Build Your Own JARVIS with Jev (INSANE)

0:00Hey Jeff, can you open up Spotify for

0:01me, please?

0:03>> There you go, Spotify.

0:07>> Hey Jeff, can you play the song for me

0:08in Spotify?

0:10>> Playing.

0:12>> Hey Jeff, can you turn down the volume

0:15in Spotify and then open up [music]

0:17Slack for me, please?

0:21>> All done.

0:23>> Amazing. Uh hey Jeff, can you set a

0:25reminder to call Bob in 5 seconds,

0:27[music] please?

0:30>> Got it. I'll remind you.

0:35Hey, it's time to give Bob a call.

0:38>> Hey Jeff, uh can you now uh tell me who

0:41wrote Hamlet?

0:42>> William Shakespeare wrote Hamlet, one of

0:44his most famous tragedies from the early

0:461600s.

0:48>> Uh hey Jeff, can you now uh

0:50close down or lock down my computer,

0:51please?

0:53That's cool.

0:54>> Screen's locked.

1:00>> And there you go, it's locked.

1:02How insane is that? Now, I'm just going

1:05to get it to close stuff. Hey Jeff, can

1:06you close down my Slack and Spotify?

1:09>> Both sorted.

1:11>> That's so It is so bloody cool. This is

1:13one of the coolest and best things I

1:15think I have ever built. In this video,

1:18I'm going to break down exactly on how

1:20you could use it and potentially on how

1:22you could build it yourself. So, stick

1:24around and let's get to it. All right,

1:27so to make this work, we need at the

1:28bare minimum these three main things.

1:32Number one is we need Fish Audio, which

1:34is the sponsor of this video, and the

1:36voice that you heard was Hannah, and

1:37she's got that like super chill,

1:39realistic voice. And if you guys would

1:41have want to check out some of the other

1:42ones, Celine sounds really cool, Sarah

1:44sounds uh awesome, too. You know, if you

1:46are thinking of using something like

1:47this, like a like a your your own

1:49Jarvis, and you want like a male voice,

1:51you could certainly come in here and

1:52choose a male voice. You could even

1:53create your own voice it within here.

1:56So, you could clone your voice, you just

1:57have to talk to it for like 1 minute. I

1:59actually recorded myself in here before

2:01and I cloned my voice. So, if I for

2:02example say Henrik, I'm going to

2:04generate speech.

2:06Henrik.

2:07Henrik. FYI, if you're thinking like,

2:09"Yeah, I'm going to need to pay for one

2:10of those subscriptions." No, that is not

2:12true. Right now, official audio is

2:13currently for free. So, you can use it

2:16at least up until the end of November

2:182026 using this specific line, S2.1 Pro

2:24free. I think the only thing you have to

2:25pay for is this next thing, which is

2:27Jev.

2:28>> My name is Yeah.

2:29>> And it is a way to help us grab our

2:32commands or questions into a spot where

2:35something creates decisions for us. And

2:38these decisions get then turned into

2:39action for us on our computer. So, for

2:41example, before I said, "Hey, can you

2:43open up Spotify for me, please?" And it

2:45opened that up. Then it created a

2:47decision for itself. Does the user want

2:49to open up Spotify? Answer is yes. Then

2:51it would go and open that up. But, "Hey,

2:53can you open up Spotify for me, please?"

2:55>> Spotify, opening now.

2:57>> And um if you guys do want to learn more

2:58about it, I'm sure there's like a crap

3:00ton of videos out there right now on

3:02explaining on what Jev is. It is

3:04essentially our back end that controls

3:07the actions that we want it to take.

3:09What I would recommend getting is this

3:12thing called Open Writer. From here,

3:13you're going to be able to get an API

3:15key. And this API key lets us set up a

3:17fallback for things like

3:20when I asked it for example about

3:22Hamlet, when it can't take actions on my

3:24computer and it's outside of like its

3:25scope. What it's going to do is think,

3:27"Hey, I can't really answer this

3:28question." So, then it's going to go and

3:31ask an actual LLM.

3:33So, you guys can choose any LLM that you

3:35like. You can choose Haiku, you can

3:36choose Gemini models, you can choose

3:38your llamas or whatever you want. And

3:40you can get the LLM to create you the

3:43response. Now, I also, if you notice for

3:45the

3:46for the timer, it actually responded

3:48back to me very nicely. So, for example,

3:50if I say, "Hey Jev, can you uh tell me

3:52to book an appointment in uh 3 seconds,

3:55please?"

3:56>> Sure. I'll give you a shout.

4:02Hey, it's time to book that appointment.

4:04>> particular case, that was a timer that

4:07got sent through

4:08uh Jeff, then that got sent through uh

4:11I'm actually using a Haiku 4.5 just cuz

4:13I really like that model. Now, to some

4:15of the use cases that I think would be

4:17awesome for this. Um number one is what

4:19we were using just then, right? So,

4:22uh computer use / control.

4:25Uh later, I think this could be taken

4:27into like writing your own emails for

4:31you. I was just really excited,

4:33honestly, to get it to turn into an icon

4:36on my on my Mac.

