Write faster. Stay consistent. Finish your book with structured coaching.
Prosa is a modern writing workspace for long-form projects with built-in coaching for synopsis, scenes, story development, continuity, and revision quality. Draft in flow, organize your structure, and get clear feedback where the manuscript actually needs it.
Structure
- Part I
- Ch 1: Arrival
- Ch 2: The Letter
- Ch 3: Dusk
Coaching
Structured guidance for synopsis, scenes, story logic, and revision
Prosa is built to coach the manuscript you already have. Get focused feedback inside the synopsis, scene editor, and continuity workflow so you can think through the work without handing over the writing.
Synopsis coaching
Evaluate your synopsis, surface guiding questions, and request alternatives one field at a time.
Useful when the premise is close but the shape of the story still needs pressure-testing.
Scene coaching
Suggest scene improvements, refine a passage, and find open questions without leaving the editor.
Feedback stays anchored to the scene you are drafting instead of a generic AI chat.
Story coach
Get broader story feedback built from your current story context, not a blank prompt window.
A strong fit when you need help with direction, structure, or what a scene should accomplish next.
Continuity coach
Run continuity checks, refresh canon context, and apply supported fixes when conflicts appear.
Designed to protect timelines, character facts, and recurring story-world details.
Style & quality
Run focused quality checks to catch readability and style friction before you share or export.
Ideal for revision passes where you want clear signals without losing your voice.
Smart recommendations
Coach cards suggest the next helpful move, from creating the first scene to reviewing progress or opening the outline.
Project-level and scene-level prompts keep momentum when you are unsure what to tackle next.
How it works
From first draft to finished manuscript

Storyboard your manuscript like a working story system
Plan scenes visually, edit structure inline, and get AI guidance on pacing, POV balance, and missing story beats.
Prosa's storyboard turns your manuscript into a visual scene board. Organize chapters as columns, move scenes with drag-and-drop, and update story structure directly from the board. With built-in insights and AI suggestions, you can spot weak pacing, missing scenes, and structural imbalances before they become problems.

- Inline scene editor for summary, POV, role, intent, and notes
- Filters and color modes for POV, subplot, and status
- Bulk updates across multiple scenes
- AI suggestions for next scenes, missing beats, and structure issues
