What is DiagramGPT by Eraser?
DiagramGPT is an AI‑powered diagram generator created by Eraser that lets users create technical diagrams from plain‑language or code‑based prompts. It leverages OpenAI’s models to automatically classify the input and generate diagrams in a diagram‑as‑code format, which can later be edited inside the Eraser platform for technical design and documentation. The tool is designed to lower the barrier to creating professional diagrams, especially for engineers, architects, and technical writers who need visual artifacts but don’t want to wrestle with drag‑and‑drop tools.
DiagramGPT supports several diagram types, including flow charts, entity relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. Users can start from presets or write their own prompts describing components, data flows, or services, and the AI will render a diagram that captures the structure and relationships. After generation, diagrams can be refined with follow‑up prompts or manually adjusted inside Eraser, enabling both AI‑assisted and direct‑editor workflows.
The tool is aimed at software engineering teams, cloud architects, product managers, and technical documentation authors who need to quickly sketch system designs, data flows, or workflows. Because it integrates with Eraser’s broader docs‑and‑diagram suite, users can embed generated diagrams into larger technical documents, collaborate around them, and keep diagrams in sync with evolving designs. The focus is on technical accuracy, repeatability, and developer‑friendly workflows rather than generic marketing visuals.
DiagramGPT by Eraser pricing
Pricing model: Free
DiagramGPT offers a free tier with no credit card required, allowing individual users to generate diagrams on the public diagramgpt page. Paid plans are tied to Eraser’s team tiers: Starter, Business, and Enterprise, which unlock additional features such as API access, team collaboration, and enhanced editing and export capabilities. The API is only available to teams on Starter, Business, and Enterprise plans, while the exact subscription pricing for members is listed on Eraser’s main site rather than directly on the DiagramGPT page.

Frequently asked questions about DiagramGPT by Eraser
What types of diagrams can DiagramGPT draw?
DiagramGPT currently supports five main types: flow charts, entity relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. Each type is generated from a prompt that describes components, data flows, or services, and the AI renders an appropriate diagram structure for that category.
Can I edit my generated diagrams after they are created?
Yes, you can edit diagrams in Eraser, the docs‑and‑diagram platform built for engineering teams. After generating a diagram, you can click an option to save and open it in Eraser, where it can be edited using Eraser’s diagram‑as‑code syntax as well as through GUI controls for layout and styling.
Is there an API for DiagramGPT?
Yes, there is a DiagramGPT API that allows programmatic access to generate diagrams. The API is documented publicly, but it is only available to teams on Eraser’s Starter, Business, and Enterprise plans, not on the free individual tier.
Do I need to sign up to use DiagramGPT?
You can use the basic diagram‑generation functionality on the public DiagramGPT page without signing up, but signing into Eraser is required if you want to save, edit, or share diagrams, or use follow‑up prompts and advanced layout controls.
Will my prompts or diagrams be used to train AI models?
No, neither OpenAI nor Eraser will use your prompts or diagram content to train AI models. Eraser may analyze your usage patterns and metadata to improve and enhance its AI features, but the actual diagram content is not reused for model training.
How does DiagramGPT handle technical accuracy in diagrams?
DiagramGPT uses OpenAI’s models to interpret your prompt and map it to a diagram‑as‑code structure, aiming to reflect the components, connections, and relationships you describe. For higher accuracy, it is recommended to write detailed prompts that explicitly name services, data stores, and flows, and then refine the diagram through follow‑up prompts or manual edits in Eraser.
Can I share DiagramGPT diagrams with my team?
Yes, once diagrams are saved into Eraser, they can be shared with your team via Eraser’s collaboration features. You can also export diagrams to standard formats and embed them in documentation your team uses, making it easier to align around designs and architectures.
Are there templates or presets available?
Yes, DiagramGPT provides presets under a ‘Load a preset’ option that you can use as starting points. There is also a use‑case video library that demonstrates common patterns, which helps users quickly move from idea to a working diagram without writing everything from scratch.
Who created DiagramGPT and what is Eraser?
DiagramGPT was created by the team at Eraser, leveraging OpenAI’s models. Eraser (eraser.io) is an AI‑powered tool for technical design and documentation, designed for engineering teams to create, edit, and share diagrams and associated documents in a collaborative environment.
What is planned for future improvements to DiagramGPT?
The team is actively working to improve diagram accuracy and layout customization, as well as to expand the range of supported diagram types. They also encourage users to suggest new features or diagram formats by reaching out via email, Twitter, or their Slack community.
