Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and HoverNotes when capturing code and diagrams from technical youtube lectures matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

HoverNotes is an AI-powered note-taking tool delivered as a Chrome extension, designed for students and learners who study from recorded lectures and online course videos. Rather than relying on audio transcription alone, HoverNotes analyzes video frames as you watch, so it can capture on-screen context such as code snippets, mathematical equations, and diagrams alongside spoken content. The extension generates AI notes while you watch and saves them as plain Markdown files directly to your local file system, which makes them easy to use with tools like Obsidian or other Markdown-based knowledge bases. Users can also capture single-click screenshots embedded with clickable timestamps that jump back to the exact moment in the video. HoverNotes works across common video learning platforms including YouTube, Coursera, Udemy, LinkedIn Learning, Bilibili, and university lecture portals. It runs on a freemium model with a limited monthly allotment of AI note generation on the free plan and paid tiers for heavier use. The tool is best suited to self-directed learners studying from video, and its local-Markdown approach appeals to people who want full ownership of their notes. Pricing varies by plan. Check the official website for current pricing.
