You don't have to wordsmith captions yourself. Brandmundo has two layers of AI writing help: one-tap rewrites for quick fixes, and a conversational assistant for anything you can describe in a sentence. Both are free — text never costs credits.
One-tap rewrites
In edit mode on any idea, the Rewrite options give you targeted fixes without losing the post's intent:
- Improve — polish the phrasing, keep the length.
- Shorten / Expand — compress to about half, or flesh out with more detail.
- Rewrite — same idea, completely different angle.
- Hook, body or CTA only — surgical rewrites of just the opening line, the middle, or the call-to-action.
Hashtags have their own regenerate button that suggests a fresh, platform-appropriate set.
The assistant pane
When you compose a post on a desktop-sized screen, an assistant pane sits next to the editor. Talk to it like a colleague: “make this punchier”, “add a call to action for bookings”, “rewrite this for a LinkedIn audience”. It answers in the pane, and when it proposes a full caption you'll get an Apply caption button that drops the suggestion straight into your editor — nothing changes until you apply it.

It knows your brand
Every rewrite and assistant reply is grounded in your brand profile — tone, posting playbook, audience — so suggestions come back sounding like you, not like a generic AI. The more complete your profile, the better the writing.
