A social network without AI-written posts

Sincerus is built for exactly that. On Sincerus, the words in a post are typed by a person in an editor that blocks pasting, so a chatbot’s answer can’t be dropped in. Using AI to write posts breaks the Community Guidelines: such posts are removed, and repeated violations close the account. Checking your own spelling is fine. Post photos you took or made yourself. Images made with AI aren’t allowed; touching up your own photo with AI, like removing something in the background, is fine. A photo whose file says it was generated with AI is refused when it is uploaded, and others can be reported.

• When you write a post, a reply or your bio, paste, cut, drag and drop, Text from Camera and large text inserts are blocked. Apple’s Writing Tools and inline predictions don’t work there.
• Posting is confirmed with Face ID, Touch ID or the passcode and signed by the iPhone with App Attest, so scripts and server farms can’t post. See how verification works.
• The app looks at how a post was typed (speed, corrections, pauses), never at what it says. These signals are kept for 90 days and only help people review posts. A post that looks copied from somewhere is still published and quietly goes to review.
• The same text posted from several accounts is caught automatically.
• People review reports and flagged posts within 24 hours. Repeated violations close the account.

Someone could still retype a chatbot’s text by hand. It is slow, it breaks the rules, it leaves traces, and it can’t be done at the scale that fills other feeds.

Only to help you read, and only on your iPhone. Sincerus can translate a post, give you a short summary of a long thread (“In short”), suggest a tone label you can change, and screen incoming messages for spam. All of it runs on the device; Sincerus runs no AI on its servers, and AI never writes for you.

Not unless you opt in, and the setting is off by default. If you do opt in, only your public top-level posts can be included (never while your account is private; posts licensed while it was public can’t be recalled), without your name and with @mentions masked. Chats and profile information never are. Details are in the privacy policy.
