How Hosiqo compares and tests toolsFinal recommendation
Shortlist Callabo when turning recurring internal team meetings into shareable summaries and action items matters most, and VidNotes when professionals extracting action items and decisions from zoom, meet, or teams recordings matters most. Try them side by side on real calls before deciding — needs vary by team.

VidNotes is an AI-powered transcription and note-taking tool that turns videos, lectures, podcasts, and meeting recordings into structured, searchable text. Users either upload a local file (MP4, MOV, MKV, and more) or paste a link from YouTube, TikTok, Instagram, or Vimeo, including exported recordings from Zoom, Google Meet, Microsoft Teams, and webinars. Under the hood it runs the audio through OpenAI's Whisper model for speech-to-text, then a large language model produces a summary, key points, timestamped notes, auto-generated flashcards, and extracted action items in the same language as the source. A chat feature lets users ask questions about the content and receive answers with citations, and transcripts and notes can be exported as TXT, PDF, Markdown, or SRT captions. It supports English plus 30+ additional languages and handles mixed languages and varied accents. Aimed at students, researchers, content creators, and professionals, VidNotes is available in the browser, as a Chrome extension, and as iOS and Android apps. The app is published by Silpho LLC.
