Photo Grid for Sketch
Handler is a vibe marketing agent for app marketers. It helps app teams find outlier TikToks, understand what makes them work, and turn proven patterns into clearer creative direction. Todayโs launch focuses on Handler and TikSpy: research winners faster, reduce manual scrolling, and know what to test next.
OnlineGridMaker is a free browser-based tool that adds customizable grid overlays to any image โ designed specifically for artists, illustrators, art students, and anyone who practices drawing from reference photos.
Most grid tools are either too basic (fixed grid size, no customization) or require downloading desktop software. OnlineGridMaker runs entirely in your browser โ no install, no signup, no image uploads. Your photos stay on your device.
Grid Overlay โ Add precise grids to any image with full control over rows, columns, line color, line thickness, and opacity.
Perspective Guides โ Built-in 1-point and 2-point perspective tools for accurate architectural and object drawing.
Cell Labels โ Optional row/column numbering for easy reference when transferring your sketch to paper or canvas.
Instant Download โ Export your gridded image as PNG or JPG and start drawing right away.
100% Local Processing โ All rendering happens in your browser using HTML5 Canvas. Your images are never uploaded to any server.
Completely free. No premium version. No signup required. Unlimited use.

Handler's answer
Handler is built specifically for app marketers who want to find what is already working on TikTok. Instead of guessing content ideas, Handler helps teams discover outlier TikToks, understand winning patterns, and decide what to test next.
OnlineGridMaker's answer:
-Unlike most grid tools that only offer basic square grids, OnlineGridMaker combines customizable grid overlays (adjustable rows, columns, color, opacity) with perspective guides for 1-point and 2-point drawing. It also offers optional cell labels (A1, B2 style). Everything runs 100% locally in the browser โ no image uploads, no signup, no data ever leaves your device.
Handler's answer
Handler is focused on TikTok research for app growth, not generic social media management. It helps marketers move faster from โwhat should we post?โ to clear creative direction based on real winning TikToks.
OnlineGridMaker's answer:
-Most alternatives either require installing software, force you to create an account, or upload your images to a server. OnlineGridMaker is completely browser-based, free forever with no premium tier, and processes everything on your device. Just open the page, upload a reference image, and start gridding in seconds. It's faster, more private, and zero friction compared to desktop apps or account-gated web tools.
Handler's answer
Handler is made for app founders, growth marketers, mobile app teams, indie app builders, and agencies that use TikTok to grow consumer apps.
OnlineGridMaker's answer:
-Artists, illustrators, art students, and hobbyists who practice drawing from reference photos โ especially those learning proportion, composition, and perspective. Also useful for architects, designers, and educators who need quick grid overlays for teaching or planning purposes.
Handler's answer
Handler was created because app teams spend too much time manually scrolling TikTok trying to understand what content works. We built it to make TikTok research faster, clearer, and more repeatable for app marketers.
OnlineGridMaker's answer:
-Built by an independent developer who noticed that most free grid tools were either too basic (fixed grids only) or required downloading software. The goal was simple: a professional-grade, free grid overlay tool that respects user privacy by processing everything locally in the browser. No tracking, no uploads, no strings attached.
Handler's answer
Handler uses AI analysis, TikTok content research, video metadata extraction, creative pattern detection, and a web-based dashboard to help app marketers find and understand winning TikToks.
OnlineGridMaker's answer:
-Pure HTML, CSS, and JavaScript โ no frameworks, no backend, no dependencies. Hosted as a static site on Cloudflare Pages for global CDN delivery. The tool uses the HTML5 Canvas API for rendering grids and generating downloadable PNG images client-side.
Handler's answer
Handler is currently early, so we are not publishing customer names yet. The product is built for app founders, consumer app teams, growth marketers, and agencies working on TikTok-based app growth.
