From an empty profile to a post that works.
Each tool does one job. Used in this order, they cover a short-form post from start to finish.
- 01
Set up the profile
Pick a handle people can spell and say out loud, then a bio that says what you do in one breath.
- 02
Write the post
Start with the first line, since it decides whether anyone stays. Then the caption, checked against each platform's limit before you paste it.
- 03
Make the images
Turn one wide image into a carousel that swipes as a single panorama, or into a grid that reads as one picture across your profile.
- 04
Check what worked
Compare engagement rates across posts, not views alone, to see which hooks and formats actually hold attention.
Questions
Good to know.
Are these tools really free?
Yes. Every tool runs in your browser, with no sign-up and no limit on how often you use it.
Do the image tools upload my pictures?
No. The carousel splitter and the grid maker cut your image on your own device, and the slices download straight from your browser. Nothing is sent to us.
Which platforms are they for?
Each tool says which platforms it's built for. Between them they cover TikTok, Instagram, YouTube Shorts, X, LinkedIn and Threads.
How are they different from Feedrick?
Each tool does one part of a post by hand. Feedrick does the whole thing: paste your website and it makes UGC videos with AI influencers, memes and carousels, then posts the ones you keep. It's free to start.
Want the posts, not just the parts?
Paste your website and Feedrick writes, films and posts UGC videos, memes and carousels for you. Free to start.
