How Hosiqo compares and tests toolsFinal recommendation
Shortlist Attendee when developers embedding meeting recording and transcription into their own saas products matters most, and VITO when capturing and sharing business call details for agents, sales, and small-business owners matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

VITO (비토) is a call-transcription app developed by ReturnZero Inc. (리턴제로), a Seoul-based speech-AI company. It automatically converts recorded phone calls into readable, chat-style text using ReturnZero's proprietary speech-recognition engine tuned for conversational Korean. Rather than joining live virtual meetings as a bot, VITO works from a phone's call-recording function: once a call is recorded, the audio is transcribed, with speaker identification distinguishing participants, and users can later read, keyword-search, replay specific segments, and review summaries of past conversations. It also supports bulk conversion of previously recorded calls. VITO is available on iOS and Android, with PC/web access to view transcripts, and offers cloud storage so call history is preserved across devices. The company also exposes its underlying RTZR speech-to-text technology as a separate developer API. VITO is aimed at everyday users and professionals such as real-estate agents, delivery drivers, office workers, students, and small-business owners who need to revisit, search, or share the content of their phone conversations.
