Make your profile support
the same story.
A profile written separately from your resume can drift into a second version of your story. Undersold builds both from one evidence bank: same proof, warmer voice.

Watch it happen
The About section, before and after proof.
The first line frames everything that follows. Here is an illustrative, fictional example of how the opening can change.
Passionate, results-driven engineer with a proven track record of delivering scalable solutions.
Twelve words, zero verifiable facts. The language is generic enough to fit many profiles and gives the reader nothing specific to verify.
A line you defended in the discovery interview: page loads cut from 8 seconds to 2 on a client's biggest revenue site, measured in Lighthouse.

Same fictional person, but now the first line carries specific evidence and every claim after it is backed by the matching resume example.
What this does for you
Built around the work you actually did.
Undersold does not invent a better version of your career. It finds the evidence already inside it and helps you use that evidence clearly.
Headline
Say who you are before the detail.
Your headline follows you into every search result, every comment, every connection request. Written separately from your resume it drifts into keyword soup. Ours is built from the same evidence: identity, domains, and a proof point only if a proven number exists.
- Role and level stated plainly, no 'seeking opportunities'
- Search language your experience section actually backs up
- A proof point in the headline only when you can defend it
About
An About section designed to earn the next line.
The opening lines carry the most visible context before 'see more'. We open with the strongest true thing you have, develop the same themes your resume summary promises, and end with what you want next. First person, real voice, zero invented facts.
- A hook line built from your best proven fact, not an adjective pile
- The same two or three themes as your resume, so both surfaces agree
- Written in a spoken register you can edit into your own voice
Experience
One story, told twice, never contradicting itself.
A profile may be compared with the resume, so contradictions create avoidable doubt. Every experience entry here is distilled from the same rewrite bullets, in a warmer register with identical facts. Same titles, same dates, same numbers.
- Role descriptions distilled from your proven resume bullets
- Skills ordered by relevance to the story, drawn from real experience
- Featured section suggestions when you have proof worth pinning
The difference
Profile writers polish. We reconcile.
| Dimension | Profile writers & AI tools | Undersold |
|---|---|---|
| The headline | Keyword soup, or 'Seeking opportunities' | Identity, domains, and a proof point only if a proven number exists |
| About section | An adjective pile in third person | A hook from your best proven fact, in the way you actually talk |
| Profile vs resume | Two documents slowly drifting apart | One evidence bank, zero daylight between them |
| Skills | Everything you have ever touched | Ordered by your story, backed by your experience section |
Fair questions
Why the profile matters more than you think.
The profile is not a second resume. It is another public surface that should agree with the resume.
Recruiters don't even read profiles.
Some recruiters consult LinkedIn during screening and others do not. Keeping the facts aligned avoids contradictions when they do. Alignment is the point.
My profile is fine. It's my resume that's weak.
They are built from the same evidence here, so fixing one fixes both. And if your profile really is the stronger one, the discovery will show you what it says that your resume forgot to.
I hate writing about myself in first person.
So does everyone, which is why most About sections are empty or written in corporate third person. We draft it from your banked evidence in your spoken voice, and you edit. Editing a true draft is easy; the blank box was what was hard.
Where this comes from
A method from real resume teardowns, not a prompt.
Undersold is an interview a career mentor has been running with real job seekers for years: score the resume honestly, refuse anything that cannot be defended, and pull the real wins out of the person sitting across from you. We turned that interview into software without softening its rules.
- Built from a repeatable resume-teardown and mentoring method, not scraped resume templates
- Nothing renders unless you said it and confirmed it; numbers you cannot defend never make the page
- The same evidence drives your resume, LinkedIn, and interview answers, so your story holds up in the room
- The score applies the same ten checks to every bullet and shows the reason behind each result
Start with what you have
Your proof already exists. Put it where they look first.
Your resume does not need to be polished. It only needs to be yours. The score, your automatic Baseline, and 1 evidence-backed rebuild are free.
