Durability, ramp, and your easy corridor — computed from your own watch, on your own machine. With a coach that lives in the AI you already pay for and writes every decision straight back into the screen.
TRY ASKING
Normal effort, aggressive ramp — 1.29× load, 7 runs. Start of the block that ended in the Feb injury. ✓ pinned
Mile-for-mile you were under your normal effort then — you weren't running hard, you were running a lot: 7 runs, 1.29× your recent load. Intensity was innocent; volume was the aggressor.
And it starts the block that ended in your February injury. The tendons got outvoted.
Not a mockup — my actual training, synced this morning. Two apps, one conversation: the coach lives in your AI, the truth lives in Debrief. ↻ replay

No API keys. No AI bill from us. If you can open a chat, you're set up.
WHY THE SCREEN EXISTS
The graphs were paywalled. So I built them.
My watch had the data. The apps had the charts — behind a monthly fee, and the ones that mattered didn't exist at any price. Debrief computes them locally, and nothing you see costs a subscription.
DURABILITY
17weeks
How long you've absorbed load without a down week — the number that predicts breakdown before your legs do.
RAMP
1.13× chronic load
sustainable band
This week against what your body is adapted to, watched inside its band. Progress without the injury cliff.
THE EASY CORRIDOR
< 45stress/hr
42.3easy, truly62.1"easy," allegedly
Every run colored against your corridor — so "easy day" stops being a feeling and starts being a fact.
Stop being the clipboard.
Be honest — you already coach yourself with AI. Screenshot the watch app, paste it into a chat, get genuinely good advice… and then you type it into wherever your plan lives. Great coach. Terrible job for you: data entry.
EVERY WEEK UNTIL NOWscreenshot→paste→re-explain yourself, again→good advice→retype into your plan→lost by Thursday
WITH DEBRIEF CONNECTEDask→✓ already in your plan
Nothing retyped. Nothing re-explained. Every conversation starts with your whole history already in the room. You just run.
MANUAL ENTRY
0fields, ever
Runs sync from the watch. The AI drafts the review. You just argue with it.
YOUR HISTORY
1file, on your disk
SQLite. No account, no server. I don't keep your data — I don't even want it.
PRICE
$0/month, forever
First year free. If it earns a price later, you pay it once. We're all done renting software.
WHO IT'S FOR
For runners who'd rather own than rent.
This is for you if…
you want a desktop analytics dashboard you can actually read
you want your training history on your machine, not in someone's cloud
you'd rather pay once than subscribe forever
you already talk to an AI, and wish it knew your running
Probably not, if…
you want a phone-first recorder — your watch app already does that well
you're here for feeds, kudos, and segments
you're happiest with your data living on someone else's servers
The quiet math: subscription apps charge monthly because they pay monthly — servers, storage, staff. Debrief runs on the computer you already own. No overhead, nothing to pass on. That's why it can cost like a tool instead of a service.
If this sparks an idea for your own version — take it. We live in the era of bespoke software. — Dave
