Whisper is an open-source (MIT) Obsidian community plugin by nikdanilov for speech-to-text. You record audio from the sidebar mic (or Alt+Q), upload audio files, or right-click an audio file in your vault, and it transcribes via the Whisper API and inserts the text into your notes. Transcription works with OpenAI, Groq, Azure, or any Whisper-compatible API; the user supplies their own API key and can override the endpoint URL in settings (the code exposes apiKey/openAiApiKey fields and a configurable apiUrl defaulting to https://api.openai.com/v1/audio/transcriptions). Optional LLM post-processing (fix grammar, remove filler words, format as markdown, extract action items) supports Claude and GPT plus any OpenAI-compatible endpoint such as Ollama or LM Studio, again via a user-provided key (anthropicApiKey/postProcessingApiKey + postProcessingUrl). Runs on Obsidian desktop and mobile. Roughly 48.8k downloads and well-maintained (latest v1.9.1, last commit April 2026, 66 of 71 issues closed). It is a client plugin only; all provider costs are billed to the user's own accounts.
