Spintax (spin syntax)
Spintax is a writing format that hides several alternatives inside one text using curly braces and vertical bars — {like this|this way|that way}. When the text is used, one alternative is picked for each block, producing a different reading of the same message every time.
How the format works
A spin block is a pair of curly braces containing two or more options separated by a vertical bar. When the text is spun, one option per block is chosen and the braces disappear. Everything outside the braces stays exactly as you wrote it.
{Fresh batch|Just landed} — new stock in the store!
→ Fresh batch — new stock in the store!
→ Just landed — new stock in the store!Blocks combine. Two blocks with two options each produce 2 × 2 = 4 distinct posts; add a third block with three options and you have 12. You write once, and the combinations multiply on their own.
Why varied wording matters
Posting platforms and communities treat word-for-word identical content, posted to many places in a short window, as a signal of automation. Varying the wording between posts is one of the conservative practices that keeps bulk posting looking like what it should be: a person sharing something with several communities.
- Each group receives a caption that reads naturally on its own.
- No two groups see byte-identical text from the same run.
- You keep one message instead of maintaining twenty copies.
Spintax in GroupBlaster
GroupBlaster supports spintax natively in every campaign — free and Pro alike. Write your post with {option|option} blocks; when a run starts, each group gets its own variation resolved at fill time, before anything is typed into Facebook's composer.
- The composer always receives finished text — braces never reach Facebook.
- Wording stays stable within a run, so the posting history links back correctly.
- A new run draws fresh wording, so a daily campaign does not repeat yesterday's exact variant.
- An unbalanced pattern (a missing closing brace) is flagged in the editor and posts as plain text rather than failing.
Writing good spin blocks
Good spintax reads as if each variant were written on its own. A few habits keep the output natural:
- Swap phrases, not single words — “{Fresh drop|New arrivals} just landed” beats swapping one adjective.
- Vary sentence openings across blocks so variants differ from the first word.
- Keep every option grammatically complete — each one must stand alone in the sentence.
- Two or three strong options per block beat ten near-identical ones.
What spintax is not
Spintax is not artificial intelligence. It does not write new sentences, invent claims, or rephrase for tone — it chooses among alternatives you wrote. That is also why it is predictable: you have read every variant it can post, because you wrote them.
