How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Vizard when converting zoom or other recorded meetings into transcripts and shareable clips matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Vizard is an AI video tool that transcribes audio and video into searchable, editable text in 30+ languages while automatically detecting highlights and turning long recordings into short clips.
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.

Vizard is a multimodal AI video platform whose transcription engine converts uploaded audio and video into searchable, editable text. Users can transcribe files from their computer, paste a YouTube link, or import Zoom recordings, then read and edit the result like a document. The tool supports 30+ languages including English, Spanish, French, German, Japanese, Korean, Mandarin, Portuguese, Hindi, and Arabic, and lets users export transcripts as .SRT or .TXT files. Beyond plain transcription, Vizard analyzes the recording to identify key moments and highlights, auto-generate captions and subtitles, and produce short, social-ready clips with smart titles. Its transcript-based editor lets you trim footage, cut bad takes, and remove silences simply by deleting words. Vizard is aimed primarily at content creators, podcasters, marketers, coaches, and agencies who repurpose long-form video, but the transcription and Zoom-import features also serve anyone needing voice-to-text. It offers a team workspace for collaboration, brand templates, and caption translation into many additional languages.
