How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Polar Notes when converting youtube videos, slides, and pdfs into a study pack matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

Polar Notes (PolarNotes AI) is an AI note-taking tool built for students and teachers that converts lectures and course materials into organized study resources. Users can record or upload a lecture, paste a YouTube link, or import slides and PDFs, and the app automatically transcribes audio when needed and analyzes the content to produce summarized notes, key concepts, section headings, and short overviews. From the same source material it can generate a study pack that includes study guides, flashcards, and assessment questions, and results can be exported to Google Docs or PDF with study sets organized in one place. Polar Notes emphasizes privacy and offline access on iOS, keeping notes stored locally on the device unless the user chooses to back them up or share them, which lets students review notes without an internet connection. It also supports multilingual transcription, making it usable for international students and teachers recording in different languages. The tool is delivered as an iOS app with an accompanying web experience and free online tools, and is aimed at learners who want lecture and document content distilled into exam-ready study material rather than verbatim meeting records. Pricing varies by plan. Check the official website for current pricing.
