I teach piano. I need one place for my students, their lessons each week, and who has paid.
Here is the plan. Tell me if anything should be different.
- Your students, with their level and what they are playing
- This week's lessons, day by day
- Who has paid, and who has not
- A total for the week and the month
Trying it out to make sure it works…
Ready. It is on your shelf.

Made from one sentence
Every one of these began as a few words typed into Synti. No templates, no settings, no code.
“A plain notebook that keeps everything on my own computer.”
Notes
“A place for the songs I bought, with their sleeve art.”
Soundshelf
“A calculator with big buttons that remembers what I added up.”
Calculator
“A file browser that looks and feels like the Mac's own.”
Finder
“A way to see and add Mac tools without typing commands.”

Three steps, and you have it
A list of my plants, and which ones need water today

In your own words, in any language. Add a picture or a file if it helps explain.

- How often each needs water
- Today's list
- Trying it out
Watch it being made
The plan is written out first, then the app is made and tried out. You can say “also make it…” at any moment.
- Notes
- Soundshelf
- Calculator
- Plants
Open it
It lands on your shelf as an app of its own. Want something changed? Just say so.
It is yours. Really yours.
Most apps you use live on someone else's computer and stop the day that company does. Apps made with Synti do not.
Your data stays on your Mac
What you keep in an app is a file on your own computer. Nothing you ask for and nothing you store is ever sent to us.
It works without the internet
On a plane, in the country, with the Wi-Fi down - the app opens and everything in it is there.
It keeps working, whatever happens to us
No account to use it, nothing to renew. If Synti disappeared tomorrow, every app you made would still open.
Every app has Claude inside
Ask an app to do things for you, in plain words. It can do anything its buttons can - and several things at once. Before it deletes or replaces anything, it asks you first.

Share what you made
One click puts your app in the Synti App Store, with a page AI writes for you. Anyone can find it and get their own copy - and nothing you kept in it goes along, unless you choose.
- NotesA plain notebook that keeps everything on my own computer.
- SoundshelfA place for the songs I bought, with their sleeve art.
- CalculatorA calculator with big buttons that remembers what I added up.
- FinderA file browser that looks and feels like the Mac's own.
Free to make. Always.
Making apps, changing them and using them never costs anything. The AI is your own Claude plan - we never charge you for it, and never sell it to you.
Questions
Do I need to know anything about programming?
No. You describe what you need in your own words, and that is all. Synti never shows you code unless you go looking for it.
What do I need to use it?
A Mac and a Claude account. Synti uses your own Claude plan to make your apps, so there is no second AI subscription to pay for. A paid Claude plan works best: making one app is a real piece of work.
Where are my things kept?
In a folder on your own computer, one per app. Nothing you type into an app, and nothing you ask Synti to make, is ever sent to us.
What happens to my apps if Synti shuts down?
They keep working, exactly as they do today. They need nothing from us to open: no account, no licence check, no data in the cloud.
What if the app is not quite right?
Say what is wrong and it is changed. The new version is tried out before it replaces the old one, and your data is never touched by a change.
Can I share what I make?
Yes. Publish it to the Synti App Store and anyone can get their own copy. What you kept in it stays yours, unless you choose to include it.
What will you make first?
A tracker for your garden. A recipe box. A list of who owes you what. The small app nobody else would ever make for you.
