How Hosiqo compares and tests toolsFinal recommendation
Shortlist Basil AI when transcribing confidential client meetings where data must stay on-device matters most, and Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

Celeste AI is a Brazilian voice AI and transcription platform that specializes in Portuguese, particularly Brazilian Portuguese, while also processing audio in additional languages such as English, Spanish, German, Italian, and French. Originally known for automated audio-to-text transcription that the company positions as far more efficient than manual transcription, Celeste AI has expanded into a broader suite that includes a Meeting Assistant (Assistente de Reunião) and AI Notes (Notas de IA), alongside transcription and quality-monitoring offerings. The platform uses machine learning speech models tuned for Portuguese and is offered both as an on-demand service and via an API, so users and businesses can transcribe content as needed. Its on-demand model lets customers pay only for the hours they actually use by purchasing credits, with flexible subscription plans available for those who have recurring transcription needs. As a Brazilian company connected to local institutions such as FGV Ventures and the São José dos Campos technology park, Celeste AI is oriented toward the Brazilian market and Portuguese-language workflows, and it reports a growing user base. The service is currently operating, with a functioning login, demo requests, and support, and is suited to professionals and companies that need accurate Portuguese transcription and meeting documentation. Pricing varies by plan. Check the official website for current pricing.
