Free use

Without a pass you can compare one reference with one translation (SRT or WebVTT, opened or pasted), adjust tolerances and reading speed, see every finding on screen, and copy or download the findings as text.

Optional 30-Day Pass

A one-time payment of $9 USD with Square or PayPal unlocks, for 30 days from payment in the same browser: comparing up to five translations against one reference at once, saved tolerance and reading-speed presets, and PDF and CSV client reports grouped by track. The pass does not renew and there is no account. If you clear this site’s cookies, that browser loses access to the pass.

What the check is

CaptionDelta compares the timecodes of subtitle files that were cut for the same picture and counts reading speed from the visible text. Findings depend on the tolerances you choose and are aids for your own review. CaptionDelta does not judge translation accuracy, meaning or spelling, does not listen to audio or watch video, and does not guarantee that a file meets a client’s or platform’s delivery specification.
