Technical Documentation That Actually Stays Up-to-Date.
Your docs are outdated the moment they’re written. Ludflow connects to your GitHub repos, analyzes your code, and generates documentation that evolves with your codebase — diagrams, API references, and architecture docs included.
The Problem
Why Your Team Stops Reading (and Writing) Docs.
The cycle is always the same: someone writes great docs during a launch. Three months later, the code has changed but the docs haven’t. Engineers stop trusting them. New hires get confused by stale information. Eventually, everyone just reads the code directly — defeating the entire purpose of documentation.
The real problem isn’t that your team is lazy. It’s that keeping docs in sync with a moving codebase is a full-time job nobody signed up for.
Docs Rot Overnight
Your architecture doc was accurate when it was written. That was 6 months and 200 PRs ago. Now it’s actively misleading.
Nobody Volunteers to Update
Writing docs is thankless work. Updating someone else’s stale docs? Even worse. The result: documentation debt compounds silently.
New Hires Pay the Price
Your onboarding process is “read the docs” — but the docs describe a system that no longer exists. New engineers spend weeks reverse-engineering from code.
The Solution
AI-Powered Context Mapping: From Codebase to Knowledge Base.
Ludflow doesn’t just store your documentation — it generates and maintains it. Connect your GitHub repos and Ludflow analyzes your code to extract API endpoints, functions, database operations, and dependency maps. Describe what you need in plain English and get production-ready diagrams. Everything stays searchable and current through scheduled code sync.
Here's what that looks like in practice
FEATURE
Describe It. Ludflow Builds It.
Stop fighting with drag-and-drop diagram tools. Tell Ludflow what you need in plain English, and it generates diagrams — flowcharts, sequence diagrams, ERDs, Gantt charts, mind maps, state diagrams, class diagrams, and more.
- Natural language input — describe your system and get a diagram in seconds
- Guided AI wizard asks clarifying questions before generating
- Chat-based refinement — say "make the auth flow more detailed" and watch it update
- Versioning — explore alternatives without losing your current work
- Voice input for hands-free diagramming during whiteboard sessions
- All 8+ Mermaid diagram types: flowcharts, sequence, ERD, Gantt, mind maps, state, class, pie
FEATURE
Your Codebase, Documented Automatically
Connect your GitHub repositories and Ludflow analyzes your code to extract functions, API endpoints, database operations, environment variables, and dependency maps. Get an auto-generated API documentation catalog without writing a single line of JSDoc.
- One-click GitHub OAuth connection — no GitHub App installation required
- Automatic extraction: functions, API endpoints, DB operations, env vars
- Scheduled sync (daily/weekly/monthly) keeps documentation current
- Ask your codebase questions in natural language through unified chat
FEATURE
One Chat to Search Everything
Ludflow's unified chat is the single entry point for your team's knowledge. Ask a question in natural language and get answers pulled from your documentation, your codebase, or both — with citations you can verify.
- RAG-powered semantic search — finds answers even without exact terminology
- Citations with slideout previews — click a reference to see the source
- Search docs, edit documents, and query code from the same chat
- Intent classification routes your question to the right source automatically
- Code search across connected GitHub repositories with function-level precision
How It Works
From Zero to Documented in Four Steps
Connect
Link your GitHub repositories with one-click OAuth. No GitHub App installation, no complex setup. Ludflow starts analyzing your code immediately.
Generate
Ludflow extracts functions, API endpoints, database operations, and env vars from your code. Describe system architecture in plain English and get Mermaid diagrams — flowcharts, ERDs, sequence diagrams, and more.
Sync
Set a sync schedule (daily, weekly, monthly) and Ludflow re-analyzes your repos automatically. When your code changes, your documentation updates. No manual intervention.
Search
Everything Ludflow generates is instantly searchable through unified AI chat. Ask questions about your codebase, architecture, or API endpoints in natural language and get cited answers.
