ExploreQuestions
What these are, and what they are not.
Yes, with no account, no email, and no usage limit. They run entirely in your browser, which is also why there is nothing to sign up for: no request ever reaches our servers.
No. Every calculation happens locally in your browser. Text you paste into the word counter, readability checker, or density tool is never uploaded, stored, or logged.
Because the people who need a schema generator or a RevPAR calculator are usually the same people who eventually need content written for them. We would rather be useful first. There is no gate and no catch on any of these.
No, and that is deliberate. Every tool here is deterministic: the same input always produces the same output, instantly, with no model in the loop. The AI side of inkSTR lives in the product, behind an account.
Yes. If there is a calculation or generator you keep doing by hand, email hello@inkstr.co and tell us what it is.
The tools are free. The hard part is doing it every week.
InkSTR researches the keywords, writes the articles, and publishes them to your site on a schedule, with the on-page work already done.
