TikTok Caption Checker validates video captions against TikTok's 2,200-character limit (expanded from 150 in 2022) and analyzes caption effectiveness for the platform's discovery algorithm. It checks hashtag usage, counts @mentions, identifies trending sounds or challenges referenced in the caption, and scores the caption for searchability since TikTok's search increasingly acts as a search engine for Gen Z users. The tool previews how the caption appears in-feed with the fold point indicated.
TikTok content creators optimizing for discovery, social media managers scheduling TikTok content, and digital marketers running TikTok campaigns. The tool runs entirely in your browser — your data never leaves your device.
