Frequently asked questions

How accurate are the results?

LingualShift uses Anthropic's Claude AI for Translate, Context Shift, and Summarize. Results are generally excellent but AI-generated content may occasionally contain errors. Do not rely on it for legal, medical, or safety-critical purposes.

What is Context Shift?

Context Shift rewrites your text for a specific situation instead of just slang ↔ formal — pick from 10 presets including Professional Email, Legal Document, ELI5, Academic, Marketing Copy, Diplomatic & Tactful, Direct & Concise, Customer Support, Explain to a Patient, and Job Interview.

What is Summarize, and how does PDF upload work?

Summarize gives you the gist and key points of any text. Paste text directly, or (Pro) upload a PDF and LingualShift will extract and summarize its content. Uploaded PDF files are not stored — only the resulting summary is saved to your history.

How does Custom Glossary work? PRO

Add terms you want translated a specific way — names, brand terms, industry jargon — and LingualShift will apply them consistently across your results. Manage your glossary from Settings → Custom Glossary.

How do I add the Home Screen widget?

How do I cancel my subscription?

How do I delete my account?

What's my daily limit on the free plan?

What languages are supported?
