Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and noScribe when journalists generating diarized transcripts of recorded conversations matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

noScribe is a free, open-source desktop transcription tool that runs entirely on the user's own computer to protect the confidentiality of recordings. Licensed under GPL-3.0 and actively maintained, with a v0.7.2 maintenance release in June 2026, it is built around OpenAI's Whisper (via the faster-whisper library) for speech recognition and pyannote for speaker diarization, so it can distinguish between different speakers and label who said what. It understands around 60 languages and supports automatic or manually specified speaker counts. noScribe is primarily designed for producing high-quality transcripts of interviews for qualitative social research and journalistic work, and it ships with a dedicated companion editor, noScribeEdit, that synchronizes audio playback with the transcript text and provides search and replace, formatting, zoom, and playback-speed controls. It supports Windows (with optional CUDA acceleration on Nvidia GPUs), macOS on Apple Silicon, and Linux in both CPU and CUDA versions. Additional capabilities include batch transcription, pause detection and marking, an experimental overlapping-speech detection mode, and export to multiple formats such as HTML, VTT, and TXT, plus an available command-line interface for scripted use. Pricing varies by plan. Check the official website for current pricing.
