When to create your own assistant

\n

There are a few scenarios where you will need to create your own assistant to complete the task you need help with:

\n
    \n
  1. When you want an assistant's output to be a formatted file (e.g. a word document with a standardised format). You will need to create a template and create an assistant for each template, if you have more than one
    2. \n
  2. If you have specific style or other preferences that you want the assistant to remember
    3. \n
  3. If you want to add a knowledge base of assistant files - either manually or via integration
    4. \n
  4. If you want to use the memory feature - where all conversations with an assistant are remembered and can be accessed to answer a new query.
    5. \n
  5. If you want to disable specific tools in an assistant (e.g. web search, code interpreter or image generation)

Assistant creation

\n
    \n
  1. Navigate to the Theta Assist home page and click “Create Assistant”.
    2. \n
  2. Give your assistant a useful name (to help you and/or others find it later).
    3. \n
  3. Add a description. This appears on the assistant's card on the home page.
    4. \n
  4. Add placeholder text to guide users on how to interact with the assistant, eg \"Upload a document and ask me to generate a glossary from it\".
    5. \n
  5. Decide if you want to share your assistant so others can use it. We always recommend a few rounds of testing before you share.
    6. \n
  6. Adapt the default Instructions / System Prompt to suit your desired task, or replace them entirely. See guidance on this below.
    7. \n
  7. Click Save. Your new assistant is now ready to use \uD83D\uDE0A
