What sync adds

The same memory on every computer

Remember something on your laptop and your desktop recalls it. Each computer you add joins your plan at the same per-device rate.

Backup you do not manage

Managed backup comes with the plan, so a lost or broken computer is a restore, not a loss.

Encrypted before it leaves

Synced data is encrypted on your computer before upload. How the encryption works.

Never used for training

Not on any tier, in any form, including anonymised. What we hold, per mode.

Cancel any time

Sync keeps working to the end of the period you paid for, then your copy is read-only for 30 days so you can restore or export it. Memories on your computers are never touched.

Free stays free

Every computer you install it on, no memory cap, no account. Sync keeps them in step, and nothing you already have gets taken away.

What it costs in practice

Two computers and a 2 GB brain: $12 a month billed yearly ($144 a year), plus about 10 cents a month for storage. Paying monthly it is $16 plus the same 10 cents. Yearly saves $24 per device each year. Sales tax or VAT is added where it applies.

Storage
$0.05 /GB/mo

One rate for everything we store on your behalf: managed backup snapshots, synced data, and Teams shared partitions. Metered on what is actually stored at the end of each month, with no minimum, no included allowance to keep track of, and no different rate per tier. A typical brain is a few hundred megabytes to a few gigabytes, so for most people this is cents, not dollars. Storage on your own computer is never metered.

Is free a trial?

No. It's the complete product for one person on their own machines, with no time limit and no memory cap. The paid tiers add other people's computers, not features.

Is my data used for training?

No, on any tier, in any form, including anonymised. What we do hold, per mode.

How do I start?

Install ModelBrain, then open modelbrain.net/account (or the Account window in the app), sign in with your email, and choose yearly or monthly. Sign in with the same email on your other computer to add it.

What if I cancel?

Your memories keep working, because they never depended on us. Sync and backup keep working until the end of the period you paid for, with no refund for the rest of it. Then your synced copy stays read-only for 30 days so you can restore or export it, and is deleted after that. How cancelling works.
