Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and SubEasy when generating multilingual subtitles and captions for videos and social media content 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.

SubEasy is an AI-powered transcription and subtitling platform that converts audio and video files into accurate text transcripts and styled, animated captions. Users can upload media or paste a YouTube or TikTok link, and the tool produces both subtitle and transcript views with speaker identification, precise timecodes, and filler-word removal. It supports over 100 languages and offers context-aware translation, AI dubbing with voice swapping, and video OCR for hardcoded subtitles. Beyond raw transcription, its AI Companion turns transcripts into summaries, detailed notes, meeting minutes, and repurposed content such as blog posts, and lets users query the transcript through an "Ask ChatGPT" interface to pull out insights. An AI refine-and-correct tool fixes grammar and recognition errors. SubEasy is aimed at content creators, podcasters, educators, researchers, marketing teams, and corporate users who need multilingual transcription, captioning, and quick conversation summaries. It runs on a freemium model with a small number of free daily transcripts and paid tiers unlocking unlimited transcription and exports.
