JoyCraft tools
Small, sharp tools that make hidden costs visible.
JoyCraft builds small, sharp tools that make hidden costs visible. The hidden cost for course learners is time — a 20-hour course they can't afford to sit through. The hidden cost for Shopify sellers is the gap between the revenue number on their dashboard and the profit they actually keep. That's what these two tools fix, one for each problem.

CourseSpeed — get your time back from long courses
A browser extension for people who buy online courses and don't have time to sit through them. CourseSpeed pushes playback past the speeds the course platforms offer, and takes timestamped AI notes from the audio and subtitles while you watch.
- Speed controls beyond the player's — set your own pace for each lesson.
- AI notes as you watch — timestamped notes and summaries, built from the course's audio and subtitles.
- Nothing to sign up for — start using it without creating an account.
Works with courses on Udemy, Coursera, LinkedIn Learning, and Skillshare. CourseSpeed is free to start: the free version includes full speed control and AI notes.

CostPilot Pro — see the true profit on every Shopify order
A Shopify app for sellers who are tired of guessing whether a sale made money. CostPilot Pro puts each order's costs — COGS, shipping, platform fees, ad spend, refunds — next to its revenue, and shows the profit you actually keep.
- Every cost, on every order — revenue minus COGS, shipping, platform and payment fees, advertising, and refunds.
- A first snapshot from data you already have — install, authorize, and see a profit view built from your store's existing data. Add cost details whenever you're ready.
- Has a free plan — try it on your own store before you pay anything.

Choose by your situation
- You're working through online courses — long lectures, a deadline, or a certificate you want sooner — and you want speed controls the platform player doesn't give you, plus notes you can search later. Start with CourseSpeed.
- You run a Shopify store and want to know what each order actually earns once COGS, fees, shipping, ads, and refunds come off. Start with CostPilot Pro.
The two tools are built for different jobs and work standalone. You don't need one to use the other.
Built to stay small and honest
CourseSpeed lives in your browser while you learn. CostPilot Pro lives in your Shopify admin while you sell. Neither tool needs an account on this site, and the two never pool your data — there is no shared profile, and no cross-tool tracking. What we collect is listed in the privacy policy.
New tools ship as separate cards on this page. If you'd like to see one, tell us.
