RONTGEN is an AI-integrated text editor. Instead of a chatbot, it's a full rich-text editor (a paginated document, like a word processor) with AI built into the writing surface — for people who write or dictate documents regularly across medical, legal, academic, and content work.

Core capabilities

• Voice-to-text dictation with a personal keyterms dictionary that learns domain jargon (eponyms, drug names, abbreviations). Providers: AssemblyAI and Deepgram, plus in-browser local transcription.
• Custom agent pipelines — chain AI steps (transcribe → fix terminology → apply a template → add a conclusion) and run them in one pass.
• AI copilot — draft, transform a selection, or compare wording across models, inside the document.
• Every major model in one place — GPT, Claude, Gemini and others through a single connection; switch between them freely.
• Local and private models via Ollama — open-source models run on your own machine, so text stays local.
• Bring your own API keys at cost (no markup), or use built-in monthly credits and non-expiring credit packs.
• Community Library — share and import agents, templates, and shortcuts.
• Cloud documents across devices and PDF export.

Stack: Next.js, TipTap, Tailwind CSS and shadcn/ui (frontend); Django, Django REST Framework, LangChain and PostgreSQL (backend).

Originally built by a neuroradiologist to speed up radiology reporting, now a general-purpose AI writing editor.
