From download to your first batch.

Create an account, then start your evaluation from the account page. It is the whole app on one machine for 14 days, with a Seat’s 70,000 tokens of model time and no card. One per account. The download appears on the same page as soon as it starts.

There are two builds of the same app. The installer adds a Start Menu entry and a proper uninstall, and studio IT can push it silently with /VERYSILENT. The single .exe runs from wherever you put it. Neither needs administrator rights.

Open the app and choose Sign in with your browser. It opens this site in your usual browser. Sign in there the way you do here, choose Activate this machine, and you are sent straight back. The app never sees your password.

Each machine you activate uses one seat. To move to another computer, free the seat from your account page first. After that the app checks its licence every 14 days, not each time it opens, and keeps running for up to 28 days without reaching us. Making and retuning objects still need a connection, because both call a model.

The app starts on its built-in shapes, so you can make something straight away. A shape is the set of fields one kind of object has, and the normal range of each. To work from your own game, click Built-in shapes at the foot of the sidebar, or Open a project on the welcome screen, and choose one of these.

Have a spreadsheet instead? Import a spreadsheet, under the message box, brings CSV or TSV rows in as a batch. They are checked, drawn and turned into all 10 formats like anything the app makes. Nothing is generated, so it uses no model time.

What it reads from your project

Your existing objects are read from JSON, YAML, CSV, TSV, Godot .tres and Unity .asset files. Unreal’s own .uasset files can only be written by the editor, which is why new Unreal objects come out as CSV. Folders that hold only build output, like Unity’s Library and Unreal’s Intermediate, are skipped. Each engine has its own page with the exact files: Unity, Unreal and Godot.

1. Pick the kind of object in the picker beside the message box, and how many: one to twelve a run. The 2D and 3D switch says which you are making: sprites and icons measured in pixels, or assets measured in metres.
2. Describe them in a sentence and press Forge, or Enter.
3. Read the cards. The line under each name says how many of its numbers sit inside their tier. Every number has a ruler: the band is the tier’s range and the needle is the value. On built-in shapes the band is the stated range. On your project it is where 90% of that tier’s existing objects sit.
4. Change anything. Click a number to type a new one, or drag its needle. CtrlZ undoes.
5. Take the code. Pick one of the 10 language tabs and copy the batch. With a project open, Save to project shows every file it would write, and whether each one is new or replaces one, before anything is written.

The icons and 3D blockouts are drawn on your machine from each object’s id. They are free and the same every time. An image render is different: a model makes it, so it uses model time, and only when you ask. Each one is kept on disk, so the same object never costs twice.

Retune changes objects that already exist, so it needs a project open, or the demo project.

1. Switch the top bar from Make to Retune, then pick the kind of object and the number to move.
2. Say what changed, in a sentence. For example: We changed the damage formula. Rescale everything and keep the tier curve intact.
3. Read the plan. It shows each tier’s old range and its new one, and every object’s value before and after. Nothing is written until you apply.
4. Apply. The app changes that one value in each object’s own file and leaves the rest of the file alone. It cannot undo that from inside the app, so commit or stash your project first.

The model only proposes each tier’s new range. Moving every object into it is plain arithmetic, the same for every object in the tier, so each one keeps its place: the strongest stays the strongest, and nothing overtakes anything. That is also why a bigger project does not cost more: the model is shown the ranges, not the objects. Try it on the demo

Your project is never uploaded. The app reads it on your machine and sends only what each request needs: your sentence, the fields of the kind you picked, and the few existing objects it has to match. A retune sends each tier’s range rather than the objects in it.

On your plan’s model time, requests pass through our servers, which count the tokens and keep the count, not the content. Save your own key in Settings instead, Anthropic for making and retuning or Gemini for image renders, and those requests go straight to that provider without touching your plan.
