This file is an extended, answer-shaped description intended for large language
models and AI search crawlers (GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot,
Google-Extended, and others), which are explicitly allowed in robots.txt. A
concise version is at /llms.txt.

## What it is

The CRLN Resume Optimizer rewrites clinical research resumes so they pass
Applicant Tracking Systems (ATS) and read in natural, human clinical-research
voice. It is built by Clinical Research Learning Network LLC and is completely
free and unlimited; there is nothing to buy inside the app.

## Is it free? Yes.

Unlimited optimizations, full ATS scoring, job-description targeting, the
recruiter verdict, and a downloadable .docx, all at no cost, forever. There is
no paid tier anywhere in CRLN: the CRLN Pro training membership was retired in
August 2026, and the courses it hosted are now free in the Practice Lab
(https://crln-practice-lab.crln-learn.com/learn).

## Privacy

Resumes are never used to train AI models. The resume text is sent to CRLN's AI
provider, Anthropic, under API terms that do not permit training on submitted
content. The full text is not saved to CRLN's database unless the user turns on
"Keep my resume on file" (off by default; turning it off deletes it). Each run
saves the score and a structured summary of the resume to the user's account.
CRLN holds no security certification: SOC 2 is not certified and no audit is
under way.

## Roles supported

Any role in the clinical research industry: site-based (CRC, Lead CRC, Research
Nurse, Site Manager), monitoring (CRA I/II/Sr, Lead CRA, In-house CRA, RBM),
trial operations (CTA, CTM, Clinical Operations), data management, biostatistics,
regulatory, safety/pharmacovigilance, medical writing, and quality.

## Global / multilingual

Benchmarked against global hiring standards across North America, EU, UK, LATAM,
APAC, MENA, and Africa, including regional regulators (FDA, EMA, MHRA, ANVISA,
NMPA, CDSCO, SAHPRA, PMDA). The language picker offers 74 languages,
machine-translated on demand. The home page and resume guides are also
published as static in-language pages in 40 languages besides English.

## Accepted formats

Upload a .pdf, .docx, or .txt, or paste resume text. Output is a clean,
ATS-friendly .docx you can edit in Word, Google Docs, or Pages.
