How Hosiqo compares and tests toolsFinal recommendation
Shortlist Castmagic when transcribing podcast episodes and generating show notes and summaries matters most, and Ma Synthèse when documenting internal team meetings with auto-assigned tasks and reminders matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Castmagic is an AI-powered content platform that transforms recorded audio and video into transcripts and a range of derived content. After a file is uploaded or imported, Castmagic transcribes it with speaker diarization and then automatically generates summaries, show notes, timestamps, titles, social media posts, newsletters, and other assets from the same recording. The platform integrates with sources including YouTube, Apple Podcasts, Google Drive, and Zoom, so recorded meetings and interviews can flow directly into a workspace for processing alongside podcast episodes. Castmagic includes semantic search across a media library, brand-voice customization, reusable templates, and commenting and approval workflows aimed at teams and agencies that manage content for multiple brands. While its marketing centers on podcasters and creators, the transcription, speaker labeling, and summary features make it applicable to meeting and interview recordings as well. It is intended for content teams, marketing agencies, podcasters, coaches, and sales organizations that want to convert recorded conversations into transcripts and repurposed written content rather than only a raw transcript. Pricing varies by plan. Check the official website for current pricing.

Ma Synthèse is a French SaaS application from GetCaaS that automates meeting documentation through a three-step process: it captures and transcribes spoken exchanges, organizes the discussion by topic and by speaker, then generates a clear, structured meeting report. Each report surfaces decisions and important points and produces an action list assigned to individual participants, with the tool able to send those tasks out and remind people who forget them. Its defining angle is data sovereignty: the service runs on French infrastructure (Scaleway) using Mistral AI, keeps data in France, and is positioned as a GDPR-compliant alternative for organizations with strict confidentiality needs. It targets municipal councils, public bodies and law enforcement, as well as legal and medical professionals. Pricing is usage-based, calculated from meeting hours multiplied by the number of licenses, with one free hour per month per organization and no commitment; organizations above thirty licenses get a custom quote. Announced in June 2026, it was selected to present at VivaTech 2026.
