Your Personal Writing Coach
Adaptive lesson plans, diagnostic assessments, and rubric-based grading across 13 skill categories. Not grammar checking — craft coaching that makes you a better writer.
Seven Steps to Better Writing
A structured coaching loop — not random tips. Each cycle builds on the last.
Take the Diagnostic
Write a short piece. The coach evaluates 13 skill areas.
Your diagnostic is graded against the same rubric used for every exercise. It establishes a baseline so your plan targets the skills that need the most work.
Get Your Plan
A 30-unit curriculum adapts to your weakest areas.
The plan sequences units so that foundational skills come first. Each unit builds on the last — no random exercises.
Study the Craft
Each unit teaches a specific skill with examples from published fiction.
Lessons include annotated excerpts, craft principles, and concrete techniques you can apply immediately.
Write the Exercise
Apply what you learned. Write directly in the editor.
Every exercise has a specific prompt designed to practice the skill from the lesson. Write in the same editor you use for your manuscript.
Receive Grading
Line-level feedback against a professional rubric. No hand-waving.
Each exercise is evaluated on 4–5 criteria specific to the skill. You get a score, line-level annotations, and concrete suggestions for revision.
Revise & Improve
Rewrite with targeted feedback. See your score improve.
Revision isn't optional — it's where the learning happens. Rewrite your exercise and submit again to see measurable improvement.
Level Up
Earn XP, unlock skills, and track your growth over time.
Every graded exercise earns XP in the relevant skill category. Watch your radar chart grow as you work through the plan.
Every Dimension of Craft
The coach evaluates and teaches across all the skills that separate amateur writing from professional work.
Line-Level Grading in Action
See what rubric-based feedback looks like. Every annotation references the specific skill being evaluated.
“She walked into the room and felt sad about what had happened.”
Telling, not showing. What does sadness look like in her body? What sensory details ground this moment?
“The weight of the empty chair pressed against her chest. She gripped the doorframe, knuckles whitening.”
Strong revision. Concrete sensory detail replaces abstract emotion. The empty chair does double duty as setting and emotion.

Frequently Asked Questions
Is this like Grammarly?
No. Grammarly checks grammar. Polyz's coach teaches craft — dialogue, pacing, characterization, show vs tell. Think MFA workshop, not spell check.
How does grading work?
Each exercise is evaluated against a rubric with 4–5 criteria specific to the skill being taught. You receive a score, line-level annotations, and specific suggestions for revision.
Can I skip ahead?
The diagnostic determines your starting point. Units unlock sequentially within your personalized plan, but you can retake any completed unit.
Does the AI write for me?
Never during coaching. The coach evaluates your writing and provides feedback. The AI authoring tools (ghost text, inline editing) are separate features.
