Hush

Select any page element, style it, hide sensitive info, and export as image.

Hush is a redaction and annotation tool that lives in your browser. Pick any element on any page — a tweet, a card, an invoice row, a dashboard widget — and hide the sensitive bits before you screenshot, share, or paste. Export as a sharp PNG or as a true-vector SVG that opens cleanly in Figma. Built for people who screenshot for a living and have leaked something at least once — support agents masking customer data in tickets, sales reps redacting CRMs for demo decks, designers capturing UI for bug reports, founders blurring revenue lines on a tweet. Anyone who has ever almost shipped a screenshot with the wrong email visible. ━━━━━━━━━━━━━━━━━━━━ WHAT YOU GET ━━━━━━━━━━━━━━━━━━━━ ELEMENT-AWARE SELECTION Hover any DOM element — Hush highlights its exact bounds. Click to lock it in. Press Tab to walk up to the parent. Works on tables, posts, sidebars, modals, anything the page renders. No more dragging a perfect crop box around content that keeps moving. FOUR REDACTION STYLES Hide an element entirely. Blur it (0–40 px slider). Pixelate it (the kind that reads as "censored on purpose"). Or Solid Redact — paint over with the element's text color so it looks like a real black bar. One-click clear button on each slider. SMART REDACT One button that scans the selected area for emails, phone numbers, credit cards (Luhn-validated), SSNs, IBANs, IP addresses, JWTs, API keys, and tokenised URLs — and black-bars each match individually. Catches things you would miss visually. All inside the browser, no data sent anywhere. SMART REPLACE Same engine, different action: swap real values with realistic samples (john.doe@example.com, 4242 4242 4242 4242, +1-555-0100). The screenshot stays readable and demo-ready, but completely safe to share. INDUSTRY PRESETS Payments demo · Healthcare-safe · GDPR demo · Auth & secrets. One click flips the right pattern boxes for your vertical. Stop manually toggling checkboxes every screenshot. MULTI-SELECT WITH SHIFT Hold Shift and click multiple elements to apply the same redaction to all of them at once. Or paste a CSS selector (.email, [data-balance]) into the Match input and Hush adds every match to your selection. STICKY ANNOTATION TOOLS Arrows, numbered markers (1, 2, 3…), highlight boxes, text labels. Pick a tool once, drop as many as you need. After creation, drag any annotation to move it. Drag corner handles to resize. Press Delete to remove. Style each one with custom stroke colour, fill, width, corner radius, font, and size. CROP BOUNDS Eight drag handles around your primary selection let you extend the export region beyond the element's natural bounds — perfect when you want a few pixels of breathing room. WATERMARKS — TEXT AND IMAGE Stamp every export with custom text ("Internal Only", "Confidential"), an uploaded image or SVG (your company logo), or both. Five corner positions. TEMPLATES PER SITE Save your redaction setup as a named template per origin. Reload the page, click Apply — every selector reapplies with the same redaction style. Built for repeat dashboard demos and recurring support flows. EXPORT IN PNG, SVG, OR SVG·DOM PNG for raster (Slack, Linear, Notion, email — anywhere). True-vector SVG with editable text, shapes, and image fills (drag the file into Figma and it opens as real layers). SVG·DOM for pixel-faithful browser-only output. All three are also one-click Copy to clipboard. FLOATING LAUNCHER A small movable pill at the bottom-right of every page. Click to start, drag to reposition, position remembers itself. No more hunting for the toolbar icon. KEYBOARD SHORTCUTS H hide · S solid · B blur · P pixelate · R reset · C copy · Cmd+Z undo (any operation) · Tab walk to parent · Esc cancel · Shift+click add to selection · Delete remove annotation. RIGHT-CLICK MENU "Redact this with Hush" on every element on every page. Skip the toolbar. UNIFIED UNDO Cmd+Z reverses any operation in order — style change, smart redact, replace, annotation drop, drag, resize, crop, template apply. One stack. No mode switches. PAGES STAY INERT While the panel is open, clicks on links and buttons on the underlying page do nothing — no accidental navigation, no form submits, no input focus stealing your keyboard. ━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━ — Support agents capturing tickets without leaking customer details — Sales and CS demoing dashboards with real-looking but fake data — Designers grabbing UI for bug reports and Figma references — Product managers writing internal updates with screenshots — Developers redacting console output, API keys, and dotfiles before pasting in chat — Founders and marketers tweeting metrics without showing the actual number — Anyone who has ever pulled a screenshot back from Slack going "wait, no" ━━━━━━━━━━━━━━━━━━━━ HOW IT WORKS ━━━━━━━━━━━━━━━━━━━━ Hush installs a small floating launcher at the bottom-right of every page. Click it to bring up the toolbar. Pick an element. Apply one of the redaction styles, run Smart Redact, drop annotations, then Copy or Download. The whole thing runs inside your browser. There is no Hush server. The only network call the extension can make is when you click the brand badge to open fourline.ai in a new tab. Permissions explained: activeTab + scripting — lets Hush read and modify the page you are actually working on, and inject the rendering library when you click Export. Activated only when you click the icon, the launcher, the right-click menu, or open the panel. downloads — saves the PNG / SVG files you export to your local Downloads folder. storage — remembers your launcher position, last-used redaction style per site, and saved templates. Stored locally in your browser, never transmitted. contextMenus — adds the "Redact this with Hush" right-click entry on web pages. Content script on all sites — required so the floating launcher and shortcut handlers can appear wherever you want to redact. Hush does not log, transmit, or analyse anything from those sites. ━━━━━━━━━━━━━━━━━━━━ WHAT'S DIFFERENT ━━━━━━━━━━━━━━━━━━━━ Other screenshot tools see pixels. Hush sees the DOM. That changes what's possible: 1. Click the email, not a rectangle. Element-aware selection means the redaction snaps perfectly to the thing you actually want to hide — no fiddling with marquee handles to crop around dynamic content. 2. Smart Redact catches what you'd miss. A regex sweep across the selected subtree blacks out every email, phone, card, and key in one click. The kind of thing you only notice after you've already shared the screenshot. 3. Editable vector exports. Most tools give you a flat PNG. Hush also gives you a true-vector SVG with separate rect / text / image layers — drag into Figma and keep editing. 4. Replace, don't just hide. Smart Replace swaps real customer data for realistic-looking placeholders so the screenshot stays beautiful for marketing while being completely safe. 5. Local-first. No account, no subscription tier, no telemetry. The extension runs entirely offline; the only outbound traffic is when you click the brand badge. ━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━ Hush does not collect, transmit, store, or sell any user data. Everything happens locally in your browser. The extension does not communicate with any Hush server (there is no Hush server) and ships with zero analytics or telemetry. Your screenshots, redactions, and saved templates live only on your device — Hush has no way to see them.
