Limitations and notes

  • It only fixes spelling, accents, grammar and punctuation; it should not change meaning or style.
  • All the text is sent to the AI provider the site administrator configures.
  • TodoToolsOnline does not store or log the text; the provider handles it under its own policy: do not paste confidential data.
  • AI can make mistakes: always check the result.
  • There are per-minute and daily usage limits to prevent abuse.
  • If the administrator has not switched the provider on, the tool says so and processes nothing.
