Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and Otolio when sales teams preparing for and following up on client meetings matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Japanese AI meeting-minutes service (formerly Smart Scribe) that transcribes and automates the full minutes workflow for businesses.
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.

Otolio, formerly known as Smart Scribe (スマート書記), is a Japanese AI meeting-minutes service operated by Epicbase, Inc. It is designed for corporate use and automates the entire meeting documentation process rather than only producing a transcript. Users can record in-person meetings or capture audio from web conferencing tools, after which Otolio automatically transcribes the audio and generates summarized, cleaned-up minutes. Features include speaker visualization, registration of specialized terminology for improved accuracy on industry-specific vocabulary, and filler-word removal. The platform organizes recording, transcription, minutes generation, and follow-up tasks within a single interface, and offers specialized agents oriented toward meeting minutes and toward sales preparation and follow-up. Security is positioned as a core concern for Japanese enterprises: Otolio is ISO 27001 certified, uses encryption, and states that it does not perform unauthorized machine learning on user data. A mobile app supports transcription, audio playback, and file upload. Otolio is aimed at Japanese organizations that hold frequent internal meetings, sales calls, one-on-ones, and executive sessions and want to reduce the administrative burden of writing minutes. Pricing varies by plan. Check the official website for current pricing.
