Free LLM Prompt Tools
Prepare clean, structured text for AI prompts, right in your browser. Turn a spreadsheet into text, assemble a structured prompt, merge text files, clean up AI output, or mask personal info before sending it — nothing is uploaded anywhere.
Table to Text
Paste any spreadsheet selection and instantly convert it into clean text formatted for AI prompts — as a Markdown table, flattened sentences, or a bulleted list. 100% local, nothing uploaded.
Prompt Builder
Pick a prompt-engineering template — step-by-step reasoning, few-shot examples, grounded Q&A, and more — or build your own from fully customizable fields, then export as Markdown, XML tags, or plain text.
Merge Text Files
Combine multiple .txt or .md files into one clean block of text, in the order you choose, with an optional filename heading before each — ready to paste into an AI prompt.
AI Text Cleaner
Clean up AI-generated text before pasting it into an email, document, or slide — strip Markdown symbols, invisible Unicode characters, and smart typography in your browser, nothing uploaded.
Redact & Restore
Mask emails, phone numbers, card numbers, and API keys before sending text to an AI chat, then restore the real values from the reply — the mapping never leaves your browser tab.
