✨ Features

• Scrapes LinkedIn job title, company, location, and full job description with Playwright.
• Reuses a persistent browser profile so you can keep a logged-in LinkedIn session.
• Prompts for a Gemini API key and a plain-text base CV, then stores them locally for later runs.
• Includes a built-in cvalchemix login command to open LinkedIn and persist an authenticated browser session.
• Rewrites the CV into a structured CVData schema using Google Gemini.
• Renders the final CV through a Jinja2 LaTeX template and compiles it to PDF with tectonic.
• Saves the intermediate .tex file alongside the PDF so you can inspect the generated LaTeX.
• Includes show-config and delete commands for inspection and cleanup.

🎯 Use Cases

• A job seeker can paste a LinkedIn posting and generate a tailored CV PDF that mirrors the role's keywords and structure.
• A candidate applying to several roles can reuse the same base CV and produce a separate PDF for each company and posting.
• A developer can automate a job-application workflow by combining the scraper, Gemini rewrite step, and PDF renderer in one CLI.
• Someone keeping a persistent LinkedIn session can avoid repeated logins when scraping job pages over time.
• A career coach or reviewer can inspect the generated .tex and final PDF to understand how the CV was reshaped for a role.

⚠️ Current Limitations

These are known limitations in the current version. They will be addressed in future releases.

• LinkedIn URL format: Only the following URL pattern is currently supported:

  https://www.linkedin.com/jobs/collections/recommended/?currentJobId={currentJobId}
  

  Other LinkedIn URL shapes such as /jobs/view/ and search-result pages are not yet supported.

• AI Provider: Currently only Google Gemini is supported as the AI provider.

• External renderer: PDF generation depends on a local tectonic binary being available on PATH.

• Scraping fragility: The scraper relies on LinkedIn CSS selectors, so LinkedIn DOM changes can break extraction.

• Template scope: Only one bundled LaTeX template, classic.tex.j2, is shipped right now.

• No built-in fit score: The repository contains structured analysis models, but there is no user-facing command that emits a standalone job-match score or analysis report yet.

🔩 Prerequisites

• Python >= 3.10
• A Google Gemini API key
• tectonic installed and available on your PATH

Playwright and its browsers are installed automatically as part of the Python dependencies — no manual step needed.

📦 Installation

Option 1 — pip

pip install cvalchemix

Option 2 — pipx (recommended for CLI tools)

pipx install cvalchemix

Option 3 — One-command install (macOS/Linux)

curl -fsSL https://raw.githubusercontent.com/kayesFerdous/CVAlchemix/main/install.sh | bash

If you don't have curl:

wget -qO- https://raw.githubusercontent.com/kayesFerdous/CVAlchemix/main/install.sh | bash

Option 4 — Windows (PowerShell)

irm https://raw.githubusercontent.com/kayesFerdous/CVAlchemix/main/install.ps1 | iex

The installer scripts prefer pipx and fall back to pip --user when needed. You can override the install source with the CVALCHEMIX_INSTALL_TARGET environment variable.

✅ Verify Installation

cvalchemix --help

🚀 Quick Start

1. Configure the app with your Gemini key and a plain-text base CV.

cvalchemix configure

2. Optional but recommended — open a persistent LinkedIn session once so the scraper can reuse it.

cvalchemix login

3. Generate a tailored CV from a LinkedIn job URL.

cvalchemix generate "https://www.linkedin.com/jobs/collections/recommended/?currentJobId=1234567890" -o ./output

The CLI writes the final PDF to ./output/cv/<company>_<timestamp>/cv.pdf and saves the intermediate LaTeX source as cv.tex in the same directory.

📖 Usage

Command	What it does	Example
cvalchemix configure	Prompts for a Gemini API key and the path to your base CV text file, then saves them in the local config file.	cvalchemix configure
cvalchemix login	Opens LinkedIn in a persistent Playwright browser profile and stores login readiness for later generate runs.	cvalchemix login
cvalchemix show-config	Displays the saved configuration and masks the stored API key.	cvalchemix show-config
cvalchemix generate <job-url>	Scrapes a LinkedIn job post, rewrites your CV with Gemini, and renders a PDF. Use -o or --output to set the destination directory.	cvalchemix generate "https://www.linkedin.com/jobs/collections/recommended/?currentJobId=1234567890" -o ./output
cvalchemix delete	Removes local CVAlchemix data and uninstalls the package by default. Use --data-only to keep the CLI installed, and -y to skip confirmation.	cvalchemix delete -y

⚙️ Configuration

CVAlchemix uses two layers of configuration:

• CLI config — run cvalchemix configure to save your gemini_api_key and base_cv_path into a local JSON config file under your platform user config directory.
• LinkedIn session — run cvalchemix login once to open LinkedIn and save linkedin_login_configured for generate preflight checks.
• A .env file in the working directory is also read if present.

Environment Variables

Variable	Default	Purpose
GOOGLE_API_KEY	empty	Gemini API key used by the settings layer.
DEFAULT_MODEL	gemini-2.5-flash-lite	Gemini model name used by the LLM wrapper.
PROFILE_DIR	managed app profile directory	Playwright browser profile location for persistent LinkedIn sessions.
OUTPUT_DIR	./output	Default output directory used by the settings layer.
BROWSER_HEADLESS	false	Launch Playwright in headless mode when set to true.
SCRAPE_TIMEOUT_MS	30000	Timeout in ms while waiting for LinkedIn page content to load.
MAX_RETRIES	3	Number of retries defined by the configuration layer.
LOG_LEVEL	INFO	Root logging level.

A .env.example file with starter values for all of the above is included in the repository.
