Almanac: An AI Agent with a Self-Updating Company Wiki

Almanac (YC S26) is an always-on AI agent that maintains a self-updating wiki of your company's knowledge by connecting to your existing tools (Gmail, Slack, Google Calendar, PostHog, etc.). It runs on its own computer, so it can act proactively and follow up on tasks over days, not just single sessions.

How It Works

Almanac compiles information from your connected sources into two wikis: a personal wiki (understanding you, your preferences, and your life) and a company wiki (what the company is, what you're working on, roadmap, blockers). This pre-compiled knowledge layer allows the agent to “just know you.”

Key features:

• One-click connections to Gmail, Calendar, Granola, PostHog, and more. Personal accounts are only accessible by you; shared accounts are accessible by everyone.
• Wiki entries link to their source, so you can verify every claim. If the wiki is wrong, you can correct it and Almanac learns from the correction.
• Proactive agent: a background worker suggests tasks it can complete, e.g., “I already prepared a draft of your fundraising pitch deck, want to take a look?”
• Long-horizon tasks: Almanac keeps context on ongoing projects, so it can pick up a task days later, e.g., sending a follow-up email after noticing a reply.
• Own computer: Almanac uses its own browser, files, and logins, even for tools without an integration.

Privacy and Security

Almanac only accesses accounts you explicitly connect. OAuth credentials are held by the connection provider, not in Almanac's database. Only the wiki and the source behind citations (e.g., an email used as a citation may be retained as Markdown) are stored.

Who It's For

Teams that want an AI agent that actually gets tasks done across their existing tools, without having to re-explain context every time.
