        How to use Prompertize

        What Prompertize does

        Prompertize turns a rough request into a structured AI prompt before you copy it. It helps you define the task, background, voice, audience, format, guardrails, and evidence boundaries so ChatGPT, Claude, Gemini, Copilot, and other AI tools have a clearer brief.

        Prompertize never sends your prompt anywhere by itself. Copy places the prompt on your clipboard, and you paste it into the AI tool of your choice. The Prompertize browser extension adds one-click insert on supported AI sites. You still decide when to send.

        Fast workflow

        1. Use Quick mode when you have a rough idea and want Prompertize to shape it.
        2. Use Pro mode when you want full control over each framework field.
        3. Pick a Framework, Target AI, and optional Recipe.
        4. Fill the starred fields. Optional fields improve precision but are not required.
        5. Review Readiness, Safety, and the Before And After preview.
        6. Click Copy, then paste the prompt into your AI tool.

        Modes

        Easy Mode

        Best for less technical users. It hides advanced controls, keeps one large request box, and lets the user choose a simple recipe. Prompertize still adds structure behind the scenes.

        Quick Mode

        Best for everyday use. Paste a loose request, notes, source text, or an unfinished prompt. Prompertize combines it with your selected framework, recipe, target AI, voice, and response format.

        Pro Mode

        Best for important work. You fill the framework fields directly, which gives you tighter control over context, objective, constraints, examples, output shape, and system-level behavior.

        Token impact

        A structured prompt may use more input tokens than a rough request. The savings usually come from fewer clarification turns, fewer rewrites, and more focused model responses.

        Prompt Tokens

        The rough request is often shorter. The Prompertized prompt adds structure, field labels, constraints, examples, and output instructions, so it may be longer.

        Iteration Savings

        The value is avoiding back-and-forth. Clear context, objective, audience, response format, and guardrails reduce the chance that you need to correct or rerun the answer.

        How To Read The Metric

        A future Token Impact panel should compare rough tokens, structured prompt tokens, and estimated retry tokens avoided. Treat it as guidance because each AI uses its own tokenizer.

        Best Way To Save Tokens

        Keep context relevant, remove repeated notes, use a precise response format, and ask for the exact deliverable instead of asking the model to infer what matters.

        Prompt frameworks

        CO-STAR

        Context, Objective, Style, Tone, Audience, Response. Use it when you need a complete prompt brief with a clear situation, task, voice, reader, and output format.

        RACE

        Role, Action, Context, Expectation. Use it for professional tasks where the AI should act in a specific role and satisfy a concrete quality bar.

        RISEN

        Role, Instructions, Steps, End goal, Narrowing. Use it when the task needs careful boundaries, ordered reasoning, exclusions, or compliance-style constraints.

        CRAFT

        Context, Role, Action, Format, Tone. Use it for deliverables such as reports, emails, plans, summaries, briefs, and polished business writing.

        TAG

        Task, Action, Goal. Use it for short prompts when you need speed and only want to specify what to do and what success looks like.

        Custom

        Define your own framework name and rules. Use it for team templates, compliance templates, research methods, teaching formats, or any repeatable prompt structure.

        NIST SP 1353 IPD uses CO-STAR in illustrative AI prompt examples for CSF 2.0 analysis and reporting. NIST states those examples are not endorsements.

        Core fields

        System Prompt

        Persistent instructions for how the AI should behave. Use it for policies, evidence rules, refusal boundaries, persona, or output discipline. Save reusable versions in System Prompt Memory.

        Context

        Background the model needs: source text, facts, business situation, constraints, assumptions, definitions, stakeholders, and what has already happened.

        Objective, Task, Action, Or End Goal

        The exact work you want done. Strong objectives use action verbs and define success: summarize, compare, draft, classify, explain, generate, audit, plan, transform, or critique.

        Role

        The expert lens the AI should use, such as project manager, teacher, cybersecurity analyst, product designer, reviewer, editor, or data analyst.

        Style

        The writing or presentation style: executive memo, technical documentation, plain-language explainer, academic, social post, creative direction, or your custom style.

        Tone

        The emotional and professional register: concise, friendly, formal, persuasive, empathetic, critical but fair, humorous, technical, or creative.

        Audience

        The people who will read or use the response. Examples include executives, beginners, customers, developers, students, designers, or technical experts.

        Response

        The final output format. Be specific when the answer must be machine-readable, visual, printable, presentation-ready, or ready to paste into another tool.

        Response types

        Text And Structured Outputs

        Use Markdown report, bulleted list, JSON object, table, step-by-step plan, email draft, social post, or checklist when the final answer is primarily text or structured data.

        Image Generation Prompt

        Use for prompts that will be pasted into an image model. Include subject, composition, style, color palette, lighting, aspect ratio, mood, detail level, and negative constraints.

        Logo Image Prompt

        Use for brand marks. Include brand name, symbol concept, typography direction, colors, background, usage context, variants, and a rule to avoid existing logos or trademark confusion.

