Lucid Train vs Miro

Lucid Train is a desktop coding harness that draws architecture diagrams from a codebase and passes the diagram to a coding agent as a specification. The agent emits a semantic graph, and the ELK layout engine positions diagram elements and routes edges. Diagrams are Excalidraw scenes that can export to SVG and PNG or become Markdown specifications; Mermaid support and diagram import are also listed. Proposed edits appear as diffs, and commands use risk tiers, with catastrophic commands refused. Model options include local Ollama, OpenRouter, other OpenAI-compatible endpoints, and hosted cloud models. Repository files are processed locally; prompts and code go to the selected provider, or nowhere when using local models. The maker says it collects no telemetry, analytics, prompts, code, or usage data from local or bring-your-own-key sessions. API keys are stored locally or in the OS keychain. Connectors include GitHub, Vercel, Railway, and Grafana, plus arbitrary stdio MCP servers; remote HTTP and SSE servers cannot connect directly. The free CLI is open source. The native app costs $2.50 per month, billed $30 a year, and includes a 7-day free trial.

Miro is a collaborative visual workspace for teams planning strategy, designing products and services, and managing processes. It supports diagramming, wireframing, brainstorming, journey mapping, product planning, and goal setting. Its AI tools can turn sticky notes into diagrams, synthesize research findings, and summarize boards. Teams can choose from 7,000+ customizable templates, present work, run live workshops with timers and voting, or record Talktrack walkthroughs for asynchronous viewing. Miro connects to 250+ tools, including Jira, Asana, Slack, Figma, Microsoft Teams, and Google Workspace, and offers APIs and SDKs for custom applications. It runs on Android, iOS, macOS, Windows, and the web, with an API platform. The free plan allows unlimited boards to be created and shared, but only the three most recent remain editable. Starter costs $8/user/mo billed annually, and a 14-day trial is listed. Enterprise pricing is custom, from 30 members, and includes security and governance controls plus regional data hosting options.
