How Hosiqo compares and tests toolsFinal recommendation
Shortlist Basil AI when transcribing confidential client meetings where data must stay on-device matters most, and Carbon Voice when capturing spoken ideas and turning them into structured documents, emails, or action items matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Basil AI (Basil Private AI Note Taker) is a privacy-first AI transcription and note-taking application that processes all audio locally on Apple devices using Apple's on-device speech and machine-learning frameworks. Because recordings, transcripts, and summaries never leave the device and no cloud servers are involved, Basil is positioned for privacy-conscious professionals handling sensitive conversations, including lawyers conducting client meetings and other client-services practitioners where confidentiality matters. The app records live meetings and can also process uploaded audio and DRM-free video files, then generates transcripts with speaker diarization plus AI summaries and key takeaways. It supports a large set of languages and can work offline, including in airplane mode. Outputs can be exported to formats such as text, PDF, CSV, and JSON, and integrated with Apple's ecosystem (Apple Notes, iCloud Drive, Files). Basil is distributed on the Apple App Store by TONSOR LLC and is available as a universal app across iPhone, iPad, Mac, and Apple Vision, with recent iOS, iPadOS, macOS, and visionOS versions required. Pricing varies by plan. Check the official website for current pricing.

Carbon Voice is an asynchronous voice-messaging and voice-notes app for iOS, Android, Web, and Apple Watch. Users record voice memos or messages with a single keystroke or swipe, and every message is automatically transcribed so it can be read, searched, labeled, and organized. The app is built around reducing real-time meetings and calls: instead of scheduling synchronous time, teammates exchange voice messages that the recipient can catch up on later. Layered on top is a large library of AI actions that turn raw voice into structured content — bulleted summaries, cleaned-up transcripts (removing filler words and fixing grammar), meeting notes, agendas, action items, professional emails, and longer documents such as PRDs and reports. Users can also query an AI assistant about any chat. A Global Voice feature can translate messages between languages, and messages can be sent to people who don't have the app via a secure email link. It is aimed at distributed teams, managers, and individuals who prefer talking over typing.
