Shortlist VITO when reviewing and searching the content of past phone calls matters most, and joinly when self-hosted, privacy-first real-time meeting transcription for regulated teams matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

joinly is an open-source middleware project (by joinly-ai) that makes meetings accessible to AI agents. It runs as a Model Context Protocol (MCP) server that equips any agent with the tools to join a live video call, capture a real-time transcript, and interact by voice or chat during the meeting. Rather than being a finished notetaker app, joinly is a framework developers use to build interactive meeting agents that can listen, answer, search the web, draft documents, and post chat messages while the meeting is in progress. It works cross-platform across Google Meet, Zoom, and Microsoft Teams (and browser-based calls), and is model-agnostic, supporting OpenAI, Anthropic, and local models through Ollama. Speech-to-text and text-to-speech are modular, with Whisper or Deepgram for transcription and Kokoro, ElevenLabs, or Deepgram for synthesis. The project is MIT licensed and deployed via Docker (with a separate CUDA GPU image), giving teams full data sovereignty. The MCP server exposes join/leave controls, transcript and participant access, audio control, chat messaging, and video snapshots, making it a building block for custom, privacy-first meeting automation. Pricing varies by plan. Check the official website for current pricing.
