Utilities & Reference
Built-in calculators and offline security/macOS knowledge lookups.
8 tools — 8 read-only.
Read-only tools never modify anything; anything that changes your Mac pauses on an Approve card first.
calculate Read-onlyEvaluate a math expression and return the number. Supports + - * / ** % and parentheses plus functions like sqrt, log, sin, factorial.
convert_units Read-onlyConvert a value between units — length (m,km,mi,ft,in), mass (kg,lb,oz), data (mb,gb,gib,tb), time (s,min,h,day), speed (kph,mph,knot), area (sqm,sqft,acre,hectare), volume (l,ml,gal,cup,floz), energy (j,kj,cal,kcal,wh,kwh,btu), power (w,kw,hp), pressure (pa,bar,psi,atm,mmhg), frequency (hz,khz,mhz,ghz), and temperature (c,f,k).
datetime_tool Read-onlyDate & time math: the current UTC time, days between two dates, date arithmetic, weekday lookups and Unix-timestamp conversion.
text_tool Read-onlyText utilities, processed on-device: word/character/line counts, case conversion, slugify, reverse, JSON pretty-print & validation, line sorting & de-duplication and more.
network_lookup Read-onlyAnswers networking questions without touching the network: subnet/CIDR breakdowns, IP classification (private, public, reserved), well-known port names, MAC-vendor prefixes and more.
security_tool Read-onlySecurity and encoding helpers, computed locally: SHA-256 hashing, Base64/Base32/hex encode & decode, CRC32, ROT13, entropy measurement, password strength rating & secure password generation, Luhn card-number checks, JWT decoding and UUIDs.
reference_lookup Read-onlyPlain-English reference lookups — what a port number is used for, what an HTTP status code means, what a file extension is — answered instantly, no internet needed.
macos_lookup Read-onlyInstant macOS reference facts: what a privacy permission like Full Disk Access actually covers, what system folders are for, and other exact answers — deterministic, no Mac access needed.
