Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Efficlose when auto-joining and transcribing scheduled zoom, teams, or meet meetings matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

An AI meeting platform offering a bot-free Chrome extension plus desktop and web apps that transcribe, summarize, and extract action items from calls.
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.

Efficlose is an AI meeting platform that captures, transcribes, and summarizes conversations through a combination of a Chrome extension, a desktop app, and a web platform. Its Chrome extension is positioned as a way to record meetings without a bot joining the call, capturing audio locally in the browser so no extra participant is announced or shown in the meeting; users can choose to capture a single tab, a specific window, or the full screen, and start or stop recording manually rather than relying on calendar triggers. For users who prefer automated joining, the desktop app and platform can connect to a calendar and send a bot to scheduled meetings on Zoom, Microsoft Teams, and Google Meet. Recordings are transcribed automatically with speaker identification, and the platform generates summaries with key decisions, next steps, and assigned action items. It also offers meeting search across past recordings and an AI assistant for querying conversations, plus integrations with business tools such as Salesforce, HubSpot, Slack, and Notion. Efficlose is aimed at teams across sales, customer success, recruiting, engineering, and project management who want flexible recording options and structured meeting outputs synced into their existing tools. Pricing varies by plan. Check the official website for current pricing.
