Screenshot the conversation. Caliber gives you three replies you could send, each with the reasoning behind it.
Your words, sharpened. Not replaced.
You decide what to send. Caliber never sends anything for you.
She closed the gap completely. Named the place, the day, and the time.
yeah, thursday works. see you there
What this avoidsDon't say 'I'd love that' or 'sounds amazing.' She gave you a short, confident ask and a formal response makes you look like you've been waiting by the phone.
Don't over-confirm. 'Yes! Thursday at 7 works great, I'm really looking forward to it!' is the texting equivalent of showing up 20 minutes early and ringing the doorbell twice.
only if the octopus is better
Caliber output from a live run on an example conversation. The conversation is made up. The read is not.
Momentum: will it keep going. Trajectory: is it moving toward meeting up.
Screenshot a conversation. See what's working and what isn't. Learn the principle behind it, then move on.
Take a screenshot of any text conversation. Caliber reads the text on your iPhone. With your consent, that text goes to a third-party AI service to write your coaching.
Get your read: their interest, momentum and trajectory, three coached replies with the why behind each, and what to avoid.
Each analysis leaves a principle behind, in plain words: Great banter earns the ask. Stop banking it.
They collect in your Playbook, and Caliber brings the relevant ones back into later coaching.
Screenshot their profile and get three opener directions, each built on something that's actually there.
Take a screenshot of their profile. With your consent, Caliber sends those screenshots to a third-party AI service to write your openers.
Three opener directions, each anchored to something specific in their profile, so your first message shows you actually read it.
An opener tied to something they chose to share gives them an easy way to answer.
Same coaching, a different starting point. Profile Review works the same way on your own profile: a first-impression read, what's working, and the one change to make first.
A reply generator hands you a line. Caliber shows you the move. Every suggestion comes with the reasoning behind it, so you can judge it for yourself and learn what works.
They asked what the cumin did. You answered in two paragraphs. They said “ha,” then “sometimes.” Caliber read both moments, and the second read caught what a friend skimming the thread would miss.
The joke was the door. You tried to walk through it carrying furniture.
Same person. Same night. Two paragraphs later.
Caliber output from two live runs on an example conversation, before and after the paragraphs.
The coaching draws on published studies of conversation, interest and learning, not forum threads. The research section below shows which ones, and who was studied.
Three different approaches: clear and direct, warm and playful, genuine and curious. Each comes with its reasoning, so you learn the move, not just the line.
Two scores track different signals: will the conversation keep going (momentum) and is it moving toward meeting up (trajectory). Great banter with no plan scores high on one and low on the other.
Press and hold a reply to refine it: shorter, more direct, more relaxed, with a question added, or in your own words.
A read on their interest, based on what they actually wrote. Caliber reads only what's on the screen, so treat it as a second opinion, not a verdict.
Your analyses leave principles behind. They collect in your Playbook, and Caliber brings the relevant ones back into later coaching.
Tap “I sent this” on the reply you used, then tell Caliber how it went: they replied, made plans, still talking, or faded out. The Playbook marks which principles led somewhere.
After five analyses in one conversation, a Deep Dive reads its whole history and pulls out the lessons.
You track your lifts, your sleep, your spend. Caliber gives your conversations the same rigor: real signals, scored analysis, no guesswork.
You screenshot every conversation and send it to the group chat. You draft three versions of a reply and send none. Caliber gives you a second opinion and the reasoning behind it.
It's been a while since you put yourself out there, and you feel rusty. Caliber helps you find your footing again, one conversation at a time.
You don't want a pep talk. You want signal. Caliber gives you scored reads, trend direction, and which principles actually led somewhere.
Skip the emergency session. One screenshot, three replies and the why.
Four published studies shaped the coaching. Each one below says who was studied, because a study of seventh graders is not a study of you.
In text chats between strangers, people who asked more questions, especially follow-up questions, were better liked by the people they talked with.

In hypothetical ratings, people said a potential partner's negative traits would lower their interest more than positive traits would raise it.

College students whose use of small words like pronouns and articles was more alike in a four-minute first meeting more often both wanted to meet again.

Seventh graders scored 74% versus 42% on a surprise math test a month later when two problem types were mixed in practice rather than grouped.
Rohrer, Dedrick & Stershic, 2015 · Journal of Educational Psychology · N = 126, d = 0.79 · doi:10.1037/edu0000001
These studies shaped how Caliber coaches. They are published research on people, not tests of Caliber.
