How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and Handy when privacy-sensitive voice-to-text where audio must stay on-device matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Callabo (콜라보) is an AI meeting assistant developed by Return Zero (리턴제로), a Korean speech-AI company. It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup. Callabo connects to online meetings on Google Meet, Microsoft Teams, Zoom, and Webex, and also supports recording in-person meetings. After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification. Mobile apps are available for both iOS and Android. Pricing varies by plan. Check the official website for current pricing.
Best suited for
Handy is a free, open-source desktop application that turns your voice into text completely offline, with no audio ever leaving your computer. You press a configurable keyboard shortcut, speak, and release (push-to-talk), or use a toggle mode to start and stop; Handy transcribes what you said and automatically pastes the result into whatever text field is active. Because it runs entirely on-device, it is built for privacy-conscious users who want dictation without cloud uploads or subscriptions. Under the hood it is built with Tauri (a Rust backend with a React/TypeScript frontend) and supports multiple local speech-recognition models, including OpenAI's Whisper variants with GPU acceleration and the CPU-friendly Parakeet V3 model with automatic language detection. Silero Voice Activity Detection filters out silence so only speech is processed. Handy runs on macOS (Intel and Apple Silicon), Windows, and Linux, and is released under the MIT license. It positions itself as an accessible, extensible alternative to paid dictation tools, and is best suited for hands-free typing rather than recording multi-party meetings.
