RONTGEN is now open — AI writing tool with voice-to-text and custom agents

RONTGEN is now open for signups — AI writing tool with voice-to-text and custom agents Hey IH! Quick update: RONTGEN is now open for everyone — no invite code needed. For context: I'm a radiologist and solo founder from Brazil. I built RONTGEN to solve my own problem — dictating medical reports and having AI format them automatically. Stack: Next.js + Django + LangChain, built almost entirely with Claude Code as my AI coding partner. What's working: → Free tier with full editor access → Voice-to-text streaming transcription → Custom AI agent pipelines → Copilot with GPT, Claude, Gemini, DeepSeek → BYOK (bring your own API keys) Would love feedback from the community.
