Hi Product Hunt community! 👋 I'm Rocco Caruso, the creator of **MultiProfile Autofill**. Like many of you, I deal with web forms every day—whether signing up for services, purchasing online, or handling administrative portals. Over time, I grew increasingly frustrated with two recurring problems: 1. **Context mixing:** Default browser autofill lumps personal, work, and freelance details together, often guessing wrong. Heavy password managers, on the other hand, require complex configurations just to manage different profiles. 2. **Anti-paste roadblocks:** Banking sites, checkout portals, and government platforms that disable `Ctrl+V` or block clipboard events, forcing you to re-type long IBANs, tax codes, or confirmation emails by hand. I built **MultiProfile Autofill** to solve these issues once and for all: fast, reliable, zero configuration, and 100% private. ### 🌟 What makes it different? - 👥 **Multiple Profiles:** Seamlessly switch between Personal, Work, or Custom profiles with one click or a keyboard shortcut. It even remembers your preferred profile for each specific website. - 🔓 **3-Tier Anti-Paste Bypass:** When a field blocks pasting or synthetic input, the engine automatically cascades through native setters, `execCommand`, and human-like keystroke simulation (12ms per key) to ensure values are entered successfully. - 🎯 **Smart 6-Language Heuristics:** Whole-word scoring across EN, IT, FR, DE, ES, and PT. It understands context, eliminating annoying false positives (e.g. no more pasting your last name into a first-name field, or mistaking a CAPTCHA for a ZIP code). - 🖼️ **Multi-Frame & Cross-Origin Support:** Works smoothly across nested payment and checkout iframes. - ↩️ **Full Form Undo:** Revert every filled field on the page with a single click if you ever change your mind. - 🔒 **100% Offline & Privacy-First:** No analytics, no tracking, and zero external network calls. Your data stays securely stored in your browser’s private storage, with optional JSON backups and optional encrypted Chrome Sync. - 📏 **Zero Data Truncation:** It respects field rules (`maxlength`, `pattern`) without ever silently cutting off phone numbers or sensitive values. If a field isn't compliant, it notifies you immediately. The extension is **100% free** (no ads, no paywalls) and built purely with lightweight Vanilla JS (Manifest V3). 👉 You can grab it directly on the [Chrome Web Store](https://chromewebstore.google.co...).
