formalyzer 0.0.2

Analyze PDF and web forms and fill in the forms

formalyzer

Description:

Formalyzer will scrape the text from the PDF recc letter, and for each URL in url_list, it will:

• launch a browser tab for that url
• fill in the form using what the LLM has gleaned from the recc letter
• attach the PDF via the form’s upload/attachment button

…and do no more.

The user will need to review the page and press the Submit button manually.

Requirements:

• Either ollama installed locally or ANTHROPIC_API_KEY environment variable set
• beautifulsoup4, playwright, claudette, lisette, pypdf, fastcore

Usage

On MacOS, startup the Chrome browser looking to port 9222 by executing this command in the terminal:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug

Then you can run this command:

formalyzer --debug <recc_info.txt> <recc_letter.pdf> <url_list.txt>

where recc_info.txt contains information about the recommender, their name, their title, their address, phone number and email. urls_list.txt is a file containing one URL per line.

Installation

Install latest from the GitHub repository:

$ pip install git+https://github.com/drscotthawley/formalyzer.git

or from pypi:

$ pip install formalyzer

After installing, users need to run playwright install chromium to download the browser binaries.

Demo

On MacOS, run these commands in Terminal:

1. /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222 --user-data-dir=/tmp/chrome-debug &
2. cd example
3. python -m http.server 8000 &
4. export ANTHROPIC_API_KEY="__your_API_key_goes_here__"
5. formalyzer --debug recc_info.txt sample_letter.pdf sample_urls.txt

Local LLM Execution

For FERPA compliance, running a local model is preferable so that student data is not broadcast elsewhere. I recommend using ollama and starting with something medium-small like qwen2.5:14b (9 GB). Start up ollama:

ollama serve & 
ollama pull qwen2.5:14b 

Then you can use the --model CLI flag, e.g. 

formalyzer --debug --model 'ollama/qwen2.5:14b' recc_info.txt sample_letter.pdf sample_urls.txt

The quality of the form-filling will vary depending on the quality and size of the model you get. Smaller models like mistral (4 GB) may hallucinate many of the form field IDs, resulting in a mostly-blank form in the end. For a huge (41 GB) model, try ollama/qwen2:72b.

TODO:

• Test with a less-than-superlative recc letter – to make sure it’s not just always selecting the top rating(s).
