Shortlist AudioPen when capturing and refining personal ideas, journal entries, or brainstorms by voice matters most, and Celeste AI when companies needing pay-as-you-go transcription without fixed subscriptions matters most. Try them side by side on real calls before deciding — needs vary by team.

Brazilian Portuguese-focused AI voice and transcription platform offering on-demand transcription plus a meeting assistant and AI notes, with credit-based and subscription plans.
AudioPen is a voice-to-text tool that captures spoken thoughts and turns them into polished written notes. You record your voice (or upload an audio file), and AudioPen transcribes the speech, then rewrites it into clear, structured text by fixing grammar, cutting filler words, and organizing rambling input into coherent prose. Rather than producing a verbatim transcript, it reshapes what you said into finished writing in a style you select or train over time, with preset and custom styles available. It supports multiple languages and can transcribe speech in one language while writing the output in another. A SuperSummaries feature combines several notes into a single cohesive summary, and existing notes can be reformatted for different purposes such as emails or to-do lists. Built by independent developer Louis Pereira, it runs across iOS, iPad, Apple Watch, Android, Mac, and a Chrome extension, with Zapier and webhook integrations for sending notes elsewhere. It is aimed at people who think out loud and want to convert informal speech into professional written content.

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.
