RendrLab
Read full descriptionHide full description
Rendr is a simple, offline viewer for the React and web files you already keep on your device. Open a folder of your .jsx, .tsx, and .html files through the Files app, and Rendr renders each one in a clean, full-screen preview using a built-in React + web runtime. There is no build step, no setup, and no servers. Everything happens on your device. WORKS WITH YOUR OWN FILES Rendr reads files from a folder you choose through the Files app. It has no catalog and no store, and it downloads nothing; it only shows the files that are already on your device. • Pick any folder and Rendr lists the .jsx, .tsx, and .html files and subfolders inside it • Nested folders are supported, with a tappable breadcrumb so you always know where you are • Search within a folder and across your whole tree • Sort by name or date modified • Smart automatic icons from folder names (plus a custom icon and color for any item) • Pull to refresh to pick up new files • Add files to Rendr from other apps via the share sheet • Universal: iPhone and iPad, with a split view on iPad FULLY OFFLINE AND PRIVATE Files are rendered in a sandboxed runtime that is blocked from all network access. Nothing is uploaded, nothing is downloaded, and nothing phones home. Rendr collects no data: no accounts, no analytics, no tracking. The folder you choose is read only on your device, and the app saves just a secure bookmark and your display preferences locally. GOOD TO KNOW • Rendr is offline by design. Files that try to load remote data or call the network won't fetch anything. Rendr is for previewing self-contained files you already have, not for browsing the web. • It runs a fixed, built-in React + TypeScript + web runtime. Self-contained files render best; files that depend on external packages may not render in full. • Rendr renders your files; it doesn't edit them. Rendr is a focused, private way to preview the React and web files you already keep on your device.

AI agents don't fail because the AI isn't smart enough. They fail because nobody defined the job. AI Agent Builder Architect turns your rough idea into the precise, structured instructions a real AI agent needs: its mission, its tools, its skills, its boundaries, its voice. Describe the job once. Get an agent blueprint in minutes. Copy, deploy, delegate. WHY THIS EXISTS You've seen it happen. You ask for an agent that "handles my leads" and get something that technically responds but actually does nothing well. The problem isn't the model - it's that nobody told it what the job really is. AI Agent Builder Architect is the architecture layer that comes BEFORE the agent builder. It interviews you like a systems designer would: what's the job, which tools does it need, what should it sound like, where are the edge cases. Then it writes the agent specification you'd never have written yourself. HOW IT WORKS 1. Pick the job - personal assistant, lead generator, support triage, research, content, and more. 2. Pick its tools - 50+ integrations to choose from. 3. Describe what it should do in plain language. No jargon required. 4. Give it a voice - ten distinct tones, each with a live preview of how your agent will actually sound. 5. Review its skills - small, focused abilities the AI suggests, chained into a complete workflow. Keep, edit, or regenerate. 6. Answer a few quick clarifying questions about the details that make or break an agent. 7. The architect does the rest - a polished, complete, deployment-grade agent blueprint, ready to paste into your AI agent builder. WORKS WHERE YOU BUILD The blueprint is yours. Paste it into your favorite AI agent builder, and the app will point you to a recommended one to deploy in minutes. KEEP BUILDING, NOT JUST STARTING After the first blueprint, this becomes your agent workspace. Every agent you design is saved with its own AI chat, where each reply is another ready-to-use refinement - new skills, tighter instructions, sharper behavior. Build one agent or a whole team of them. WHO IT'S FOR 1. Founders delegating their busywork to agents instead of hiring for it 2. Marketers who want a lead-qualifying agent running by Friday 3. Support teams triaging tickets automatically 4. Freelancers and consultants shipping agents for clients 5. Anyone who's tried building an AI agent and got a chatbot instead THE PROMISE Describe the job once. Get an agent that actually understands it. There's already an AI agent that could take real work off your plate. AI Agent Builder Architect is how it finally gets built - properly.
