How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and StenoAI when generating diarized live transcripts during zoom, teams, or meet calls on a mac matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

StenoAI (Steno) is an open-source desktop application that records meetings, transcribes them in real time, and generates AI-powered summaries while keeping all data local on the user's device. It positions itself as a privacy-first meeting notes tool with no cloud processing, no subscriptions, and no bots joining calls, and it is distributed under the MIT license with an actively maintained release history (v0.5.4 in June 2026). On Apple Silicon it can use the Parakeet TDT v3 model for live transcription, and it also supports Whisper models, capturing both system audio and microphone input via a native Core Audio Tap on recent macOS versions so it works across platforms like Zoom, Teams, Meet, Discord, and phone calls without OAuth integrations. During recording it shows live speaker labels distinguishing the user from others, and it supports 25 European languages for live transcription with up to 99 languages available via Whisper after recording. Summaries are produced with local LLMs through Ollama (for example Llama 3.2, Gemma, or Qwen), with optional remote Ollama server support to run larger models on a separate machine, and both transcripts and summaries can be exported as editable Markdown. A Windows build is in alpha alongside the primary macOS app. Pricing varies by plan. Check the official website for current pricing.
