Fluently

Fluently is a browser extension that generates AI‑based subtitles for any YouTube video and translates them into more than twenty languages. Users click a “Translate” button, select the desired output language, and the service streams the translated captions while the video plays, allowing immediate viewing without waiting for a full download.

The tool also includes an interactive Q&A feature: clicking “Ask” on any caption opens a prompt where the AI can explain or clarify the specific segment. This is intended for viewers who need additional context or language assistance while watching.

A free tier offers a limited number of translations per month, and paid plans provide additional hourly allowances and priority support. The extension is installed via Chrome, requires no credit card to start, and aims to improve on YouTube’s built‑in auto‑translate by delivering more accurate, AI‑generated captions.
