Is Sincerus a good alternative to X?

If you want to read and write short posts knowing a person typed each one, Sincerus is built for that: no bots, no AI-written posts, clearly marked ads that Premium removes, and Premium never ranks anyone higher. If you need video, Android or the audience you already have on X (Twitter), Sincerus isn’t there yet.

How does Sincerus compare with X, Bluesky, Threads and Mastodon?

What doesn’t Sincerus have?

  • Video. A post is text, up to 280 characters (1,000 with Premium), with one link or up to 2 photos.
  • Android and a web app.
  • Editing a post after it is published. Premium adds Undo post, a short delay before a post goes out.

Is Sincerus available in Türkiye?

Sincerus is made for the United States and Türkiye, in English and Turkish. It is for people 18 and older; in Türkiye they also confirm their age with an e-Devlet age token; sign-ups there open once that check is ready (age verification). There is also a Turkish version of this page.
