Your first personal assistant

In this step-by-step tutorial, you will create your first personal AI assistant with Latenode. By the end of the tutorial, you will have a simple yet complete AI assistant that can get natural-language tasks from the Telegram chat and helps you to handle your e-mails, tasks and meetings. Look at the final schema of the assistant at the image below.

The tutorial assumes that you already have an account and know some Latenode basics. If not, you should go through Getting started first.

It also assumes that you are using an online-version of Latenode. If you are using a standalone version, some interfaces, links and details may vary.

The major steps are:

  1. Add necessary nodes
  2. Configure the tools
  3. Decide on the environment
  4. Fine-tune the agent

Add necessary nodes

In this short first part, we'll just fill a new scenario with necessary nodes.

Let's create a new scenario and add the first node:

  1. Log in to Latenode and go to scenarios page.
  2. Press Create a new scenario and optionally set the scenario name at the left corner of the page. For example, let it be My First AI Assistant.

  3. Press Add a Node to Begin and choose AI Agent... from the list of available nodes. Then choose common AI Agent node.

    The node appears on the board and the node settings window pops up. Press the node name UNTITLED and rename to Stanley. For now leave other settings by default and close the window, we will back here later.

This AI Agent node is the brain of our assistant, who will manage the other nodes. We want our assistant to be able to read mails and create mail drafts, check and create events in Google Calendar, list and create tasks in the task tracker.

Now let's add tool nodes to manage:

  1. Press Add node in the bottom menu. Find and click Gmail... app. Use the search field to find it easy.
  2. Choose the Create Draft node.
  3. Repeat the process for the Find Email node.

  4. Add the following nodes in a similar way:

    • List Events and Create Event nodes from Google Calendar... app.
    • List uncompleted tasks and Create Task nodes from Todoist... app.
    • Create Chat Completion from AI: Perplexity... app. We will explain this point later.

  5. Connect the AI Agent node with every tool node. You should get a layout like in the image below.

First Layout

You can see that our tool nodes are marked with yellow triangles. It means that we should configure this nodes properly.

Configure the tools

Let's give OAuth tokens to our nodes to connect them with real systems — Todoist, Gmail and Calendar:

  1. Click a Todoist node and press Sign in. If you are not authorized in Todoist yet, system prompts you to sign in.
  2. Sing in if needed. You'll see that the Connection field contains an auth token.
  3. Press Save and close the window.
  4. Click another Todoist node and make sure that it has the same auth token appointed. You can manage your authorizations and rename them in Authorizations section in left menu.
  5. Repeat above steps for Gmail and Calendar nodes. It may require giving necessary permissions for Latenode. It is safe.

Now we need to give our nodes descriptive names, clear descriptions and specify fromAIAgent operator for some fields. It provides the AI Agent with reliable information about these nodes.

  1. Click Perplexity node and change its name on the top from Untitled to web-search. This is not a trivial step, as the AI agent uses the node name to understand its purpose.
  2. Tweak tool description like this: Perplexity is an AI-powered search engine delivering accurate, concise answers and context.
  3. Click the User prompt field, delete prefilled text, and choose the fromAIAgent operator in popup menu. Tweak the prompt like this: Your new question prompt.
  4. Press Save.

Config Perplexity

Now let's set up our Google calendar nodes:

  1. Click List events node and rename it as list_calendar_events.
  2. In the Calendar ID field choose your Google calendar.
  3. In the Tool description field insert the following text: Retrieves events from Google Calendar within the specified window.
  4. Choose your time zone in the Time Zone field.
  5. Toggle Show advanced settings and find Time Max and Time Min fields. This parameters define the time window we mentioned in tool description. Click Time Max and choose the fromAIAgent operator in popup menu. The operator is filled in automatically, but let's tweak the prompt like this: Must be an RFC3339 timestamp with mandatory time zone offset, for example: 2011-06-03T10:00:00+03:00. Repeat this for the Time Min field.
  6. Press Save.

Config Calendar

Configure the rest of nodes in a similar way. Corresponding fields are listed below.

  • Node Create Event:

    • Name: create_calendar_event
    • Calendar ID: your Google calendar.
    • Tool description: Creates a calendar event
    • Start Date: Format according to RFC3339: yyyy-mm-dd-Thh:mm:ss+03:00
    • End Date: Format according to RFC3339: yyyy-mm-dd-Thh:mm:ss+03:00
    • Summary: Title of event (by default).Replace default Summary with Title
    • Description: Description
