WEBVTT 00:00.800 --> 00:01.440 Welcome. 00:01.600 --> 00:10.120 In this episode, we are going to build our very first agent and it's going to be something super practical. 00:10.440 --> 00:12.040 It will send emails for us. 00:13.040 --> 00:18.800 So this is probably one of the easiest agents you can build, but also one of the most useful. 00:19.440 --> 00:26.200 You will see how quickly it all comes together, and by the end of this tutorial, you will have a fully 00:26.200 --> 00:31.760 working setup that can understand your instructions and send emails automatically. 00:32.520 --> 00:41.520 So we will communicate with our agent via built in open chat and instruct it to send emails for us. 00:43.040 --> 00:46.480 And our agent is going to call tools. 00:46.480 --> 00:49.040 So Gmail Tool and Contacts tool. 00:50.040 --> 00:57.920 So it will retrieve the email address from the Google sheet I've prepared, and then craft an email 00:58.280 --> 01:00.240 and send it to that email address. 01:00.480 --> 01:07.800 We use a simple memory so it will remember the history of our conversation from our open chat, and 01:07.800 --> 01:10.880 we can specify how many messages we want it to remember. 01:12.320 --> 01:18.240 And we will trigger our an agent by this chat message. 01:18.920 --> 01:27.240 But you can easily connect third party apps like telegram, slack, WhatsApp, and you can find how 01:27.240 --> 01:32.880 to set up credentials and connect these nodes in the How to Setup credentials section. 01:33.880 --> 01:39.840 So you can either follow me step by step, or just copy the whole workflow and tweak it to your needs. 01:40.240 --> 01:47.920 And it's totally up to you, but I strongly recommend to learn with me along the way so we fully understand 01:48.240 --> 01:56.240 how it works and how you can build on top of that, and also how to add more tools to your agent. 01:57.000 --> 02:01.470 Alright, so let's start building and Create our agent from scratch. 02:02.510 --> 02:03.990 So let's create the workflow. 02:06.670 --> 02:11.030 First I'm going to add a chat trigger node as a trigger. 02:11.030 --> 02:13.510 So that will activate our agent. 02:16.710 --> 02:18.350 So let's search for chat. 02:20.950 --> 02:22.150 And select this one. 02:24.630 --> 02:25.870 Now let's close it for now. 02:28.390 --> 02:29.830 Now let's add our agent. 02:30.870 --> 02:32.270 So search for agent. 02:34.830 --> 02:35.870 Press on this one. 02:37.630 --> 02:40.470 So this is where we define the brain of the operation. 02:40.950 --> 02:47.670 So now to make the agent actually understand us I'm going to connect chat model. 02:51.950 --> 02:55.990 So we are going to use OpenAI GPT for all model. 02:56.430 --> 03:06.830 But you can choose your favorite large language model such as cloud, Gemini, grok, Mistral and you 03:06.830 --> 03:09.990 can connect to any LLM via operator. 03:10.750 --> 03:17.750 And I'm going to explain how to use operator in the setup credentials section. 03:18.990 --> 03:26.790 So if you are looking for LLM that has a dedicated node in N810, you can use operator. 03:27.830 --> 03:28.190 All right. 03:28.190 --> 03:29.790 So let's use OpenAI chat model. 03:32.670 --> 03:34.190 Now connect to your account. 03:36.110 --> 03:40.230 And from the list choose GPT four mini or GPT for all. 03:40.710 --> 03:43.510 For this particular example you can use GPT four mini. 03:44.070 --> 03:47.150 It will it will work great. 03:54.990 --> 04:02.740 Now next we add a simple memory so it stores in memory, so no credentials are required. 04:04.780 --> 04:05.700 Press on that. 04:07.660 --> 04:10.420 And here you can specify the context window length. 04:10.940 --> 04:16.220 So basically it means how many pass interactions the model receives as context. 04:16.700 --> 04:25.780 So in this setup how many messages it has to remember from the open chat. 04:28.060 --> 04:28.660 Feature. 04:29.340 --> 04:31.740 While we be interacting with it. 04:32.020 --> 04:33.260 So let's close it for now. 04:36.540 --> 04:40.060 And let's say we want it to remember ten messages. 04:43.020 --> 04:43.540 Great. 04:44.340 --> 04:49.540 Now let's connect our agent to a Gmail node. 04:50.340 --> 04:55.580 So we are going to create a tool which will be called by our agent. 04:56.380 --> 04:57.980 So we are going to use. 05:00.060 --> 05:00.940 Gmail node. 05:01.860 --> 05:02.860 So Gmail tool. 05:05.820 --> 05:07.900 And we want to send message. 05:08.420 --> 05:12.660 Just make sure you are connected to the correct Gmail account. 05:13.460 --> 05:15.220 So this is where the magic happens. 05:15.860 --> 05:21.700 So this tool is going to send emails on our behalf as the resource you have. 05:21.700 --> 05:24.700 Message sent because we want to send an email. 05:26.100 --> 05:30.940 So we need to fill in these fields to subject and message. 