paperless-titles-from-ai

This is a project to generate meaningful titles for ingested paperless documents using AI. Sends the OCR text of the document to the OpenAI API and generates a title for the document. The title is then saved to the document's metadata.

Examples of Generated Titles

• taxreturntranscript2022
• aigclaims_check_20230313
• prosharesultrabloombergtax2023

Setup

Clone Repository

git clone https://github.com/sjafferali/paperless-titles-from-ai.git

Create .env file

cp -av paperless-titles-from-ai/.env.example paperless-titles-from-ai/.env
# Update .env file with the correct values

Update docker-compose.yml file

Update docker compose file with the correct path to the project directory.

services:
  # ...
  paperless-webserver:
    # ...
    volumes:
      - /path/to/paperless-titles-from-ai:/usr/src/paperless/scripts
      - /path/to/paperless-titles-from-ai/init:/custom-cont-init.d:ro
  environment:
    # ...
    PAPERLESS_POST_CONSUME_SCRIPT: /usr/src/paperless/scripts/app/main.py

The init folder (used to ensure open package is installed) must be owned by root.

Back-filling Titles on Existing Documents

To back-fill titles on existing documents, run the helper cli from the project directory:

docker run --rm -v ./app:/app python:3 /app/scripts/backfill.sh [args] [single|all]

Arguments

Option	Required	Default	Description
--paperlessurl [URL]	Yes	https://paperless.local:8080	Sets the URL of the paperless API endpoint.
--paperlesskey [KEY]	Yes		Sets the API key to use when authenticating to paperless.
--openaimodel [MODEL]	No	gpt-4-turbo	Sets the OpenAI model used to generate title. Full list of supported models available at models.
--openaibaseurl [API Endpoint]	No		Sets the OpenAI compatible endpoint to generate the title from.
--openaikey [KEY]	Yes		Sets the OpenAI key used to generate title.
--dry	No	False	Enables dry run which only prints out the changes that would be made.
--loglevel [LEVEL]	No	INFO	Loglevel sets the desired loglevel.

To run on all documents

docker run --rm -v ./app:/app python:3 /app/scripts/backfill.sh [args] all [filter_args]

Arguments

Option	Required	Default	Description
--exclude [ID]	No		Excludes the document ID specified from being updated. This argument may be specified multiple times.

To run on a single document

docker run --rm -v ./app:/app python:3 /app/scripts/backfill.sh [args] single (document_id)

Additional Notes

• The default OpenAI model used for generation is gpt-4-turbo. For a slightly less accurate title generation, but drastically reduced cost, use a GPT 3.5 model.
• The number of characters of the OCR text that is sent varies depending on the model being used. We try to send the maximum number the model supports to get the best generation we can.

Privacy Concerns

Although the OpenAI API privacy document states that data sent to the OpenAI API is not used for training, other OpenAI compatible API endpoints are also supported by this post-consume script, which allows you to use a locally hosted LLM to generate titles.
