How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and Whisperstream when transcribing imported audio recordings privately on-device matters most. Try them side by side on real calls before deciding — needs vary by team.

Whisperstream is a privacy-focused Windows dictation app that turns speech into text entirely on-device, with no cloud upload.
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.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
