How many sessions do I have left?
The client signs in and sees their session pack and today’s workout. The trainer sees whose pack is about to run out, and only the trainer can change the count.
For businesses whose clients still ask you what they should be able to look up themselves
An AI web app builder that needs one sentence, not a developer quote. Your clients get their own login.
Say who signs in and what they do. The AI builds the app: a client portal, a price calculator, an inventory list, work orders, a session tracker. The platform owns sign-in and permissions, and before anything goes live, the system tries to break into your app. Everyone who signs up becomes a contact in your CRM.

Gammatica's AI web app builder turns one sentence into a login app at its own address, such as a client portal or price calculator, with platform-owned sign-in, 30+ security checks before publishing and sign-ups in your CRM.
Four typed requests, four login apps: a session package tracker, a cleaning schedule, HVAC work orders, and a client portal.
A trainer gets a session package tracker and workout plans from one sentence, clients check off workouts on their phones, and packages running low show up flagged.
A cleaning company gets a schedule, an on-site checklist with photos, and client records, and each client’s page shows when the cleaning is done.
- A login app from one sentence: client portal, calculator, inventory, work orders
- Its own address to send people to: yourapp.gammatica.ai, separate from your website
- Sign-in and permissions come from the platform; the AI writes no security code
- 30+ attack checks before every publish, and you can’t switch them off
- Everyone who signs up and verifies their email becomes a CRM contact
In numbers
- and you get the plan: who signs in, what it stores, who sees what
- 1 sentence
- attack checks before every publish, and you can’t turn them off
- 30+
- while it runs: a live app makes no AI calls

Ready samples
What a finished app looks like.
A personal trainer, a cleaning company, an AC service. Sign-in, lists, schedules and sample data, all working.
Personal trainer app: clients and passes (Hungarian sample) Cleaning company app: public home page (Hungarian sample) AC service app: maintenance due (Hungarian sample) Personal trainer app: the client’s workout today (Hungarian sample) Cleaning company app: weekly schedule (Hungarian sample) Personal trainer app: public home page (Hungarian sample)
Hand-coded samples for made-up businesses, with made-up names. Not client work. These samples are in Hungarian for now.
You don’t want an app. You want to stop being one.
How many sessions do I have left? Where’s my job at? Did you send the invoice? Same question, tenth time, 9 p.m., by text.
The answer lives in a spreadsheet on your laptop. You’re the only one who can read it, and the only one who knows which copy is current.
You ask a developer for a quote. It arrives weeks later, and you close the email.
So you try an AI builder. It looks great. Then you remember other people’s data would sit in it, and nobody can tell you who sees what.
That isn’t you being behind. Until now the choice was expensive or risky.
Who this is for
- People keep asking you the same things: sessions left, job status, whether the invoice arrived
- You track in a spreadsheet what other people should be able to see
- Everyone should see only their own data, and you want that tested, not assumed
- You want every sign-up in your CRM
- You’re on Pro + AI 6,000 or Premium, or ready to move up
Not for you if…
- You need payments inside the app. The security check rejects card fields. For selling, use the AI ecommerce store builder.
- You need data from another system, or scheduled messages. The app can’t call outside addresses and has no scheduled jobs.
- It has to run on your own domain. Apps live at yourapp.gammatica.ai; custom domains aren’t available yet.
- You want an app to download. It runs in the browser, on phones too, but there’s nothing to install.
- You need bulk invites or data export. For now you invite people one at a time and see the data inside Gammatica.
You say what it should do. The platform provides the lock.
1
Describe it in one sentence
Who signs in, what they do, what they see. That sentence is the whole brief.
2
Check the plan
Who signs in, what data it keeps, which pages it has, who sees what, and the expected credits. Nothing gets built until you say so.
3
The AI builds and tests it
It tests the app in a real browser, on desktop and phone, fixes what the test finds, and a separate reviewer checks it against your request. You then open a preview at its own address, on separate data.
4
Publish
The security check runs, and only what passes goes live. After that, you change it in the chat, and earlier versions can be restored.
What it’s used for
Three situations you’ll recognize.
Monday morning, four sites
Cleaners sign in on their phones, see their schedule, check off the list on site and upload a photo. The manager sees it all in one place.
The technician is on site
Work order on the phone, with photos and a refrigerant log. The manager sees whose maintenance is due, and no paper gets left in the van.
Why this is different
One sentence instead of a developer quote.
Same goal: people sign in and see only what’s theirs. One route takes weeks and several rounds. The other starts with a sentence.
Getting started
Spec, quote, weeks
One sentence, a plan, a few minutes of building
Sign-in and permissions
Built and maintained separately
Ready on the platform; the AI writes no code for it
Security testing
A separate line item, if it gets done
30+ checks before every publish
Changes
New quote, new round
Type it in the chat, and restore if you need to
New users
Copied into the CRM by hand, if at all
A verified sign-up becomes a contact
Companies that have already handed the work over
Don’t take our word for it.
4.7 / 5
real user rating
I’ve tried a lot of project management software, but finally here’s one that’s easy to use and meets high expectations.
I’ve been using Gammatica for over a month. We moved off Notion onto this platform quickly and painlessly.
We’ve tried many platforms, but I can finally see all our international campaigns in one place.
A 10/10 solution if you want to see what your team actually does each day.
Viktor and the team did excellent work rolling Gammatica out for us. Recommended.
Finally a calendar I don’t get lost in. I recommend it to everyone.
Anna
You don’t have to learn it. You have someone to ask.
Anna is the assistant built into the system. Not a generic chatbot: she knows Gammatica specifically, across about 300 topics, from credits to permissions to billing. Ask in a sentence and she answers; where it helps she shows you with a small animation and links you straight to the right screen.
- Ask in plain English, get a plain answer
- She doesn’t just describe where it is. She takes you there.
- Available at night too, with no ticket to raise

