Brilliant for founders and small teams
Design is usually the thing you skip because there's nobody to do it. Brilliant is free: the whole tool, not a trial or a stripped-down tier. Auto layout, components, vector editing, effects, design systems, tokens, GPU shaders, ten export formats, Figma import, and unlimited MCP usage, on macOS and Windows.
The agent does the first draft. You do the taste.
Start from a sentence
Press / on the canvas, describe the outcome, and the agent builds it as native, editable elements: pages, dashboards, illustrations, diagrams, wireframes. Then you keep talking to it.
Build a dashboard stat card: a small label, a big metric number, a trend indicator, and a sparkline area below.
Nothing is flattened to an image, so when something is 80% right you fix the last 20% by hand instead of re-prompting forever.
Haven't connected a model yet? The chat opens in Playground mode and replays bundled demo conversations end to end, so you can watch how the agent behaves before committing a key.
On-brand before you have a brand
Every fresh project ships with a fully populated design system: colors, spacing, radius, type, all already wired. Ask the agent to use your tokens and it paints surfaces with roles like color.surface instead of hard-coded hex.
The payoff shows up the day you change your mind about the brand. Switch the theme or brand dropdown in the right toolbar and every screen re-skins at once. You can even have the agent author the new brand: "add an alternate brand called sunset with a warm orange primary" writes a sparse file into Styles/ and flips the canvas over to it.

Ship it somewhere
Export the selection to PNG, JPEG, WebP, SVG, PDF, HTML, React, MP4, MOV, or Replay. Copy a section straight to the clipboard as HTML, React, CSS, or an image and paste it into your codebase or a thread.
Or publish. A project goes live at brilliant.design with one toggle, and the link lands on your clipboard. Public is the default and it's free. Investors, contractors, and early users open the real editor in a browser, view-only, and can copy pieces out.
When you do bring someone in, invite them by email or @handle as a viewer or an editor. Editing is genuinely simultaneous: presence avatars show who's around, colored cursors show where they're working, and two people on different parts of the canvas never block each other. On a public project that costs nothing.
Already have assets somewhere? Figma files import directly, by pasting a file URL or through the Copy to Brilliant plugin, and Sketch files import too. You don't start from an empty canvas just because you started from another tool.
What it costs
The design tool is free forever, with no per-seat charge. Two things are paid: the built-in AI chat above ten messages a day, and keeping work private (private projects, private drops, share links). Bring your own API key on every tier, with no markup, and driving Brilliant from an external agent over MCP is never capped.
That shape is deliberate: free is for working in public, paid is for working in private. If your early work can live in the open, a small team can run on Brilliant without a line item.
The honest part
You still need judgment. The agent produces professional structure, auto layout, components, tokens, effects, but it doesn't know your positioning or which of three directions is the right one. Brilliant is also a static canvas: no click-through prototypes today. And the built-in chat needs a provider connected before the first prompt, even on Free.
A couple of platform edges are worth knowing before you plan around them: video export runs on macOS and Windows only, transparent video is macOS only, and the web editor needs a WebGPU-capable browser (Chrome, Edge, Safari 26 or later, or Samsung Internet).
