Fire Joker

Fire Joker is an offline tool for tidying up messy plain text, across three screens: Input, Rules and Result. On first opening, a bundled example note is shown in full, ready to clean with one tap. You can also start your own input and paste text in when you choose. Three rules do the work: trim line edges, collapse repeated spaces and remove empty lines. Each rule is a separate switch with a short explanation, and the Rules screen previews the outcome as you toggle. The Result screen shows the original and the cleaned text together for comparison. Copy the cleaned text to the clipboard on command, or switch every rule off to get the original back exactly. Nothing is kept until you save. Saved work stores the original text and your rule choices on this device, and you can reopen, edit or delete it after a confirmation. Unsaved drafts last only for the session. There are no accounts and no network features, and the clipboard is never read on its own, so Fire Joker works entirely offline.
