Shortlist Aiko when transcribing recorded lectures into searchable text for studying matters most, and Nimitai when preparing reps with research and briefings before customer meetings matters most. Run both through a week of actual calls to see which suits your workflow.

Aiko is a native transcription app for macOS, iOS, and visionOS, developed by Sindre Sorhus, that converts speech to text from meetings, lectures, and recordings entirely on-device. It uses OpenAI's Whisper model running locally, so audio never leaves the user's device, which makes it appealing for students and professionals with privacy requirements. Aiko transcribes both audio and video files in common formats such as .m4a, .wav, .mp3, .mp4, and .mov, and supports around 100 languages. Transcriptions can be exported in multiple formats, including JSON, CSV, and SRT subtitles, and the app includes a word-replacement feature to automatically correct recurring errors. It also integrates with Apple Shortcuts for automation workflows. Because Aiko prioritizes accuracy over speed, it does not perform live transcription while recording and currently does not include speaker detection, so it is best for transcribing recorded lectures, interviews, and meetings after the fact. The app is offered as a Universal Purchase with a free trial via TestFlight, making it a low-cost, privacy-first option for turning lecture and meeting recordings into searchable text. Pricing varies by plan. Check the official website for current pricing.

Nimitai is an AI meeting-intelligence and conversation-analytics platform built specifically for B2B sales teams at startups and growth-stage companies. It is structured around specialized functions: a research step that pulls prospect intelligence before a call, a preparation step that generates pre-call briefings with talking points and deal context, and a live copilot that delivers real-time coaching during the meeting. Nimitai captures calls through a lightweight Chrome extension that works with Zoom, Google Meet, and Microsoft Teams without requiring a separate bot to join the call. During a live conversation it records and analyzes audio and engagement signals, surfaces coaching cues, flags unaddressed objections, detects shifts in buyer interest, and highlights deal-risk signals so reps can adjust in the moment. After the call it generates structured scorecards and call summaries and can sync them to CRMs such as Salesforce, HubSpot, and Pipedrive, reducing manual data entry. It is aimed at sales organizations that want both real-time selling assistance and post-call analytics in a single tool, positioned as an option for smaller revenue teams. The platform is operating and accepting B2B sales teams. Pricing varies by plan. Check the official website for current pricing.
