FAQ

What is a memory subject?: A distinct Graph (per-user or per-group) with read or write activity in the billing month. Every Memory in MemHQ belongs to exactly one Graph, so it is the primary billing meter — architecture-aligned.
What counts as an op?: Each call to add, search, or ask is one op. Internal background work (extraction, consolidation, embedding) runs on us and never hits your meter.
What happens if I exceed my plan?: Soft caps on paid tiers. We email at 80% of included ops, then bill overage at $0.00022 / op (Builder and Pro) or $0.00020 / op (Scale). We never block traffic unless you explicitly set a hard cap in the dashboard. Free is a hard cap.
Is MemHQ a hosted service?: Yes. MemHQ is fully managed infrastructure — we run the database, the workers, the embedders, the synthesis pipeline. You hold an API key and call three endpoints. There is nothing to install or operate.
Where does my data live?: US by default. Regional residency in EU or APAC is available at the project level on Scale and above. Customer data and embeddings stay inside the chosen region.
Do you offer annual discounts?: Yes — pay annually and get two months free on every paid tier.
