How Hosiqo compares and tests toolsFinal recommendation
Shortlist Felo Subtitles when following and translating multilingual video meetings on zoom, google meet, teams, or webex in real time matters most, and Kai for Chrome when generating quick meeting summaries and action items without any setup matters most. Test each on your own meetings; the right choice tends to become obvious quickly.

Felo Subtitles, made by Felo Inc. (Sparticle), is a real-time transcription and translation tool delivered as a Chrome/Edge browser extension plus companion desktop apps for Windows and macOS. It listens to meeting and video audio, recognizes speech, and overlays live captions with instant translation into other languages, so participants can follow conversations across language barriers. The browser extension captions web-based audio such as Google Meet (web), YouTube Live, Twitch, and Facebook Live, while the separate Felo desktop app extends coverage to Zoom, Microsoft Teams, Webex, and Tencent Meeting without a bot joining the call. It recognizes speech in roughly 23 languages and translates into about 20 target languages. Captured sessions can be saved as transcripts and exported as text, and the tool offers AI summaries using templates for contexts like sales, learning, and one-on-ones. Custom speech and translation dictionaries let teams add industry terminology. It is aimed at IT, research, HR, legal, education, and video-creator users needing multilingual meeting communication.

Kai is a Chrome extension that transcribes and summarizes meetings entirely within the browser, running the full pipeline on the user's own device. Built by Morgen, the team behind the Morgen calendar app, it captures audio from any meeting or audio tab in Chrome, including Google Meet, the Zoom web client, and Microsoft Teams, without sending a bot into the call and without requiring an account or sign-up. Recording is triggered with a keyboard shortcut from the meeting tab. Audio capture happens in an offscreen document inside the extension and is transcribed locally using a Whisper speech-to-text model running via WebGPU or WebAssembly, so the audio never leaves the machine. At the end of a call, a local language model produces a clean summary with decisions, topics, and action items, including who is responsible. A side-panel interface lets users follow the transcript live during the meeting, and notes can optionally be emailed to a team in one click, at which point only the final text is shared. This makes Kai well suited to individuals who want fast, private, browser-based meeting notes without installing a desktop app or adding a visible bot, with an initial focus on English-language meetings. Pricing varies by plan. Check the official website for current pricing.
