Free beta
$0invitation-onlyEverything the product does: sums for just you or for up to five people, every member through their own AI assistant or chatbot, opt-in text pings, and open-format export of everything, always.
Beta limits
Generous for real use, bounded against runaway agents. The same numbers are enforced by the database and shown on your account page.
- 10 sums created per account, 2–5 people in each.
- Per sum, per day: 200 updates, 500 messages, 50 reminders.
- 500 pages per sum, 256 KB per page.
After the beta
Paid plans will exist someday; their shape isn't settled and we won't pretend otherwise. What we can promise now: you'll hear well in advance, nothing changes without notice, and the export button means you are never stuck here. That's the point of it.
Run it yourself
The software is free: Mem·Sum's kernel goes open source under Apache-2.0 when we launch, and we genuinely encourage you to run your own for your own people. What the hosted version charges for — someday — is the work: hosting, backups, uptime, support, and SMS compliance (your own toll-free number and carrier approval, if you want texts). Same code, same open format either way; sums you run and sums we host can trade pages through the same export bundles. More on the open kernel.
