Graspable is a desktop studio for XR. Say what you want, an AI agent builds it as a real project on your computer, checks that it runs, and you try it on your headset.

For macOS and Linux. Windows is coming soon. Free with your own AI account.
The examples are scenes you could ask for, running live in your browser.

Apps people built from a request in plain words and published. The four in front are this week's most opened and liked.

Built something? Show it on Discord, or publish it and make it public: it appears here by itself.
Building on your computer with your own AI account stays free. A configurator, a training or a walkthrough of a real place is the kind of project studios are hired to build. A plan adds what gets one finished sooner.
Move a project to the cloud and the agent keeps working while your computer sleeps. Move it back when you like.
On every plan, paid with Credits. A new account gets 6 Credits once: an hour to try it. How it works
On larger projects the agent writes only the lines that change, finds code by what it does, and reads less build output.
With Pro and higher. How it works
Start much further along
Seven premium templates
Walk through a generated world, measure a scanned real room, stage a product, start from a working game, or build an app for bare hands. Ask for a new place and it is generated for you.
With Builder and higher. How it works
Share a cloud project with your team. Everyone works on the same copy, and the Credits come from one pool.
With Studio, from 3 seats. How it works
Paid plans include Credits every month. When a project needs more, buy any amount from 50 Credits. They last 12 months. Building on your own computer never uses Credits.
$0.15 to $0.20 a Credit
Builder$20 a month
150 Credits a month
Premium templates.
Pro$40 a month
250 Credits a month
Everything in Builder, native XR with Unity, Unreal Engine and Apple Vision Pro, and Fast mode.
Studio$99 per seat a month
500 Credits a month per seat, pooled
Everything in Pro, a team with shared projects, and your own cloud.
Sign in with a ChatGPT subscription, use Claude Code with your Claude subscription, or add an API key from Anthropic, OpenAI, OpenRouter and others. Local models work too. Keys live in your computer's keychain, and new models show up without an app update.
Every file change, command, check and cost is in the run. Undo a whole run with one click.
Record a session in the emulated headset. It is replayed after every change, so an interaction that worked keeps working.
Preferences and project decisions are kept as plain files. You can read, correct, pin or forget each one.
Everything runs on your computer. Move a project to a cloud sandbox to keep it running while you are away, and move it back.
Being worked on now.

What to do after installing is on the download page.
More in the documentation.
The app is free. You bring your own AI account: an API key from Anthropic, OpenAI or another provider, a ChatGPT subscription, or Claude Code with your Claude subscription. Plans add Cloud Agents and premium templates; you do not need one to build.
No. You describe what you want and the agent writes the project. The code is a normal React Three Fiber project on your disk, so developers can read and edit it at any time.
Anything with a WebXR browser, such as Meta Quest and Apple Vision Pro. The app also has an emulated headset in a scanned room, so you can try a scene before you put one on.
Not unless you choose to. Projects, previews, builds, keys and sign-ins stay on your computer. With a plan you can move a project to a Cloud Agent so it keeps running without your machine, and move it back.
Yes. A ChatGPT subscription signs in directly. A Claude subscription works through Claude Code, which the app can install and sign in for you. Anthropic allows a Claude subscription only inside Claude Code, so using Claude in the built-in agent needs an API key.
A run only finishes when the project builds and loads in a real browser without errors. If you recorded headset sessions as tests, they are replayed too. Failures go back to the agent for up to three repair rounds.