        Media Prompt

        Use for broader creative assets such as banners, thumbnails, product shots, ads, mockups, posters, or campaign visuals. Specify platform, dimensions, visual hierarchy, and required text.

        Video Prompt

        Use for video generation or production briefs. Include scene order, camera movement, pacing, characters, setting, transitions, narration, duration, aspect ratio, and brand constraints.

        PDF-Ready Report

        Use when the output should become a document. Ask for title, summary, section headings, evidence, tables, recommendations, appendix notes, and clean Markdown that exports well.

        Slide Deck Outline

        Use for presentation planning. Ask for slide titles, key messages, speaker notes, charts or visuals, transitions, and a clear recommendation or closing action.

        Infographic, Storyboard, Design Spec

        Use these when another person or design tool will turn the response into a visual. Ask for layout, sections, hierarchy, callouts, colors, assets, constraints, and acceptance criteria.

        Advanced controls

        Redaction

        Use redaction before copying prompts that contain names, project codes, credentials, customer IDs, or other sensitive values. Redaction changes the generated prompt preview, not the source fields you typed. Redaction rules can contain the very values they hide, so they are kept only while this page is open and are never saved or exported.

        P2 Paste Scrub

        Turn on P2 scrub before using personal or sensitive source text. Prompertize masks common patterns locally before preview, copy, and vault save, including emails, greeting or self-introduction names, phone numbers, SSNs, card-like numbers, IP addresses, street-address-like text, DOB fields, and secret/token fields.

        Exact Phrases

        Best first choice. Add one word or phrase per line, such as a company name, unreleased product, person name, account number, or private project codename.

        Key And Key=Value

        Add key names such as password or api_key to redact values after separators like colon or equals. Add an exact pair such as customer_id=12345 when only one value should be masked.

        Regex Patterns

        Use only for advanced matching. Prompertize runs regex locally, limits pattern size, skips invalid patterns, and warns you when a pattern is skipped. To keep the page responsive, patterns that can backtrack badly are refused: repeated groups containing | or another repeat, backreferences, lookarounds, and more than one open-ended + or * (use bounded repeats such as {1,64}). Regex rules do not run on text longer than 20,000 characters; you will see a warning, and exact phrases and keys still apply.

        Delimiter Format

        Markdown headings are easiest to read. Hash sections are compact. XML tags are useful when you want very explicit boundaries around context, instructions, examples, or data.

        Guardrails

        Add rules for what the AI must not invent, what sources it can use, what topics are out of scope, and when it should say it does not have enough information.

        Ask When Details Are Missing

        Use this when wrong assumptions are costly. The generated prompt tells the AI to ask clarifying questions instead of guessing when required details are missing.

        Step-By-Step Process

        Use this for multi-part work. Provide the process you want followed, such as inspect source, extract facts, compare options, identify risks, then produce final recommendations.

        Variable References

        Use named intermediate outputs like [KEY_FACTS], [RISKS], [OPTIONS], or [FINAL_RECOMMENDATION] when you want the AI to organize work before the final answer.

        Dataset Analysis Notes

        Use this for spreadsheets, exports, logs, surveys, or tabular data. Include column names, definitions, filters, missing-value rules, and calculation limits.

        Ask For Data Separately

        Use this when the instruction and the dataset should stay separate. The generated prompt asks the AI to wait for the data before analyzing it.

        Examples

        Add good input-output examples, style examples, or counterexamples. Examples help the model match format and quality more reliably than abstract instructions alone.

        Saving and reusing work

        System Prompt Memory

        Use for reusable behavior rules, such as evidence-only answering, JSON output discipline, brand voice, or review standards. Selecting a memory loads it automatically.

        Prompt Vault

        Use for finished prompts you explicitly want to keep. A vault entry stores the generated prompt text (after any P2 scrub or redaction you had on), its name and tags, and the builder settings you used. It does not store the source text you typed or your redaction rules. Copy puts the saved prompt on your clipboard, and Use loads the saved settings while keeping what you are currently typing. Export or import the vault as JSON for backup.

        Readiness And Safety

        Readiness flags missing required fields. Safety flags possible sensitive data locally, such as secrets, emails, phone numbers, SSNs, credit cards, IP addresses, addresses, and confidential labels, before you paste into an AI tool.

        Privacy and security

        Prompertize stores UI settings, system prompt memory, and explicit vault items in this browser's local storage on your device. Working request text and redaction rules are not kept in the autosaved draft or in vault entries, and the request text clears after a successful copy. Use Clear all local data to remove everything this page has stored.

        This builder page includes no analytics, telemetry, ads, tracking pixels, remote prompt processing, or network calls. Its Content-Security-Policy blocks them.

        P2 scrub and custom redaction run locally. They are helpful safeguards, not a guarantee; review the generated prompt before sending it to any AI service.

        Because prompts can contain sensitive information, review the Safety panel before pasting text into any third-party AI service. Prompertize can help structure the prompt, but the destination AI site controls what happens after you send it.
