Your progress, saved
v1.3August 3, 2026Finish a lab and it now counts — on any device, forever. Complete all five Start Here labs and you earn Zen I — Calm Communicator, your first badge from the book. Each lab now links back to its chapter, and if you are partway through the set, Kai saves your place on the dashboard.
Added
- • Server-side lab completion for the five Start Here labs
- • Zen I — Calm Communicator achievement (all five labs)
- • Chapter links inside every Start Here lab
- • Dashboard resume line for a partly-finished lab set
Improved
- • Kai presence and dismissed tips now follow you across devices
- • Labs page shows completion checkmarks when you are signed in
Kai gets a collection — and better manners
v1.2August 3, 2026Kai can now look like *your* Kai. Pick a starter color, then earn new looks by doing labs — never by paying. We also taught Kai better manners: you choose how present Kai is (Coach, Quiet, or Hidden), tips never interrupt you, and anything you dismiss stays dismissed. Quiet is care.
Added
- • Kai Collection: 4 starter colors + 12 earned looks (Meet Kai page)
- • Kai presence levels: Coach / Quiet / Hidden, switchable from Kai itself
- • Inline coach tips at lab checkpoints (dismissible forever)
Improved
- • All Kai animations respect reduced-motion settings
- • Quiet mode replaces the floating bubble with a labeled Ask Kai button
One lab, better name
v1.1August 3, 2026The diagnosis lab is now called "What Went Wrong?" — the name our reader panel chose. Same six prompts to fix, same gentle reveal. Old links still work.
Improved
- • Renamed Prompt Doctor → What Went Wrong? (reader-tested)
Fixed
- • Light-mode colors on dashboard and labs pages
- • Sandbox now accepts single-message requests (Prompt Diff, Gap Visualizer)
The Digital Zen era begins

Read a chapter, then come try it.
Added
- • Five Start Here labs: A.I.M. Builder, Prompt Makeover, What Went Wrong?, Keep It Going, The Sunday Reset
- • A.I.M. scoring mode (Assign / Include / Make, scored gently)
- • Digital Zen light theme across the platform, dark mode retuned
Improved
- • Landing page, dashboard, and labs index redesigned in the ebook palette
