Shortlist Castmagic when transcribing podcast episodes and generating show notes and summaries matters most, and Trellus when increasing connect rates with a parallel dialer matters most. Try them side by side on real calls before deciding — needs vary by team.

Real-time AI sales coaching and parallel dialer delivered as a lightweight Chrome extension that layers onto existing sales tools.
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.

Trellus is a real-time AI sales coaching and dialing tool delivered primarily as a lightweight Chrome extension that layers on top of existing sales engagement platforms such as Salesloft, Outreach, and HubSpot. Its real-time coaching analyzes call audio during live conversations to detect intent and signals and provides adaptive guidance, nudging reps to adjust pacing, listen more, or change approach as the conversation unfolds. Alongside live coaching, Trellus offers a parallel dialer that lets reps dial multiple lines at once to increase connect rates, with automated voicemail drops and number-health monitoring. The platform also includes AI voice agents that can handle inbound qualification or act as practice prospects for rep training, plus call analytics and performance scoring so managers can review conversations after the fact. A sales floor feature supports team collaboration. Because it runs as a browser extension on top of tools reps already use, Trellus is designed to add live guidance and faster dialing without requiring teams to migrate to a separate platform. It is aimed at sales development reps, account executives, and sales leaders focused on outbound calling performance. Pricing varies by plan. Check the official website for current pricing.
