Read the internet on your terms. ReframeAI is a Safari extension and iOS app that rewrites web content to match your tone, style, and perspective — privately, on your device. Reframe Any Page in Safari Tap the ReframeAI extension while browsing and hit "Reframe Page" to rewrite the entire article, news story, or post through your preferred lens. Political lean, tone, factual precision — all configurable. Reframe Selected Text Anywhere Select any text in any app, tap Share → ReframeAI, and get a rewritten version instantly. Uses Apple's on-device AI — no internet connection or API key required. 13 Tone Dimensions Dial in exactly how you want content to sound: Factual · Scientific · Authoritative · Assertive · Inspirational · Optimistic · Empathetic · Casual · Humorous · Sarcastic · Dramatic · Cynical · Provocative Each tone has Off, Mid, and Max intensity so you stay in precise control. Political Perspective Slider Shift content from Very Liberal to Very Conservative — or keep it neutral. ReframeAI applies the framing naturally, the way a writer with that viewpoint would, never heavy-handedly. Keep Facts & Ensure Truthiness Enable this to lock down all facts, statistics, names, and verifiable claims. The tone changes; the truth doesn't. Custom Instructions Add your own standing instructions — "Use formal academic language," "Avoid corporate jargon," "Write for a general audience" — applied globally or per website. Domain-Level Preferences Set different tone profiles for different sites. Prefer dry factual language on news sites but something warmer on personal blogs? Done. Reframe History Every reframe is saved so you can revisit, compare, and jump back to the original page. Private by Design The Share Extension uses Apple's on-device language model. No text leaves your device. No accounts. No subscriptions.
