Merge Text Files
Combine multiple files to one
Only for Mac
$4.99
Mac
New in 1.4: every option in one clear panel, and file name headers in a single click. Plus AI Prompt format with a live token count for any AI chat.
Merge Text Files takes any number of text files and combines them into one — in exactly the order you want, with exactly the formatting you need.
Drag in a handful of files or drop a whole folder. Arrange them by hand or sort them by name or date. Watch the result build live in the preview, then save it or copy it to the clipboard.
MERGE FOR AI
Switch to AI Prompt format and your files become a clean markdown document: each one with its own heading and code block, and the language picked up from the file extension. A live token estimate tells you whether the result fits in the model's context window before you paste it. Give an AI chat a whole project in one go, instead of one file at a time.
BUILT FOR REAL FILE LISTS
• Drop a folder and every text file inside is added
• Sort by name or date, in proper numeric order — Chapter 2 comes before Chapter 10
• Drag to reorder, or send a file straight to the top or bottom
• Uncheck a file to leave it out of the merge without removing it from the list
• Preview any file with Quick Look, or reveal it in the Finder
CONTROL THE OUTPUT
• Separate files with nothing, a line break, a blank line, or your own text
• Put each file’s name above its contents, or build your own header from the path, number or date
• Normalise line endings, strip trailing spaces, guarantee a final new line
• Save as UTF-8, UTF-16, ISO-8859-1, Windows-1252 or Windows-1253
READS FILES OTHER TOOLS CAN'T
The encoding of every file is detected as it is read, so a folder mixing modern UTF-8 with older Greek or Western European documents merges correctly without changing a single setting.
A PREVIEW YOU CAN WORK IN
The merged text builds live as you go, with dividers showing where each file starts. Search it with ⌘F and every match is highlighted. Edit it directly if you want to adjust something before saving — your changes are kept, never quietly overwritten.
PICKS UP WHERE YOU LEFT OFF
Your file list and all your settings come back when you reopen the app. Edit one of the source files in another app and the preview updates by itself.
WHO IT'S FOR
Writers merging chapters and drafts. Developers assembling source files for AI or documentation. Researchers combining notes, transcripts and exports. Anyone who has ever tried to do this by hand with copy and paste.
Merge Text Files is a native Mac app. No accounts, no sign-in, and nothing you open ever leaves your Mac.

A NEW, CLEARER WINDOW
• All merge options now live in a panel on the right, grouped and always visible. Show or hide it with Option-Command-I
• Plain and AI Prompt format are now side by side at the top of the panel, with a short description of each
• Copy and Save moved to the toolbar, so the preview gets the full height of the window
FILE NAME HEADERS, ONE CLICK AWAY
• New Headers option: put the file's name on its own line before each file. Choose from === name ===, --- name ---, ## name or // name
• No more setting up a custom separator just to see which file is which
MORE FILES RECOGNISED
• Dropping a folder now picks up text files without a familiar extension, such as Dockerfile, Makefile, LICENSE, .vue and .tf files
• Add Files can now choose them too
• Images, archives and other binary files are still left out
FIXES
• "End Each File with Newline" no longer adds an extra blank line to files saved with Windows line endings
• The divider in the preview now sits on the first line of each file, not on the blank line above it
