Your database, everywhere.
Still yours.

Exemem is the cloud companion to LastDB — backup, multi-device sync, and delivery for the database your whole tool stack is built on. Exemem moves your data; it never mines it.

Request Early Access See What It Does

Your database, on every machine

Encrypted snapshots of your LastDB, restorable anywhere. New Mac? Install, connect, and your memory, board, and apps are back where you left them.

A rail, not a platform

Exemem is transport and storage only. It carries opaque, addressed payloads between LastDBs — it does not compute on, index, or monetize what's inside.

Deliver slices of your database

Hand a curated slice — a digest, a dataset, a board rollup — to a person or an app. They get a usable piece of your stack; you keep the source.

What the rail is for

Your LastDB runs at home, free, no account. Exemem is what you add when your database needs to travel — between your machines, to your people, through your apps.

Multi-Device

“Same brain on both Macs.”

Your desktop and your laptop share one database. Notes filed on one machine are queryable on the other — memory, board, and app data stay in step.

Disaster Recovery

“My laptop died on Tuesday.”

Encrypted snapshots flow up as you work. On a new machine: install LastDB, connect your account, and years of accumulated context come back.

Deliver to People

“Send the project digest to my cofounder.”

Address a slice of your database to someone. Exemem routes it; their LastDB receives it as usable records — not a PDF attachment that goes stale on arrival.

Apps on the Rail

“My tool ships results to its users.”

Tools built on LastDB use Exemem as their delivery rail — rollups, reports, and datasets addressed straight into their users' databases. No per-app backend to run.

How it works

The database stays home. The cloud is a rail.

1

Connect

LastDB runs locally with no account. When you want cloud, lastdb connect joins your node to Exemem — invite-gated while we're pre-launch.

2

Back up & sync

Encrypted snapshots flow up; your other machines pull them down. Storage is usage-metered — a free tier to start, paid plans as your database grows.

3

Deliver

Address a slice of your database to a person or an app. Exemem routes the opaque payload; the recipient's LastDB receives it on their terms.

Two parts. One owner.

Your LastDB is where everything lives and computes. Exemem is the rail that moves it. The trust model is that simple.

Your LastDB Exemem
What The database + every tool you build on it The cloud rail: backup, sync, delivery
Runs One process on your machine Managed cloud infrastructure
Computes Search, transforms, your apps Nothing on your data — transport-only by design
Sees Everything — it's yours Your account, usage meters, opaque payloads
Data Owner-controlled, deletable Encrypted snapshots + addressed slices
Account None needed — local is free forever Free tier; paid plans metered on storage
Purpose Own — the data and the whole tool stack Move — between machines, people, and apps
