Platypus, a local meeting transcription, notes, and chat application.

Technical Positioning
A free, local alternative to Granola/Notebook LM, combining note-taking, live transcription, and knowledge base management, with on-device processing and user-provided LLM integration.
SaaS Insight & Market Implications
Platypus addresses enterprise demand for secure, local AI-powered productivity tools, specifically for meeting intelligence. Its 'on-device meeting transcription' via `whisper.cpp` and 'local knowledge base management' directly mitigate data privacy concerns associated with cloud-based solutions. The 'bring your own LLM' model offers flexibility and cost control, allowing enterprises to integrate with preferred or internal models. The automatic meeting detection without API access is a clever workaround for integration challenges. This solution caters to organizations prioritizing data sovereignty and seeking to enhance meeting efficiency and knowledge retention within a secure, self-hosted environment, reducing reliance on external SaaS providers for sensitive data processing.

Raw Developer Origin & Technical Request

Show HN: Platypus – Local meeting transcription, notes, and chat (Tauri, Rust)

Hi HN — I built Platypus as I wanted to combine note taking, live transcription and knowledge base management in one app. Granola / Notebook LM free local alternative. It's a Tauri/Rust desktop app that does on-device meeting transcription via whisper.cpp, notes in TipTap, and per-project HNSW vector search across your knowledge base. You bring your own LLM (Claude, OpenAI, Gemini, or local Ollama).A few things that were interesting to figure out:Zoom/Teams meeting auto-detection works via process inspection — Zoom spawns CptHost only during an active call (not when the app is just open), and Teams's audio.mojom.AudioService sub-process. No Zoom/Teams API access needed. Local Whisper works great - on Mac. Old PC experience not recommended, so I built in API transcription switch if the local model is slow.Repo: github.com/pixelsmasher13/pl...
