Murmur is a private, voice-first personal operating system positioned as a voice journaling tool, serving high-agency thinkers. Its core idea is that "speaking is better than typing," allowing users to capture ideas at the speed of speech, with an intelligent system automatically organizing them.
In terms of purpose, Murmur is used to replace traditional typed notes and ordinary voice memo apps. Traditional voice memos save audio files that cannot be searched and are easily lost; Murmur, by contrast, turns every spoken idea into a 1536-dimensional semantic vector embedding, making the content queryable in natural language and precisely recallable.
The main capabilities include:
- Capture: Record voice through a single gesture of "press and hold -> speak -> release," with less than 100 milliseconds of haptic latency, a subpixel-level real-time waveform, and a swipe-up continuous lock feature.
- Ask My Mind: Perform semantic vector search across lifelong memos, allowing users to query in natural language and jump directly to verified timestamped audio references.
- Action Engine: A single cognitive parse produces tasks with due dates, decisions, ideas, and time-locked "future capsules," with no need for manual tagging or organizing.
- Multilingual support: Powered by OpenAI Whisper and multilingual neural speech models, it can capture English, Hindi, Bengali, Urdu, and code-switched bilingual speech (such as Hinglish), with contextual formatting and punctuation.
In terms of usage, users record through a single gesture, and after releasing, the system automatically completes transcription, semantic embedding, and structured extraction. When querying, users ask questions in natural language, and results can jump to the original audio timestamp. The product emphasizes that there is no chatbot, only vector recall and rapid capture.
Applicable scenarios include: recording personal ideas, task management, decision tracking, inspiration collection, and scenarios that require quickly capturing and retrieving personal thoughts by voice over the long term. The product explicitly states that it is aimed at high-agency thinkers.
In terms of limitations and privacy: Murmur is a strictly private, offline-first personal journal, with no social feed, public following graph, likes, or performative algorithms. Voice recordings belong solely to the user and are protected with enterprise-grade encryption. It is currently available only for Android, downloadable through Google Play, or available through early access on the web.
