Soleil Clusters

Overview

Soleil Clusters is a shared visual workspace for film, photo, design and brand teams that need references, storyboards and production material in one connected place. It is most convincing for collaborative, reference-heavy projects that also need written briefs and an API. The main trade-off is scale: the free tier welcomes collaborators but sharply limits cards and uploads.

Key features

An infinite canvas with live cursors, comments and presence lets a team develop a board together instead of exchanging static files. Built-in documents keep briefs beside visual material, with slash commands and @mentions for structured writing and discussion. Tags collect references across the workspace, while a relationship graph links cards and boards, useful when a project spans research, planning and production stages.

Images, video, audio and PDFs dropped onto a board become cards with viewers or players; other file types remain downloadable cards. Private object storage and expiring signed URLs keep files out of a public bucket. Deleted clusters stay recoverable in the trash for 30 days, which provides a useful recovery window without implying permanent retention.

Boards are private by default. You can invite collaborators or create a view-only public link that opens without an account. That is practical for client review, but it is not an editing handoff. Presentation mode and PNG or PDF export provide additional ways to present finished work.

For technical teams, the REST API at /api/v1 and MCP server support AI-assistant and custom integrations through OAuth or personal access tokens. One-time email codes handle sign-in, and API tokens are stored as hashes and can be revoked. The maker publishes weekly dated changelog entries, signaling an actively updated product. There is no general board importer: files can be dragged in, while screenplays can be imported as Final Draft or Fountain files.

Pricing

The freemium structure makes experimentation inexpensive, but the two plans serve very different workloads.

Demo

The Demo plan is free forever and does not expire. It includes 50 cards, unlimited clusters, unlimited collaborators and standard media support. Upload caps are 30 MB per video, 50 MB per audio file and 50 MB per PDF. Choose it for small teams, short projects or client-facing boards; the card ceiling and upload limits make it unsuitable as a growing production archive.

Creator

Creator costs $25 a month when billed monthly, or $20/mo billed annually ($240/yr). It removes the card ceiling, accepts any file type, imposes no per-file size limit and includes a 100GB drive. This is the practical tier for continuing libraries and media-heavy production, although teams should account for the annual commitment to obtain the lower monthly rate. There is no free trial.

Platforms

Clusters runs in a web browser and mobile browser, can be installed as a PWA, and has native iOS and Android apps. Its API and MCP server also make it suitable for workflows that extend beyond the main interface.

Who it's for

Film, photo, design and brand teams that organize visual references alongside briefs, schedules, shot lists or scripts are the natural audience. It also fits groups sharing work with clients who only need view access, and teams that can benefit from API-based automation. It is a weaker choice for anyone requiring a one-click migration from an existing board service or a large free asset library.

Pros and cons

• Pros: Infinite, real-time canvas and adjacent documents support genuinely collaborative planning.
• Pros: Tags, relationship graphs, presentation mode and PNG/PDF export connect organization with presentation.
• Pros: View-only links need no viewer account, reducing friction for reviews.
• Pros: API, MCP, OAuth and revocable hashed tokens offer unusually broad integration options.
• Cons: Demo is capped at 50 cards and modest video, audio and PDF upload sizes.
• Cons: Moving boards from another tool requires manual file handling; only Final Draft and Fountain screenplay imports are called out.
• Cons: Creator's best rate requires a $240 annual payment, and there is no trial.

Alternatives

For a broader mood-board directory, browse Mood Board Software. Choose Adobe Firefly instead when generative creation is the priority; its free plan offers limited daily generations. Milanote suits users wanting shared boards with a free allowance of 100 notes, images or links and 10 uploads. Pick Moodis for local mood boards and unlimited boards under its free personal, non-commercial plan. PureRef is an alternative for desktop reference-board work. Rayon is worth considering for editable models and limited PDF/DWG export on its free plan. ShopLook targets fashion-oriented creative canvases, with a free core and a $3.99 monthly Pro option. Kanvaz is a free, MIT-licensed desktop choice with no feature paywall. LibreMoodboards is a free, open-source Windows app with no subscriptions or paywalls.

Verdict

Choose Soleil Clusters if your film, photo, design or brand team needs live visual collaboration, briefs and connected production references, especially with API or AI-assistant integration. Look elsewhere if you need a generous free archive or automatic migration from another board tool. Creator is the sensible plan for serious ongoing libraries; Demo is best reserved for compact projects and review boards.