05:32.620 --> 05:34.420 And let me show you something cool. 05:35.140 --> 05:40.020 So this new feature lets you autofill those fields using AI. 05:40.340 --> 05:48.020 So instead, instead of writing manual expressions or hard coding anything, you just click the little 05:48.020 --> 05:55.540 purple purple button next to each field and it fills in the right info for you automatically. 05:55.780 --> 06:02.330 So it reads your prompt understands who the email is for what it's about, and write the message. 06:02.530 --> 06:04.250 So it's super fast and super clean. 06:04.730 --> 06:10.530 If you want a bit more control though, you can use the from OpenAI expression. 06:10.930 --> 06:19.690 So just to switch the field to the expression and write the expression programmatically, and I'm going 06:19.690 --> 06:24.610 to show you how to do this in the build your team of AI agents lesson. 06:24.690 --> 06:26.170 So now let's keep it simple. 06:27.410 --> 06:30.930 I'm just going to let the model define the parameter. 06:32.050 --> 06:33.850 So simply simply click on that. 06:34.090 --> 06:37.130 The same for the subject and for the message. 06:37.730 --> 06:39.370 Now let's add another tool. 06:39.930 --> 06:43.650 So Google Sheet to store our email addresses. 06:43.690 --> 06:46.370 We want to email two. 06:46.730 --> 06:52.050 So click on the tool again ad tool search for Google Sheet. 06:58.090 --> 07:03.730 Tool which allows for reading, updating and writing data to Google Sheets. 07:04.970 --> 07:05.810 Click on that. 07:06.650 --> 07:12.250 Now go to your Google Drive and create a simple Google Sheet. 07:15.810 --> 07:21.370 With two columns like Name and Email and enter some data. 07:25.130 --> 07:27.970 Then go back to connect to your Google account. 07:27.970 --> 07:30.610 So just simply click on this drop down. 07:31.330 --> 07:39.250 Create new credential and sign in with Google, which will automatically connect to your Google Sheets, 07:39.450 --> 07:43.610 and it will give your agent access to the Google Sheet you created. 07:44.810 --> 07:45.850 And hit save. 07:49.570 --> 07:50.370 Close it. 07:52.890 --> 07:57.400 So we want set it Automatically, not manually. 07:58.760 --> 08:02.520 So we are looking for a sheet within the document as the operation. 08:02.520 --> 08:04.760 We want to get rows. 08:04.880 --> 08:08.800 And here we want to select a document from the list. 08:09.320 --> 08:17.040 If you have connected to your Google account, the Google sheet you have created should pop up here. 08:17.840 --> 08:21.560 So now I'm going to refresh the connection. 08:42.640 --> 08:51.240 And now when I want to choose the document from the list, you can see I have access to contacts I have 08:51.240 --> 08:51.960 created. 08:52.320 --> 08:56.360 So this is this Google sheet with the context data. 08:59.160 --> 09:02.120 Now we want to choose a sheet within this document. 09:03.160 --> 09:04.480 So it's sheet one. 09:07.120 --> 09:08.920 It should pop up automatically. 09:09.680 --> 09:11.320 Yeah I'm going to choose this one. 09:12.320 --> 09:13.880 And that's it for for this node. 09:13.920 --> 09:15.960 Now let's go back to our agents. 09:19.080 --> 09:20.280 Let's open this node. 09:22.520 --> 09:24.840 And now we want to add a system prompt. 09:25.080 --> 09:29.200 So basically we want to guide our agent. 09:29.560 --> 09:30.840 What we want to achieve. 09:30.880 --> 09:34.200 So we want to provide instruction on what to do exactly. 09:34.800 --> 09:36.080 So click on add option. 09:36.880 --> 09:37.880 System message. 09:39.280 --> 09:41.440 And then switch to expression mode. 09:43.040 --> 09:44.160 And expand it. 09:44.800 --> 09:48.720 And now I'm going to copy and paste the prompt I have prepared. 09:54.040 --> 09:55.790 So this is our very simple prompt. 09:56.430 --> 09:58.590 So we define the role for our agent. 09:58.590 --> 10:01.390 So you are a professional personal assistant agent. 10:01.750 --> 10:06.110 Your primary role is to send emails and you have access to two tools. 10:06.110 --> 10:08.630 So contacts and email tool. 10:09.350 --> 10:11.590 So basically two tools we have created. 10:17.630 --> 10:20.870 And here we are describing how to use these tools. 10:21.430 --> 10:27.510 So contacts use this tool when you need to look up contact information like an email address or phone 10:27.510 --> 10:27.990 number. 10:28.390 --> 10:32.990 You need to use this tool before sending an email or before getting emails. 10:34.110 --> 10:37.310 And email tool you can add two here. 10:38.070 --> 10:44.070 I use this for image related actions like sending emails, reading emails, or forwarding emails. 10:44.350 --> 10:52.350 So basically you can add more tools to this agent if you want your agent to read emails for you and 10:52.350 --> 10:55.950 summarize them, etc. you can just simply. 