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.

Prismical is an open-source AI note taker, from the Amical project, that transcribes meetings, lectures, and voice notes using local AI and without an invasive bot joining the call. It captures system audio in the background and processes it locally with Whisper and Parakeet models, while optionally connecting to cloud providers such as OpenAI, Claude, or Gemini using the user's own API keys. The project is MIT-licensed and actively maintained, with a Prismical Desktop v0.1.0 release in May 2026 and beta mobile apps for iOS and Android. Built with Electron, Next.js, TailwindCSS, and Ollama integration, it provides real-time meeting transcription via system audio capture and a floating widget that shows live transcripts as a conversation happens. Beyond capture, Prismical generates AI-powered summaries and extracts action items, and it keeps notes organized, structured, and searchable with full-text search across captured content. It also exposes an MCP server integration for connecting the tool into broader AI workflows. The combination of bot-free local capture, structured summaries, and free-forever positioning makes it a privacy-oriented alternative to cloud meeting notetakers for individuals who want their recordings to stay on their own devices. Pricing varies by plan. Check the official website for current pricing.
