Online Diagram Maker for Teams
Make processes, systems, and relationships easier to understand. Create diagrams with shapes and connectors, adapt a template, and work through the details together on one Boardmix canvas.
Start from a blank canvas or a template. Keep your diagram editable as the work changes.
- Choose the right structureMatch the diagram to the question you need to answer.
- Draw and explain togetherKeep labels, comments, and supporting material close.
- Share an editable boardGive reviewers the access they need.
START WITH THE QUESTION
Choose a diagram for what you need to explain
A process, a database, and a team structure need different views. Use these six starting points to find the right diagram maker, examples, and templates.
UML diagrams
How does the software behave or fit together?
Model classes, interactions, or use cases with a view that fits the design question.
Explore the UML diagram maker →ER diagrams
How are the data entities related?
Map entities, key fields, and relationships before refining a database structure.
Explore the ER diagram maker →Architecture diagrams
Which components connect?
Explain major services, interfaces, and dependencies without mixing in every implementation detail.
Explore architecture diagrams →Organizational charts
Who reports to whom?
Make teams, roles, and reporting relationships easy to follow as the organization changes.
Explore the org chart maker →Mind maps
How do the ideas branch out?
Organize a topic, explore its subtopics, and turn scattered thinking into a clear structure.

Build your diagram with shapes, connectors, and labels
Start with the objects you need to explain. Connect related items, name the relationships, and use a consistent direction so readers can follow the diagram.
- Give shapes a purpose. Use a decision shape for a question, or a class or entity shape when the contents need their own structure.
- Make connections explicit. Label branches such as “Approved” and “Needs changes” instead of leaving readers to infer the outcome.
- Keep the view focused. Put supporting notes beside the diagram rather than forcing every detail into each box.
FROM A QUESTION TO A READABLE DIAGRAM
How to make a diagram online
Choose one audience and one question before you start. Here is how to turn a request-approval process into a useful first diagram.
- 1
Choose the view and scope
For “What happens after a request is submitted?”, choose a flowchart. Start at submission and end when the request is approved; include the revision loop when changes are needed.
- 2
Add the steps and exceptions
Place Submit request, Review request, and a decision: Approved? Connect Yes to Confirm approval. Connect No to Revise request and back to review. Label both branches.
- 3
Review it with the people involved
Ask the requester and reviewer to follow each path. Add missing steps, simplify unclear labels, and share the board with the permissions they need.
THE RESULT
A request flow with an explicit revision path
The decision has two labeled outcomes. A revised request returns to review rather than stopping at a dead end.
ONE WORKSPACE, MORE THAN ONE VIEW
Keep related diagrams and their context together
A workflow explains the steps; a roadmap shows timing; a concept map organizes the ideas behind them. Put related views on the same canvas so your team can move between the overview and the detail.
REVIEW THE WORK WHERE IT HAPPENS
Collaborate on diagrams without passing copies around
Invite teammates to the same board, edit together, and discuss the part of the diagram that needs attention. Comments help keep feedback attached to its context.
- Clarify an unclear connection. Ask what an arrow means or which condition leads to the next step.
- Keep the reasoning nearby. Add notes, images, and links that explain a decision or constraint.
- Make the next revision together. Update the shared board so reviewers work from the same version.

A CLEAR HANDOFF
Share the diagram with the right access
Send a board link when the diagram needs to stay editable. Choose viewing or editing permissions to match the review, and include enough context for someone opening it for the first time.
For a snapshot in a document or presentation, use the board’s available export options. A static copy captures the diagram at that moment; the shared board remains the place for live edits and comments.
Give the diagram a useful title
“Request approval: submission to decision” tells a reviewer more than “Process v3.” Name the system or task, show its boundaries, and explain any unfamiliar symbols.
Online diagram maker FAQs
What is an online diagram maker?
An online diagram maker lets you arrange shapes, labels, and connectors in a browser to explain a process, system, or relationship. Boardmix combines diagramming with a shared canvas for notes, discussion, and teamwork.
What types of diagrams can I create?
You can create flowcharts, UML diagrams, entity-relationship diagrams, software architecture diagrams, organizational charts, and mind maps. Boardmix also provides shapes and templates for other technical views, including BPMN and network diagrams. Choose a structure that matches the question you need to answer.
Is Boardmix a free diagram maker?
You can begin with a free Boardmix account. The pricing page explains current board and object limits, export options, and paid features.
Can I use AI to start a diagram?
Boardmix AI can help draft supported formats such as flowcharts and mind maps from a prompt. Describe the process or topic, then review the output and edit the connections. Use the relevant diagram tools for specialist structures; do not assume an AI draft checks UML notation, database constraints, or system behavior for you.
Can I collaborate with people in other locations?
Yes. Invite collaborators to the same board and assign the access they need. Use real-time editing and comments to work through a diagram together; a shared link does not automatically give every recipient editing permission.
Do I need a template to make a diagram?
No. Use a blank canvas when you want to define the structure yourself. A template is useful when its notation and starting layout fit your task; replace its example labels and remove elements you do not need.
Which diagram should I use for a technical system?
Use an architecture diagram to show major components and connections, an ER diagram for data entities and relationships, or a UML view for a specific software structure or interaction. A flowchart is useful for the steps and decisions in a process. Keep these views connected, but give each one a clear purpose.
