• You enter a brand or a name. The app drives Instagram through an Android accessibility service: it searches each term, opens the Accounts tab, scrolls, and collects every result.
• It can also search look-alike spellings, like the ones in the finder above, and flags each account it finds: look-alike username, risky words such as “support”, numbers standing in for letters, not verified.
• Saves an Excel file with each account’s profile photo, plus an HTML copy for phones without a spreadsheet app. The .xlsx writer is plain Java with no libraries.
• Backs off by itself: it pauses 30 to 60 seconds every 10 searches and stops after 5 failures in a row, which usually means Instagram is rate-limiting.
• Signed APKs are built by GitHub Actions, so a new version installs straight over the old one.

• A password-protected web app and a command-line version for Windows, macOS and Linux.
• Results appear as they are found and export to a CSV that opens correctly in Excel. A long search can be stopped without losing what it found.
• Two modes: Telegram’s fast server-side search, or a deep scan that reads every message to catch the keyword inside longer words.
• Works with several Telegram accounts. Sessions stay in the user’s browser; the server keeps nothing on disk, so redeploys lose nothing.
• Deploys to Render’s free plan in one click from a Dockerfile.
