnus reads and acts across the tools you already use. RUN YOUR INBOX AND CALENDAR ON AUTOPILOT - Inbox Zero - unread mail read, summarized, and triaged into needs-reply, FYI, and ignorable - Scheduling assistant - finds free slots and sends real calendar invites - Follow-up tracker - nudges you when a reply never came - Meeting briefs - a one-page brief on who you're meeting, before every call - Daily brief each morning, evening wrap-up each night, weekly review every Monday A WHOLE SI TEAM, NOT ONE ASSISTANT Create agents with their own names, faces, voices, and models, all sharing one company memory. @mention anyone to pull them into a chat. Run a roundtable where every agent weighs in, or set two of them debating a decision until there's a verdict. TALK TO IT, HANDS-FREE Speak instead of typing and hear clear, lifelike answers back. Magnus appears as a real-time 3D avatar that listens, talks, and lip-syncs every word - a teammate, not a text field. YOUR CHOICE OF SI MODEL Run Magnus on Claude, GPT, Grok, or hundreds of models through OpenRouter - a different one per agent if you like. Bring your own API keys, or take the plan with SI credits included and skip keys entirely. WORKS IN YOUR LANGUAGE Write or speak in any language and Magnus answers in it. The full interface is translated into 30 languages. ALSO INCLUDED Web agent that browses and fills forms with your approval, live web search with sources, charts and maps in chat, scheduled and recurring tasks, natural-language reminders, contacts hub, encrypted password vault, command palette, focus sessions, shareable conversations, streaks and achievements, and cross-device sync.
