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...
ContextForge is persistent, searchable memory for AI coding agents — built on the Model Context Protocol (MCP). Your AI assistant forgets everything when the session ends. ContextForge fixes that: save architectural decisions, naming conventions, and debugging context once, and any MCP client...

As answered by people managing RONTGEN and ContextForge.dev.
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.
ContextForge.dev's answer:
Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.
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.
ContextForge.dev's answer:
ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol — so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.
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.
ContextForge.dev's answer:
Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.
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.
ContextForge.dev's answer:
Software developers and engineering teams who use AI coding assistants — Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf — and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.
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.
ContextForge.dev's answer:
ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once — Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf — not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing — all through a single MCP server you add with one command.
