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.

Simon Says is an AI transcription, captioning, and translation platform built for professional audio and video production workflows. Users upload audio or video and Simon Says transcribes the speech into text, with speaker identification to separate dialogue, and can generate subtitles and captions using built-in visual editing tools. The platform supports transcription and translation across roughly a hundred languages, making it useful for international distribution and localization. A defining characteristic is its focus on production environments: Simon Says integrates with industry-standard editing software such as Final Cut Pro, Adobe Premiere Pro, DaVinci Resolve, and Avid, so transcripts and captions can move directly into editing timelines. This positions it as a transcription and captioning layer for video editors, producers, post-production teams, and content creators rather than a meeting note-taker. It is aimed at professionals who need accurate, editable transcripts and subtitles that fit into established editing pipelines, as well as researchers and creators who need reliable speech-to-text and multilingual captioning. Pricing varies by plan. Check the official website for current pricing.
