Know exactly why your resume gets rejected.
Signal simulates what an ATS extracts, scores what recruiters actually look at, matches you against real job descriptions, and rewrites weak bullets without ever fabricating a fact. Every number comes with its evidence.
Free. No account needed. Your data is encrypted and auto-deleted.
ATS simulation, not guesswork
See exactly what an applicant tracking system is likely to extract from your resume — including the parsing failures that silently hide candidates: columns, tables, fonts, images, missing headings.
Evidence-based scores with receipts
Every score expands into the specific reasons behind it. Skills are only credited when evidenced in context — a keyword alone earns nothing. No black-box 'AI score'.
Truth-preserving rewrites
Bullet-by-bullet rewrites that never invent metrics, employers, or technologies. Missing numbers become [ADD METRIC] placeholders — you fill in the truth. A guardrail reverts any fabricated suggestion.
Seniority & company fit
Research-grounded ladders evaluate the behaviors you demonstrate — ownership, scope, mentoring, ambiguity — against your target level, plus public hiring signals for Amazon, Google, Stripe, NVIDIA and more.
Recruiter's 10-second test
A simulated first scan built on eye-tracking research: what stands out, what's unclear, and whether the recruiter keeps reading. Plus a hiring-manager assessment with interview likelihood.
Private by design
Resumes are encrypted at rest, auto-deleted after the retention period, and deletable in one click. Documents are treated as untrusted data — prompt-injection defenses run at every LLM boundary.
How it works
Upload your resume
PDF, DOCX, TXT, RTF, ODT — or an image for OCR. Text-layer, layout and font analysis runs automatically.
Define the target
Target role, company, seniority — and paste a job description for the full match engine. No JD? General health mode works too.
Get the diagnosis
Overall score with confidence, category breakdown, bullet-level analysis, ATS extraction preview, and a prioritized action plan.
Fix, then recalculate
Accept truthful rewrites, watch the before/after delta, and compare versions — the original is never overwritten.
What Signal does not claim
No proprietary ATS secrets. Vendor parser internals are not public — Signal models documented behavior and independent tests, and says so.
No objective truth. Scores are transparent heuristics with a confidence level and a trust score — the 6-second recruiter figure is triage, not a verdict.
No keyword-stuffing wins. Signal optimizes for accurately communicating your qualifications to machines and humans — evidence beats repetition.
No fabricated rewrites. Suggestions that introduce facts not in your resume are reverted by a deterministic guardrail.
