Endless Love Letters

This is the source code for the site at https://endless-love-letters.com

Since 2019, I have written my wife Abby a love letter every day, for a total of 1458 captured at the time of the Google Takeout export.

These scripts take an .mbox file with a bunch of love letter emails, parse them out, feed them to the OpenAI GPT 3.5 finetuning API to finetune a model, then generate new love letters.

The web interface includes both v1 (static love letter list generated with some pre-GPT charNN-like solution whose name has been lost) and v2 (love letters generated on the fly with ChatGPT).

Populating the SECRETS file

Look at SECRETS.example for the tokens which should go into SECRETS, which is a JSON file. Neither the site nor the command line tools will function without the SECRETS being set.

Generating a love letter offline

Offline meaning without the web app, this still contacts the OpenAI API.

Just run:

python generate.py

Note that the prompts and model id are hardcoded into the script.

Generating the database

In MySQL, run:

CREATE DATABASE endless_love_leeters;

Then load the schema:

mysql -u <user> -p endless_love_letters < schema.sql

Running the web app locally

FLASK_DEBUG=1 FLASK_APP=app pipenv run flask run

Deploying to fly,io

Install the Fly.io command line tool, flyctl
