FAQ
What happens to my price if the public price rises to $19.99?
Nothing. You keep the rate you subscribed at for as long as the subscription stays active. If you cancel and come back later, you pay the price of the day.
Is there a free trial?
No. The refund window is what stands in for one: ask within 30 days of your first payment and you get it back, no reason needed. Renewals have a 14 days window.
Does CULP change the model I asked for?
No. CULP edits the harness around Claude Code: what a turn costs in context and output tokens. The model you selected is the model that answers.
Does CULP raise my Claude limit?
No. Your limit is set by Anthropic. CULP reduces the waste inside it, so the same limit carries more work.
Which platforms are supported?
Windows, macOS and Linux, through a one-line install. State lives in ~/.culp and device authorisation lasts 180 days.
Is CULP affiliated with Anthropic?
No. CULP is an independent product, not affiliated with or endorsed by Anthropic.
One plugin, one CLI, one measured claim
CULP is a Claude Code plugin and a cross-platform CLI. It works on the harness around Claude Code: the hooks it runs, the tools it loads and the context it carries from turn to turn. It cuts what that harness costs. It does not touch the model you selected, and it does not raise a limit Anthropic set.
What it changes, it changes reversibly. MCP registrations are written to disk before they are moved, a CLAUDE.md is backed up before it is split, and a decode that cannot happen blocks the write instead of guessing at it.
Nothing is authored
A patch replaces a region that is already in your file, byte for byte. A region CULP cannot tell apart is refused by name rather than guessed at.
Nothing is destroyed
Registrations and documents are saved before they are moved or split, and one command puts them back the way they were.
Measured, not assumed
The numbers come from real sessions on real files. Where a figure depends on your own project, it is written as an order of magnitude and says so.
