Three tools. One taste.
Every app has a free tier on a fast hosted model. Pro on any one app is $20 a month. Suite Pro is $30 a month for Pro across all three.
Reads help you see what your draft is doing. Writes propose changes you choose to keep. Your taste carries between the three tools.
A monthly allowance, on every plan.
Free is generous. Pro gives you room for a manuscript-length pass. Suite Pro covers all three apps for less than two individual Pros.
Caps reset on the 1st of each calendar month. Manuscripts, marks, and your dictionary live in your browser and never count against any limit.

Monthly. Cancel anytime from your Stripe portal. Suite Pro is half the cost of buying each app's Pro separately.
$30 a month for all three.
Three individual Pros are $60 a month. Suite Pro is $30 a month and covers every app at Pro. The taste you teach in one tool travels with you into the next.
One subscription. Pro on Weaver, Rewriter, and R/W. Each app keeps its full Pro allowance.
Half the cost of buying each app's Pro on its own. A deliberate discount for writers using more than one tool.
The dictionary you grow in Weaver carries into Rewriter. The voice you teach in Rewriter carries into R/W. Suite Pro is one subscription for that whole pipeline.
Pick where to begin.
Free is yours on every app. No card. The model is the fast hosted one. Plenty of room to see how the tool reads your work.

Start free on R/W →Use your own provider.
Every app, on every plan, accepts a provider key you own. Anthropic, OpenAI, or Gemini. Your provider bills you directly. Monthly caps stop applying on BYOK traffic; your key, your usage. The key stays in your browser and is never sent to a Kaizen server. Switch back to hosted any time by removing the key from Settings.
BYOK is free of Kaizen charges. Costs are whatever your provider quotes for the model you choose.
About billing.
What happens when I hit a monthly cap?
The app tells you which counter is full and pauses that action until the 1st of the next month. Other counters keep working. You can also switch to your own provider key at any time and keep going on your own usage.
How does Suite Pro relate to per-app Pro?
Suite Pro is one subscription covering all three apps at Pro. If you already bought a per-app Pro and later upgrade to Suite Pro, the per-app subscription is auto-canceled and Suite Pro takes over. Each app keeps its full Pro allowance under Suite Pro; the caps are not pooled.
Can I cancel mid-month?
Yes. Pro access stays active until the end of the current billing period. After that you drop to Free on every app. Your manuscripts, marks, and dictionary stay in your browser regardless of tier.
Does BYOK count against my monthly caps?
No. BYOK is separate from hosted tiers. Your provider meters the calls; the Kaizen caps stop applying on BYOK traffic. You can mix freely: hosted on some sessions, BYOK on others.
What payments do you accept?
Stripe handles checkout and renewal. Any card Stripe supports works. The Kaizen worker never sees your card details.
