How Hosiqo compares and tests toolsFinal recommendation
Shortlist Carbon Voice when replacing status meetings and calls with async voice messages that get auto-transcribed and summarized matters most, and StenoAI when generating diarized live transcripts during zoom, teams, or meet calls on a mac matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Open-source desktop app that records, transcribes, and summarizes meetings entirely on-device with no bots, subscriptions, or cloud processing.
Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.

StenoAI (Steno) is an open-source desktop application that records meetings, transcribes them in real time, and generates AI-powered summaries while keeping all data local on the user's device. It positions itself as a privacy-first meeting notes tool with no cloud processing, no subscriptions, and no bots joining calls, and it is distributed under the MIT license with an actively maintained release history (v0.5.4 in June 2026). On Apple Silicon it can use the Parakeet TDT v3 model for live transcription, and it also supports Whisper models, capturing both system audio and microphone input via a native Core Audio Tap on recent macOS versions so it works across platforms like Zoom, Teams, Meet, Discord, and phone calls without OAuth integrations. During recording it shows live speaker labels distinguishing the user from others, and it supports 25 European languages for live transcription with up to 99 languages available via Whisper after recording. Summaries are produced with local LLMs through Ollama (for example Llama 3.2, Gemma, or Qwen), with optional remote Ollama server support to run larger models on a separate machine, and both transcripts and summaries can be exported as editable Markdown. A Windows build is in alpha alongside the primary macOS app. Pricing varies by plan. Check the official website for current pricing.
