<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.

Guyanonymous' Wildcard Prompt Studio

# Guyanonymous' Prompt Studio: ChangelogFrom v1 to v3 (earlier versions were called Offline Wildcard Prompt Studio). Newest changes are at the bottom of each section's list; versions run oldest to newest.---## v1: the rewriteThe first full rewrite of the original Gemini-generated prototype, keeping its look and headings but rebuilding how it works.Core- Single offline HTML file. A content-security rule blocks every network request, so nothing can be uploaded.- Scans a folder of <code>.txt</code> wildcard files (with subfolders) and lists them.- Template editor with <code>__filename__</code> tags, autocomplete when you type <code>__</code>, and green or red highlighting for found or missing files.- Drag a file name into the prompt, or use the + button or double-click to insert its tag.- Live sample with every nested wildcard resolved to a random line, using a seeded random generator so a seed always reproduces the same sample.- Click a coloured part of the sample to re-roll just that part.- Save and open templates as <code>.txt</code>. Save the evaluated sample as a single paragraph with no line breaks.- Batch export of up to 1,000 random prompts, each with a new seed, with optional duplicate skipping and optional reproducible seeds.- "All possible prompts" export when the template uses exactly one wildcard, with a combination counter, a line cap and optional duplicate removal.- Separate remembered folders for wildcards, templates, samples, batches and all-prompts exports (saved in the browser, re-allowed on reopen).- Right-hand panels: output options, batch card, all-possible card, checks and a resolution trace.- Optional inline choices <code>{a|b|c}</code>, optional comment lines starting with <code>#</code>, tidy spacing and commas, Windows line endings option.- In-app wildcard file viewer and editor with Save.- Fallbacks for browsers without folder access (folder picker, Downloads).---## v2.0: version 2 and sizingChanged- Larger, scrollable sample panel. The Prompt Template editor and the Sample panel share the centre column's height equally, and both scroll when prompts get long.- Removed the 1,000-file display limit in the left wildcard list.- Labelled the app version 2 in the title and header badge.Fixed- Wildcards not appearing after loading a saved prompt. The cause was that the linked folder was the output folder rather than the wildcard folder; the guidance and checks now make that clearer.- A mistaken rebuild that dropped the right-hand information panels was thrown away. Version 2 was rebuilt from the file where the features worked, changing only the sizing of the centre panels.---## v2.1: sample breakoutAdded- Wildcards nested inside wildcards can open up in the Sample panel, showing the parent tag and every wildcard inside it (for example <code>__body__</code> opening into <code>__head__</code>, <code>__torso__</code> and <code>__limbs__</code>).- Each opened part shows its tag name and the text it supplied.- A small arrow on every part opens or closes it, and the state stays until you change it.- Expand all, Collapse all and a Levels control.- Colour by parent: parts called by the same wildcard share a colour (switchable back to colour by depth).---## v2.2: peek in the template editorAdded- Click inside a green tag in the template editor and a ▸ button appears at the right edge of that line.- It opens a panel with the file's lines, a filter box, and a marker for the line used in the current sample.- Replace swaps that one tag for the line you choose, and Undo restores it.- Works for nested wildcards too: replace <code>__body__</code> with a snippet that still contains tags, then keep drilling in.Changed- The button sits in a gutter at the edge of the editor so it never covers text.- Autocomplete no longer pops up when you click inside a finished tag.---## v2.3: adjustable layoutAdded- Drag the edge of the left panel to resize the wildcard list, which also resizes the middle column. Double-click the edge to reset.- Wrap long names option so long file names show in full instead of being cut off, plus tooltips on rows.- Drag handles between the three centre sections (Prompt template, Sample, Exactly what gets saved) to adjust their heights.- Sizes are remembered between sessions, can be nudged with the keyboard, and are kept within limits so nothing disappears.---## v2.4: reusable picks, locks and weightsAdded- Reusable picks. <code>${name=__a__ __b__}</code> picks once and prints nothing. <code>${name}</code> prints the same value everywhere. <code>__file$name__</code> picks, remembers and prints in one go. Definitions can be anywhere in the template, and wildcard files can use <code>${name}</code> too. <code>$$</code> gives a literal dollar sign.