ChatGPT - Offline alternatives

A few months ago, ChatGPT gained a huge following and drew attention to new AI tools. However, interest in these AI tools has since waned.

This article aims to highlight recent advances in Natural Language Processing (NLP) and Large Language Modelling (LLM), with a particular focus on offline tools similar to ChatGPT.

  1. Offline ChatGPT alternatives
  2. Currently there are several NLP (Natural Language Processing) tools similar to ChatGPT - Bing chat, Gemini & Bard, Llama 2, and EARNIE Bot - most of which are online. Listed below are some offline ChatGPT-like language processing tools.

    Keep in mind that new tools and updates are released on a weekly basis, so the items listed here may be outdated, replaced or modified in a short period of time. Nevertheless, it is useful to understand what is out there.



    • Data security
    • Intergration with the local environment
    • Easier Cusomisation of language models
    • Free from constraints & biases
    • Mostly open source
    • Optional cost-free operation
    • Limited factual database
    • May lack creativity & accuracy
    • Requires capable CPU/GPU, memory & space
    • Should be updated manually
    • Slower response
