Use cases
What teams do with Whimsical through Elaichi
Every one of these runs inside the access the person already has, and lands in the same audit log.
-
Product
Turn a written spec into a flowchart
Paste the spec or point at the doc, and the agent drafts the user flow as a Whimsical flowchart in the right workspace. Review it, ask for a branch to be added, and it edits the board in place.
-
Design
Sketch a first wireframe from a brief
Describe the screen and the agent generates a wireframe you can open and refine in Whimsical. Ask for a second version with the navigation moved and it updates the same board.
-
Engineering
Diagram the system before the review
Hand over the service names and how they talk to each other, and the agent draws the architecture diagram and tidies the layout. Change a dependency later and ask it to redraw the affected part.
-
Marketing
Map a campaign as a mind map
Start from a theme and a launch date, and the agent builds a Whimsical mind map of channels, messages and owners. Add a branch for each new idea as the planning call goes on.
-
Operations
Keep the workspace tree in order
Ask what lives in a folder, move stale boards to an archive folder, or delete the duplicates left over from a workshop. The agent walks the file tree so you do not have to click through it.
-
Research
Work through comments on a board
Ask for every open comment on the journey map and get them summarized by theme. Reply to the ones you can resolve and leave the rest for the author, all without leaving the chat.
Try asking
- “Turn the onboarding spec into a flowchart in the Product workspace”
- “Draft a wireframe for the new settings page”
- “Summarize the open comments on the checkout redesign board”

FAQ
Frequently asked questions
How do I connect Whimsical to Claude?
Connect Whimsical in Elaichi first, which opens Whimsical's own sign-in window where you approve access over OAuth, with no client ID or secret to generate. Then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Sign in to Elaichi when Claude asks and Whimsical is ready to use.
Does Whimsical work with ChatGPT and Cursor as well as Claude?
Yes. Once Whimsical is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, the Elaichi Agent and any other MCP client. You connect Whimsical once and every client sees it.
What can an AI agent actually do with my Whimsical data?
An agent can search your Whimsical workspaces, open a board or doc, and generate flowcharts, mind maps and wireframes from a plain description. It can edit an existing board, tidy the layout, move or delete files, and read and reply to comments. Short, concrete asks such as "add a login step to the checkout flow" work better than long paragraphs.
Does connecting Whimsical give the AI access to every workspace?
No. Every call to Whimsical runs as the person who signed in, so the agent only sees the workspaces, boards and docs that person can already open in Whimsical. Elaichi can narrow that further with restrictions, but it can never grant more than Whimsical itself allows.
Can I stop an agent from deleting or changing things in Whimsical?
Yes. Restrictions in Elaichi apply per action, so you can allow searching and creating in Whimsical while blocking delete, move or edit. A restricted action is never advertised to Claude, ChatGPT or Cursor at all, so no prompt can reach it.
What happens to a Whimsical connection when someone leaves?
Offboarding that person in Elaichi ends their access to Whimsical through every client at once. A Whimsical connection they shared keeps working for everyone else on the team. If you want it gone entirely, disconnect Whimsical once in Elaichi and it disappears from Claude, ChatGPT, Cursor and the Elaichi Agent together.
Does the Whimsical MCP connector work with Gemini, Codex, Claude Code or other MCP clients?
Yes. Whimsical is reached over the same MCP endpoint every client uses, so anything that speaks MCP can call it — Gemini, Codex, Claude Code, Windsurf, Cline, Zed and OpenCode among them — alongside Claude, ChatGPT, Cursor, and the Elaichi Agent. The tools on offer and the access behind them are identical whichever client asks. Only the setup screen differs.
Is Elaichi an alternative to Zapier MCP for Whimsical?
Yes. Both let Claude, ChatGPT or Cursor use Whimsical. Zapier MCP fits a team that already automates in Zapier, since each person signs in and acts as themselves in that account. Elaichi fits when IT wants one address for the whole company, per-tool rules by role, and a record of every Whimsical call.
How is Elaichi different from Composio for Whimsical?
Composio gives AI agents tools and sign-in handling across 1,000+ apps, for developers building agents or people using an assistant, billed per tool call. Elaichi gives a company's own people governed access to Whimsical: one address, restrictions per role or user, and $15 per user per month. Both have role permissions and a log of every call.
