Every tier gets the full product — memory, skills, tools, agents, roles. Only recalls are metered. Build the habit, grow into the limits.

Your AI should never hesitate to write memories — that's how the brain grows. So storing, loading, and logging sessions are not rate-limited. Only recalls count against your quota, because those are the operations that reach into stored knowledge at query time.
Create as many brains as your tier allows — the memory, storage, and recall quotas pool across all of them. Split by project, team, or domain without worrying about hitting a per-brain ceiling.
Five seats start at $195/mo and each seat equals one member. Add teammates by adding seats at $39 each — grow to 50, 500, or 5,000 members with no hard cap. Every seat also multiplies brains, memories, recalls, storage, agents, tools, and connectors linearly.
You'll see a clear upgrade prompt in your AI client. Storage and hydration still work — you'll just lose the ability to query memories until next month or until you upgrade. We do not delete any of your data.
Because memory is only useful if your AI stores everything. Rate-limiting the write path breaks the habit and degrades the product. Recalls are the actual query cost — every search hits the vector store and triggers reranking. Metering there means the free tier can still build the habit, and paid tiers unlock scaled retrieval.
Yes. Upgrades take effect immediately — your new limits apply to the current billing period. Downgrades apply at the start of your next billing period so you don't lose access mid-month. Your data is never touched during tier changes.
Agents and tools themselves are included in Pro+ — there's no per-agent or per-tool fee. The recalls and API calls those agents perform count against your account's recall and API limits, same as if you made them yourself. Storage for tool code is negligible and included.
Pro is strictly single-user — one member, no team sharing. It's designed for one person running multiple AI clients (Claude, Cursor, ChatGPT) who wants persistent memory shared across all of them. The moment you want to collaborate with a teammate, upgrade to Business: that's where team brains, per-seat attribution, cross-brain recall, and org analytics live.
As your brain grows, Zombie Brains can train a reranker tuned to your language — which topics you care about, which memories matter to your workflow. At 1,000 stored memories (Business tier), we train a custom reranker on your brain's implicit feedback. At 10,000 memories (Enterprise tier), we additionally train a company-specific embedding model so semantic search literally learns your vocabulary. This isn't just infrastructure — it's your brain getting smarter about you automatically.
Yes — annual plans get 2 months free (17% off). Visible in the billing portal when you start a paid plan.
Business is self-serve with team features. Enterprise is negotiated — we'll discuss your scale, compliance requirements (SOC 2, DPA, custom data residency), SAML/SCIM integration, and whether you need dedicated infrastructure. Most enterprises start on Business and upgrade when they hit 100+ seats or need SSO.
