How Hosiqo compares and tests toolsFinal recommendation
Shortlist Celeste AI when brazilian teams transcribing meetings and calls in portuguese matters most, and MacParakeet when system-wide dictation across applications for privacy-conscious users matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

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.

MacParakeet is a free, open-source voice application for Apple Silicon Macs that runs speech recognition entirely on-device using NVIDIA's Parakeet TDT model via FluidAudio CoreML. Beyond system-wide dictation and file or URL transcription, it includes a meeting recording mode with live transcript preview, in-app note-taking, and export, plus meeting calendar integration through macOS EventKit that can show reminders and optionally auto-start recording. Because all speech recognition runs locally, the project states that audio remains on the device, with no cloud speech-to-text, no required accounts, and opt-out telemetry. It supports around 25 European languages with automatic detection and includes a text cleanup pipeline for filler removal, custom word replacements, and snippet expansion. Optional AI features such as summaries, chat, and text formatting can be enabled through cloud or local providers when the user chooses. Built with Swift and SwiftUI and distributed under the GPL-3.0 license, MacParakeet is actively maintained on GitHub and can be installed via a notarized DMG, a Homebrew cask, or built from source. It is positioned as a privacy-respecting, bot-free option for capturing meetings directly from the Mac. Pricing varies by plan. Check the official website for current pricing.
