Original resume line2 / 10
Worked on the AI matching engine and improved performance.
“Improved” how? No before, no after, no way to measure it.The resume is a clue, not the whole story
You did the work.Your resume forgot the evidence.
Most tools polish the words already on your resume. Undersold finds the proof that never made it there, then turns it into a story you can defend in the room.
- No credit card
- You confirm every fact
- Nothing invented
UNDERSOLD ASKS

Why rewording falls short
The strongest part of your career is often the part you left out.
You remember the project. The recruiter only sees “helped,” “supported,” or “improved.” The missing detail is usually where the value lives: what you owned, what was at stake, what changed, and how anyone knew.
Better writing cannot rescue missing evidence. Better questions can.
The usual approachSame facts, shinier sentence
The Undersold approachFind the facts, then write
Follow one line through the product
From vague claim to defensible proof.
One example, end to end. Each step has a job. Nothing moves into your documents until you can stand behind it.
01
Diagnose the document
The reveal
Score first. Write later.
Every bullet is read against the same recruiter-facing checklist: ownership, specificity, stakes, outcomes, proof, and readability. The score diagnoses the resume, not your ability or worth.
- The exact weak phrase is quoted back
- The missing evidence is named
- The next best question is already waiting

Uncover what is missing
The interview
We ask the follow-up you would get in the room.
Start with two optional warm-up questions by typing or recording your answers. After the reveal, continue in the typed discovery chat or choose the guided voice interview. Each path stays on one accomplishment until the ownership and outcome are clear.
- Questions target your exact evidence gaps
- Side mentions can surface hidden wins
- “I do not know” is safer than a made-up claim
Evidence interview One target at a time
UNDERSOLD
When you say you improved the matching engine, what changed after your work?
Match accuracy went from about 61% to 93% after I rebuilt the ranking model.
FOLLOW-UP

- Supporting quotes remain visible
- Metrics keep their measurement source

The full story behind the line
Proof is not just a revenue number
Strong evidence looks different at every level.
The method is designed for experience ranging from class projects to long careers. We look for what was hard, what you owned, and what changed.
Early career exampleProof of ownership
BEFORE
Helped create an app for a class project.
Question that unlocks it
Which part was yours, and who actually used it?
AFTER
Built the scheduling flow for a four-person capstone app, coordinating user tests with 18 students and shipping all assigned features before demo day.
Leadership exampleProof of scale
BEFORE
Led a transformation initiative across the organization.
Question that unlocks it
What changed, across how many teams, and how was success judged?
AFTER
Led a new release process across seven product teams, cutting average approval time from 12 days to 4 while maintaining the existing audit pass rate.
Examples are illustrative. Undersold uses only the facts you provide and confirm.
The difference
Rewording tools stop where Undersold starts.

Fair questions
You should be skeptical.
Resume products make a lot of promises. These are the parts you should verify before trusting one with your career story.
Read our privacy details01I already ran my resume through ChatGPT. How is this different?+
A general writing tool can only reword what you give it. Undersold starts by diagnosing what the resume fails to prove, then asks focused questions to uncover the ownership, outcomes, stakes, and measurement sources that were never on the page.
02Will Undersold invent numbers or experience?+
No. A number must have a measurement source before it becomes defensible evidence. Unsupported claims are removed or left as clearly marked gaps for you to answer. You confirm, correct, or reject extracted facts before they enter your Career Evidence Bank.
03What happens to my resume and answers?+
Your resume and answers are processed to build your documents, including by the AI providers that power the service. Adding a scrubbed copy to our product-improvement set requires a separate unchecked box you choose yourself. We do not sell your data.
04Does this work if I do not have impressive numbers?+
Yes. Proof is bigger than revenue metrics. It can be ownership, difficulty, scale, speed, reach, trust, complexity, or a concrete before and after. The questions adapt to the experience you actually have.
05What can I do for free?+
The free path includes your line-by-line resume score, the diagnosis behind it, an automatic Baseline resume, a guided interview, and 1 evidence-backed rebuild. No credit card is required. When you want more, Starter is $29/month and Premium is $99/month.
The score is not a verdict on you.
