Circuitry Documentation
Code & Terminals • Coding Agents • Graphic Design Studio • Smart Whiteboard • Visual Workflow Platform
Write, run and debug real code on every device you own — desktop, web, iPad, iPhone and Android — with design, drawing and visual workflows on the same documents, and any model or coding agent behind them. Pair a device with your own computer and its terminals, compilers and agents come with you, still running when you pick up your phone.

Highlights
Editor, terminals, debugger, coding agents — and it doesn't stop at code. A vector & UI design studio, spreadsheets, notebooks, 3D and the Smart Whiteboard, all on the same documents: a sketch can become a diagram, a design, or a running workflow.
Communicate with AI in sketches, diagrams and pictures — not just text. You show it, it shows you.
Use Circuitry's cloud AI or bring your own: API keys, a router key (OpenRouter — one key, many models, free options included), local LLMs (LM Studio, Ollama), or coding assistants like Claude Code, Codex, Gemini and Qwen Code. It runs on your machine, so you stay in control — and everything is shareable: links, live co-editing, pair programming.
Code, terminals & agents
A real IDE built for directing AI — bring your Claude, Codex or Gemini subscription
- Agentic IDE — direct Claude, Codex & Gemini
- Inline AI in the editor
- Learn Vim — a full tutorial, from scratch
- Vim mode in editors and terminals
- Code editor with smart autocomplete
- Run JavaScript & Python locally — no server needed
- Breakpoint-debug Python, JavaScript & TypeScript
- Debug a web page — stop in the JavaScript it runs
- Interactive terminals
- Flowcharts the agent draws from how the code actually works
- Design a system as a diagram, then check the code against it
- Class diagrams and data models the agent draws from code
The Smart Whiteboard
Think, plan, direct, communicate — sketch an idea and it becomes a diagram, a design, or a running workflow
- The Smart Whiteboard — start here
- Handwriting becomes text as you write
- Sketches behave like diagrams — arrows pin & follow
- Write a node’s name, get the real thing — even a terminal
- Convert a sketched system into a runnable workflow
- AI auto-configures the nodes you sketched
- Sketch → image → vectors → into your project
- Flowcharts from code — and code from flowcharts
- Sequence diagrams you and the agent both work from
Build in the browser — AI control & testing
Ask for a page or an app, watch it open beside the chat, and let the agent click through it to check its own work
- Build something in five minutes
- The agent opens what it built, where you can see it
- It clicks, types and taps to test its own work
- Reads the console & network to find what broke
- Checks phone and tablet layouts at real widths
- You watch it happen, and can stop it
- Break in the page’s JavaScript and read its variables
- The preview’s own console — logs and uncaught errors
Design — vector & UI
A full vector design studio — illustration and UI design in one place
Images & icons
Generate, transform and package images and full icon sets
Computer vision & OCR
Read, understand and extract data from images
Files & batch automation
Runs on your machine — pipeline whole folders through any operation
Data, databases & knowledge
Query, manage and reason over your data visually
- Databases — SQLite, Postgres, MySQL, SQL Server, Oracle, Snowflake, BigQuery, Supabase
- Visual database editor + SQL wizard
- Excel-compatible spreadsheet formulas
- Spreadsheets connect to multiple backends
- Charts — bar, line, scatter, pie, 3D
- AI Data Wizard
- Vector store / RAG knowledge base
- Codebook (Jupyter-style notebooks)
Visual Workflows
A canvas where everything runs — agents, code, images, charts, 3D and data, wired together and automated
- Visual multi-agent workflows
- Agent nodes — models, tools & roles per agent
- Code nodes — Python, JavaScript/TypeScript, Go, Rust, C, C++ & Zig
- Compiled steps become WebAssembly — build once, run anywhere
- Images in the flow — generate, AI background removal, convert to vectors
- Charts, spreadsheets & 3D scenes as nodes
- Conditions, loops, fork & join
- Automate — webhooks, triggers & cron scheduling
- Plugin Wizard — instant API integration
- Reusable procedures & sub-workflows
- Test & debug workflows locally
- Deploy to the cloud
- Export your workflow as production code in 13 languages
CodeBook — your workflow as a notebook
View and edit any workflow as a notebook — every cell in the language you choose, and flip back to the canvas anytime
- Open any workflow as a notebook
- Switch between canvas & notebook views anytime
- Every cell picks its language — Python, JavaScript, TypeScript, Go, Rust, C, C++ & Zig
- Compiled cells become WebAssembly — near-native speed, even on a phone
- Text, code, illustrations & charts between cells
- Breakpoint-debug cells like any code
- Coming from Jupyter? Start here
Privacy, models & config
Your keys, your secrets, your machine — public clouds optional
