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.

Whisper Memos is an AI voice-recording app for iPhone and Apple Watch, created by independent developer Vojtech Rinik, that records spoken memos and delivers them back as nicely formatted email transcripts within seconds. You can start a recording from a one-tap iPhone lock-screen widget or hands-free from an Apple Watch complication, making it suited to quick capture of rambling thoughts, meeting notes, lectures, or journal entries. Under the hood it offers multiple transcription engines, including OpenAI Whisper, ElevenLabs, and Cohere, and supports many languages with automatic paragraphing. Every voice note can get an automatic AI summary, and you can create custom summary tabs with your own prompts, for example to extract action items from meeting notes or to reorganize thoughts by topic. The app supports importing audio files in formats such as MP3, M4A, WAV, AAC, and FLAC. An Agents system routes different memos to different destinations, and integrations cover Notion, Trello, Things 3, Todoist, Day One, Evernote, Reflect, and Drafts, plus thousands more via Zapier or Mail Drop. It markets itself explicitly as a dictaphone, an audio recorder for meetings, and a voice journaling app, and has been covered by outlets like Six Colors and MacSparky. Pricing varies by plan.
