Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Trellus when increasing connect rates with a parallel dialer matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Real-time AI sales coaching and parallel dialer delivered as a lightweight Chrome extension that layers onto existing sales tools.
Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. 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.
