Check a blend you already have
Paste a couple name or ship name you drafted yourself, or found somewhere else, and this traces it back to its two source names. It shows which fragment came from which name, how much of each one survives, and what a reader has to work through in the spelling.
Source names are optional. Without them the check reports spelling only.
When this is the right tool
The blender on the homepage starts from two names. This one starts from the answer. Use it when somebody has already suggested a blend, when a fandom tag exists and you want to see how it was put together, or when you invented something yourself and want a second opinion that is not a person being polite.
It is also the fastest way to compare two candidates you are stuck between. Run each one, look at the coverage figures side by side, and you will usually find one of them is quietly dropping most of one name.
How the trace works
The checker looks for the longest run at the start of your blend that matches the start of either source name, then looks for the longest run at the end that matches the end of the other one. That is the same shape the blender builds, so the trace can recognise anything the blender could have produced, plus most blends people make by hand.
What it cannot recognise is a blend built from the middle of a name, or one where the spelling has been changed to smooth the join. Those are legitimate choices and the software has no way to follow them. If your blend comes back untraceable, that is worth knowing on its own, because a reader is in the same position.
What the report will not tell you
It has no opinion. It cannot hear the blend, does not know what the name means to anyone, and has no idea whether a community already uses something different for the same pairing. The methodology page sets out every measure in full, and the blind name test covers the part that needs a human.
Common questions
What does the name blend checker do?
It takes a blend you already have and traces it back to two source names, showing which piece came from each and how much of each name survives. It reports spelling structure only, and everything runs in your browser.
Do I need to enter the source names?
No, but the check is much more useful with them. Without source names it can only report spelling issues such as consonant runs and length. With them it can tell you how much of each name a reader could actually recover.
Why does it say my blend cannot be traced?
Because neither source name matches the start or the end of the blend. That usually means the spelling has drifted, or the pieces used come from the middle of a name, which readers find very hard to recover.
