Guide to AI Tools Calculators

These browser-based tools help you plan, draft and pressure-test the way you work with AI models, without sending anything to a model or storing your text. They suit people who use chatbots or code assistants regularly, run assistants or automations at work, teach, or write content, and who want a repeatable prompt rather than a one-off lucky result.

Write and refine a prompt

Start with a scaffolded builder for common jobs, then score and version-compare to tighten wording before you rely on it. Use the general builders when your task fits a named pattern; use the score and compare tools once you already have a draft.

Task-specific prompt builders

Reach for the builder that names your job so you don't forget the fields that make the answer useful. Pick by the deliverable: a CV, a reply, meeting notes, a lesson, a business idea, a data question or an SEO brief.

Estimate cost and fit within the context window

Use the token and cost estimator before running a large or repeated job to sanity-check spend, and the context/chunk planner when your source text may be too long for one pass. Model selection helps when you're unsure which tier the task actually needs.

Check trust, safety and privacy

Run these before you act on an answer or paste sensitive text: redact personal data first, then screen for hallucination or workflow risk, and use the quality and citation checks when the output must be defensible.

Automations and image prompts

Use the workflow simulator and risk checker when you're wiring AI into a multi-step process rather than a single chat; use the image builder and critique when your output is a picture, not text.
