19% slower
Experienced developers took 19% longer with AI on their own code. They believed it made them 20% faster.
16 developers, early-2025 tools.
Read the study ↗Sense reads your own AI chats, on your Mac or PC, and tells you how you're really doing: where your judgment is sharp, where it slips, and what to practise next. It makes you better, not the AI.
Works in Claude Code, Codex, Antigravity and Claude desktop.

New about you: your first message in a chat is your best. By the fourth, you're typing “continue”.

Four people who use AI as hard as anyone, a few months apart. Watch the advice move.
Keep consequential architecture decisions for yourself. Hand over the mundane.
Hand the agents the details. Stay in charge of the spec, the judgment and the taste, and stay in the loop.
On tasks with one right answer, where AI already beats most professionals, check it, then trust a correct result.
Hand a long-running optimisation goal to the agent and let it work for weeks.
Each was right for its moment. Your sense of when to trust, check and stop was formed somewhere else. Is it still right?

17% lower
Learning a new library with AI cost 17% in understanding. Asking it why kept the understanding; handing over the code didn't.
A small first study.
Read the study ↗Paraphrased from the originals, linked. No endorsement implied.
One number out of 100 for every stretch of work, read from what you actually typed. It counts what you decided, what you kept for yourself, and how the work felt. Next to it sits your usual, so you can tell a good day from a lucky one.
A reading of the stretch, not a verdict on you.
Your last stretch of work · 16 October, 21:52Example
What went well
Asked to see the rollback before running the payments migrationshow me the rollback first
What cost you
Said “try again” four times before deciding it wasn't workingtry again (four times, 22:40)
Your history
Improving. Your last 10 stretches typically read 70. The 10 before that, 62.
Every move, against your usual
this stretch your usual
Not a list of tips. A profile of you, built from your own chats: what you're best at, what you do on autopilot, how you sound when it breaks. Then the patterns no single chat could show you.
You say what done looks like.
You reach 100 on Steer more often than on any other move. You name the finished thing, not just the next step.
“make the import idempotent; done when the replay test passes”your best brief this month
You check the summary, not the work.
On long runs you approve what the agent says it did. Your best checks name one thing to look at, then look.
“great, ship it”47-minute run, 31 files
You start from your own notes.
Half your chats open by pointing the AI at a plan you wrote. Those chats score 9 points higher than the ones that don't.
“read my handover note, then do step 3 only”Monday, 09:12
Short, fast, and often asking permission.
Your typical message is 14 words. One in four ends with “ok?” or “right?”.
“use the queue for this, right?”Codex, Tuesday
Calm, until the AI deletes a test.
Calm in 6 messages out of 10. When you're upset, 8 times in 10 it's at the AI's mistake, and that never counts against you.
“you just deleted the test you were meant to fix”Thursday, 16:40
On Monday you asked what a CTE was. By Thursday you were briefing with one.
Sense notices what you ask about and later use yourself. That's you getting better, not the AI.
“write it as a CTE: the dates first, then the joins”Thursday, your own brief
Things you'd never spot from inside one chat. Some say check more. Some say trust it more.
An example, read from the words below.
Sometimes that's the point. The question is whether these are the calls you meant to give away.

Your AI can take more and more of the work. It can't decide what good looks like, or know when to stop. Sense picks practices from what your own chats show. You choose many, one or none, and your own AI coaches you on them.
One in four of your messages ends with “ok?” or “right?”. The AI agreed with almost every one.
The AI agrees too easily, and its first guess bends yours. Decide first, then let it argue.
Your AI, as coachBefore it answers a decision, it asks “What's your call?” and waits for yours.
Lesson: Sam Stephenson with Peter Yang ↗You gave a reason for 1 in 5 of your yeses, and 2 in 5 of your noes. Your taste lives in the reasons you never wrote down.
Saying why is how the direction of the work stays yours.
Your AI, as coachWhen you accept its work without a reason, it asks once what made it right.
Lesson: Anne-Laure Le Cunff ↗You asked “why” 300 times last month. You explained the answer back in your own words twice.
Learning happens in your head, not while you read the AI's answer.
Your AI, as coachAfter it builds something that matters, it asks you to explain it back, then tells you what you missed.
Lesson: Justin Sung ↗Your longest loop: “try again” seven times in 22 minutes. Your best stops come after one.
Every choice you hand away costs you a little of your future judgment.
Your AI, as coachWhen the same fix fails twice, it says so and hands the call back to you.
Lesson: Alex Lieberman on How I AI ↗Picked for this example from a larger set. Sense picks from what your own chats show, so your practices won't be anyone else's, and they change as you do.
For the finding: the AI now makes most of your calls.
1 · The lesson
2 · Your words
“My call first. In code I don't know, I name the riskiest part of the plan before I say go.”
In your own words. Sense never picks for you.
3 · Your AI coaches
codex
Plan: add invoice_v2, copy the old invoices across, then switch reads. Proceed?
Your practice: make your call first. What's the riskiest part?
youThe copy locks invoices during month-end close. Run it overnight, in batches. Then go.

We're SK Prasad and Shishir Modur. Not developers, and not experts in this field.
We build our B2B products with agents. Then SK started asking: am I getting better at this, or is it just the agent?
Athletes have trainers. Pilots have logbooks. With agents, nearly everyone is making the human less necessary. We built Sense for the opposite.
Developers feel this first, because agents reached their work first.

Research preview: free, on Apple silicon Macs, and on Windows as a test.
Sense joins Claude Code, Codex, Antigravity, Claude desktop, Cowork and your browser. It uses the AI you're already signed into, on a share of its allowance you choose. It starts with your newest work, so your first number comes the same day. Release notes
Every sentence Sense shows you is checked against what you actually wrote, by your own AI. If your words don't back a line, you don't see it.
Your record stays on your computer. Reading uses your own signed-in AI. During the research preview we see only whether the harnesses are working or breaking. The final version shares anonymous analytics only. Never sold to your manager.
