Build your own apps with AI

From simple databases to powerful custom applications. No coding required.

Describe the app you need. The AI builder creates its libraries and screens and checks that everything works. The app runs right inside Memento, so you use it at once, offline and without AI.

How it works

Talk to the builder like you would to a developer on your team.

1
Describe it

Tell the builder what the app should do in plain words, or start from a suggestion. When something is unclear, it asks, with options to tap.

2
The AI builds it

It creates the libraries the app needs or connects yours, writes the screens, runs the app to check that it loads, saves and shows the right data, and fixes the errors it finds.

3
Use it, improve it

Try the app right away: no hosting, no deploy, nothing to install. Say what to change, "Make the buttons bigger", and see it at once. Every request is saved as a version you can undo.

What you can build

Each of these apps started as one sentence.

The Memento difference

Your app's data lives in your database

Apps save ordinary entries in your Memento libraries, so nothing is locked inside the app.

  • Search, filter, chart and export app data like any other entries.
  • Cloud libraries sync to Memento on iOS, Windows, Mac and Linux.
  • Connect the libraries you already have, or let the builder create new ones.
  • Delete or rebuild an app: its entries stay.

Made for your phone

Apps use what your phone can do, and keep working where there is no signal.

Works offline

No internet and no AI needed to use an app.

Camera & files

Add photos from the camera and files from the phone to entries.

Barcode & QR scanner

Scan codes with Memento's scanner; the app gets only the code.

Voice notes

Record sound into an entry while the app is on screen.

CSV & PDF export

Save reports and spreadsheets to your phone.

Home-screen shortcut

Open your app like any other app on the phone.

Full screen & kiosk

Hide the bars for a game or a tablet on the wall.

Web services

Fetch exchange rates, weather or parcel status from hosts you allow.

From forms to games

Pick a framework when you create an app. The builder connects the add-ons it needs.

Frameworks
  • Ionic · mobile screens: lists, forms, tabs and cards
  • PrimeVue Aura · data-heavy screens: forms, tables, dialogs
  • PrimeVue Material · the same, with the Material look
  • Plain HTML · simple pages with nothing extra
  • Canvas game · games drawn on a canvas, with touch input
  • Phaser · 2D games with sprites, physics and sound
  • 3D scene · interactive 3D scenes and model viewers

Add-ons are included in Memento and work offline. Map tiles load from the hosts you allow.

Multi-user out of the box

  • Upload an app to Memento Cloud, and your team works in it together, with the same data synced to every device.
  • Give users or groups access and choose who can read, add, edit or delete entries in each library.
  • Accounts, permissions and sync come from Memento: there is no backend or sign-in screen to build.
  • Make it public for all Memento users and send the link. No web hosting or app store needed.
  • Export it to a file with its libraries' structure, or copy it as a starting point.

Safe by design

  • An app reaches only the libraries you connect, with the access you allow.
  • It goes online only to the hosts you approve.
  • API keys are encrypted on your device; the builder and Memento Cloud never see them.
  • Every change is a version you can restore, and the code is open to read and edit.

Unlimited apps on every plan

Building and changing an app uses the AI credits included in your plan, or your own OpenAI-compatible API key. Using apps is free.

Questions about apps

No. You describe the app in plain words, and the AI builder writes it, runs it to check that it works and fixes the errors it finds. Tell it what to change and it updates the app; every request is saved as a version you can undo. If you do code, you can read and edit the app's files.
No. An app runs right inside Memento on your phone: there is nothing to host, deploy or install, and no server to set up or pay for. It is ready the moment the builder finishes, and every change shows up at once. To share it, upload it to Memento Cloud and give people access.
No. Using an app needs no AI and no internet once its libraries are on the device, unless the app itself works with a web service. AI is used only while you build and change the app.
In your Memento libraries. An app saves ordinary entries that you can search, chart, export and sync like any others, and they stay when the app is deleted.
Apps are built and run on Android. The data they save is ordinary Memento data: in cloud libraries it syncs to Memento on iOS, Windows, Mac and Linux.
Apps are unlimited on every plan. Building and changing an app uses the AI credits included in your plan, or your own OpenAI-compatible API key. Using an app costs nothing.
Yes, apps are multi-user out of the box. Upload the app to Memento Cloud and give users or groups access: everyone works with the same libraries, each with the read, add, edit and delete permissions you choose, and changes sync between devices. Accounts and sign-in come from Memento, so there is nothing to build for that. You can also make an app public for all Memento users, or export it to a file with the structure of its libraries.
An app reaches only the libraries you connect, with the access you allow, and only the internet hosts you approve. API keys are encrypted on your device and never seen by the builder or Memento Cloud. While you build an app, what the builder reads is sent to the AI provider of the model you chose, as in any AI assistant chat.