4:38Uh have it open up in my dock. Um so,

4:40I'm sure you guys can think of uh more

4:43exciting things that you want to use it

4:44for your own computer use, for whatever

4:47you guys want to use that for. Another

4:48cool one would be like uh house control

4:51system. Instead of Siri or Alexa, you

4:53could be using this setup, which would

4:56be for free and running on your local

4:59setup, by the way. So,

5:01uh where when I'm running it from right

5:04here,

5:05it's actually not going the or the

5:07transcript is staying on my machine. So,

5:10we're actually using I'm just going to

5:11write here.

5:12We're using a small Whisper model, which

5:15only takes up maybe like 250 MB to run.

5:19Do an uh check every so often to see

5:21whether I've said, "Okay, Jeff." or

5:23"Hey, Jeff." And by the way, that's

5:24totally uh changeable. So, anyway, uh

5:26going back, house control system, uh you

5:28know, you could say instead of me like

5:30saying, "Hey, hey, Jeff, open up

5:31Spotify." you could say, "Hey, Jeff, can

5:33you turn on the living room lights?"

5:34Then, you could potentially use it, you

5:37know, as like a uh disability kind of

5:39helper to help you control your computer

5:41a little bit better. However, for me,

5:43what I actually would like to use a

5:45four, be to what do multitask. Hey Jeff,

5:48can you open up Spotify for me while I'm

5:50smoking? I don't have to like come to my

5:52computer and you don't press buttons. So

5:54multitasking, opening up stuff, and

5:56potentially lessen the screen time.

5:59If you guys can think of any other cool

6:00use cases, just put them down in the

6:01comments below. Now, we are going to get

6:03into the juicy stuff. So, if you are a

6:07person loves building this stuff, loves

6:09Claude code, Codex, stick around and I'm

6:11going to show you on more or less on how

6:14to put this together. So,

6:16number one step is you need an IDE. So,

6:20you could use Cursor, you could use any

6:22other IDE that you like. What I'm going

6:24to do is go down into the description

6:28and then grab this.

6:31Then,

6:32come back into Cursor, you're going to

6:34go clone repo, and then you're going to

6:36put that into any folder that you like.

6:38So, for example, I could put in my life

6:40get folder and I could select that as my

6:42repository destination. It's going to

6:43open that up for me.

6:45And now I have that project that I

6:47created for you guys. You can either

6:49follow the steps or you could just get

6:51your Claude code or Codex to set it up

6:53for you. So, for instance, you know, you

6:55would come into here, you would just

6:57type in Claude,

6:59and say yes.

7:01Then, you would grab this. You just

7:04copy this paragraph right here.

7:06You paste that in, press enter, and it's

7:08going to do all the magic for you. So,

7:11if you came here and you're like, "Hey

7:12Henrik, I'm using your Windows. Why the

7:14hell would I be watching you build it on

7:16your Mac?" Well,

7:18easy fix is,

7:20you know, you copy this

7:21and you say,

7:23uh

7:24"This guy was using uh this on his Mac

7:27and he everything so that it works here

7:28on my Windows desktop." And then just

7:29let it just let it rip. The things that

7:31you will need is your API key. So, I'm

7:33just going to show you real quick where

7:34they roughly exist. Uh you will then

7:36come into uh developer in Fish Audio.

7:39You will click on create API key. You

7:41click on create, copy that.

7:43Then go to typesafe.com, you apply if

7:46you don't have the if you don't have

7:48your API key yet. They exist right here

7:51though if you do. So you click on create

7:53API key, you create it, you copy that as

7:56well.

7:57Then you would come into open router,

7:59you'd come into something that looks

8:00like this. So you click on API keys on

8:02the left top right here. You would copy

8:05the API key. So once you got those three

8:08things, once you got your app working

8:10and you've you know you've discussed a

8:12little bit with the Codex and Claude,

8:13you come into this button right here

8:15that says keys. You press that and it

8:17opens up this new window

8:19you just paste all your respective keys

8:21into here. You press save. That gets

8:24saved to your Mac OS keychain. So like

8:26no LLM or whatever sees it so everything

8:28stays safe on your in your environment.

8:31So at the moment I believe Type Safe is

8:32actually for free. I haven't set up any

8:35payment methods on it. So I've been

8:38using a so I've used 1. 3 million tokens

8:41and it's cost me what's that? 4 cents? 5

8:44cents? I was telling you guys S2 1.3 is

8:47now free for developers. So if you just

8:49I jump into here. I guess the only thing

8:51that I should really worry about is that

8:53when you create this app it's going to

8:54ask you for some permissions. So you

8:56might have to go and like click allow to

8:57use the microphone. Allow to open up

9:00Spotify for you. And then once you've

9:02got it working

9:04mine for example was put into a DIST

9:08folder as an icon like this. And then I

9:10just click on this and it just opens up

9:12the app for me. And then you can choose

9:14between hold option and then hey Jeff

9:16option. So thank you guys for watching.

9:18If you would like to sign up to Fish

9:19Audio I will

9:21I will give you absolutely nothing for

9:22it. Is there's a referral link down

9:24below. If you're like someone out there

9:26who just doesn't want to build this

9:27stuff for yourself then want someone

9:29like me to come in and just help you do

9:30it. You're more than welcome to also

9:31just book a call with me as also

9:33available right below.

9:36Anyway, thanks guys for watching and see

9:37you next one. Peace.
