Profile

I'm a software architect working on AI tooling and MCP. Last August I started writing again—by hand, every morning at 7am—after a 30-year detour from literature into engineering.The workflow to transform handwritten pages into something shareable was painful: photograph, transcribe, edit, pair with an image, format. Each step a context switch.So I built Vibrant Frog Collab to do it my way.Core philosophy: AI enhances, doesn't replace. The app has guardrails baked in that can't be overridden—it won't generate content from scratch, only help develop what you've already written.Features: - Handwriting scan → instant transcription - AI collaborative editing with memory across conversations - Quo
