Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and SRTGen when transcribing corporate meetings, conferences, and recorded interviews matters most. Test each on your own meetings; the right choice tends to become obvious quickly.
On-device AI transcription app for Mac, iOS, and visionOS that converts lecture and meeting audio to text privately.
AI subtitle and SRT generator that also transcribes meetings, interviews, and podcasts with multi-format caption export.
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.

SRTGen is an AI-powered subtitle and transcription platform centered on producing professional caption files. Users can upload video or audio, or paste links from social platforms, and SRTGen generates time-coded subtitles with automatic speaker separation. While it is marketed heavily toward creating SRT files and translated subtitles for content like YouTube and short-form video, the platform explicitly extends to corporate meetings, conferences and events, and academic and market research, including interviews and focus groups. It supports a large number of languages and locales with global dialect coverage and offers translation alongside transcription. Output options include subtitle formats such as SRT, VTT, and ASS, as well as document and data formats like DOCX, PDF, TXT, and JSON. SRGen includes a timeline-based subtitle editor with animation capabilities, the ability to burn hardcoded subtitles into video, and real-time multi-user collaboration. The service runs on a credits-based model rather than a fixed subscription, with a small free allotment to start, making it flexible for occasional caption jobs as well as recurring meeting and interview transcription needs across teams and organizations. Pricing varies by plan. Check the official website for current pricing.
