Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Koncert when managers coaching reps from recorded calls and a remote salesfloor matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Koncert is a B2B sales engagement platform built around AI-powered dialing, call recording, and coaching for outbound teams. Its dialer suite includes options such as an AI Parallel Dialer and an AI Flow Dialer that filter voicemails and connect reps to live answers to increase connected conversations and connect rates. Calls are recorded and run through conversation intelligence that scans for objections and other signals so managers can coach reps at scale, and a remote Salesfloor gives managers a virtual workspace for real-time coaching during calls. Koncert also includes a multi-channel cadence sequencer spanning phone, email, video, text, and social, plus caller ID management that selects local numbers and monitors number health. For practice and training, Koncert offers AI PitchLab, an add-on where reps rehearse pitches against AI-powered buyer personas without the pressure of a live prospect, with objection-handling practice and automatic transcription and scoring of performance. Together these capabilities target outbound sales teams, SDRs, and managers who want dialing, real-call analysis, and structured roleplay practice within one platform. Pricing varies by plan. Check the official website for current pricing.
