Chartado is a text-to-diagram tool for developers: type a flow like User -> Query Agent -> Vector DB -> LLM and it renders an animated AWS or AI-architecture diagram. No drawing tools, no alignment fiddling.
Type a description, get an animated diagram. No manual layout, no pixel pushing.
A dead-simple syntax that reads like a sentence. Describe connections with arrows, fan-out with braces. The diagram renders instantly.
User -> Load Balancer -> App Server
App Server -> Database -> Cache
Show branching, parallel processing, and broadcast patterns with curly braces. Nested chains with parentheses. Chartado handles the layout.
Notification Hub -> {Email, SMS, Push}
Record the animation and drop the file into a README or a slide deck, or grab the current frame as a still. Every format is free. WebM and PNG record in the editor on this page without an account; the other four (WebP, GIF, MP4, PDF) are in the app after a free sign-up.
Visualize agentic AI workflows, RAG pipelines, and multi-model orchestration with the same simple syntax.
Show how a query agent retrieves context from a vector database before sending it to an LLM. The entire pipeline in a single line.

User -> Query Agent -> Vector DB -> LLM -> User
A router agent classifies intent and dispatches to specialized agents for research, code generation, or analysis. Fan-out with curly braces.
See the full animated multi-agent router diagram →
User -> Router Agent -> {Research Agent, Code Agent, Analysis Agent}
A ReAct agent that decides between calling a tool or returning a direct response. Pipe syntax for conditional branching, multi-line for loops.

User -> Agent -> LLM -> |Tool, Response|
Tool -> Agent
Open any diagram, edit the text, and watch the flow move. Each one is a live example you can run in the editor.
Serverless REST API diagram
API Gateway takes the request, Lambda runs the code and DynamoDB keeps the data.
Pub/sub fan-out diagram
SNS hands the same event to two Lambdas and a queue at the same time.
Queue worker diagram
The first Lambda only enqueues, so the API answers at once and the worker takes as long as it needs.
Event pipeline diagram
The same event goes down a three-hop chain and straight into S3 at the same time.
RAG pipeline diagram
The question reaches the vector database before the model is called, and the animation shows it.
Multi-agent router diagram
A router agent in front of three specialist agents, drawn in one column so nobody reads them as a pipeline.
ReAct tool-calling diagram
Each turn the model calls a tool or answers, and a tool result goes back to the agent for another turn.
Human-in-the-loop diagram
A guardrail sends each output to Accepted or to a person, and the person's verdict goes back to the agent.
MCP architecture diagram
The agent talks to its MCP client and nothing else; the tools sit behind the server.
Cloudflare Workers diagram
A Worker reads one of KV, R2 or D1 per request, and the animation shows which one.
The boxes are the parts of an agent system (LLM, agents, the tools they call, a vector database, guardrails) and the arrows are who talks to whom. In Chartado you type that as one line such as User -> Agent -> LLM -> User and it draws the boxes, each with an icon picked from its name, then sends a message hop by hop along the arrows. That travelling message is the animated part.
Type User -> Query Agent -> Vector DB -> LLM -> User and Chartado draws it straight away. The animation then walks a message along that line, out to the vector database, on to the LLM and back to the user, which is the part a static drawing does not show.
Yes, with braces for the fan-out. User -> Router Agent -> {Research Agent, Code Agent, Analysis Agent} draws the router fanning out to the three agents and the animation follows the message out to each of them. Chains inside the braces go in parentheses, and a second line from any agent back to the router closes the loop, which covers supervisor and orchestrator patterns too.
Six formats, every one of them free. WebM, WebP, GIF, MP4 (H.264) carry the animation; PNG or PDF give you a still frame. WebM and PNG record in the editor on this page without an account, and the other four are in the app after a free sign-up.
The editor is never capped — animate as many diagrams as you like. Free saves 3 of them to the cloud; Pro saves 100. Every icon, export format and piece of syntax is on both plans.
