# Changelog

> Product and API changes.

## 2026-05-22

* Raised API-key and free-plan generation rate limits while keeping credit
  charges as the primary abuse/cost control.
* Added PMC/NCBI BioC extraction for open-access scientific articles.
* Added bot-check/CAPTCHA extraction guards so blocked source pages fail and
  refund instead of becoming infographic content.
* Added selectable meme aspect ratios and PDF/PPTX/image primary source
  uploads for meme generation.

  Instagram image posts/carousels, Instagram and TikTok covers, and verified
  TikTok photo/slideshow image arrays.

## 2026-05-21

* Added the Meme generator tab on `/app/generate`.
