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 Gladia when adding live captions and transcripts to video-conferencing products matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Developer-focused speech-to-text API with real-time and async transcription, diarization, and meeting-bot integrations.
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.

Gladia is a speech-to-text API built for developers and product teams who want to embed transcription and audio intelligence into their own applications, including meeting assistants and note-taking tools. It offers both asynchronous transcription of pre-recorded audio and video files and a real-time streaming engine over WebSocket that returns results with low latency, making it suitable for live meetings and calls. The platform handles a wide range of languages with automatic language detection and code-switching, so it can follow conversations where participants switch languages mid-call. For meeting use cases, Gladia provides speaker diarization to label who said what, word-level timestamps, custom vocabulary, and audio-intelligence features such as summarization, sentiment analysis, and action-item extraction. It also offers meeting-bot integration that can join Zoom, Google Meet, and Microsoft Teams sessions to capture audio. Gladia positions itself as infrastructure rather than an end-user product, so companies typically use it to power their own transcription, captioning, or conversation-analytics features while relying on Gladia's compliance posture for data handling. Pricing varies by plan. Check the official website for current pricing.
