How Hosiqo compares and tests toolsFinal recommendation
Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and PodSpin when podcast agencies and networks repurposing episodes into blogs, newsletters, and social content at scale matters most. Try them side by side on real calls before deciding — needs vary by team.

PodSpin is an AI tool that transcribes a podcast episode and repurposes it into show notes, blog posts, social posts, captioned video clips, and newsletters.
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.

PodSpin is an AI podcast repurposing platform that turns a single episode into a full content suite. Users upload an audio or video file, paste a YouTube URL, or connect an RSS feed, and the AI transcribes the recording with automatic speaker diarization, paragraph- and word-level timestamps, and multi-language detection across 90+ languages. From that transcript it generates blog posts, show notes, chapter markers, episode descriptions, SEO keywords, newsletters, platform-specific social posts, and short vertical video clips with animated captions, with each clip assigned a virality score. A built-in editor lets users correct the transcript before publishing, and transcripts export to formats including SRT, VTT, TXT, DOCX, PDF, and JSON. It is aimed at solo podcasters, podcast agencies, and networks who want to reduce manual content production. Its distinguishing angle is processing the whole content set in parallel rather than sequentially, so a roughly hour-long episode is handled in a few minutes, positioned as a lower-cost alternative to tools like Podsqueeze, Castmagic, and Descript.
