Coming soon for FileMaker Pro

Your next FileMaker system, built while you watch.

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.

Two ways in

Use it beside FileMaker, or from your agent.

Zefyl is one product with two ways to work. Both come in the same install and the same plan.

Start here

Zefyl Companion

Inside 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

  • Anyone, including people new to AI
  • Whole systems from a description
  • Drawing on the window and asking your data

For developers

Zefyl in your AI agent

Inside 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

  • Developers who live in their agent
  • Fitting into the way you already work
  • Tests kept as files in your project

Same install, same plan. Use either one, or both on the same file.

Before and after

The parts of FileMaker work nobody misses.

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.

BeforeWith Zefyl

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 developer that sits right beside FileMaker.

A chat panel next to your open file. You talk, it builds, and you see every change land in FileMaker.

How it works

From idea to working system, without the grind.

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.

Describe it

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.

See it first

Data models, diagrams and mockups open in a FileMaker window beside your file, so you can look before anything is built.

Approve the plan

A short plan and a list of tickets: the tables, the screens, the scripts. Change anything before a single field is made.

Walk away

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.

Come back to it done

FileMaker opens on what was made, the documentation is up to date, and anything that needs you is waiting on a card.

New to AI?

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

See the design before it’s built.

Zefyl in your AI agent

Already live in Claude Code or Codex? Stay there.

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

You make the calls. It does the legwork.

The decisions stay with you. The building, clicking, checking and writing up don’t.

YouZefyl

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.

Everything a FileMaker build needs.

The data, the screens, the scripts, the testing and the paperwork, in one place, working on your real file.

The whole data model

Tables, fields and relationships, planned from your description and built in your file.

Native layouts

Lists, forms and detail screens, laid out the way an experienced developer would.

Web viewer app layouts

Modern, app-style screens inside FileMaker, for the places a native layout can’t go.

One Style Sheet

One page that holds your look, so the whole system feels like one product.

Scripts that run

Written, run and checked before you see them, and explained in plain words whenever you ask.

The Playground

Diagrams, data models and mockups in a FileMaker window, before anything is built.

Tested like a person

Every screen clicked through and screenshotted, and the tests run again after each change.

File check-ups

A readable health report on any file, with the safe fixes done for you.

Documentation in the file

What each part does and why it was made, plus a change log of every change.

Your servers

Status, logs and backups for every FileMaker Server you connect, from the same chat.

Always up to date

One-click updates, and a short note on what’s new after each one.

Chat with your data

Ask your records a question, get the answer and a chart, and approve every edit.

Compare

What each way gives you.

One plan covers both, so this is about how you like to work, not what you pay for.

Nothing is built until you’ve seen the plan. If it has to change, it asks again.

A checkpoint before every change

Your file is saved as it was before each change, so undo is one click.

You set how far it goes

Choose per chat: look only, change with your OK, or build freely.

Your files stay yours

Zefyl runs on your Mac with the AI account you choose. Your files and records don’t come to us.

Works with the AI you already pay for.

Bring your own subscription. Zefyl connects it to FileMaker and teaches it how FileMaker work is done.

Questions.

What is founder pricing?

Everyone who subscribes in the first month after launch pays $39 a month or $399 a year instead of $49 or $499, and keeps that price for as long as they stay subscribed.

Is there a free version?

No. There’s one plan with everything in it, and a 14-day trial so you can try all of it on your own files before you pay.

Zefyl Companion or Zefyl in my AI agent: which should I use?

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 in your agent. Most people end up using both.

Can I use 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 your agent for the next, or both on the same day.

Does it work on files I already have?

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.

Do I need to know anything about AI?

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.

Could it break a live system?

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.

Where does my data go?

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.

What do I need?

A Mac, a current version of FileMaker Pro, and a Claude Code or Codex subscription.

When can I get it?

Soon. Leave your email and we’ll write once, on the day it’s ready.

Spend your time on the work only you can do.
