About MeretAI

MeretAI is a free calculator site for everyday jobs: paint coverage, recipe scaling, fuel cost, grades, room area, and dozens more. Open a tool, enter your numbers, get a clear result with the formula underneath.

What this site is

• Tool-first. The calculator is the page. No sign-up wall, no lead magnet, no AI chat pretending to do math.
• Honest math. Every tool shows inputs, live results, the formula, assumptions, and worked examples. Numbers come from deterministic formulas in your browser, not from a model guessing.
• Built for real tasks. Home projects, cooking, gardening, travel, pets, study, photography, and cars. Short guides sit next to tools when a formula needs context.

What this site is not

• Not a marketing blog or SEO article farm.
• Not professional engineering, medical, legal, or financial advice. Results are estimates. Read the assumptions on each tool before you buy paint, book a trip, or trust a grade map.

How we ship tools

• Prefer fewer solid calculators over a pile of empty stubs.
• Fixture tests check inputs against expected outputs when a formula changes.
• If something looks wrong, tell us on the Contact page. Formula corrections get priority.
