Frequently asked questions
Can AI writing tools make my writing detectable as AI?
Detectors are unreliable and any tool can produce text that looks machine-written. Follow your school or employer's rules on AI use, and be open about how you used it.
Is a grammar checker the same as an AI writer?
No. A grammar checker corrects and suggests edits to your text. An AI writer generates new text from a prompt. Some tools do both.
Which writing and grammar tools here need no credit card?
Based on the official pages we reviewed, Rytr is listed as not needing a credit card to start. Confirm at sign-up, because plans change.
