Tools guides

Tool roundups age badly, so the ones here get maintained rather than reposted: when a tool changes its pricing or drops a feature, the review changes too, and the updated date at the top means it. The comparisons test the boring things that decide real projects: whether the export survives a KDP upload, what happens to your manuscript when you cancel, and who owns the output. For the head-to-heads against specific tools, the comparison pages go deeper than any roundup can.
