Reddit post checker

Compare a Reddit draft with rules you paste. Review links, promotional language and questions before you post, with no automatic posting.

Text checks run in this browser. Nothing is posted or uploaded.

Review links, promotional phrases and the context of your contribution before you submit it to a community.

What this tool does

Runs transparent text checks on your draft and highlights rule text you provide. It does not predict moderation decisions, shadowbans or upvotes. Read the current rules and review the draft yourself.

Method reviewed 2026-10-17. Version 1.0 · First public release.

Before you use the result

Does a clean result guarantee the post stays up?

No. Moderators consider context, account history and community expectations that this text check cannot judge.

Does the checker publish anything?

No. Drafts and pasted rules stay in your browser.
