How Hosiqo compares and tests toolsFinal recommendation
Shortlist EventCAT when providing multilingual live subtitles and audio at in-person conferences and seminars matters most, and Vibe when developers embedding local transcription via the cli or http api matters most. Run both through a week of actual calls to see which suits your workflow.

EventCAT is an AI-powered real-time interpretation and subtitling platform built by XL8 Inc. for meetings, webinars, and live conferences. It converts spoken audio into live captions and synthesized voice translation across more than 50 languages, allowing multilingual audiences to follow sessions without traditional interpreter booths. The platform offers two products: an OnlineMeeting mode that integrates with Zoom, Google Meet, and Microsoft Teams, and a Conference mode designed for in-person and hybrid events. For conferences, each session generates a unique QR code so attendees can view or listen to captions in their preferred language on a phone or tablet, while subtitles can also be projected on main event screens and pushed to YouTube and OBS streams. EventCAT exposes two processing modes, one tuned for low latency and one tuned for accuracy, and supports custom glossaries for industry and company-specific terminology. After an event it produces downloadable transcripts in multiple languages and AI-generated summaries. The service advertises SOC 2 certification and a stated policy of not storing or training on user data, and it is actively operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

Vibe is a free, open-source transcription application created by the developer thewh1teagle and distributed under the MIT license. It lets users transcribe audio and video files entirely offline on their own machine using OpenAI's Whisper models, so recordings of meetings, interviews, lectures, and calls never have to leave the device. Vibe runs on macOS, Windows, and Linux, with GPU acceleration available for NVIDIA, AMD, and Intel hardware, and it supports a very wide range of languages. It includes speaker diarization so different participants can be separated in the transcript, and it can export results in multiple formats including SRT, VTT, TXT, HTML, PDF, JSON, and DOCX. For automation and integration, Vibe also exposes a command-line interface and an HTTP API with Swagger documentation, making it usable inside larger pipelines. Built with the Tauri framework on top of whisper.cpp, it is actively maintained with frequent releases. Vibe is best suited to privacy-conscious individuals, developers, and teams who want a no-subscription, local-first way to turn recorded conversations into editable text. Pricing varies by plan. Check the official website for current pricing.
