AI‑assisted writing,
reimagined
Go from concept to polished draft with a guided writing pipeline powered by AI. Whether you're writing a novel, screenplay, nonfiction book, or script, Proselon walks you through every stage—so you can focus on the writing, not the process.
Not another rephrasing tool
Most AI writing tools only see the paragraph you're editing. Proselon is different.
Full-project awareness
Proselon maintains a live-updating index of your entire project. Your AI collaborator can reference any character, scene, or chapter at any time — not just the text in front of you.
A real collaborator
Proselon is a freeform AI agent that understands your project's structure, themes, and voice. It can help you brainstorm, draft, outline, and revise — all with the full picture in mind.
Serious models for serious writing
Proselon is designed for the most capable AI models available — models sophisticated enough to synthesize a full-length manuscript and give you thoughtful, context-aware feedback.
Bring your own model
Proselon doesn't lock you into a single AI provider. Connect your own API key from Anthropic, OpenAI, or other providers and use the model that works best for your writing.
