PageMod - Userscript|Extension|App Builder AI Agent

AI writes, previews & installs Greasemonkey/Tampermonkey userscripts and browser app.

PageMod is an Extension Builder AI Agent: describe a page change in plain words — it writes, previews & installs Greasemonkey/Tampermonkey userscripts and browser customizations. No developer required. Describe it once. It sticks. Tell the AI what you want in plain words: "hide the ads on this site," "auto-fill this form," "move this menu to the side." PageMod understands the page you're looking at, does the work, and saves it as a persistent page mod — the change stays even after you close and reopen the tab. Not a code generator. A wish executor. You never need to understand how it works. If you can say it in a sentence, PageMod can usually do it — it inspects the page, acts on it, and shows you the result live. The world's first VibeExtensioning agent Other AI tools write code for developers. PageMod is built for the browser and for everyone: describe a change, get a permanent improvement to any site — right in your own browser, and compatible with Tampermonkey scripts. Make the web yours • Clutter gone: popups, ads, banners in your way — gone with a sentence. • Drudgery gone: repeat sign-in forms and daily data-entry — filled in seconds. • Layout that suits you: shrink, move, restyle any element until the site feels right. • Your data, your way: turn a table or list into a clean CSV download. App mode — build mini apps, not just tweaks Beyond tweaking existing pages, PageMod can generate small standalone apps — a timer, a notepad, a converter — single-file HTML apps that run right in your browser, built in minutes from a one-line idea. It can also build a side panel app: your own Page Sidebar that opens any site in the side panel — ChatGPT, Todoist, YouTube — docked beside whatever you're browsing. Made for non-developers No setup, no syntax, no fear. If you can describe what you want, PageMod has you covered. Start from what others already built Not everything has to be made from scratch. The script market and the app market are full of ready-made mods — install one and use it as is, or tell the AI to change it: take a script someone else wrote and make it yours in one sentence. On any site, the floating button on the page shows a count of the featured scripts available there. Everyday examples • "Stop showing me these popups when I read articles." • "Remember my info and auto-fill this sign-in form." • "Make this dashboard show only the rows I care about." • "Give me a countdown timer for my workout." • "Turn this price list into a spreadsheet download." Try PageMod once. You'll wonder how you browsed without it.
