As answered by people managing Input Director and RONTGEN.
RONTGEN's answer:
"Currently in closed beta with early adopters from the medical and content creation fields."
RONTGEN's answer:
Next.js, TipTap, Tailwind CSS, and shadcn/ui on the frontend. Django, Django REST Framework, LangChain, and PostgreSQL on the backend.
RONTGEN's answer:
Built by a neuroradiologist who needed a faster way to write radiology reports. Existing tools were either chatbots or lacked voice transcription integration. RONTGEN was created to solve this problem and evolved into a general-purpose AI writing editor for anyone.
RONTGEN's answer:
Full control over prompts, models, and providers — no black boxes. One OpenRouter key unlocks 200+ models with no markup. Voice transcription is built into the editor, not a separate tool. Agent pipelines automate repetitive writing tasks that other editors require manually.
RONTGEN's answer:
Professionals who write frequently and want to integrate AI into their workflow — doctors writing reports, content creators, researchers, copywriters, and anyone who dictates and edits text regularly.
RONTGEN's answer:
Unlike chatbot-based AI tools, RONTGEN is a full rich text editor where you build custom agent pipelines — chain multiple AI steps (transcribe → refine → structure → conclude) and run them with one click. Combined with BYOK support for 10+ providers and built-in voice transcription, you own your entire writing workflow.
