Gather visual direction, set, props and per-deliverable shots on one board — then share a single link. Your client views it and adds their own brand references and feedback with no account, no app, no sign-up. The link just works.

Clients don't run SaaS accounts and they shouldn't have to. Send one link; they open it on their phone or laptop and see exactly the direction you are proposing — and add brand assets, competitor references or feedback of their own, instantly.
Cobalt connects to Claude over MCP. Tell it the brand, the deliverables, the visual direction, and Claude creates the board, sorts columns by deliverable, pulls reference images, and writes direction notes — from a single message.
Cobalt maps to how a client campaign actually comes together — direction first, then agreed deliverables. Build the direction, pull in the client, lock the brief.
Start a board and lay out columns: visual direction, set and props, talent, palette, per-deliverable shot lists. Drag in references, paste image URLs, write direction notes.
Send the link to your client. They open it with no account and add brand assets, references and feedback — so the campaign direction is agreed before you ever load a card on shoot day.
Keep a searchable library of every campaign board — organized by client, brand or quarter. Full-text search pulls up the exact reference set when the next brief lands.
Cobalt exposes an MCP server — the protocol Claude uses to work with external tools. Add your token in Settings, or connect via OAuth on claude.ai, and Claude can build, populate and reorganize your boards by chat.
Tell Claude: "Build a moodboard for a Q3 product campaign — visual direction, set, talent and three deliverables, eight reference images, a direction note per column." It creates the board, organizes the columns, pulls reference images from the web, and writes the notes. Then you share the link.
It works with all your boards: search across your whole library, create boards and columns, add notes, links and images up to 25 MB, and move or rename cards — all from a single conversation.
Build your first brand campaign board, then share it with your client — no sign-up required on their end. Cobalt is invite-only today; request access to get started.
