An honest editorial snapshot from this tool's profile — not a paid placement.
Echoly renders translated subtitles and near-realtime AI voice dubbing directly inside the video player — no tab switching, no popups. It supports 48 language pairs and works on YouTube, Coursera, and Udemy, with subtitles arriving around 680 ms after the speaker. Plans range from a genuinely free tier (500 credits/month, no card required) to a Max tier with sub-second realtime voice dubbing.

Pros
- Genuinely usable free tier: 500 credits/month, no credit card, no time limit
- Very low setup friction — works inside the existing player with no tab switching
- Both subtitles and voice dubbing available on every plan including Free
- Clear, honest public pricing with no hidden fees or upsell popups
Cons
- Chrome-only — no Firefox, Safari, Edge, or mobile app support
- Limited to 3 platforms (YouTube, Coursera, Udemy); most video sites are unsupported
- Voice dubbing runs a couple of seconds behind on Free and Pro — only Max gets sub-second latency, at $16.60/mo
- 500 free credits/month will run out quickly for heavy users; no clarity on how many credits a typical hour of video costs
- Very new product (v1.0.0) with a short track record — reliability, platform longevity, and API stability are unproven
- No voice cloning or speaker matching — AI voice does not mimic the original speaker's tone or identity
