twin memory

Priced by what you write and what you search.

Two meters: events written and retrievals searched. Reads by address, history and erasure are never metered, and every plan gets the same memory.

An event is one item written

A message counts 1 whatever its length, up to 64 KB. A document counts 1 for each 2,000 characters, so a 9,000-character contract is 5 events.

A retrieval is one search. Everything that reads by address, and every erasure, is free.

Degrade, don't drop

Going over a limit never loses what your users said. Writes still land and stay searchable; only the paid reading waits, and catches up when the month turns or the plan changes.

A missed write cannot be recovered later. A delayed read can.

Questions

What is an event?
One item written. A message, note or activity counts 1 whatever its length, up to 64 KB. A document counts 1 for each 2,000 characters, because it is read whole.
Does a long message cost more?
No. A message counts 1 whether it is ten words or ten pages, up to 64 KB. Only documents are counted by length.
What is never metered?
Reads by address (read, ls, grep, around, latest, overview), history, versions, lineage, status, forget, correct and export. Erasing your users' data is never something you pay for.
What happens at the limit?
Nothing is dropped. Writes still land and stay searchable; reading them into dated facts waits. Past the retrieval limit, search answers with the unfiltered ranking, which costs nothing to compute.
Is retrieval quality different by plan?
No. Every plan runs the same engine with the same model calls. Plans differ by volume, operations and governance, never by how well memory answers.
Can I pay today?
Not yet. Checkout is not live, so every account starts on Free and no card is taken. Paid plans open with checkout.
How does this compare with Mem0?
Mem0's Starter and Pro carry the same quotas, 50,000 adds and 5,000 retrievals, and 500,000 and 50,000, at $19 and $249 a month (mem0.ai/pricing, read 2026-10-09).
Is there a cap on spend?
Yes. Each organisation has a daily cap on what memory may spend on model calls. Past it, nothing is refused: reading waits, and search answers with the free ranking.
