Cabinet is a free, open-source knowledge base and 'startup operating system' that stores everything as markdown files on disk — no database, no vendor lock-in, no subscription. It scaffolds a full AI team (CEO agent, Editor agent, Marketer agent, etc.) around your company context in five minutes, with cron-based automation for recurring tasks like competitor monitoring and newsletter drafts. The 'everything is markdown on git' philosophy makes it genuinely portable. You can spin up a web terminal inside a folder, link a git repo for source code, run Kanban boards, and embed HTML apps — all without leaving the interface. AI agents have access to your entire knowledge base, not just a retrieval snippet. For solo founders and small teams who want to avoid SaaS subscriptions for wikis, project management, and AI tooling, Cabinet bundles everything into a single `npx create-cabinet my-startup` command. It's one of the rare tools where 'free and open-source' isn't a stripped-down version of something paid.

Spectrum, from Photon, launched on Product Hunt today with 105 upvotes and a simple but sharp premise: your users don't want to learn a new AI interface—they want AI to show up in Slack, Teams, email, and every other tool they already use. Spectrum is an agent deployment layer that routes your AI agents to wherever your users are, with no per-integration custom dev work. The core product is an abstraction layer that handles the connector plumbing: authenticate once, and your agent can receive messages and send responses across all connected channels. Built-in conversation management means agents maintain context across channels—a user can start a request in Slack, continue it in Teams, and finish in email without losing thread. The platform also handles rate limiting, authentication, and error handling for each channel. For teams building internal AI tools or customer-facing AI assistants, this solves real integration pain. Building a Slack bot, Teams integration, email handler, and web widget separately takes weeks per channel. Spectrum reduces that to a single agent definition deployed everywhere. The question is pricing and lock-in: if Photon becomes the integration layer, they sit in a strategically critical position.
Reviewer scorecard
“Git-backed markdown with a built-in web terminal and AI agents that can actually schedule tasks — this is what Notion should have been for developer-founders. The `npx create-cabinet` scaffold makes setup genuinely fast. The lack of a hosted SaaS tier means you own your data forever.”
“I've built the same Slack bot four times in different frameworks and it's never not painful. A write-once, deploy-everywhere agent layer is exactly what I'd pay for. The cross-channel context persistence alone is worth evaluating.”
“Self-hosting a knowledge base plus AI agents plus task automation is three different categories of ops burden for a founder whose main job is building product. The AI agent 'budget controls' mention suggests costs can spike, and there's no mention of how model API credentials are secured. For a solo founder, Notion + one AI tool is genuinely less work.”
“Every integration platform promises this—Zapier, Make, n8n, Workato all have 'write once, run everywhere' messaging. The enterprise channels (Teams, Slack) have quirky APIs that break constantly with updates. Spectrum is taking on significant maintenance burden that will eventually get priced into your bill.”
“The 'startup OS' framing is exactly right — as AI agents become capable of autonomously running business functions, the knowledge base IS the company's operating layer. Cabinet is an early prototype of what every small business will run in five years: a context-aware, agent-staffed operational core.”
“The interface layer for AI agents is becoming the new battleground. Whoever controls where agents appear controls where work gets done. Spectrum is building valuable real estate in that layer.”
“Scheduled AI drafts for newsletters while I sleep, competitor monitoring that writes its own briefs, a Kanban linked to my git repo — all free and local. For a content-first founder this is almost too good to be real. The WYSIWYG editor with markdown toggle is a small thing that matters a lot day-to-day.”
“For content and community teams, having one AI agent that shows up in Discord, Slack, and email simultaneously without separate setups is a genuine time saver. Spectrum removes the 'which channel do we actually deploy to?' paralysis.”
