How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Bold when recording and summarizing interviews or client calls on mobile 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.
Bot-free AI notetaker by Bold App Studios that records meetings on-device, transcribes with speaker detection, and writes summaries with action items.
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.

Bold (Bold: AI Meeting Note Taker) is an AI meeting assistant from Bold App Studios that records conversations directly on the user's device and then automatically transcribes and summarizes them rather than sending a bot into the call. It offers one-tap recording with real-time transcription, can capture audio in the background whether the screen is on or off, and supports uploading existing audio files for transcription. The app performs speaker detection and diarization across multiple participants, and its AI writes concise summaries that surface action items, decisions, and key insights. Notes are searchable and can be filtered by date, speaker, topic, or keyword, and recordings include replay with smart navigation. Bold supports shareable web links and integrations including Google Meet calendar connection, Notion, Slack, email, and PDF export, with customizable templates for organizing notes. The vendor states the app supports several languages including English, Spanish, French, German, Italian, Portuguese, and Japanese, and offers end-to-end encryption and privacy controls. Bold is available across iPhone, iPad, Mac, and Apple Vision Pro, with a free tier plus premium subscription options, and is actively maintained in 2025/2026. Pricing varies by plan.
