Chapter-aware AI—not a detached chat window
Connect OpenRouter when you want help. Chapter Chat and Blocs use the open chapter and codex. Action inserts text only after you approve. Turn AI off and the studio is unchanged.
Manuscript software first, AI second
Many AI fiction tools price bundled generation into the subscription. Blocwrite charges for the studio—chapters, codex, reader links, export—and lets you attach OpenRouter when you want Chat or Blocs. You choose the model; usage bills through your provider, including free tiers where available.
If you are weighing Sudowrite (generation-first) against Novelcrafter (BYOK power user), Blocwrite sits between: full manuscript workflow with lighter setup and preview-first Blocs.
With AI enabled
- Chapter Chat — discuss pacing, dialogue, and reveals for the chapter on screen
- Action — insert accepted lines into the draft
- Blocs — type \\ for Idea or Scene assists; preview before accept
- Proofread — grammar and line-level help on a selection
What we do not do
- Auto-rewrite whole chapters without your confirmation
- Train models on your manuscript
- Require AI to draft, share, or export
