How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and VoiceInk when dictating prompts and code comments into ai chat tools and editors 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.

VoiceInk is a native macOS dictation application that converts spoken words into text and inserts them into any app, positioned as an open-source alternative to Superwhisper and Wispr Flow. It runs transcription locally using whisper.cpp Whisper models (and Parakeet via FluidAudio), so voice data stays on the device by default; optionally, you can connect cloud transcription and AI services such as Groq, Deepgram, Cerebras, and Gemini using your own API keys. Users trigger recording with global keyboard shortcuts or push-to-talk, and VoiceInk types the result wherever the cursor sits. Its Power Mode automatically switches transcription and AI-enhancement settings based on the active app or website, while a Personal Dictionary handles custom terminology and text replacements. Enhancement prompts can reformat dictation for email, chat, or social posts, and a later release added the ability to share audio files into the app for transcription. The project is published on GitHub under GPL v3, runs on Apple Silicon Macs (macOS 14.4+), and also offers an iOS version. It suits writers, developers, and professionals who want fast, private hands-free text entry.
