Frequently Asked Questions
Does this rewrite my content?
No — it only trims text that exceeds a platform's character limit. The original content is never altered unless it's too long, in which case it's cut at a word boundary and an ellipsis is added.
What are the character limits used?
Twitter: 280, LinkedIn: 3,000, Instagram: 2,200, TikTok: 2,200, Facebook: 63,206, YouTube: 5,000.
Can I write platform-specific versions manually?
Not yet — each card is derived from the same source. For deep per-platform customisation, copy each card individually and edit in your social media composer.
