MergeRight Classic (AWT) screen shot

New: Prescient Proudly introduces our MergeRight 2000 (JFC) Edition!

This new edition runs anywhere there is Java 1.2 support. Now you can run the same MergeRight Java binaries anywhere:  on Windows, Unix or other platforms supporting Java.

MergeRight is an easy-to-learn, easy-to use graphical user interface designed to facilitate merging code and text revisions.  Files containing changes are compared against one another and with a common ancestor file. Color highlights changes between files and encourages changes. The ancestor file is hidden, but easily accessible to provide contextual support for decision making.

Key Benefits

• ELIMINATES MERGING BUGS: Few people understand that the merging process itself can be the cause of many hard to find bugs; thus causing hours, weeks or months lost to testing, identifying and repairing code problems.  MergeRight compares files to find changed code, and displays the changes in a way that makes finding potential merge problems easy, and provides simple to use controls to fix and prevent those problems from winding up in the merged result file.  Where other Merge Programs automatically make changes, even when it isn't safe, MergeRight FACILITATES PROGRAMMER INTERVENTION to prevent such problems.
• BUILT-IN EDITOR, WITH POWER MERGE NAVIGATION FEATURES. Not just a difference tool, that writes half merged code into a file for you to modify further with an editor that knows nothing about the merge process -- MergeRight integrates the editor with merge navigation tools.
• BENCHMARKS PROVE ADVANCED MERGING SPEED:  In customer tests, NEW MergeRight users regularly out-perform experienced users of other merge tools -- typically completing merges in less than half the time, and with five times fewer errors.   Customers have even reported that merge work that used to take two weeks to do correctly are now done accurately in just a day.
• EASY TO LEARN, FASTEST TO USE:  Other merge tools regularly used by professional programmers require training and experience to use, and even then users often find it a lengthy tedious process to correctly do a merge and verify correctness. Many merge utilities simply automatically merge any two files, sometimes introducing serious, but often hard to find semantic programming errors.  MergeRight solves both of these problems. First, MergeRight has an advanced yet fully intuitive and familiar editor to any PC or WWW user. Second, MergeRight automates and provides data for enough of the merging process to make it the simplest and fastest program to use.  Users not only learn MergeRight quickly, but are fully proficient with the program in an average of 15 minutes.
• COMPARES 2 FILES WITH ANCESTOR:  more than just a comparison tool that can tell you what is different, MergeRight can actually tell you what changed, by comparing the two branch files with the original they were created from.
• AUTOMATIC CHANGE IDENTIFICATION: MergeRight does not require you to search an entire file for special characters just to find changes or conflicts.   MergeRight pioneered the Concordance style layout that shows you exactly what is changed side by side.  You'll never have to lock and unlock scroll bars or adjust displays to see the alternatives.  And selecting an alternative takes just a single button click.
• Easy Undo: Change your mind about which selection to include or exclude multiple times.  No need to resolve all the differences in a linear order.   Make all the change in the easiest order to ensure correctness.  Go back at any time and undo a resolution and choose to resolve the change using code from the other file.  This makes it easy to accept some changes and back out others.  And where necessary, even cut and paste, join or edit the selections to get the correct result.
• MERGERIGHT RECOMMENDS SOLUTIONS: Because MergeRight know what changed it can recommend what code changes to accept and which to reject. 
• DELETIONS STAY OUT: If someone deleted code to remove a bug, MergeRight's RECOMMENDED SOLUTIONS will help you recognize this and avoid merging in the removed code again -- thereby reintroducing the bug.
• NO PAPER DOCUMENTATION OR REPORTS NEEDED:  MergeRight is so simple to learn and use, you will learn how to use it all in less than 15 minutes -- without having to read any user manual.  Nor will you have to print out several copies of the changes in order to easily compare them.
