Fluig

Fluig costs nothing to use. It is a free AI diagram generator where you describe an idea or hand over a document in a chat, and it builds the visual for you.

Output types include mind maps, flowcharts, tables and cards, so Fluig covers more than one kind of diagram from a single starting point.

Once a diagram exists, you can convert it into another format in one click.

That helps when a rough mind map needs to become a flowchart for a team review, without redrawing anything by hand.

The chat-driven approach means you spend your time describing what you want and refining the result rather than dragging shapes around a canvas.

Fluig sits in the AI charting and whiteboard space and is geared toward teams and creatives who share ideas visually.

The free pricing makes it easy to test on a real document before you commit any workflow to it.
