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.

Meetingnotes is a free, open-source AI meeting notetaker for macOS created and maintained by developer Owen Gretzinger. It is designed for professionals who want private meeting notes without recurring subscription costs. The app captures both microphone and system audio directly on the user's Mac, so it works across any meeting platform without adding a bot to the call. It then provides a live transcript and generates AI-enhanced summaries that combine the transcript with any manual notes the user takes during the meeting. Transcription and summarization run through the user's own OpenAI API key, meaning users pay only for the API usage they consume rather than a flat subscription, and meeting data stays stored locally on the device. The source code is published on GitHub under the LGPL-3.0 license, so it can be inspected, modified, and contributed to. The project lists integrations such as Slack and Notion, with additional features in development. Meetingnotes is best for engineers and individuals who want a lightweight, transparent, bring-your-own-key meeting notetaker that keeps their data on their own machine. Pricing varies by plan. Check the official website for current pricing.
