I am Relwyn.
Ask me your question.
Desktop software · Mac & Windows
The Relwyn you know, as a native app for Mac and Windows — plus Workspace, a professional development environment where an agent builds, previews and publishes your projects with you.
Relwyn opens on a calm home screen — a greeting, your plan, your recent projects. From there, choose how you want to work, and switch at any time from the top bar.
The same Relwyn as on relwyn.com, in its own window — with your account, your plan and your synced history.
A complete development environment with Relwyn Workspace, the Relwyn coding agent. You describe, it builds — in your project folder, on your computer.
Desktop exclusive
Workspace turns Relwyn into a development partner. Open a project, explain what you want in plain words, and the Relwyn Workspace agent plans the work, edits the files, runs the commands and shows you the result — while you keep control of every change.
From an empty folder to a live site, in five steps you can repeat as often as you like.
Start a new project (saved in Documents/Relwyn by default), open any folder, or pick up a recent project.
A site, an app, a fix, a new feature: write it as you would brief a developer. Add screenshots or files if it helps.
It reads your code, plans, creates and edits files and runs the commands it needs, step by step, right in front of you.
Review each change in a before/after view, try it in the live preview, and ask for adjustments.
Put it online in one click, on a *.relwyn.com address or on your own domain.
Relwyn Workspace works directly in your project, with the tools a developer uses every day.
It explores and searches the project, creates, edits and deletes files, and shows every change before and after.
It installs dependencies, starts the development server and runs builds and tests in the built-in terminal (bash, or PowerShell on Windows).
It breaks big requests into a to-do list, checks diagnostics and fixes what fails until it works.
Several agent tabs per project, two side by side, a message queue — and pause, resume or stop at any time.
Paste or drop screenshots and mock-ups: with the Relwyn model, the agent uses them as a reference.
Each project keeps its own agent conversations, saved on your computer, so you can pick up where you left off.
When it’s ready, Relwyn uploads your project and puts it online, with HTTPS set up automatically.
Integrations work with your own accounts.
Move from one project to the next without losing your place.
Each eligible plan includes a Workspace credit counted in tokens and renewed every 30 days. The software’s settings show your balance, the reset date and the tokens used by each run — never an amount in euros.
A Workspace task does much more than a chat reply — reading files, running commands, iterating — so it uses about three times more tokens than an equivalent IA exchange. The multiplier is set by Relwyn and shown in the software. When the credit runs out, Workspace pauses until it renews; IA mode keeps its own daily budget.

Subscriptions are purchased only on relwyn.com and apply everywhere with the same account.
Workspace projects live in folders on your disk, and the agent works directly in them. To do its job, it sends Relwyn your instructions and the parts of the code it reads for the task in progress. Your project is only uploaded when you publish it — without hidden files, .env files, keys or certificates.
Workspace needs your computer — your folders, your terminal, your tools. That’s why it isn’t available on the website or in the mobile app: your subscription includes it, the software runs it.
The details that make a desktop app pleasant to live with.
Relwyn checks for new versions in the background and offers to install them right away. Each download is verified before it installs.
The interface, IA mode and the agent’s replies follow the language you choose in settings.
Sign in with Google or email: the same account, plan and history as on the website and in the mobile app. Workspace unlocks without a second login.
Bring your own API keys from the providers you already use, in IA mode and in Workspace — billed directly by the provider.
One installer per system — pick the one that matches your computer.

An internet connection is required. The software is downloaded from your Account and requires a paid plan (STARTER, PREMIUM or PRO).

No. It’s the same Relwyn, with the same account, the same plan and the same synced history. The software adds a desktop home screen and Workspace.
Any account with an active STARTER, PREMIUM or PRO plan. It’s included in the subscription — there’s nothing extra to buy.
In tokens, with a credit renewed every 30 days. A Workspace task uses about three times more tokens than an equivalent IA exchange (a multiplier set by Relwyn). The software’s settings show your balance, the reset date and what each run used.
Workspace pauses until the credit renews, or until you move to a higher plan. Your files stay untouched, and IA mode keeps working with its daily budget.
On your computer, in the folder you choose (Documents/Relwyn by default). The agent works directly in that folder; your project is only uploaded when you publish it.
Only on the website relwyn.com, from your account. The software doesn’t sell subscriptions: it sends you to relwyn.com. Your subscription then applies everywhere — on the web, in the desktop software and in the mobile app.
Only if you want those integrations. They use your own accounts, with the official GitHub and Stripe command-line tools installed on your computer.
No. Workspace needs your computer’s folders and terminal, so it’s reserved for the desktop software for Mac and Windows.
The software checks for a new version at launch and regularly in the background, then offers to install it. If a version becomes too old to connect, it asks you to update first.
