Where it falls short
  • Free-plan credits are a one-time 400 grant that never refills, pushing users to upgrade quickly (eesel AI pricing breakdown, 2026)
  • PowerPoint export loses fidelity, text boxes shift, fonts get substituted, long cards split unpredictably (ChatSlide review, 2026)
  • Trustpilot rating of 1.9/5 driven by unresponsive support on billing disputes and credit-deduction bugs
  • Even the top 'unlimited presentations' Premium tier still caps you at 12,000 characters input and 1,200 credits/year, not truly unlimited
  • PowerPoint support is limited; full functionality is Google Slides-only
  • Trustpilot TrustScore of just 2.2/5, with complaints about a strict 15-day cancellation window and no refunds after