- Remember… button: select text or tags in the editor, name it, and the app writes the definition and the use for you.- Editor colouring for variables, a red mark for undefined names, and autocomplete for <code>${</code>.- Remembered values strip above the sample, with re-roll, lock and choose-a-line buttons for each value.- Right-click menu on any part of the sample: re-roll, lock, choose a specific line from a filterable list, copy text. Locks and chosen lines survive Roll new sample, with Unlock all to release them.- Weighted lines: <code>3:: text</code> in wildcard files and inside <code>{…}</code>, with <code>0::</code> switching a line off.- Pick several: <code>{2-3$$, $$a|b|c}</code> and <code>{2$$, $$__file__}</code> choose different options and join them.- New checks for undefined, unused and twice-defined variables.- On/off checkboxes for the variable and weight syntax, so prompts with a literal <code>${</code> still work.- Counts and the all-possible export treat a reused value as a single choice, and every enumerated prompt keeps that value consistent.Fixed- Pressing Enter in a name prompt no longer leaks a line break into the editor.---## v2.5: models, exports, library and projectsAdded: model and length- Model profiles with an estimated token gauge under "Exactly what gets saved", showing the recommended length and hard cutoff.- Eighteen starter profiles across CLIP tag models, anime tag models, T5 natural-language models, LLM-encoder models, hosted models and video. Each is marked verified, estimate or unverified.- A Frontend setting (ComfyUI, Forge/A1111 or other) that changes how long prompts are interpreted, including 75-token chunk counts for CLIP models.- Manage… window: edit any profile, save it under a new name, copy or delete a profile or a whole family, import and export profiles, and revert to the originals.- Calibrate… to teach the counter from the token count your own tool reports.- Apply recommended options and Check length over 200 rolls, which reports shortest, typical and longest prompts and how many pass the limits.Added: output shaping and exports- Prefix, suffix and negative prompt fields, added to every copy, save and export, and able to contain wildcards.- Option to remove <code>(word:1.2)</code> weights for models that ignore them.- Batch export formats: text, CSV or JSON, with each prompt's seed and the lines that were picked.- Split every N prompts into numbered files, and an optional matching <code>_negative</code> text file.- A length summary after each batch.- Sweep one wildcard: one prompt per line of a chosen wildcard while everything else stays random, with an optional repeat count.Added: history and library- History: the last 60 samples, plus ★ Keep favourites that store their template. Restore brings back the template, seed, locks and chosen lines.- Library: search every line of every file, a health check (empty files, missing references, loops, duplicate and near-duplicate lines, unbalanced braces, very long lines, unused files), and where-used.- Remove duplicates in the file viewer.- Optional rescan of the wildcard folder when you return to the window, which never interrupts an unsaved edit.Added: tabs, versions and projects- Template tabs, each with its own prefix, suffix, negative prompt and model. New and Open now use tabs instead of discarding your work.- Versions…: autosaved and named versions with a compare view and restore.- Projects: save and reopen whole sets of tabs and output settings, and export or import them as files.- Tabs and the draft are restored when you reopen the app.Changed- Save dialogs and downloads now choose the right file type for CSV and JSON.- The all-possible export applies prefix, suffix and weight handling.- Help window updated for every new feature.Documents- A user guide and a ready-to-post share text now ship with the app.---## v3: renamed, collapsible panelsChanged- The app is now Guyanonymous' Prompt Studio, in the page title, header, and exported JSON.- File renamed to <code>guyanonymous_prompt_studio_v3.html</code>.Added- Every card in the right-hand column collapses to its title bar when you click the title (or press Enter on it), so unused tools stay out of the way.- Collapse all and Expand all buttons at the top of the column.- Collapsed or open states are remembered between sessions.---## Known limits- Token counts are estimates until calibrated, because exact tokenizers need large vocabulary files that an offline page does not include.- Several model limits are starting points from research and community reports, marked estimate or unverified. Test them in your own setup.- History, versions, favourites, projects and tabs live in the browser's own storage. Export projects you care about, since clearing site data erases the rest.
