Best fiction-specific AI tool. Niche but excellent.
Sudowrite is the rare AI writing tool that's actually built for a specific type of writer — fiction. The Story Engine is genuinely useful for novelists juggling plot, character, and continuity over hundreds of pages. Niche, but excellent at what it does.
