Memento (working title)

Memento is a Python app that records everything you do on your computer and lets you go back in time, search, and chat with a LLM (Large Language Model) to find back information about what you did.

How it works:

• The app takes a screenshot every 2 seconds
• It compiles the screenshots into h264 video segments for storage efficiency
• It uses OCR to extract text from the images
• It indexes the text in a sqlite3 database and a vectordb
• It uses FTS5 to search the text
• It uses a LLM (GPT through OpenAI's API) to chat with the timeline

This project is heavily inspired by rewind.ai

Installation

This project was tested on Ubuntu 22.04.

$ pip install -e .

You also need to install tesseract-ocr on your system. To install latest version (tesseract 5.x.x):

$ sudo apt update
$ sudo add-apt-repository ppa:alex-p/tesseract-ocr-devel
$ sudo apt install tesseract-ocr

Then install the language packs you need, for example:

$ sudo apt install tesseract-ocr-eng
$ sudo apt install tesseract-ocr-fra

You also need to set an environment variable : (This is the path on my system, it may be different on yours)

export TESSDATA_PREFIX=/usr/share/tesseract-ocr/5/tessdata/

Usage

Background process

Run in a terminal

$ memento-bg

Show the timeline:

Then use ctrl+f to search.

If you want to chat with the timeline through a llm, you need an openai api key in your env as OPENAI_API_KEY. Then use ctrl+t to open the chatbox.
