How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Strella when b2b and b2c qualitative studies with built-in recruitment 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.

Strella is an AI-powered customer research platform designed to run in-depth interviews and generate actionable insights in hours rather than weeks. Teams create a study in minutes using AI-generated, unbiased discussion guides that any team member can refine and launch, and they can either lead interviews themselves or hand moderation to Strella's AI moderator for faster results. During AI-moderated sessions, the platform conducts the conversation and adapts questions in real time based on each participant's responses, asking thoughtful follow-up questions to explore topics more deeply. Strella handles study logistics including recruitment, incentives, and scheduling, and offers a choice between interviewing customers a team already knows or recruiting from a panel of millions of global participants with targeting across professional, demographic, and behavioral segments; it supports research in dozens of languages for both B2B and B2C studies. On the analysis side, the platform synthesizes findings in real time, identifies themes across participants and segments, and lets researchers chat with their research to generate video highlight reels and pull insights at multiple levels, from an individual participant up to broader strategic patterns. The company is venture-backed and reports use by recognized consumer brands. Pricing varies by plan. Check the official website for current pricing.
