This tool provides an informational analysis only and should not be considered a final or definitive verdict on your book idea.
The evaluation is generated primarily from the data you provide.
If the inputs change — such as your audience, positioning, or promise — the conclusions may change as well.
Publishing success depends on many variables outside the scope of this tool, including but not limited to:
Your existing audience and platform
Marketing strategy and execution
Pricing, positioning, and timing
Overall market conditions
Sales performance can vary significantly from one project to another. In general, authors with a larger owned audience and a clear marketing plan may see stronger results, but outcomes are never guaranteed.
Ultimately, the decision about whether a topic is worth pursuing rests with you as the author. This tool is intended to support your judgment — not replace it.
