AI tools by job · DiagramForge Studio

AI diagram maker

Drawing a diagram by hand means placing every box and arrow yourself, then doing it again when something changes. DiagramForge starts from one sentence or from a file you already have. It works out what kind of diagram you need, groups the boxes into lanes, draws the arrows in the order things happen, and marks failure paths separately. You can drag any box, rename it, add arrows, and walk through the diagram one step at a time before you download it.

Who it's for

Developers explaining a system, an API flow or a database
Students drawing flowcharts and ERDs for assignments
Teams mapping a business process or an approval flow
Consultants and managers who need an org chart or a process map

What you get

A diagram with shapes for steps, decisions, people, databases, queues and tables
Lanes for teams, tiers or phases that never overlap
A walkthrough that explains each box in one sentence
Checks for boxes with no arrows and, for systems, single points of failure
SVG and PNG images, Mermaid code, SQL tables and JSON

How it works

Describe what you want to draw, or add a schema.sql, docker-compose.yml, Mermaid file or notes.
In Adjust, pick the diagram type, direction and look, or let AI decide.
Press Draw diagram (1 credit). The board appears with lanes, boxes and arrows.
Drag and edit boxes for free, then download SVG or PNG, copy Mermaid or get the SQL.

Example request

“Hospital patient admission process with a triage decision and a path for emergency cases.”

What comes back

Lanes for reception, triage and the ward
A triage decision with labelled Yes and No arrows
A dashed emergency path that skips the queue
A walkthrough note on every step

Tips for a better result

Say what the diagram is for: explaining, planning or documenting.
Add your schema or compose file to get every real table or service by name.
Ask for lanes when different teams or systems are involved.
Use the box below the board to add a step or a failure path later.

Questions

Is it free?

Drawing a diagram costs 1 credit, and guests get 2 free credits every day (5 with a free account). Each AI change from the box below the board costs 1 credit. Dragging, editing boxes yourself, checks and downloads are free.

Which diagrams can it draw?

Software architecture, flowcharts, business process maps, database ERDs and org charts. If you are not sure, leave the type on Let AI decide and describe what you want to show.

Can it draw my database from a SQL file?

Yes. Add your schema.sql and every table is drawn with its real columns, primary keys and foreign keys. You can also download the tables back as PostgreSQL CREATE TABLE code.

Does it work with Mermaid?

Yes. Copy any diagram as Mermaid code for GitHub, Notion or Markdown. You can also edit the Mermaid code in the Code view and press Apply to redraw the board, for free.
