App profiles allow Trueears to apply a custom LLM system prompt based on which application is in focus. These commands power the App Profile configuration UI by providing a searchable list of installed applications.
On Windows, app discovery scans Start Menu .lnk shortcut files and Windows Registry uninstall keys. On Linux, it detects a curated list of popular applications by checking whether known binaries exist on the system. On both platforms, results are cached in memory at startup.

​
TypeScript interface

interface InstalledApp {
  name: string;      // Display name of the application
  exe_name: string;  // Executable filename, e.g. "Code.exe" (Windows)
  exe_path: string;  // Full path to the executable
}

​
search_installed_apps

Searches the cached list of installed applications by name. The search is case-insensitive and matches anywhere in the application name. 
import { invoke } from '@tauri-apps/api/core';

const results = await invoke<InstalledApp[]>('search_installed_apps', {
  query: 'code'
});

// results might include: VS Code, VS Code Insiders, etc.
for (const app of results) {
  console.log(`${app.name} → ${app.exe_name}`);
}

​
Parameters

​
query
string
required
The search string. Matched case-insensitively against application display names. An empty string returns all indexed applications.

​
Returns

Promise<InstalledApp[]>
​
name
string
Human-readable application name (e.g., "Visual Studio Code").
​
exe_name
string
Executable filename without the full path (e.g., "Code.exe").
​
exe_path
string
Absolute path to the application’s executable on disk.
Returns a pre-filtered list of commonly used applications that are installed on the current machine. This list is shown as quick-picks when a user adds a new App Profile. 
import { invoke } from '@tauri-apps/api/core';

const popularApps = await invoke<InstalledApp[]>('get_installed_popular_apps');

// Typical results on a developer machine:
// Visual Studio Code, Slack, Google Chrome, etc.

​
Returns

Promise<InstalledApp[]> — An array of InstalledApp objects filtered to well-known productivity applications. Only apps that are actually installed are included. The popular apps list includes applications such as:
  • Visual Studio Code / Cursor
  • Slack
  • Google Chrome / Microsoft Edge / Firefox / Brave
  • Notion
  • Figma
  • Discord
  • Zoom
  • Microsoft Teams

​
refresh_installed_apps_cache

Forces an immediate refresh of the installed apps cache. The cache is populated at startup — use this command if the user installs a new application and wants it to appear without restarting Trueears. 
import { invoke } from '@tauri-apps/api/core';

await invoke('refresh_installed_apps_cache');

// Cache is now up to date — subsequent search_installed_apps calls will reflect new installs
const results = await invoke<InstalledApp[]>('search_installed_apps', { query: '' });

​
Returns

Promise<void>

​
Usage in App Profile selection

import { invoke } from '@tauri-apps/api/core';

async function loadAppPickerData(searchQuery: string) {
  if (searchQuery.trim().length === 0) {
    // Show popular apps when the search box is empty
    return await invoke<InstalledApp[]>('get_installed_popular_apps');
  }

  // Show search results as the user types
  return await invoke<InstalledApp[]>('search_installed_apps', {
    query: searchQuery
  });
}
The returned exe_name is what Trueears stores in an App Profile and matches against the app_name field from get_active_window_info at dictation time.
