An AI-powered visual workspace where teams think, plan, and build together
An infinite multiplayer board where cursors, comments, and live editing let remote and hybrid teams work in the same space simultaneously.
Docs, Tables, Slides, Kanban, and Timelines live alongside freeform drawing so a workshop can turn directly into a structured plan.
Generate diagrams, tables, and summaries, remove image backgrounds, and connect external AI assistants through the MCP server.
6,000-7,000+ templates for brainstorming, workshops, roadmapping, and process mapping give teams a running start.

Analyze, optimize and organize prompts in one AI workspace
Describe a goal and get a structured, ready-to-use prompt, then convert it into a reusable template with variables and presets for future reuse.
See what works and what needs improving in an existing prompt, then let the optimizer rewrite rough drafts into stronger versions for your target model and format.
Reverse-engineer an image, video, URL or piece of text into a reusable prompt you can adapt for your own projects.
Save, tag and organize your best prompts, and track every version created through generation, optimization, refinement and reverse prompting.