10:58.030 --> 10:58.750 Add tool. 11:03.430 --> 11:03.870 Again. 11:05.270 --> 11:07.110 And here you just change the operation. 11:07.550 --> 11:12.630 So you can add label, delete, get, get many emails and so on. 11:14.430 --> 11:16.390 Now for this tutorial let's keep it simple. 11:16.390 --> 11:21.430 So I'm going to remove it and let's work on our prompt. 11:23.910 --> 11:28.550 So you want keep emails professional and format it nicely. 11:28.550 --> 11:32.030 So the body of the email with the line breaks and clear structure. 11:32.350 --> 11:35.870 And we always want it to sign off as best regards. 11:35.870 --> 11:36.550 And Damon. 11:36.790 --> 11:38.550 And here is the current time and date. 11:39.190 --> 11:44.870 So just to make sure that I will not make mistakes regarding the date and time. 11:45.270 --> 11:47.110 And now this is really important step. 11:47.430 --> 11:48.590 So please don't miss it. 11:48.590 --> 11:57.900 Because otherwise even if you will give very detailed description of the formatting style you want to 11:57.900 --> 11:58.420 get. 11:58.460 --> 12:05.140 Your agent will struggle to send emails properly formatted, so let's close it for now. 12:06.660 --> 12:08.620 And let's go back to our Gmail tool. 12:12.020 --> 12:19.580 And here make sure to switch to the text instead of HTML as the email type. 12:19.780 --> 12:28.860 Now, before we test our agent, we need to make sure that the name of our tools match the naming in 12:28.860 --> 12:29.660 the prompt. 12:30.860 --> 12:35.660 So our agent knows what tools to call. 12:37.260 --> 12:39.620 So we have contacts and email tool. 12:40.780 --> 12:41.980 So let's rename it. 12:43.020 --> 12:44.220 This is the Gmail tool. 12:49.420 --> 12:50.260 And confirm. 12:52.420 --> 12:53.610 Here you have contacts. 13:01.050 --> 13:03.650 Confirm and save. 13:05.370 --> 13:08.090 Now let's go ahead and test our agent. 13:08.530 --> 13:13.370 So open chat by clicking on this button and type something like. 13:15.610 --> 13:15.850 Hi. 13:15.890 --> 13:20.690 Can you please send an email to Damien that I need to reschedule our upcoming meeting, please. 13:21.850 --> 13:23.170 And now let's see it in action. 13:24.010 --> 13:25.690 So I'm going to send this message. 13:28.850 --> 13:33.450 So as you can see the contacts tool gets triggered. 13:33.490 --> 13:35.170 Then Gmail tools get triggered. 13:36.890 --> 13:41.730 And as a response we have I have sent an email to Damien requesting to reschedule your upcoming meeting. 13:42.010 --> 13:44.970 If you need any further assistance, feel free to ask. 13:45.930 --> 13:47.210 Now let's check my inbox. 13:48.570 --> 13:52.330 Yes, I got an email, so request to reschedule meeting there. 13:52.890 --> 13:54.410 I hope this message finds you well. 13:54.450 --> 13:57.930 I would like to discuss the possibility of rescheduling our upcoming meeting. 13:58.450 --> 14:02.130 Please let me know your available times and I will do my best to accommodate. 14:02.170 --> 14:03.530 Thank you for your understanding. 14:04.050 --> 14:04.850 Best regards. 14:04.890 --> 14:05.290 Damien. 14:05.330 --> 14:05.930 Brilliant. 14:06.450 --> 14:11.010 As you can see, this email was sent automatically with N810. 14:11.330 --> 14:13.490 Doesn't look great, so let's remove it. 14:13.890 --> 14:18.250 And we can simply do it by going to our agent. 14:19.130 --> 14:20.970 Let's close the chat for now. 14:21.890 --> 14:23.930 So let's open the Gmail Tools node. 14:26.050 --> 14:27.370 And scroll down. 14:28.450 --> 14:32.330 And here under options click on add option. 14:33.130 --> 14:34.890 Then open Anytime Distribution. 14:36.410 --> 14:37.450 And let's turn this off. 14:39.650 --> 14:46.170 And now when we send the next email this attribution will be removed. 14:47.290 --> 14:49.130 And we will have nicely formatted email. 14:50.050 --> 15:00.010 So yes if you want to interact with your agents via apps like WhatsApp, telegram, slack and others 15:01.210 --> 15:09.970 and ask it to send emails on your behalf to any contact details you store in the Google Sheet. 15:10.250 --> 15:17.010 Go to the How to Set up Credentials lesson, and you can find a separate tutorials where I explain how 15:17.010 --> 15:20.010 to connect different services to your agents. 15:20.210 --> 15:24.050 So this is a perfect starter agent to get hands on with. 15:24.090 --> 15:32.010 And the best part is it's fully customizable so you can build on top of it to write drafts, summarize 15:32.010 --> 15:38.650 emails, delay them, route them to Notion or Slack, or even plug in into your CRM. 15:39.010 --> 15:45.890 So in the next videos, we'll build something more advanced, but for now, try building this one. 15:45.930 --> 15:49.930 Click by click, get familiar with the tools and have fun with it. 15:50.050 --> 15:52.250 Thanks for your attention and see you in the next one.
