Coming soon for FileMaker Pro
Zefyl puts an AI developer inside FileMaker Pro. Talk to it in Zefyl Companion, a chat panel beside your file, or from Claude Code or Codex. It plans the tables, builds the layouts and scripts, clicks through every screen to test them, writes the documentation, and keeps only what you approve.
One email when it launches. Nothing else.
Describe a whole system. The tables and links appear in FileMaker while the chat works through the plan you approved.
Circle what you want changed, right on the FileMaker window, and add a note. It knows which fields you marked.
It clicks through every screen like a person, finds what’s broken, fixes it and runs every test again.
Ask your records a question and get the answer, a chart, and a card to approve before anything changes.
One morning check-up across every FileMaker Server, with anything that needs you waiting on a card.
Two ways in
Zefyl is one product with two ways to work. Both come in the same install and the same plan.
Start here
Zefyl CompanionInside FileMaker. The guided way.
A chat panel beside your open file. Point at the screen, describe what you want, and watch it land.
Best for
For developers
Zefyl AgentInside Claude Code or Codex. The toolbox way.
The same Zefyl, from the Claude Code or Codex you already work in. You drive, with your own prompts and habits.
Best for
Same install, same plan. Use either one, or both on the same file.
Before and after
You know how to build a FileMaker system. Zefyl takes the clicking, checking, writing up and babysitting off your plate, so your time goes on the part only you can do.
Clicking through every layout after each change, hoping nothing broke.
It clicks through for you, and shows you a screenshot of anything that broke.
Describing a layout change in an email nobody reads twice.
Circle it on the FileMaker window, add a note, send. Done while you watch.
Inheriting a file nobody can explain.
Ask what the file does. It looks around first, then explains it in plain words.
Documentation you mean to write at the end.
Written as it builds, with a change log of every change, kept in the file.
Logging in to each server to check backups and disk space.
One morning check-up across every server, in one chat.
Building a report so someone can answer one question.
Ask the question. Get the answer, the records behind it and a chart.
Being nervous about changing a live system.
A checkpoint before every change. Undo is one click.
Zefyl Companion
A chat panel next to your open file. You talk, it builds, and you see every change land in FileMaker.
How it works
Big asks become a plan and a list of small tickets. Each one is built, tested and reviewed before it’s kept, so you can step away and come back to finished work.
Say what the system is for and who uses it. Bring a spreadsheet, an old file or a sketch. It asks what it needs to know.
Data models, diagrams and mockups open in a FileMaker window beside your file, so you can look before anything is built.
A short plan and a list of tickets: the tables, the screens, the scripts. Change anything before a single field is made.
Each ticket is built, tested and reviewed by a fresh pair of eyes. Turn on auto-keep and clean passes are kept while you’re gone.
FileMaker opens on what was made, the documentation is up to date, and anything that needs you is waiting on a card.
Guided mode does the asking for you. Describe what you want, check one blueprint card, tap Build it, and follow a single progress card until it’s done.
Layouts
Testing
Your data
Servers
Zefyl Agent
Everything Zefyl can do, from the agent you already use. You write the asks, it opens FileMaker, does the work and checks it.
Who does what
The decisions stay with you. The building, clicking, checking and writing up don’t.
Describe the module and who uses it.
Asks what it needs to know, then sketches the data model and screens for you to look at.
Approve the plan.
Builds it ticket by ticket, testing each one before it’s kept.
Circle what you’d change on the screen.
Changes it while you watch, then runs every test again.
Decide what’s ready to keep.
Writes the documentation and change log as it goes.
Ask “how are the servers?”
Checks every server and brings back only what needs you.
The data, the screens, the scripts, the testing and the paperwork, in one place, working on your real file.
Tables, fields and relationships, planned from your description and built in your file.
Lists, forms and detail screens, laid out the way an experienced developer would.
Modern, app-style screens inside FileMaker, for the places a native layout can’t go.
One page that holds your look, so the whole system feels like one product.
Written, run and checked before you see them, and explained in plain words whenever you ask.
Diagrams, data models and mockups in a FileMaker window, before anything is built.
Every screen clicked through and screenshotted, and the tests run again after each change.
A readable health report on any file, with the safe fixes done for you.
What each part does and why it was made, plus a change log of every change.
Status, logs and backups for every FileMaker Server you connect, from the same chat.
One-click updates, and a short note on what’s new after each one.
Ask your records a question, get the answer and a chart, and approve every edit.
Compare
Zefyl Go is free. It works in Claude Code or Codex, builds and designs your system, checks your files and servers, and takes screenshots of FileMaker. Zefyl Pro adds everything else the Zefyl plug-in does inside FileMaker Pro, which is what lets your AI see, click and test the app you’re building, in both ways of working: Zefyl Companion beside your file and Zefyl Agent in Claude Code or Codex, on one plan. The last column is Claris’s ADK on its own, so you can see what Zefyl adds.
During the beta, everything here is free until January 1, 2027. After the beta, every install starts with 14 days of everything in Zefyl Pro. Then a free Go key keeps the Go features running on as many Macs as you like, and a Pro subscription keeps all of it.
Nothing is built until you’ve seen the plan. If it has to change, it asks again.
Your file is saved as it was before each change, so undo is one click.
Choose per chat: look only, change with your OK, or build freely.
Zefyl runs on your Mac with the AI account you choose. Your files and records don’t come to us.
Bring your own subscription. Zefyl connects it to FileMaker and teaches it how FileMaker work is done.

If you want to point at the screen and be guided, Zefyl Companion. If you already work in Claude Code or Codex and like being in control, Zefyl Agent. Most people end up using both.
Yes. They come in the same install and the same plan, and work on the same files. Use Zefyl Companion for one project and Zefyl Agent for the next, or both on the same day.
Yes. On an existing file it looks around first, explains what it found, and only then suggests changes. Local files and files hosted on FileMaker Server both work.
No. Guided mode asks what you want, shows you one plan to check, and builds it when you tap Build it. Experienced developers can talk to it like a colleague and skip the guidance.
Every change starts from a checkpoint and ends on a card you keep or undo. You choose per chat whether it may only look, change with your OK, or build freely. For the busiest files, work on a copy first.
Zefyl runs on your Mac and works through the AI account you choose. Data chats see only what your FileMaker account can see. Your files and records don’t come to us.
