Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

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.
Industry standard collaborative whiteboarding with massive template libraries, but less streamlined for rapid AI diagram generation.


Delivers structured data science and coding courses with interactive playgrounds, but focuses heavily on data analytics rather than general software engineering.
#2
SpecialistTeaches computer science and logic through visual interactive puzzles and an AI tutor, but lacks traditional text-editor coding playgrounds.

SpecialistFocuses on hands-on browser-based Linux and DevOps labs with AI guidance, rather than general multi-language programming fundamentals.
Free / Open-sourceCombines mind mapping and project workflows with AI agents, but less focused on pure visual diagramming and wireframes.
Robust collaborative whiteboard with strong AI diagramming tools, but less polished UI wireframing capabilities than Whimsical.

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.
Exceptional UI wireframing and prototyping tools, but less versatile for general mind mapping and freeform brainstorming.
