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.

Gladia is a speech-to-text API built for developers and product teams who want to embed transcription and audio intelligence into their own applications, including meeting assistants and note-taking tools. It offers both asynchronous transcription of pre-recorded audio and video files and a real-time streaming engine over WebSocket that returns results with low latency, making it suitable for live meetings and calls. The platform handles a wide range of languages with automatic language detection and code-switching, so it can follow conversations where participants switch languages mid-call. For meeting use cases, Gladia provides speaker diarization to label who said what, word-level timestamps, custom vocabulary, and audio-intelligence features such as summarization, sentiment analysis, and action-item extraction. It also offers meeting-bot integration that can join Zoom, Google Meet, and Microsoft Teams sessions to capture audio. Gladia positions itself as infrastructure rather than an end-user product, so companies typically use it to power their own transcription, captioning, or conversation-analytics features while relying on Gladia's compliance posture for data handling. Pricing varies by plan. Check the official website for current pricing.
