Questions people ask
- Are these tools free?
- Yes, with no sign-up and no email to give. The tools that read Reddit or ask an AI have a daily limit per person, so they stay free for everyone.
- Do you keep what I type?
- The tools that work in your browser (formatting, banner size, search, ads cost, username ideas) never send what you type to us; only a name you ask us to check is sent. The tools that read Reddit or ask an AI keep the answer for a while, so the next person who asks the same thing gets it at once and you can share a link to it. Anyone with that link can see what was asked. To count the daily limit we keep a code made from your address with a secret key, a new one each day, and delete it after two days. Answers are deleted a month after they stop being shared.
- Where does the data come from?
- Most come from Reddit itself: the public pages anyone can open, read when you ask, or shared from someone who asked the same thing a little earlier. Three tools also use AI: the rules checker and the post template judge your post or write an outline from the subreddit's rules, and the subreddit finder ranks what Reddit's search returns. The ChatGPT citation checker asks ChatGPT itself. Each tool says what it read and when, and facts about Reddit's rules come from Reddit's own help pages, with the date we read them.
- Why does a tool sometimes say to try again later?
- Each tool has a daily ceiling, and the ones that read Reddit only do so when Reddit isn't busy for us. When either is reached, the tool says so instead of guessing.
