How it works
Template queries built in, ready from day one
An example of adding your first search template to the fns launcher. Register a pattern once, call it with a single word.
Pick from the built-in template gallery
Choose a ready-made search template from the gallery inside fns and add it instantly — no need to build your own.
Apps · files · URLs · system settings, all in one search
Type "vs" → launch VS Code, "display" → jump to Display Settings, "wifi" → open Wi‑Fi settings. One palette, every target.
Scientific calculator built in
"1234 * 56" returns instantly. sin · cos · arctan · log · √ · π all calculate right in the search bar.
Search based on your configured query
Run the query you set up and get the corresponding search, calculator, or action right away — no screen scraping needed.
Questions.
Which sites are supported out of the box?
The launch set includes Amazon, Coupang, and AliExpress. Google Shopping is on the roadmap. Each site is a lightweight search adapter — no scraping, just constructed search URLs that open in the system browser.
Can I add my own custom sites?
Yes. Settings → Query Launcher → Sites lets you add any site with a URL template. If the site has a search URL with a query parameter (most do), you can wire it up in about 30 seconds.
Does it work offline?
The launcher UI is local and opens instantly. The results themselves require a network connection — fns loads price data from the configured sites, so an internet connection is needed for results to populate.
Is this free or part of a paid plan?
Query Launcher is included in fns. Monthly and yearly subscriptions include cloud AI/API usage. Lifetime licenses include local/on-device features, with optional cloud AI/API access available as a separate add-on.
