Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and TranscribeAudio when transcribing online lectures, courses, and webinars for study notes matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

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.

TranscribeAudio is a Chrome browser extension that captures the audio playing in any browser tab and turns it into real-time text, displayed in a repositionable floating caption overlay while you keep working. It is aimed at people who want live captions and transcripts for online meetings, lectures, courses, podcasts, webinars, and videos. Because it works from tab audio rather than joining calls as a meeting bot, it can transcribe Zoom, Google Meet, YouTube, Vimeo, and essentially any site with audio or video without sending notifications into the call. Transcription is powered by OpenAI's Whisper-based speech recognition, which the company says handles accents, background noise, and specialized terminology, and supports over 50 languages. Setup is a three-step flow: install from the Chrome Web Store, sign in, then click Start Transcribing on a tab. Finished transcripts can be exported as text files for notes, summaries, or sharing, with cloud storage listed as an upcoming feature. The product offers a free tier with paid upgrades for more usage, languages, and faster transcription.
