AI-assisted data annotation companion for faster, smarter labeling
The extension proposes likely labels or annotations as you work, so you can confirm a suggestion instead of classifying each item from zero.
Runs entirely in the browser via the Chrome Web Store, with no server setup, plugin dependencies, or account creation required.
Acts as a companion layer over the annotation pages you already use, so there is no need to migrate your dataset or tooling.
The developer declares that user data is not sold or shared and is not used for unrelated purposes.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.

Design, test, and govern APIs — now with AI agents in the loop

The environments frontier AI trains on, and the agents that do the recurring work
Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
One browser agent that combines every major AI model with web automation
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

AI data infrastructure for building production-grade models
Organize, search and export your AI chats across ChatGPT, Gemini, Claude and Grok
The multimodal data layer for computer vision and physical AI teams

Dedicated diagramming platform with strong AI chart generation, but less focus on freeform collaborative brainstorming whiteboards.
SpecialistInstantly turns natural language prompts into mind maps and flowcharts, but offers less freeform canvas drawing flexibility.
Combines whiteboarding and documentation with AI generation, but lacks Whimsical's specialized wireframe shape library.
