Brazilian Portuguese-focused AI voice and transcription platform offering on-demand transcription plus a meeting assistant and AI notes, with credit-based and subscription plans.
Speech-to-text and voice AI provider offering real-time transcription and live captioning APIs.
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.

Speechmatics is a speech-to-text and voice AI company that provides transcription and captioning technology through APIs, supporting both recorded and real-time audio across many languages. Its core offering converts speech to text for multilingual, multi-speaker conversations, with low-latency real-time processing suitable for live use. The platform powers live captioning for events, sports, news, and broadcasts, and its transcription technology can be embedded into other products, including meeting platforms that need automated note-taking and captions. Because Speechmatics is delivered primarily as a developer-facing engine, it serves teams building their own applications as well as media and enterprise customers who need accurate speech recognition at scale. It supports features such as multi-speaker handling and broad language coverage, and the company emphasizes security and compliance certifications. Speechmatics is aimed at developers, product teams, media organizations, and enterprises that need to add accurate transcription, subtitles, or live captions to their own workflows and applications rather than use a packaged consumer note-taker. Pricing varies by plan. Check the official website for current pricing.
