Compendium is a company brain for teams working with AI agents. With compendium, all your agents share one memory, so knowledge, decisions, and context are available to everyone, everywhere, instantaneously. Compendium allows you to work in shared sessions where you and your teammates' agents build on the same context instead of siloed threads, get summaries of what changed while you were away (without digging), and have a live view of what your teammates and their agents are building right now.
Hi Product Hunt 👋 I'm Jonathan, co-founder of Cerenovus (YC S26). A few months ago, my friends and I were building the product we wanted to use: a personal “second brain” to collect and organize the information we collected across our busy lives. Then, after talking to a few companies, we figured out that organizing information across an entire business was a way bigger problem that we now had the solution for.
Compendium is the version of that solution that we’ve built specifically for startups, especially AI-native tokenmaxxers like ourselves. (:D)
If you’ve ever built a feature only to find that your teammate has built an identical one, or made an architectural decision only to have a teammate make a conflicting one, this product is for you. Cerenovus doesn’t just help with dev though —¹ it also incorporates information from email, slack and basically everything else, in order to have all your team’s information in one place, linked together and easily navigable by both humans and agents, so there’s something for your GTM team to be happy with too.
¹ (AI will not steal my em dashes)
Tl; dr - we got:
Shared context: everything in one place and always up to date - a single source of truth for your team and your agents
Multiplayer sessions: jump into the same session with a teammate and drive one Claude together, like a Google Doc for AI. (didn’t mention this above, but it’s really cool)
Always in the loop: a live view of what every teammate and agent is working on right now (opt-in, obviously), plus summaries of what changed while you were away.
We're two months old and we know it. We'd rather hear what's broken than what's nice. I'll be in the comments all day answering everything. We ship bug fixes 24/7.
