How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products 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.
Attendee is an open-source REST API, developed by Attendee Labs, that abstracts the engineering work of building meeting bots into a single developer-friendly interface. Instead of maintaining separate bot stacks for each video platform, developers send one API request and Attendee dispatches a bot that joins a Zoom, Google Meet, or Microsoft Teams call, then returns recordings, transcripts, and real-time media streams. It is built on widely used, battle-tested technologies such as Django, PostgreSQL, and Redis, and is designed to run from a single Docker image so teams can self-host it on their own infrastructure for data residency, compliance, and cost control. The project documents real-time transcription, webhooks, calendar integration, scheduled meetings, and websocket audio input/output. Because it is open source and self-hosted, organizations in regulated industries can keep meeting audio and transcripts inside their own environment rather than routing them through a third-party vendor. The repository is actively maintained with frequent releases, and the project markets itself as a lower-cost alternative to closed-source meeting-bot platforms for developers who want to embed meeting capture and transcription into their own applications. Pricing varies by plan. Check the official website for current pricing.

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.
