Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Rimo Voice when multinational teams in japan needing multilingual transcription matters most. Run both through a week of actual calls to see which suits your workflow.

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.

Rimo Voice is an AI transcription and meeting-minutes service developed by Rimo LLC, a Japan-based company, with a strong focus on accurate Japanese-language recognition. It is optimized for Japanese, handling kanji, katakana, punctuation, and specialized or company-specific terminology through dictionary registration, while also supporting more than 30 languages for multinational teams. Rimo Voice can join online meetings through a recording bot across Zoom, Google Meet, Microsoft Teams, and Webex, or transcribe uploaded recordings. It provides real-time, high-precision transcription, automatically generates summaries and suggested next actions, separates statements by speaker, and removes filler words such as "um" and "uh." Teams can collaboratively edit meeting minutes in real time and manage them centrally in shared folders, and the service integrates with CRM systems such as Salesforce and Microsoft Dynamics 365. On security, meeting data is stored within Japan by default (with US or EU storage available on request), and the service holds ISO 27001 and ISO 27017 certifications, with encryption, IP restrictions, and single sign-on. Rimo Voice is best for Japanese organizations and multinational teams operating in Japan that need reliable Japanese transcription and AI-generated minutes. Pricing varies by plan.
