Rephrase AI

Rephrase AI is a writing tool that helps you reword text by adjusting formality, complexity, brevity and creativity. You paste in a passage, sentence, paragraph or single word, then choose how you want it to change: make it more formal or casual, simpler or more advanced, longer or more concise, direct or expressive. The tool generates alternative versions while preserving your original meaning and voice.

You can select from writing profiles like Academic, Professional, Casual or Creative to shape how rephrases work. Sliders let you dial in specific adjustments: formality from casual to formal, complexity from simple to advanced, brevity from detailed to concise, and creativity from direct to expressive. SuperRephrase mode offers more substantial rewrites. The tool handles up to 3,000 characters per rephrase on the free plan and 10,000 on paid plans.

Rephrase AI also includes a free AI detector to scan text for common AI-writing signals and a summarizer for condensing longer passages. It runs in your browser with no installation needed.
