AI Workspace
Prompt engineering and AI output tools that run entirely client-side. No model ever sees your prompts.
Prompt Tools
Format, optimize, template, and manage AI prompts — deterministic text tools, no AI APIs, nothing uploaded.
Prompt Formatter
Editor's choiceClean and normalize AI prompts: strip invisible characters, trim whitespace, collapse blank lines, normalize list markers and headings — all in your browser.
Prompt Optimizer
Editor's choiceClarify, organize, and review AI prompts locally — normalize whitespace, detect sections, flag ambiguity and repetition, and see every change before you copy.
Prompt Cleaner
Editor's choiceRemove invisible characters, encoding artifacts, and copy/paste noise from prompt text — without rewriting a word. Local, deterministic, privacy-preserving.
Prompt Template Builder
Editor's choiceWrite reusable prompt templates with {{variable}} placeholders, set defaults and sample values, preview the filled result — entirely in your browser.
Prompt Variable Builder
Editor's choiceExtract, inspect, and fill {{variables}} from any prompt template — occurrence counts, line references, duplicate detection, missing-value warnings, rename mapping, and a live preview. No upload, no AI call.
Prompt Library
Editor's choiceThe only prompt library with built-in variable fill, limitations disclosure, and one-click export — 60+ curated patterns across 19 categories, zero account, zero tracking.
Prompt Compare
Editor's choiceSide-by-side and inline diff for two prompt versions — added, removed, and unchanged lines with word-level highlights, all locally in your browser.
Prompt Markdown Formatter
Editor's choiceClean up Markdown syntax inside AI prompts — normalize headings, lists, blockquotes, and spacing while preserving code blocks, placeholders, links, and escaped text.
Prompt JSON Formatter
Editor's choiceDetect, validate, and format JSON blocks embedded inside any prompt — surrounding prose and template variables preserved exactly.
Prompt Token Estimator
Editor's choiceCount characters, words, and estimated tokens in your prompt — check context headroom and reserved output against 17 model profiles, entirely in your browser.
Prompt Naming Generator
Editor's choiceTurn any prompt text into several candidate names instantly — deterministic local rules extract headings, task lines, and section labels to suggest Descriptive Title, Short Title, Action-Oriented, kebab-case, snake_case, and PascalCase names. All local, no model receives your prompt.
Prompt Version Manager
Editor's choiceSave named prompt snapshots, compare revisions line-by-line, restore earlier versions, and export your session history — all in your browser, nothing uploaded.
AI Output Tools
Clean, format, and de-markdown AI responses — three distinct jobs, all running entirely in your browser.
AI Response Formatter
Editor's choiceNormalize heading spacing, list markers, paragraph gaps, and trailing spaces in raw AI responses — preserving all wording, code, citations, warnings, and URLs. Formatting only; no semantic changes.
AI Output Cleaner
Editor's choiceConservatively detect and review conversational wrappers in AI responses — openers, closers, answer labels, and duplicate lines. Accept each suggestion individually before anything is removed. No rewriting, no upload.
AI Markdown Cleaner
Editor's choiceConvert Markdown-heavy AI responses to plain text or lightly structured text — strip headings, emphasis, links, and list markers while preserving code blocks, citations, warnings, and substantive wording. No upload, no rewrite.
