Question 1

What is Gramit?

Accepted Answer

Gramit is a free, browser-based hierarchical diagram editor that lets you create flowcharts, system architecture diagrams and nested subflows. It supports multiple node types including shapes, code blocks and icons, with both light and dark themes and sketch-style rendering.

Question 2

Is Gramit free to use?

Accepted Answer

Yes. Gramit is free, with no board limit and no trial that expires, and you can start drawing without an account. Signed out, boards stay in your browser. An account is optional and adds sync across devices and publishing to the public gallery.

Question 3

Can an AI assistant generate a Gramit diagram?

Accepted Answer

Yes. Gramit boards are also a small YAML language whose full specification is published at https://www.gramit.io/docs/ai for assistants to read. Ask an assistant to read the spec, describe the diagram you want, and paste the YAML it returns into the Code to Diagram panel.

Question 4

Are diagrams saved to a Gramit account private?

Accepted Answer

Yes. Boards saved to an account are encrypted on your device before they are uploaded, so they cannot be read on the server. Nothing becomes public until you choose to publish it.

Question 5

What types of diagrams can I create with Gramit?

Accepted Answer

Gramit supports flowcharts, system architecture diagrams, entity-relationship diagrams, mind maps, process diagrams and any hierarchical diagram with nested subflows. You can use shapes (rectangle, ellipse, diamond), text, person, icon, image and code nodes.

Question 6

Does Gramit work offline?

Accepted Answer

Yes. After the first load the editor keeps working with no connection, and boards saved in the browser stay available. Syncing to an account and publishing are the only parts that need to be online.

Question 7

What are alternatives to Gramit?

Accepted Answer

Gramit is comparable to Excalidraw, draw.io (diagrams.net), Miro, FigJam and Lucidchart. Its structural difference is first-class support for hierarchical nested subflows, where each node can contain an entire sub-diagram, and the fact that boards can be written and read as YAML.
