Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Microsoft Teams Copilot when catching up on a teams meeting you joined late or missed matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Copilot in Microsoft Teams is the AI meeting assistant built into Microsoft 365 Copilot. During or after a Teams meeting it summarizes key discussion points (including who spoke and what they said), suggests action items, and answers questions by reasoning over the conversation and meeting chat. It works in real time via the Copilot button and is also available afterward through the meeting chat and Recap tab. Transcription does not have to be running just to turn Copilot on during a meeting, but live transcription must be enabled to prompt Copilot about what was said and to access its conversation history after the meeting ends; recording itself is not required. Longer responses can be opened in Word, and table-style output in Excel. Copilot is sold as a paid add-on that requires a qualifying Microsoft 365 or Office 365 subscription, and it extends beyond Teams across Word, Excel, Outlook, and other Microsoft 365 apps. A no-cost Microsoft 365 Copilot Chat tier is included for eligible subscribers but excludes the full work-grounded Teams meeting Copilot experience.
