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.

Riverside is a web-based recording and editing studio built primarily for podcasters and video creators, with capabilities that extend to remote interviews and meetings. Participants join through a browser link without signing up, and Riverside records each person's audio and video locally on their own device before uploading the high-quality files after the session, which avoids the compression and dropout problems of standard video-call recording. Once a session is recorded or an existing file is uploaded, Riverside automatically generates a transcript using AI speech recognition, detects and labels separate speakers, and supports transcription across more than 100 languages. The transcript can be downloaded as plain text or as SRT/VTT caption files, and it powers text-based editing, where users trim or rearrange the recording by editing the transcript rather than a waveform. Riverside also offers AI clip generation for short-form social video and a teleprompter. It is aimed at podcasters, content creators, marketing teams, and anyone running recorded interviews or small group conversations that need clean transcripts and captions. Pricing varies by plan. Check the official website for current pricing.
