Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and StreamText when real-time captioning and translation in classrooms and lectures for accessibility matters most. Run both through a week of actual calls to see which suits your workflow.

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.

StreamText is an enterprise real-time captioning platform, founded in 2003, that delivers spoken words as live captions to web pages, devices, and conferencing tools. It supports two modes: professional human captioners (using stenography, re-speaking, and text interpreting) and AI-powered automatic speech recognition (ASR), which converts speech to text in real time and produces captions, translations, and transcripts. Source audio is captioned live and streamed to an ADA-compliant viewer that works with screen readers, while AI captioning recognizes around 20 source languages and offers realtime translation into well over 100 languages. Captioned sessions can be exported as timed-text transcript files such as .srt and .vtt, and StreamCast lets organizers overlay captions onto videos and presentations. It integrates with Zoom, Webex, YouTube, and Adobe, and exposes a full API for OEM and third-party embedding. It is aimed at corporate and hybrid events, conferences, classrooms, trade shows, and legal or government settings needing accessibility. Pricing is usage-based per minute with no subscriptions or setup fees.
