Social posts from an article

Do4U writes posts for LinkedIn, Facebook and Instagram from an article or a web address, in the language of the article or in a language you choose. The AI writes the text and suggests hashtags; the code counts the length for each channel in characters as people see them, tidies the hashtags (no spaces, no duplicates, a limit per channel) and leaves out every link, e-mail address and @mention that is not in your source. You can ask for up to three variants per channel and copy each post with one click.

Questions and answers

Does Do4U invent facts, quotes or links for my posts?

It is told to use only what is in your article. On top of that, the code takes out every web address, e-mail address and @mention that is not in your source and lists it, and it marks numbers that are not in your article. Please still read each post before you publish it.

Why does Instagram get no link in the post?

Instagram does not make links in captions clickable. Do4U therefore leaves them out and reminds you to put the link in your profile (link in bio).

What happens when a post is too long?

The code counts every post in characters as people see them and compares it with the limit of the channel. A post that is too long is marked, not cut, so you decide what to shorten. The limits are settings and can change when a platform changes its rules.

Is my text stored?

Only as long as needed: 7 days on Free, 30 days with a package – or not at all if you choose not to store it. Processing happens on our own servers in the EU (Poland).

Can I use the result right away?
