The same resume, four real postings. Watch Covra read each one and start writing. Every underline is a real decision, drawn from the linguistic, persuasion, and negotiation research Covra applies to every letter. Covra does this automatically, every time it detects a job posting.

Wording Psychology Numbers

We ran the test so you don't have to.

One identical resume, one live job posting, given to Covra and the four major chatbots. Every letter was checked, unedited, against published hiring research. Here's what came back.

Flagged problems per letter

Invented numbers, stock phrases, template leftovers, em dashes. Lower is better.

Factual integrity flags

Numbers found nowhere on the resume, achievements credited to the wrong project, details added from outside your inputs. Lower is better.

Letter length (words)

How it works

01

Sign in and upload your resume

Authenticate with Google and upload your resume once — as a PDF or Word document. Covra stores it securely, and you're ready to start applying.

02

Browse jobs as you normally would

Navigate to any job posting on LinkedIn, Glassdoor, ZipRecruiter, Greenhouse, SimplyHired, and more. Covra detects the role automatically and begins writing in the background — before you even open the popup.

03

Deep research. Tailored output.

Covra analyzes the role requirements, the company's mission, and its industry positioning — then cross-references that context against your experience to produce a letter that is specific, relevant, and indistinguishable from one written with hours of preparation.

04

Download and submit

Click the Covra icon and download a professionally formatted .docx — saved as Your Name - Company - Cover Letter.docx. Ready to submit immediately.

The Science Behind Covra

Built on peer-reviewed research
from the world's leading institutions.

Always being updated.

Covra's generation model is under continuous development. As peer-reviewed findings in behavioral psychology, hiring science, and decision research are published and replicated, our team evaluates them for integration into the generation prompt.
