How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and CaseMark when litigation teams turning hearing and deposition recordings into structured summaries and chronologies matters most. Try them side by side on real calls before deciding — needs vary by team.

CaseMark is an AI legal operating system whose court-reporting product processes uploaded deposition and proceeding recordings into reviewed transcripts and structured summaries for law firms and court reporters.
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.
Best suited for
CaseMark is an AI-powered legal operating system built for attorneys, law firms, and court-reporting providers. Within its court-reporting product, users upload audio or video recordings of depositions, hearings, and proceedings (up to 8GB per file), then review AI transcript drafts alongside the source media, verify terminology, and certify final transcripts. The platform does not record live proceedings or employ stenographers; it works from existing media files attached to a matter. Beyond transcription review, CaseMark generates structured work product from transcripts and documents, including deposition summaries (page-line, narrative, and analysis formats), proceeding recaps, indices, case summaries, and medical chronologies. Everything is organized around individual matters, with a branded client portal for secure delivery and matter-scoped chat. CaseMark is web-based (app.casemark.com) and exposes services through its case.dev API platform. It is SOC 2 Type II certified and HIPAA compliant, and states it does not use customer data for training. It targets court reporters, litigation teams, and corporate legal departments.
