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.

Spellar AI is a bot-free meeting note taker built by Spellar LTD for professionals who want their conversations captured without a bot joining the call. The app records directly on the user's Mac, iPhone, or iPad, so no participant appears in the meeting, and it produces transcripts in many languages with intelligent language detection. At the end of each meeting Spellar generates a structured summary that highlights key points and action items, and it offers customizable summary templates so the output can match different meeting types. A distinguishing feature is its model flexibility: users can switch between AI models such as different GPT, Gemini, Claude, and Perplexity options per meeting, per template, or per question, and a real-time copilot can assist during the conversation. Privacy is configurable: server-side transcription is opt-in rather than default, and users can run transcription on-device or bring their own AI key to keep calls private. Spellar syncs across macOS, iOS, and the web, and supports one-click export to tools like Notion, Jira, Linear, and Google Docs. It suits sales reps, consultants, and professionals who want discreet capture plus flexible, exportable meeting notes. Pricing varies by plan. Check the official website for current pricing.
