Overview
What Eraser AI is
Eraser combines an infinite canvas, Markdown notes, and AI diagram generation in one technical documentation workspace. It is designed for architecture diagrams, sequence diagrams, entity-relationship diagrams, flowcharts, BPMN diagrams, and the design documents that explain them.
The useful distinction is that AI output is not a flattened image. Eraser produces diagram-as-code that a team can edit as text, refine with prompts, or adjust on the canvas. It can also begin with an existing image, Terraform or database-schema file, or connected Git repository.
Eraser is strongest when engineering teams want diagrams to live close to implementation work. Git sync, Eraserbot, an API, an MCP server, and integrations for GitHub, VS Code, Notion, and Confluence support that workflow, while reference libraries and custom rules help standardize output. Generated architecture still needs technical review before it becomes a system of record.
Use cases
Who Eraser AI is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Codebase documentation
Start from repositories or technical files and keep visual explanations alongside implementation context.
Collaborative design docs
Combine diagrams, Markdown notes, comments, version history, and stakeholder-ready exports in one file.
Capabilities
Core Eraser AI features
AI diagram generation
Creates sequence, ERD, cloud architecture, flowchart, and BPMN diagrams from natural language or technical source material.
Diagram-as-code
Represents supported diagrams in an editable DSL, making structure faster to change and easier to inspect than a static image.
Code and agent integrations
Connects with Git repositories and developer tools, while Eraserbot, the REST API, and MCP server support automated diagram workflows.
References and standards
Reference libraries, templates, rules, custom styles, and tech icons help teams create more consistent diagrams.
Collaboration and export
Supports comments, guests, shared files, version history, and exports including PNG, SVG, PDF, Markdown, Visio, BPMN, and draw.io where applicable.
Process
How the Eraser AI workflow works
Step 1
Choose the source
Describe the system in a prompt or begin from a diagram image, infrastructure file, database schema, or repository.
Step 2
Generate the structure
Let Eraser select a diagram type or choose one explicitly, then inspect the initial diagram and underlying code.
Step 3
Refine with context
Correct names and relationships, add references or style rules, and use prompts or direct edits to improve the result.
Step 4
Validate and publish
Have an engineer confirm the diagram against the real system before sharing, embedding, exporting, or connecting it to an automated workflow.

Assessment
Eraser AI strengths and limitations
Where it stands out
- AI-generated diagrams remain editable as code instead of becoming static assets
- Purpose-built for technical architecture and documentation workflows
- Can start from real implementation context such as repositories, schemas, and infrastructure files
- Broad collaboration, integration, automation, and export options
What to consider
- Generated diagrams can omit, mislabel, or invent relationships and require expert validation
- Per-member pricing can become significant for large editing teams
- The Free plan is limited to three files and three AI credits
- Extra AI and API usage on paid plans is separately metered
- Sensitive repositories and architecture details require an internal security and access review before connection

Eraser AI FAQs
What is Eraser AI used for?
Eraser is used to generate, edit, document, and share technical diagrams such as architecture diagrams, sequence diagrams, ERDs, flowcharts, and BPMN diagrams.
Can Eraser generate a diagram from a codebase?
Yes. Eraser can connect to a Git repository or accept technical files such as Terraform and database schemas. The resulting diagram should still be checked against the actual implementation.
Is Eraser AI free?
Eraser has a Free plan with three files, three AI credits, seven days of version history, and unlimited guests. Paid plans add more usage, privacy, history, and administrative features.
Can I edit an AI-generated Eraser diagram?
Yes. The output can be edited through Eraser's diagram-as-code DSL, refined with additional prompts, or adjusted on the visual canvas.
Does Eraser offer an API or MCP server?
Yes. Paid users can access diagram-generation APIs with usage-based billing, and Eraser also provides an MCP server for supported AI and coding clients.
Bottom line
Our Eraser AI verdict
Eraser is a strong fit for technical teams that want AI speed without giving up editable, maintainable diagrams. Its diagram-as-code model and repository-aware workflow are more useful than a generic image generator for living architecture documentation, but accuracy review and data-governance decisions remain the team's responsibility.
