Nova. The AI workspace that ships.
Say what you want in your own words. Nova plans the work, writes the files, runs the code, checks it and shows you the result. On your desktop or in your browser. Free to start, unlimited with your own key.
NovaSlow mornings,
strong coffee.
Small-batch roasts, poured with patience.
See the menuEverything ships with the app.
No plugins to hunt down, no setup afternoon.
Files and terminal
Reads, writes and edits files in your folder and runs commands, asking only before anything risky.
Browser and desktop
Opens pages, clicks, reads and tests. On Windows it can also drive other apps, only when you allow it.
Supernova mode
Plans, builds in proven steps, verifies, then a second model reviews it. For work that has to hold.
Skills, MCP, plugins
Dozens of ready skills, Figma and DESIGN.md among them, and any MCP server you add.
Keeps going
Close the window and a running task carries on in the tray. Code written so far stays safe in your account.
One account
Your chats and plan follow you between the app and the web. One allowance, shared.
Makes real videos
Describe a promo or explainer and get an MP4 with motion and sound, checked frame by frame before it is called done.
Design with a point of view
A library of design styles keeps pages from all looking the same: it picks one on purpose and builds in it.
Opens any file
Zip, rar, PDF, databases, model weights and more: it looks inside and tells you what is there.
Meet Nova.
A small pixel star that lives next to the text box. It is the Nova star from our logo, rebuilt from 15 × 15 squares, lit from the upper left. It blinks, looks around, and has its own animation for everything the app can be doing: listening, thinking, writing, researching, working. In Supernova mode it explodes into a golden star. Click it, then pick a mood.

Quick answers.
Is the free plan really free?
Yes. Free is $0 with normal usage and a 64K context. Local runtimes and your own API keys are always unlimited on every plan, because they do not use our compute.
What can Nova touch on my computer?
Only the folder you give it. It asks before anything risky, and on Windows it can drive other apps only when you allow it.
How do I cancel?
In one click, in Settings, Account, Manage subscription. You keep the plan until the end of the period you paid for.
Which platforms are supported?
Windows, macOS (beta) and Linux as a desktop app, plus the web at studio.valerois.com. Files, terminal and desktop control live in the desktop app; the web version builds in a browser workspace you can preview and download.
What is Valerois besides Nova?
Valerois is the company behind Nova and an AI research lab. Its research is Heimdall, a constant-memory hybrid architecture. See Research.
