Build Your Own Tools
The check you keep doing by hand, as a tool
Describe what you want in a sentence. Novilot writes the tool, shows you exactly what it will do and what it will cost, and then it lives in your tool grid like everything else.
A shipped tool is a guess about your book
Novilot ships around 195 tools and surfaces. Every one of them is our idea of what a novelist needs, which is fine until the thing you actually need is not on the list.
Your book has its own questions
How often each chapter mentions the sea. Whether the priest ever contradicts his own sermon. Nobody ships that tool, because it is about your book.
Checks you repeat by hand
If you have searched the same thing across your draft three times, that is a tool you have been running manually.
A menu you cannot read
More shipped tools do not help. Past a certain point a bigger grid is a harder grid, and the answer is not a longer list.
Not knowing what it will cost
A tool that spends credits without telling you first is a tool you will hesitate to use. Yours states its price before it runs.

How building a tool works
Describe it. Review the draft. Keep it (or try it first).
- 1
Say what you want
One plain sentence in Build a tool. Novilot works out a name, what the tool should do, what it needs to read, and what it should cost.
- 2
Review the draft
You see what it does, what it reads, and the price before you keep anything. Change details if you want the full form.
- 3
Try it, then keep it
Optional: run once on the project you are in. When it looks right, keep it. Arithmetic tools cost nothing to try.
- 4
Use it like any other tool
It joins your grid, it can be pinned, its results save and re-open free, and it is there in every project you own.
Where your tools sit
Questions, answered plainly
Open Build a tool, describe what you want to know about your book, and Novilot drafts the rest: name, what it does, what it reads, and what it costs. Review that, then keep it. You can change the details any time. See the step-by-step guide with a screen recording if you want a walkthrough.
Whatever it says on the button before you press it. A tool that reads your chapters is priced by length, about 1 credit per 10,000 words; one that only reads your story bible or outline is a flat credit. The number on the card, the number on the button, and the number you are charged all come from the same place.
Yes. If what you asked for is arithmetic (a count, a ratio, a length, a frequency), Novilot builds it as a measurement instead of an AI tool. Those run instantly, cost nothing, and give the same answer every time. We do not spend your credits on a sum.
Only what you let it: a per-chapter digest of the manuscript, a chapter index, your story bible, the characters the draft established, or your outline. You choose when you build it, and that choice is what sets the price.
No. A tool you build reads and reports, exactly like the tools we ship. It cannot edit chapters, and its output goes only to you.
Yes, and that is the point. It appears in your tool grid, it can be pinned, its results are saved so re-opening one is free, and it works across every project in your account.
