Frequently asked questions

What kind of content can TextExplainer explain?
Virtually anything: news articles, academic papers, legal documents, code snippets, math equations, scientific diagrams, charts, chemical structures, and more. The screenshot mode can even analyze images and UI elements.
Is my data private?
Your selected text and screenshots are sent to our AI backend only when you trigger an explanation. We do not store your content after generating the explanation. No data is collected in the background.
Why does the macOS version need Accessibility and Screen Recording permissions?
Accessibility access lets TextExplainer read the text you've selected in other apps. Screen Recording access enables the screenshot capture feature. Both are required by macOS for apps that interact with content from other applications.
Can I cancel my Pro subscription anytime?
Yes, you can cancel anytime from your Lemon Squeezy customer portal. Your Pro access continues until the end of your billing period. No questions asked.
Does the free plan really include all features?
Yes. The free plan includes all three modes (explain text, explain screenshot, ask anything) plus follow-up questions. The only limit is 30 explanations per month. Upgrade to Pro for unlimited use.
