Set Up your AI Agent

Creating an AI Agent is like building your own smart digital assistant — one that performs a specific task exactly the way you want it to.
In this section, we’ll walk through the full process together, using a real-life example to show how it works.
Let’s build an AI Agent called “Essay Evaluator” — an assistant that can grade essays using rubrics and generate helpful feedback.
From the left-hand menu, click on AI Agents.
This takes you to the main screen where you can:
Browse and reuse ready-made agents
See agents you’ve already created
Start building your own agent
At the top of the screen, you’ll see this question:
“What do you want to build?”
Here, you’ll describe in plain language what you want your AI Agent to do. For example:
“I want to build an AI Agent that can read and evaluate student essays based on five criteria: content relevance, structure, grammar, critical thinking, and clarity. It should give a total score and individual feedback on each section.”
Once you enter this, you have two options:
Click Generate to let the platform automatically fill in all the fields for you.
The system will generate:
Agent name
Agent description
Welcome message
Tool logic prompt
You can review and edit everything before saving.
Click Build Manually if you want full control.
You’ll manually enter each setup field step-by-step:
Agent Name
A simple name like “Essay Evaluator” or “Grammar Coach”
Agent Description
A short sentence explaining what the agent does. Example: “An assistant that evaluates essays based on specific scoring criteria and gives helpful feedback.”
Welcome Message
This is the first message users will see. Example: “Hello and welcome! I’m the Essay Evaluator. 📝🎓 Please upload or paste your essay to get started.”
Tool Icon
Optional image or icon to personalize the agent’s look
✅ Tip: If you prefer customization and already have a clear idea, use the Build Manually option. If you need help getting started, Generate is a great head start.
Next, you’ll write a Tool Prompt — a detailed instruction that tells your AI Agent exactly what it should do.
“Essay Evaluator greets the user and asks them to upload or paste their essay. It then evaluates the essay based on five criteria: (1) Content Relevance, (2) Structure & Organization, (3) Grammar & Language, (4) Originality & Critical Thinking, and (5) Clarity. For each area, the agent assigns a score, provides a brief comment, and then shares a total score out of 100 along with a summary paragraph of feedback.”
✅ Tip: Be as clear and specific as possible — the more structured your instructions, the better your agent will perform.
Once you've defined what your AI Agent should do, you have the option to fine-tune how it behaves by adjusting advanced AI settings. These controls help you shape the style, depth, and creativity of your agent’s responses.
Here are the settings you’ll see:
This lets you choose the type of AI model that powers your Agent. Think of it as choosing the engine for your car — it affects how powerful and capable your Agent is.
You have two options:
If you’ve already created an AI Avatar on the platform (like a tutor, coach, or expert), you can select that avatar as the core engine. This means your Agent will inherit the voice, tone, style, and personality from your Avatar.
Best for when you want your AI Agent to reflect your existing assistant’s approach.
Your Agent will still perform the specific task you assign, but with the Avatar’s voice and behavior.
If you don’t want to use an Avatar, you can choose a general-purpose AI model:
GPT-3.5: Efficient and basic, suitable for simple tasks.
GPT-4: Advanced and more accurate for reasoning and detailed logic.
GPT-4o: Optimized version of GPT-4, faster and better at multi-step thinking and language nuance.
✅ Recommendation: Use GPT-4o if you want the best mix of performance and depth — especially for evaluation, analysis, or tutoring use cases.
This setting controls how diverse or focused the responses are.
1.0 (default): Balanced — gives natural, varied answers.
Lower (e.g., 0.7): More focused and predictable.
Higher (e.g., 1.2): More creative and varied (not recommended for strict tasks like grading or scoring).
✅ Tip: Leave it at 1.0 unless you want to narrow or broaden how many different ways the agent can respond.
This controls how creative vs. conservative your AI Agent is in its answers.
Low (e.g., 0.2–0.4): Less creative, more precise (great for structured tasks like grading or math).
Medium (0.5–0.7): Balanced — thoughtful and conversational (best for feedback or evaluations).
High (0.8–1.0): Very creative — ideal for brainstorming or open-ended writing.
✅ Example: For the Essay Evaluator, a setting of 0.6 is a good balance — it will follow instructions but still write natural-sounding feedback.
Your AI Agent can be enhanced with optional capabilities. These are add-ons that expand what your agent is able to handle.
You’ll see three options:
Allows your agent to search the web in real-time to fetch up-to-date information.
Use it for:
Research-based agents
Product comparison tools
Current event-related tasks
⚠️ Not needed for tasks like essay grading, math solving, or document-based feedback.
Activates a special math engine so your AI Agent can:
Do advanced calculations
Solve equations step-by-step
Show math solutions clearly
✅ Best for: Math tutors, test prep agents (SAT, GRE, etc.), homework checkers.
Allows your Agent to refer to PDFs or documents that you upload. This makes your Agent more accurate, detailed, and personalized to your specific way of working.
We’ll explore this further in Step 6 (below), but here’s a quick preview:
✅ Great for: Agents that grade, explain, coach, review, or answer in-depth questions using your material.
A Knowledge Base is a collection of learning materials (usually PDFs) that your Agent can study and refer to when answering questions.
This makes your Agent more powerful and context-aware. It's like giving your assistant a binder full of instructions, examples, and guidelines.
Use it if:
You want your Agent to follow a specific grading rubric
You have teaching guides, SOPs, FAQs, or resource manuals
You want the Agent to speak in your voice or follow your method
If you checked the Knowledge Base box in Step 5, you’ll now see the following options:
Option 1: Select Existing Knowledge Base
If you’ve already uploaded materials before, simply choose from the dropdown list.
Option 2: Create a New Knowledge Base
Click “Create New Knowledge Base” and fill out the form:
Name
Give it a clear title, like “Essay Evaluation Knowledge Base”
Description
Describe what the documents contain. For example: “Includes essay rubrics, sample scoring guides, and evaluator instructions.”
Tags
Add searchable keywords like: essay, rubric, SAT, IELTS
Upload Files
Upload PDFs (drag and drop or browse from your device). Max 10 files, total size up to 50 MB.
Examples of Uploadable Documents (according to our example):
essay-rubric.pdf
grading-criteria-handbook.pdf
sample-high-score-essay.pdf
Once you hit Create, your Knowledge Base will be attached to your Agent and ready to use.
Now your AI Agent knows your way of doing things.
We are adding an example of knowledge base creation for our essay evaluator tool.
Once added, your AI Agent will be able to:
Reference these documents while answering questions
Stay consistent with your standards and formats
Explain its logic using the material you provided
Step 1
Opened the AI Agents dashboard
Step 2
Chose whether to use “Generate with AI” or “Build Manually”
Step 3
Entered core details: name, description, welcome message, and image
Step 4
Selected the AI engine — either an existing AI Avatar or a predefined model
Step 5
Enabled capabilities like internet access, math solving, or knowledge base
Step 6
Attached or created a Knowledge Base with your own training materials
Step 7
Saved and launched your Agent for live use
Your AI Agent is now ready — fully customized, purpose-built, and powered by your instructions and resources.
