Honest notes

No paid tier exists yet. Both options above are free while SyntheticMem is in preview. If paid plans arrive, preview users will be told before anything changes.
Demo keys are rate-limited and ephemeral — they share a capped pool so the public demo stays available, and their memories are deleted after 24 hours.
Registered memory is permanent unless you set a ttl_hours on a memory or delete it yourself.
