<h1 id="guyanonymous'-prompt-studio-v3">Guyanonymous' Prompt Studio v3 </h1>A single-file, fully offline prompt builder for wildcard files.I built this for my own ComfyUI / Forge Neo workflow and it grew into something worth sharing. It's one HTML file. Open it in Edge or Chrome on Windows, point it at your folder of <code>.txt</code> wildcard files, and design prompts with a live preview. No install, no server, no account, and it cannot upload anything (the page blocks every network request).<h2 id="why">Why</h2>Wildcard folders get huge and nested, and it's hard to know what a template will actually produce, which wildcard picked what, or whether a prompt has blown past your model's token limit. This shows all of it as you type.<h2 id="what-it-does">What it does</h2><ul><li>Scans a folder (and subfolders) of <code>.txt</code> wildcards, with no file limit, a filter, and resizable panels</li><li>Template editor with <code>__file__</code> tags: autocomplete, drag-and-drop, green/red validity, and a peek button that shows a file's lines and swaps the tag for one you choose</li><li>Live sample with every nested wildcard resolved. Open any part to see which sub-wildcard supplied what</li><li>Click a part to re-roll just that part. Right-click to lock it, or pick an exact line from the file</li><li>Reuse one pick everywhere: <code>${hero=__names__}</code> then <code>${hero}</code> (great for names and text overlays), or <code>__names$hero__</code></li><li>Optional weights (<code>3:: text</code>), inline choices <code>{a|b|c}</code>, and pick-several <code>{2-3$$, $$a|b|c}</code></li><li>Model profiles with a token gauge (recommended length vs. hard cutoff), calibration, editable limits, and a "check length over 200 rolls" report</li><li>Prefix, suffix and negative prompt, and it strips <code>(word:1.2)</code> weights for models that ignore them</li><li>Saves the sample as one paragraph. Batch export of up to 1,000 random prompts (new seed each) as TXT, CSV or JSON, with split files and a matching negative file</li><li>Sweep export: every line of one wildcard while the rest stays random</li><li>"All possible prompts" export for one wildcard (reused picks counted once)</li><li>History, favourites, library search, health check (missing refs, loops, duplicates), where-used, tabs, autosaved versions and projects</li><li>Collapsible tool cards, so the right-hand column shows only what you need</li><li>Remembers separate folders for wildcards, templates, samples, batches and exports</li></ul><h2 id="how-to-start">How to start</h2><ol><li>Open the <code>.html</code> file in Edge or Chrome</li><li>Click Choose folder… and pick your wildcard folder</li><li>Type a prompt and use <code>__</code> for suggestions</li><li>Ctrl+Enter for a new sample, Ctrl+S to save the template</li></ol>The included guide covers everything in about five minutes.<h2 id="version-history">Version history</h2><ul><li>v3: Renamed Guyanonymous' Prompt Studio. Every right-hand card collapses to its title bar (with Collapse all / Expand all, remembered between sessions).</li><li>v2.5: Model profiles with a token gauge; prefix, suffix and negative prompt; TXT/CSV/JSON batch export with split files and a matching negative file; sweep export; history and favourites; library search, health check and where-used; template tabs, autosaved versions and projects.</li><li>v2.4: Reusable picks (<code>${name=__a__}</code>, <code>${name}</code>, <code>__file$name__</code>) with a Remember… button and a values strip; right-click to lock a part or choose an exact line; weighted lines; pick-several.</li><li>v2.3: Drag-to-resize left panel and centre sections, wrap long file names, sizes remembered.</li><li>v2.2: Peek button in the template editor: see a wildcard's lines and swap the tag for one of them.</li><li>v2.1: Nested wildcards open up in the sample (<code>__body__</code> → <code>__head__</code>, <code>__torso__</code>, <code>__limbs__</code>) with Expand all, Collapse all, Levels and colour by parent.</li><li>v2.0: Larger scrolling sample panel sharing height with the editor; no limit on the file list.</li><li>v1: First full rewrite: offline folder scan, live nested sample, seeded re-rolls, save/open templates, one-paragraph sample save, batch export, all-possible export, separate remembered folders.</li></ul><h2 id="good-to-know">Good to know</h2><ul><li>Token counts are estimates until you calibrate them with your own tool's number, and model limits are editable starting points (some unverified), not guarantees</li><li>History, versions and projects live in your browser's storage. Export projects you care about</li><li>Use Edge or Chrome for remembered folders and saving straight into folders; other browsers fall back to Downloads</li></ul>Free to use and share.
