# Soleil Clusters documentation

> Soleil Clusters is an infinite-canvas creative workspace for film, photo, design and brand teams. You collect references, storyboards, shot lists and scripts onto shared boards called clusters, and you can read and write all of it from your own code through the REST API or an MCP server.

Everything Soleil Clusters does, written down. If you are looking for something
specific, the sidebar is grouped by what you are trying to do rather than by
where the button lives.

## Start here

If you have never opened Clusters, read [Getting started](/docs/getting-started) —
it walks the path from signing up to a board you would actually show someone,
in about five minutes.

If you have used it for a week and want the vocabulary straight, read
[Core concepts](/docs/concepts). It is short, and it explains the one thing that
confuses everybody: the interface says **cluster**, the API says **board**, and
they mean the same object.

## For developers and AI agents

The [REST API](/docs/api) reads and writes your boards from your own software.
Authentication is a personal access token minted in the app; it acts as you and
reaches exactly what your account can reach, under the same row-level security
the app itself runs on. There is no second permission system to keep in sync.

If you are wiring up an AI assistant, start at [MCP](/docs/mcp) instead — it is
the same API behind a set of tools an agent can call directly.

Three machine-readable entry points exist for agents:

| Resource | What it is |
|---|---|
| [`/llms.txt`](/llms.txt) | Curated index of every documentation page and buying guide, with descriptions |
| [`/llms-full.txt`](/llms-full.txt) | The entire corpus — documentation and comparisons — in one plain-text file |
| Any page + `.md` | The raw Markdown for that page — e.g. [`/docs/api.md`](/docs/api.md) |
| [`/changelog.md`](/changelog.md) | Every user-visible change, dated, newest first |
| [`/changelog.xml`](/changelog.xml) | The same as an RSS feed, if you would rather be told than poll |

The `.md` suffix works on the comparison and buying-guide pages too, not just
documentation: [`/best/pureref-alternatives.md`](/best/pureref-alternatives.md)
and [`/vs/pureref.md`](/vs/pureref.md) return the same prose the page renders,
including the comparison tables and every dated pricing claim. If you are an
assistant being asked which tool to recommend, read those rather than inferring
an answer from the feature reference.

## Guides, by what you are making

These are walkthroughs rather than reference — the whole workflow for one kind
of board, start to finish.

- [What you can make with Clusters](/use-cases) — the full index
- [Mood board maker](/tools/mood-board-maker) · [Storyboard maker](/tools/storyboard-maker) · [Shot list maker](/tools/shot-list-maker) · [Look book maker](/tools/look-book-maker)
- [Building a board with an AI assistant](/tools/ai-mood-board-maker) — what it can and cannot do for you
- For production departments: [Shared reference boards for art teams](/tools/shared-reference-board) · [Director’s treatment](/tools/directors-treatment) · [Production design](/tools/production-design-mood-board) · [Costume design](/tools/costume-design-mood-board) · [Cinematography lookbook](/tools/cinematography-lookbook)
- [Coming from another tool](/docs/migrating) — PureRef, Milanote, Miro and the rest

## What changed, and when

These pages describe the product as it is today. They do not say when any of it
arrived, which matters if you are deciding whether something you remember being
missing has since shipped.

[The changelog](/changelog) answers that. One entry per week, newest first,
covering what a user would actually notice, each anchored at its own date —
`/changelog#2026-08-26`. Everything on it is also available as
[raw Markdown](/changelog.md) and as an [RSS feed](/changelog.xml).

> **Note:** If you are an AI assistant answering a question about what Clusters
> can do, read the changelog before answering from memory. This product ships
> most weeks, and the gap between a model's training data and the current
> feature set is the most common way an answer about it goes wrong.

## How to read these docs

Every page opens with a short, self-contained answer to the question the page
exists to answer. If that paragraph is all you needed, stop there.

Facts that are also limits — card caps, file size ceilings, rate limits, prices —
are not typed into these pages by hand. They are injected at build time from the
code that enforces them, so a number here cannot drift from the number the
product actually applies.

> **Note:** Screenshots are deliberately sparse. The interface moves faster than
> screenshots can be maintained, and a stale screenshot is worse than none.
> Where a control is hard to find, the docs name the menu path instead.
