About PromoClock
PromoClock is an independent tracker for Claude's usage limits and for verified promotions across 100 popular AI tools.
How we verify
Every deal and limit change links to an official or reputable source: a help center article, an official blog post, an announcement from the company's own account or, for limit news, a reputable news report. We record the date we last checked each one and only publish codes the company or its partner program provides.
How often it updates
The site rebuilds every day. Deal status is calculated from start and end dates, so expired offers leave the live lists automatically, and the peak-hours clock runs live in your browser.
Who runs it
PromoClock is built and maintained by Onur Şendere, founder of Digiwings, a one-person digital agency in Shrewsbury, UK. It is not affiliated with Anthropic or any tool listed.
