    Tips for better writing

    • Put the main idea early for readers scanning on mobile.
    • Keep intentional style choices separate from accidental errors.
    • Check mentions, hashtags, names, and claims before posting.
    • Keep the opening clear because readers may only see the first line.
    • Check names, handles, hashtags, links, and calls to action manually.
    • Use short sentences when the post needs to scan quickly on mobile.
    • Read the final post in its platform preview before publishing.

    Frequently asked questions

    Does the caption checker write captions for me?

    No. It checks and improves the text you provide; you remain in control of the caption and your voice.

    Can it keep a casual tone?

    Yes. Review the suggestions and choose a casual or creative tone when using the rewrite tools.

    Does it improve Instagram reach?

    No. It improves writing quality, not platform distribution or engagement.

    Can I keep my social-media voice?

    Yes. Review suggestions selectively and keep the words, punctuation, and style that are intentional for your audience.

    Does the checker optimize engagement?

    No. It helps with language quality and clarity; it does not predict reach, engagement, or platform performance.

    Can it check captions and longer posts?

    Yes. Paste the text you plan to publish and review the result before copying it back to your social platform.

    Does it verify links or claims?

    No. Check links, facts, mentions, permissions, and any claims separately before publishing.
