AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
Run and build with open AI models locally or in the cloud
Install once and pull open-weight models by name; Ollama handles weights, quantization and versioning for you.
A built-in server exposes a straightforward REST API, so scripts, editors and agents can talk to local models with minimal setup.
Route requests to hosted open models when your laptop cannot hold the checkpoint you need, with per-token pricing and concurrency tiers.
Access families such as Llama, Qwen, DeepSeek, Gemma, Mistral and gpt-oss from a single interface.

SpecialistAutomatically embeds visual diagrams directly inside text documents, though it lacks Eraser's specialized cloud architecture focus.
#3
Free / Open-sourceOpen-source platform for building visual agentic workflows and RAG pipelines using local or cloud models.


Free / Open-sourceFeature-rich self-hosted web chat interface designed to manage and query local models like Ollama.
Free / Open-sourcePrivacy-first desktop app focused specifically on local document chat and RAG, unlike Ollama's general-purpose CLI runtime.

Free / Open-sourceDevelopment framework for connecting local models to external document stores and structured data sources.

Provides extensive drag-and-drop shapes and templates for general diagrams, but weaker automated code-to-diagram capabilities than Eraser.
Free / Open-sourceOpen-source desktop app for running models locally with a graphical interface, but heavier than Ollama's lightweight CLI.
Combines team whiteboarding, documentation, and diagramming in one platform, but less tailored for automated codebase architecture.
Free / Open-sourceOpen-source local AI server supporting multimodal inference including vision and speech, expanding beyond Ollama's text focus.
Free / Open-sourceLocal coding agent that executes natural language instructions directly inside your terminal environment.
