Math & Numbers

Calculate trigonometric functions (sin, cos, tan)

Finance

Split bills by items with individual amounts and custom tip percentages per person

Finance

Calculate VAT (Value Added Tax) for purchases and sales

Data Processing

Format and beautify VBA code for better readability

Text Processing

Run explainable local tokenization, sentence splitting, stopword, lemma, stem, entity and n-gram annotation with JSONL or CoNLL export.

Text Processing

Compute MD5, SHA-1, SHA-256, SHA-512, and CRC-32 hashes of any text in one shot. Get both hex and Base64 digests over the UTF-8 encoding.

Text Processing

Audit a document against a glossary/forbidden list for variants, case, abbreviation first-use, and optional AI contextual misuse

Math & Numbers

Compute engineering tensile strength σ_uts = F_max/A₀, yield strength σ_y = F_y/A₀ (optional), and the yield ratio σ_y/σ_uts from a uniaxial tension test. Forces in kN, area in mm² → stress in MPa. A₀ is the original cross-section. Yield ratio <0.55 high ductility, 0.55–0.85 moderate, >0.85 low ductility.

Development

Generate theme.extend.colors for tailwind.config.ts from HEX colors, with WCAG contrast levels and optional dark mode.

Astronomy

Compute telescope optics for visual astronomy: magnification, true field of view, focal ratio, exit pupil, limiting magnitude, Dawes/Rayleigh resolution and useful-magnification range. Enter aperture, telescope focal length, an eyepiece focal length and its AFOV (metric mm or imperial inches), pick a target (deep-sky, planetary, lunar or terrestrial), and get a scaled field-of-view overlay plus target-specific advice on exit pupil and framing.

Health

Estimate BMR, TDEE, ideal weight, and macro splits for weight loss, maintenance, or muscle gain

Math & Numbers

Convert terabytes to tebibytes with decimal vs binary interpretation, alternate-system comparison, and network-speed-aware transfer estimates
