## About AISub

AISub helps users compare ChatGPT website prices and App Store subscriptions for ChatGPT, Claude, Gemini, Perplexity and Grok. Explore regional prices, currency conversions, tax labels and recorded price changes, then plan an AI subscription budget using linked price quotes. Public comparisons are free, with optional Pro features for expanded alerts and budget assistance.

## About Petal

Petal is a personal PDF editor that works in the browser. Instead of using menus and toolbars, you describe the change you want in plain words and Petal applies it to your document.

According to the site, it can edit, merge, split and convert PDFs. It describes itself as private, safe and only yours, and it can be started for free.

Petal is aimed at individuals who need to change PDF files without learning a full PDF editing tool. Paid plans exist alongside the free start, though the page text does not detail what each plan includes.
