Frequently Asked Questions
Should the same post go to every platform?
No, and cross-posting identical copy is immediately obvious. LinkedIn rewards a considered opening line and paragraph breaks, X rewards compression, Instagram rewards a hook before the truncation point. Same idea, different execution.
How do I make AI copy not sound like AI?
Cut the opening throat-clearing and the closing call to action, both of which language models over-produce. Add one specific detail only you would know. That single concrete detail does more than any amount of rewriting.
How long should a post be?
X caps at 280 characters. LinkedIn truncates at around 200 characters before "see more", so the hook must land first. Instagram truncates at about 125. In every case the opening line does the work.
Is my input private?
AI tools must send text to a language model to get a response, unlike the rest of Farvixo which runs locally. Do not paste anything confidential.
Can it write a thread or carousel?
Ask for it explicitly — say how many parts and what each should cover. A thread written as one block and split afterwards reads badly; written as a thread, it does not.

Tips for better results

- Keep important text away from the edges; platforms crop previews differently in feed and full view.
- Platform dimensions change. Re-check anything you produced more than a few months ago.
Common problems and how to fix them
The image was cropped after upload
The aspect ratio does not match what that placement uses. Pick the preset for the exact placement, not the generic platform size.
The caption was truncated
The preview limit is shorter than the posting limit. Put the essential line first.
Colours look different once posted
Platforms re-compress uploads. Avoid heavy gradients and very fine detail, which suffer most.
