A Sudowrite alternative that does not centre on AI credits
Sudowrite leads with AI-heavy generation. Blocwrite is a writing studio where Assist is optional — Companion and Blocs with your key, preview before insert.
14-day Pro trial — no card required
Why authors look past credit-based AI writing
Generation tools are exciting until a long novel burns through credits—or until you realise you still need chapters, a story bible, beta feedback, and export. Blocwrite reverses the stack: manuscript infrastructure first, AI second.
How Blocwrite AI works instead
- BYO OpenRouter key — you pick the model; usage bills through your provider
- Chapter Chat — context from the open chapter and codex, not a blank chat tab
- Blocs — type
\for preview-first assists; nothing inserts until you accept - AI off is fully usable — draft, codex, share, and export without connecting a key
- Studio price — 14-day trial, then Lite £7.99/mo · Pro £10.99/mo; no bundled generation packs in the subscription
When Sudowrite may still win
If your primary goal is high-volume AI prose expansion and you are happy with credit economics, Sudowrite can be a better fit. If you want scene-aware help inside a real manuscript room, try Blocwrite.
