Applications with identical display names show a muted containing-folder hint beside the name. Copies sharing the same folder show their full application bundle paths instead. Home paths abbreviate to `~`, and long hints truncate in the middle. Unique names have no hint; locations are recalculated whenever discovery refreshes.
## Calculator and unit conversion
## Calculator, unit and currency conversion
Type directly into search, as with [Raycast's calculator](https://manual.raycast.com/calculator). A recognized expression or conversion replaces application results with one **Calculator** row. Return, keypad Enter, double-click, or **Copy Answer** copies the displayed answer and dismisses the launcher, restoring the previously active application. Conversion answers include the destination unit. Application actions are disabled for calculator results; calculations do not affect launch ranking.

Arithmetic supports `+`, `-`, `*` (also `x` or `×`), `/` (also `÷`), parentheses, scientific notation, and right-associative `^` powers. Powers bind more tightly than unary signs: `-2^2` is `-4`, while `(-2)^2` is `4`. Functions are `sqrt`, `abs`, `round`, `floor`, `ceil`, `sin`, `cos`, `tan`, `log` (base ten), and `ln`; use parentheses around their arguments. Trigonometric arguments are radians; constants are `pi`/`π` and `e`. A trailing `%` divides by 100; `%` before an unsigned operand is remainder, and `mod` accepts signed operands. Percentage queries such as `52% of 900` and `20% off 80` also work.

Data abbreviations distinguish lowercase `b` (bits) from uppercase `B` (bytes): `8b to B` gives `1 B`. Decimal `KB` is 1,000 bytes; binary `KiB` is 1,024. Culinary volumes use US customary measures, not imperial measures or the 240 mL legal cup.
All calculation is offline, with no added dependencies or script evaluation. Output uses a decimal point and up to 12 significant digits; physical units generally use Foundation's native conversion precision, with exact defining Fahrenheit ratios and consistent US customary volume subdivisions. Division by zero, invalid function domains, nonfinite results, and incompatible unit families show a non-copyable error. Ordinary app names, standalone numeric literals, incomplete expressions, and unsupported syntax remain application searches. Input is bounded to 512 UTF-8 bytes and recursive parser depth below 16 to keep live search safe.

This is arithmetic and physical/data unit conversion, not full Raycast parity: currency rates, calendar/date/time-zone calculations, design units, and unrestricted natural-language math are not supported.
### Daily currency rates
Convert traditional currencies and crypto with currency codes, for example `100 USD to DKK`, `50 eur in usd`, `0.5 BTC to ETH`, or `(100 + 25) GBP as EUR`. Codes are case-insensitive; `to`, `in`, and `as` work just like unit conversions. Answers include the destination code when copied. Supported codes depend on the provider's available rates; unsupported currency codes show a non-copyable error rather than an invented rate.
Rates come from the community-maintained [currency-api](https://github.com/fawazahmed0/exchange-api), using its daily EUR-based snapshot for both fiat and crypto conversions. These are **daily rates, not live market prices**. The provider's actual snapshot date is shown in the result detail; it is a data date, not a market quote timestamp. Treat the result as an estimate, not a guaranteed trading or payment quote.
A complete, recognized currency query fetches rates over the internet without an account or API key. While loading, there is no copyable answer. Conjure keeps one snapshot in memory and reuses it across queries, with at most one fetch in flight. The next recognized currency query after the local day changes refreshes the cache; there is no background polling or fetch per keystroke. Cached answers keep their snapshot date visible, and an older cache is marked stale while refreshing. The cache is not saved across app restarts.
If fetching fails, Conjure shows a non-copyable currency error instead of silently using old or fake rates; any retained snapshot date remains visible. Change the query to retry. Application searches, arithmetic, and physical/data unit conversions still work offline.
This is not full Raycast parity: calendar/date/time-zone calculations, design units, and unrestricted natural-language math are not supported.

AppKit still provides text editing, table navigation, scrolling, application icons, controls, menus, fonts, and visual-effect materials. The background uses cached native radial gradients that fade to transparent: static soft blobs, without animations, timers, image assets, blur filters, or third-party UI dependencies. Decorative drawing does not intercept clicks. Increased-contrast settings strengthen the selection outline, and text colors are tuned for readability across the glows and selection.
