How to use
- Paste your prompt into the first box. Use Basic for quick cleanup or Smart for structure and shorthand expansion.
- Toggle Auto-format off to edit without live updates, then click Format prompt when ready.
- Use Before / After view to see exactly what changed. Copy the result into ChatGPT, Claude, or any AI tool.
- For long text, use our Text Chunk Splitter or Token Counter after formatting.
Example use cases
Pasted prompts from notes or chat
Clean up prompts copied from Slack, notes, or docs so they have consistent spacing, bullets, and readability before sending to ChatGPT.
Single-line or run-on prompts
Turn one long sentence into structured paragraphs so the AI can parse intent and constraints more reliably.
Role and task prompts
Format 'Act as…' and task instructions with clear headings and bullet points so the model follows structure better.
Before token counting or comparison
Format first, then use the Token Counter to stay within limits or the Prompt Comparison tool to A/B test versions.
Example: Before and After Prompt Optimization
See how AI prompt formatting improves structure and readability for ChatGPT and other tools.
Before (messy prompt)
After (formatted & structured)
What changed: Extra spaces were normalized, shorthand (e.g. "pls", "thx") was expanded, and the prompt was restructured into Goal / Context / Constraints so the AI can parse intent clearly. This kind of prompt optimization leads to better, more consistent AI responses.
Frequently Asked Questions
Is the AI Prompt Formatter free to use?
Yes. The AI Prompt Formatter is 100% free. There is no signup, no account, and no usage limits. You can format as many prompts as you like. All processing runs in your browser—your prompts never leave your device.
Does my prompt get sent to a server or API?
No. Formatting happens entirely in your browser. We do not send your text to any server, OpenAI, or third party. Your prompts stay private and never leave your device.
What is the difference between Basic and Smart Enhancement?
Basic Formatting normalizes whitespace, fixes spacing after punctuation, improves bullet consistency, and turns single-line prompts into readable paragraphs. Smart Enhancement does all of that plus expands common shorthand (e.g. pls → please), and for short prompts it can suggest a Goal / Context / Requirements / Output Format structure to improve clarity for ChatGPT and other AI tools.
What is the character limit?
The formatter accepts up to 50,000 characters. Input beyond that is truncated to keep the tool fast and responsive. For very long documents, consider using our Text Chunk Splitter first.
How do I get better results from ChatGPT?
Clear, structured prompts get better answers. Use the formatter to fix messy pasted text, add consistent spacing, and (with Smart Enhancement) add structure. Then use our Token Counter to stay within model limits and our Prompt Improver for clarity suggestions.
What is AI prompt optimization?
AI prompt optimization means cleaning and structuring your instructions so ChatGPT and other models understand you better. This tool helps with prompt cleaner online: fix spacing, bullets, and add a clear Goal/Context/Constraints structure to improve AI responses.
Why use a prompt formatter instead of pasting raw text?
Messy or single-line prompts are harder for AI to parse. Formatting improves readability for both you and the model, reduces ambiguity, and can surface missing context. Use our ChatGPT prompt formatting tool before sending to get more consistent, relevant outputs.
Use this free prompt formatter before sending to ChatGPT or Claude—faster edits, clearer prompts, better AI responses.
