Describe what you want to create. Maestro helps you plan it, builds your application and helps you improve it.
Coming soon to macOS 13 and later. Free during the beta.
Your brief
Recording: one button at the start of the meeting. That is all.
Transcription: on your machine, never in a cloud.
The summary: key points, decisions and next actions.
Each task shows where the work stands.
Local transcription
Amélie builds, Félix checks her work.
You: let's revisit the non-compete clause.
Client: my concern is still the geographical scope.
You: we will limit it to the region. I am noting that down.
Meeting summary
Your meetings, transcribed. Nothing leaves your machine.
Record, transcribe, get the summary. No uploads, no account.
Your product's versions
You describe your idea. Describe the tool you dream of in a conversation. Margaux, the analyst, turns it into a clear project.
You approve before work continues. No AI rushing ahead: the brief is written before your eyes. You read, correct, and work only continues when you say “Looks good to me”.
You see what still needs doing. Marcel prepares the tasks. The board shows what is ready to build, being built, needs finishing or is done.
The team builds, you follow. Amélie builds your application. Félix checks the result. In Product, “Right now” shows who is working and on what.
Try your tool inside the app. Without waiting for the end, you open Minute, click through, watch the meeting summary being written and point out what needs to change.
You prepare the launch. Your partners want the tool? Léa prepares its introduction page, ready to share and faithful to what you have built.
You improve your application. Feedback from the firm, an idea for improvement: return to the Workshop and the team starts from what is written, without breaking what works. Every version remains available.
The team
Each specialist takes the stage in turn. Hover over a seat to pause on that person.
Analyst
Margaux
She scopes your idea and turns it into a clear project.
You : I would like an app where people in my neighborhood can swap plants, but I do not know where to start.
MargauxAnalystMargaux : We start with them. Who are these neighbors, and what stops them from doing it today? Everything else follows from that.
You : Put that way, it is already clearer.
« Tell me about your idea as you would tell a friend. I will take care of the structure. »
Vibe coding starts with code. Maestro starts by understanding what you are building.
Five-figure quotes, a developer you cannot find, a no-code tool that locks you in: your idea was waiting. Describe it. The team scopes it and writes the specification; you approve it, and the build starts from that text. Every change returns to it, so nothing gets lost along the way.
The overflowing spreadsheet, the software nobody maintains anymore: provide them as they are, without cleaning anything first. Your working rules emerge in writing, including the ones nobody had documented. The new tool is built alongside the old one. Your business keeps running during the work, and you switch on the day you choose.
Two starting points, the same method behind them.
Who it is for
The prototype impressed everyone; the next version broke it. Here, she describes, approves, and the product moves forward every day, without raising funds or hiring.
The file that keeps the business running, with dates entered as text and duplicates no one dares to sort out. They describe their work in their own words; Maestro builds the tool.
The team's AI produces quickly, and no one knows who decided what anymore. Here, criteria are set before the code and every decision is recorded: nothing to reconstruct afterward.
“I fix one thing, it forgets two.” Here, tests are written before the code, and the code belongs to them, with clean version control: they stay in control and save hours of setup work.
Trust
Your idea has no business being on someone else's server. Your product, documents, and decisions live on your machine: no Maestro server sees them.
A key left lying around in a file will eventually leak. Yours are stored in macOS Keychain, never as plain text, never with us.
A tool that requires its own cloud has a hold on you. Online backup is a choice, using your own account, and everything can stay offline.
Maestro shows costs in dollars when you use an API key, or tells you what is included in your AI subscription.

Yes. With Maestro, you describe what you want in everyday language, direct the work and approve each stage. The code exists and belongs to you, but you do not need to open a terminal or an editor: everything happens in a clear interface.
Maestro is a desktop application for macOS 13 or later, not a web service. Your ideas, code and documents stay on your machine. The comparison covers the differences point by point: see /comparatif.
Vibe coding starts with code: you ask, it codes, you ask again, and after a few weeks nobody knows what the product does anymore. Maestro starts by understanding what you are building, with scoping followed by a specification you approve. Every change starts from that written foundation, so your product moves forward without losing what worked. Full comparison at /comparatif.
Yes. Provide the existing tool as it is, and Maestro extracts your working rules for you to review. The new tool is then built alongside the old one, and your data moves over once it can do everything the old one did. It is the second starting point on the home page: /#chemins.
Your whole project stays on your machine, including version history. No Maestro server sees your projects: the app talks directly to the AI assistants you configure. If you wish, you can back up online to your own private account.
The app is free during the beta. AI usage costs are billed through your subscription or keys, by your provider: nothing passes through Maestro. The Maestro subscription will be announced at the end of the beta.
Yes, all four: Claude Code, Codex, Cursor and Mistral Vibe. You choose your assistant and model and can switch at any time, even in the middle of a conversation.
Your data stays on your machine and your API keys live in macOS Keychain, never in plain text or in a Maestro cloud. You control what leaves your computer. More details at /vos-donnees.
Nine agents share the work: understanding your idea, preparing the plan, designing screens, building and checking. You talk with Maestro and approve the important decisions.
Yes, entirely. The generated code belongs to you and lives on your machine, in a standard format you can open or take elsewhere whenever you want. Maestro does not lock you in: it helps you, it does not hold you back.
You will be able to download without creating an account, and the beta opens in waves. Leave your email: we will notify you as soon as your turn comes, and that is all we will do with your address.
Not yet: Maestro is coming to macOS first (13 or later), and the Windows version is in development. Leave your email to be notified when it is released.
