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.

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.

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.

Proactor AI, published by PROACTORAI LIMITED, is an AI note-taking and voice-recording application that captures meetings, lectures, interviews, and personal voice memos and converts speech to text in real time. As a recording runs, it analyzes the conversation and surfaces summaries, key insights, and suggestions, then organizes the resulting notes by speaker and topic. A notable aspect of Proactor is its task orientation: it can automatically turn discussion into action items, including assigning owners and due dates, so that spoken conversations become trackable outcomes rather than static transcripts. The app retains context across sessions so it can reference earlier conversations, and it lets users export notes in formats such as PDF, Word, Markdown, and plain text. It supports transcription in multiple languages and can double as a general-purpose voice recorder for journaling, ideas, and quick memos. Proactor is aimed at professionals and teams who want both meeting documentation and follow-up task management, and it syncs notes across iOS, iPad, Android, and the web. Pricing varies by plan. Check the official website for current pricing.
