Frequently Asked Questions
How do I get a caption that sounds like me?
Describe the photo and say who you are talking to and in what tone. "Casual caption for a beach photo, aimed at friends, slightly self-deprecating" produces something usable; "beach caption" produces the generic line everyone has seen.
How long should an Instagram caption be?
Instagram truncates at around 125 characters, so the hook must land before that. Longer captions work well when the first line earns the tap — a question or an unexpected statement rather than a summary.
Should I post AI captions unedited?
No. AI output tends toward the generic and over-enthusiastic, and it reads as such to an audience that sees a lot of it. Use it as a starting point and put your own detail in — that is what makes a caption feel human.
Is my text private?
AI tools have to send your text to a language model, unlike the rest of Farvixo which processes locally. Do not paste anything confidential into any AI tool.
Where should hashtags go?
Either at the end of the caption or in the first comment. Instagram treats both the same for reach, so it comes down to whether you want them visible in the caption.

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.
