Metadata AI in Nakxi — Generate per field, with the store limit on every input.

Store limits

Written to the fields that exist

Not a blank chat box. Every draft is sized to the field it goes into.

  • 30 Title / app name App Store and Google Play
  • 30 Subtitle App Store, next to the icon
  • 80 Short description Google Play
  • 170 Promotional text App Store, editable anytime
  • 4,000 Description Both stores

How it works

Copy you'd actually ship

  1. Start from your project

    App details and competitor terms sit next to the fields, so drafts fit your category.

  2. Generate field by field

    Title, subtitle, promo, and description each have their own Generate button.

  3. Edit for honesty

    Cut claims the product can't back up. Keep keywords that are real gaps.

  4. Check length, then localize

    Counters keep you inside store limits. Clone into other languages when ready.

Screenshot captions

A second pass for the headlines on each slide

Captions, not the description shrunk

Screenshot Copy AI writes per-slide headlines using frame order, text roles, and the copy already on the slide.

  • Set audience, goal, tone, and length
  • Improve existing captions or write new ones
  • Edit inline in Screenshot Studio

Questions people ask

Listing copy vs screenshot captions — and what AI won't do.

What is Metadata AI?

Metadata AI is Nakxi's App Store description generator. It drafts titles, subtitles, promotional text, and descriptions for App Store and Google Play listings — inside the character limits those stores enforce. You edit every field before anything is published.

What are the App Store and Google Play character limits?

App name: 30 characters on both stores. App Store subtitle: 30. Google Play short description: 80. App Store promotional text: 170. Full description: 4,000 on both stores. Nakxi shows a live counter on every field.

Is screenshot copy the same as listing metadata?

No. Metadata is the indexed listing text (title, subtitle, descriptions). Screenshot Copy AI is a separate pass for the headline and caption on each slide, using frame order and text roles so captions fit the visual.

Does it work for Google Play listings?

Yes. The same project holds App Store and Google Play fields, including the Play short description. Generate each one separately, since the limits and the way each store uses the text differ.

Does AI copy guarantee more downloads?

No. Better copy can make a listing clearer; it cannot guarantee rankings or installs. Treat drafts as a starting point, check claims against the product, and use the free character counter for a length check before you paste into the consoles.

Is Metadata AI included on the free plan?

The free plan includes 10 one-time AI credits so you can try generation. Creator unlocks Metadata AI and Screenshot Copy AI as ongoing tools, with 300 credits a month. Character counters work on every plan.

Can I translate the copy into other languages?

Yes. Once the source listing is right, App Store Localization clones it into 80+ languages, including RTL, with the same field limits applied.
