About Almanac
Summary
Almanac builds an AI assistant that operates across a company's tools, conversations, and accounts to complete tasks and maintain a living knowledge base. It connects to Gmail, Calendar, GitHub, Attio, meeting notes, and AI conversations, then compiles everything into a self-updating wiki that tracks projects, decisions, customers, and next steps. Workers message it through Slack or iMessage instead of manually chasing context across apps or keeping documentation up to date themselves.
Business model
Paid plans with a pricing page; specific tiers not detailed in sources.
Go-to-market
Almanac targets individuals and small teams in B2B companies who manage projects across multiple tools, with a self-serve entry point through a Mac desktop app download.

The AI that knows your company
Almanac is Hermes with a company brain. You message it in Slack or iMessage; it knows what is happening across your company and can use your accounts to get real tasks done for you. It has a full computer, browser and terminal. It takes your Gmail, Calendar, Attio, GitHub, AI convos, docs and meeting notes and compiles them into a Wiki that keeps itself up to date. It keeps a current understanding of what you’re building, who your customers are, what was decided, and what still needs to happen. It can use websites, run code, create files and take actions across your accounts. If it reaches a login, payment or decision it shouldn’t make alone, it pings you or hands you the live browser.
