The first week, start to finish.
Five minutes of setup, one phone call, and one text message. That's the whole thing. Here is what each of those looks like, and what to do when Jai gets something wrong — because it will, and knowing how to correct it is most of the skill.
Day one
Sign up, and answer one question
Jai asks what you want help with — training, food, or both. That answer decides what you see from then on, and you can change it later. It never asks for anything you can't know off the top of your head: no goal weight, no body fat, no target date.
You get your own phone number
It's yours, it's not shared, and it's the whole product. Save it as a contact called Jai before you do anything else — then it works with every assistant and car dashboard you already own, because they all know how to call a contact.
Call it and do a session
Earbuds in, phone in a pocket. Jai says what's next, you say done when a set is finished, and it counts your rest out loud. If you'd rather not talk in a busy gym, press # instead — same thing, silently.
Text it what you ate
Just the words: "two eggs and toast". No app, no searching a database, no photographing your plate. It answers with where you are for the day.
What the rest of the week looks like
Not much, deliberately. Jai texts you at most once a day and three times a week, and it goes quiet on its own if you don't answer — it will never chase you twice about the same thing. On the day you chose, you get a short review of the week with one thing to aim at for the next one.
Everything else waits until you ask. Features turn up one at a time, when they'd actually be useful, and if you say no thanks you won't be asked again.
When Jai gets it wrong
This is the part worth reading twice. Jai mishears things, especially in a loud gym, and every mistake has a one-word fix.
- It logged the wrong food. Text no, one egg — the bit after "no" replaces what it logged.
- It got the numbers wrong. Tell it the real ones: no, 200 calories and 20 grams of protein. Your numbers always win — Jai won't look anything up or scale anything when you've told it.
- You eat the same thing every day. Tell it once: add shake: 160 calories, 30 grams protein. After that shake is all you need to type, forever.
- It logged something twice. undo.
- It mishears you mid-set. Say it again, or use the keypad. It will ask rather than guess when it isn't sure — one short question, never a silent invention.
- Something hurts. Say so. Jai stops the session, and it will never argue with you about pain.
Two things worth knowing
The phone call is the reliable path. You can train from the browser or the Android app, and most people do — but a browser can't hold a session with the screen off and the phone in a pocket. If you want to forget the phone exists during a workout, call it.
Nothing is shared unless you share it. Your weight, your measurements, anything you tell Jai about your health — no trainer and no gym can see any of it, and there is no setting that opens it. Here is the full list of what Jai will never do.
