How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Klu when teams that want meeting follow-ups auto-assigned and routed into slack or notion matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

Klu (klu.so) is an AI meeting assistant that positions itself as a meeting automation platform for modern teams rather than a transcription-only tool. It captures meetings through a browser extension that can auto-join calls, a Mac desktop app, and offline capture for in-person conversations. During and after a meeting, Klu produces a transcript with speaker recognition, generates bullet-point summaries, surfaces action items, and supports custom note sections, alongside a smart-search and Ask AI capability for retrieving details from past conversations. A Deep Dive feature lets users ask questions that span multiple meetings, such as what was committed to with a particular account over a period of time. On the workflow side, Klu detects follow-ups, assigns them to owners with deadlines, and can push them into tools like Slack and Notion. For CRM users, Klu logs meeting outcomes to HubSpot, Salesforce, and Pipedrive on the relevant record, and connects to additional CRMs such as Attio and Affinity through Zapier, helping keep deals and accounts current without manual data entry. It maintains comparison pages against established notetakers and supports multilingual transcription. Pricing varies by plan. Check the official website for current pricing.
