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.

Ma Synthèse is a French SaaS application from GetCaaS that automates meeting documentation through a three-step process: it captures and transcribes spoken exchanges, organizes the discussion by topic and by speaker, then generates a clear, structured meeting report. Each report surfaces decisions and important points and produces an action list assigned to individual participants, with the tool able to send those tasks out and remind people who forget them. Its defining angle is data sovereignty: the service runs on French infrastructure (Scaleway) using Mistral AI, keeps data in France, and is positioned as a GDPR-compliant alternative for organizations with strict confidentiality needs. It targets municipal councils, public bodies and law enforcement, as well as legal and medical professionals. Pricing is usage-based, calculated from meeting hours multiplied by the number of licenses, with one free hour per month per organization and no commitment; organizations above thirty licenses get a custom quote. Announced in June 2026, it was selected to present at VivaTech 2026.
