4.5 out of 5
Scored by a Toolio reviewer after real useOur verdict
Readefine swaps words and phrases using its own dictionary engine, then layers on AI rewording that can simplify text for kids, translate it, change its tone, or convert units as you browse. The playful modes, like rewording as Yoda or a pirate, sit alongside more practical ones like ESL simplification. Custom AI prompts, though, are locked behind an upgraded subscription rather than included free.
✓What it does well

Flexible AI rewordingSimplifies, summarizes, translates or changes the tone of on-page text.

✕Where it falls short
Custom prompts cost extraEditing the AI's own prompts requires an upgraded, paid subscription.
In-app purchasesSells extra in-app purchases on top of the free extension.
Novelty modes add noisePlayful rewording styles like pirate or Yoda are more gimmick than practical without editing after.
