How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and TwinMind when users who prefer a bot-free, privacy-conscious notetaker over tools that join the meeting matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.
macOS-native AI meeting assistant that records and transcribes calls locally with built-in Whisper and Parakeet models, no bots required.
Browser-extension and mobile AI meeting assistant that transcribes calls in real time on-device and turns them into searchable notes.
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.

TwinMind is an AI meeting assistant delivered as a Chrome browser extension and companion mobile app that captures, transcribes, and summarizes conversations from video calls and in-person meetings. The Chrome extension works alongside Google Meet, Zoom, and Microsoft Teams to produce real-time transcripts and then generate structured notes and action items after the call. Rather than sending a separate bot participant into the meeting, TwinMind transcribes the audio playing on the user's device, so there is no visible 'recording bot' announcement. The company emphasizes a privacy-first design: the product states that audio is not stored and that only text transcripts are kept, with data saved locally and optional encrypted cloud backup. TwinMind supports a large set of languages and lets users query their past conversations through an AI chat interface, positioning itself as a personal 'second brain' for recall. It markets a single experience spanning desktop browser and phone so meetings, voice notes, and ambient conversations can be captured in one place. The product is actively maintained and operating in 2025-2026. Pricing varies by plan. Check the official website for current pricing.
