Spintax generator & tester
Preview every variation and count the combinations — or paste plain text and let auto-spin write the spintax for you.
Open the tool →Duplicate post checker
See how similar your post variations really are, and get the exact shared phrases to rewrite.
Open the tool →Then actually post it
These tools prepare the content. Group Posting delivers it — one variation per group, on a schedule. Free forever plan.
Add to ChromeThey are built to be used in order
These are not a grab-bag of unrelated widgets. They follow the sequence a real group-posting workflow actually takes, and each one hands its output to the next.
Write the variations
Use the spintax generator to turn one post into many, or paste plain text and let auto-spin do the marking up. You get an exact combination count and a preview of the actual outputs.
Check they are actually different
Send them straight into the duplicate post checker with one click. This is the step people skip, and it is the one that reveals whether "5,000 combinations" means anything — usually it means less than you would hope.
Fix what the checker flagged
The checker lists the exact phrases your closest pair shares, so the rewrite is a to-do list rather than a guess. Change the opening line and the length first — those move the number furthest.
Post one variation per group
Variations only help if each group gets a different one, which is where a browser extension takes over from a web page. Group Posting rotates them across your groups and paces the run so it does not arrive as one burst.
Why these are free, and what the catch is
There is no catch worth the word, but there is an honest answer. These tools cost us essentially nothing to run — they are JavaScript that executes on your machine, so there is no server bill that scales with usage, no account to create and no rate limit to enforce. We can leave them open indefinitely because they are genuinely cheap.
What we get is the chance to show you something true. The duplicate checker will tell you your variations are too similar, and it will be right, and the honest fix is to write genuinely different posts — which is slow by hand and is the job our product does. We would rather demonstrate that than assert it in an ad.
Nothing you type is uploaded. No sign-up, no email wall, no watermark, no export limit. If you use these forever and never install anything, that is a completely reasonable outcome and the tools will keep working.
More tools are coming. Post preview with the "See more" cutoff, a posting-schedule planner and a group-value scorecard are next. If there is something fiddly you keep doing by hand, tell us at [email protected] — the list is driven by what people ask for.