What people actually ask her:
How do I build a client portal where everyone sees only their own data?
Let me open it for you
What you want to know before you commit.
A real app. People sign in with their own account at its own address, add data, upload files, and see only what the rules allow. The rules and the data live on the server, not in the browser.
No. Sign-in, sessions and data storage come from the platform. The AI codes the screens and states who sees what in a closed rule format, which the platform turns into database conditions. It writes no SQL, handles no passwords, and can’t put its own password or card field on a page.
It runs before every publish, and it can’t be switched off. Test users try to read, change and delete each other’s data, without signing in and from another app. More than 30 checks, no AI involved. If one gets through, the app doesn’t go live: after up to two automatic fix rounds, the same check runs again. It’s an automated test, not an independent audit.
With a 6-digit email code or a one-tap link, or a password if you ask for one. Each role can have open sign-up, sign-up after your approval, or invitation only; an admin role comes by invitation only. Once a live sign-up verifies their email, they become a contact with a note about their role. An existing address links to the existing contact, with no duplicate. You approve, block and invite people from Gammatica.
Every AI round starts with a snapshot, and restoring an earlier version costs no credits. The live app doesn’t change until you publish again, and publishing runs the security check again.
Building a new app and publishing it are part of Pro + AI 6,000 and Premium. Building uses AI credits based on actual usage. You see an estimate first, repair rounds included, and if the work reaches 1.4 times the estimate, the AI stops and asks you. A running app uses no AI credits.
Partly. In the trial you describe your app and get the full plan: who signs in, what it stores, who sees what. Building from your description and going live need a paid plan. The three ready-made samples you can open right away (personal trainer, cleaning company, AC service) are in Hungarian only for now.
No payments, no calls to outside systems, no scheduled jobs, no custom domain, no bulk invites, no data export. People can’t yet download their own data or delete their own account themselves. For calendar-based booking with live availability, use the booking system.
