Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and Mr. Transcription when transcribing interviews and lectures with speaker separation matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Japanese AI transcription service (文字起こしさん) that converts audio, video, images, and PDFs to text and can auto-summarize recordings into meeting minutes.
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.

Mr. Transcription (文字起こしさん) is a Japanese AI transcription service that converts audio, video, image, and PDF files into text directly in the browser.

The service operates a free tier offering a limited amount of daily audio and image transcription after registration, alongside several paid monthly and annual plans that scale up monthly transcription hours. It is currently operating and is used for meeting minutes, interviews, lecture notes, and subtitle creation, with broad multilingual coverage centered on Japanese. Pricing varies by plan.
