AE Spell Checker is an extension that checks spelling directly inside After Effects. It scans text layers across your composition, including all nested precomps, flags likely misspellings, and offers suggestions you can apply. A highlight-and-navigate feature helps you locate and fix flagged words in the comp.
The extension supports a custom dictionary and offers language options for English (US) and English (UK-strict). It runs on both PC and Mac, and is compatible with After Effects 2026, 2025, 2024 and 2023.
It ranks at 261 in the aescripts library. The 1.1.0 update expanded the Scan Active Comp button to cover nested precomps and added a Scan Selected Comps button for scanning comps selected in the Project panel. A demo video is available.
