How Hosiqo compares and tests toolsFinal recommendation
Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and oTranscribe when academic and qualitative researchers transcribing fieldwork or oral-history recordings matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

oTranscribe is a free, open-source (MIT license) web app, created by Elliot Bentley and maintained by the MuckRock Foundation, that takes the pain out of transcribing recorded interviews. It runs in the browser on desktop computers and places an integrated audio or video player alongside a text editor, so you can pause, rewind, and fast-forward your recording using keyboard shortcuts without taking your hands off the keys or switching between apps. It is built for journalists, researchers, oral historians, and students who type up interviews and recordings themselves. Rather than using automatic speech recognition, oTranscribe assists manual transcription: you listen and type, inserting interactive timestamps (Ctrl+J) that you can click to jump back to that moment in the media. Your transcript autosaves to the browser's local storage, and audio files never leave your computer, keeping work private. Finished transcripts can be exported to Markdown, plain text, or oTranscribe's own .otr format, or sent to Google Drive. Rich-text formatting and adjustable playback speed are supported.
