YGen vs Corner Radius

You have the video idea. Give it a thumbnail that feels like your channel. YGen helps you create and refine YouTube thumbnails with AI, from the first concept to the image you save and share. START WITH AN IDEA Describe the scene, mood and headline you want. Choose a horizontal or vertical format and generate up to three variations to compare. MAKE IT YOURS Add your own photo or a visual reference. Use Character mode to place your subject in a new thumbnail concept. Import a YouTube thumbnail as a starting point for your own design. REFINE WITH WORDS Ask for changes to the text, background, colors or composition. Keep useful versions together in your gallery and return to them when you need a new direction. GET PAST THE BLANK PAGE Brainstorm concepts and titles with the creative assistant. Review AI feedback on your thumbnail's visual clarity and composition. AI feedback is guidance, not a prediction of views or click-through rate. SAVE AND SHARE Keep your creations in one gallery, save them to Photos or share them from your iPhone. Built for gaming, travel, podcasts, tutorials, reviews and channels without an on-camera host. SUBSCRIPTIONS A paid subscription is required for image generation and editing. Starter and Creator include sparks; each generated or edited image uses sparks. See the app for current prices and allowances. Subscriptions renew automatically unless canceled in your Apple account settings. No free trial is included. Use photos and reference material you have permission to use. YGen is not affiliated with YouTube or Google. Terms: https://ygen.app/legal/terms Privacy: https://ygen.app/legal/privacy

Pick the exact corner radius for a button, card, sheet, or app icon — and see it live, at real size, before you write a single line of code. Most radius decisions happen blind: you type a number, rebuild, squint, and type another. RadiusPreview turns that loop into one slider. Drag it and a real, scalable shape reshapes instantly on screen — 0 to 160 pt, uniform or corner-by-corner. Flip between Apple's continuous squircle and a true circular arc and watch the difference the way your eyes actually read it. When the shape looks right, the exact CSS, SwiftUI, or SVG is already written for you, ready to copy. WHAT YOU GET - One slider that reshapes a real UI surface in real time — no rebuild, no guessing - Copy-ready CSS, SwiftUI, and SVG code for the exact shape on screen - Independent control of all four corners for sheets, chat bubbles, and tabs - A continuous-vs-circular comparison that finally explains why one looks softer - 12 ready-made presets — card, button, pill, sheet, squircle, app icon mask and more - A saved library of your shapes, so a decided radius never gets re-litigated PERFECT FOR - iOS developers matching SwiftUI surfaces to the system look - Web and front-end developers writing border-radius by hand - Product and UI designers defining a radius scale for a design system - Anyone who has ever argued about whether 12 or 16 looks better WHY NOT JUST EYEBALL IT IN THE INSPECTOR? Because a radius of 44 pt on a 260 pt card is not the same radius on a 56 pt button, and a continuous curve at 24 does not match a circular curve at 24. Seeing both at true size, side by side, takes seconds — reworking a component after it ships takes a day. LEARN A built-in Learn section explains the nested-radius rule, how to build a radius scale, the half-height pill trick, per-corner syntax in CSS and SwiftUI, and when sharp beats soft. PRIVACY Everything runs on your device. No account, no sign-in, no ads, no tracking. It works fully offline. FULL ACCESS Premium unlocks per-corner radius control, SwiftUI and SVG code export, the side-by-side continuous vs circular comparison, and all premium presets. Available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. CSS export, uniform radius, free presets, the radius scale reference, saved shapes, and the Learn section are included without a subscription. Open the app, drag the slider until the corner looks right, and paste the code into your project.
