How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and VITO when capturing and sharing business call details for agents, sales, and small-business owners matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. 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.
