Overview

Siren, brayv.ai's AI ad strategist, is the easiest way to launch a high-performing Facebook and Instagram ad - even if you've never run an ad in your life. Instead of filling out a long form, you have a quick conversation. You tell Siren what you want to advertise, and it does the heavy lifting: it researches what's working for businesses like yours, writes your ad copy, designs eye-catching images and videos, sets up your lead capture, and assembles the whole ad for you.

You stay in control the entire time. Everything Siren builds appears in a live preview on the right that you can edit at any point, and nothing goes live until you click Launch Ad.

Why use it:

• No ad experience needed - Siren guides you one question at a time.
• Smarter, not just faster - it researches real competitor ads and your website to make informed choices, instead of relying on you to know best practices.
• Better creative - it generates scroll-stopping designed graphics and videos, and can even include your logo and your own product photos.
• You're always in control - review and edit copy, media, targeting, and budget live, and launch only when you're happy.

Estimated time to complete: 5-10 minutes (plus a few minutes in the background while media generates)

Getting Started

Prerequisite: Connect your Facebook account first (Settings > Integrations > Meta (Facebook) Ads & Lead Forms). See Launch a Meta Ad with AI for the connection steps - they're the same for both builders.

1. Click AI Marketing (sparkles icon) in the left-hand menu.
2. Open AI Ads.
3. Click the Create Ad with Siren card ("An AI strategist researches, writes & designs your ad with you").
4. Just respond to Siren. Siren will walk you through the whole process, doing all the heavy lifting for you.

Tip: You can leave at any time and come back later. Your ad and the full chat history save automatically as a draft. Reopen it from Drafts on the AI Ads page and pick up right where you left off.

What Siren Will Walk You Through

You don't need to memorize these steps - Siren leads the conversation. This is simply what to expect and the choices you'll get to make along the way.

1. The basics

Siren confirms your business name, asks where you're located, what one product/service/offer you want to advertise, and your "next step" - what you hope a lead does after they reach out (get a free estimate, book a consultation, etc.). This keeps your whole ad focused on driving that action.

2. Ad category

As soon as it understands your offer, Siren determines whether your ad falls into one of Meta's special categories (Housing, Employment, or Financial products and services) and tells you its call in plain language. Most ads aren't special. You can always review or change this under Ad Category in the right-hand panel.

At the same time it decides whether the ad should skip people who already completed a job with you: on for one-time work (installations, replacements, major purchases), off for routine service a past customer would buy again. It tells you its call in one sentence; change it under Audience in the panel. Brayv keeps the past-customers list current from your CRM, and leads you're still talking to are never skipped. (The first time, Facebook needs a one-time permission from the business; your ad launches either way and Siren offers to switch this on afterwards. Special-category ads never use this setting.)

3. Research

This is what makes Siren different. It researches real, currently-running ads from businesses like yours to learn which hooks, offers, and formats are actually working, and it reads your website for context. It'll share what it learned so you understand the "why" behind its suggestions.

4. Media (images & video)

Siren handles media early so it can generate in the background while you finish the rest. You'll choose:

• Use your own - select photos/videos from your media library (you can upload new ones too).
• Let Siren create them - it proposes a set of creative concepts for you to approve.

If you choose AI generation, you'll get a couple of helpful options:

• Reference images - click the image button next to the chat box to add a photo for Siren to use (for example, a specific product to feature, or a person to keep consistent across images). You'll give it a quick label and tell Siren how to use it. Siren can see your photo and work it into the designs.
• Your logo - if you've saved a logo under Settings > Business, Siren already has it and can place it on the images for you.

Siren then proposes media concepts (designed graphics and videos). For each one you can expand to see - and edit - the full prompt before generating, so you know exactly what you're getting. Pick the ones you like and Siren generates them. Images take under a minute; videos take a few minutes and finish in the background.

Tip: A mix of images and video performs best. Siren aims for a strong set of 8-10 assets, but you can ask for more, fewer, or a different style at any time. Facebook allows up to 10 per ad.

5. Ad copy

Siren writes your headlines and primary text itself, grounded in its research. First it asks about your preferred tone (just describe it - "bold," "warm and local," "premium," anything) and whether to use emojis. It then writes several variations (up to 5 of each) with a strong hook and a clear call to action tied to your "next step." Edit any of it in the right-hand panel.

6. Where your leads go

Siren helps you pick the best lead-capture method:

• You have a dedicated landing page with a lead form on it → Siren can send traffic there.
• You don't (most businesses) → Siren sets up a Facebook lead form so people can submit their info without leaving Facebook. You can pick an existing form, fill one out yourself, or have Siren build one for you. Forms Siren builds ask for name, email and phone, turn on phone verification so the numbers you get are real, and need your privacy policy link and website address.

Tip: Don't run ads to a generic homepage - it's one of the most common mistakes. A focused lead form or a dedicated landing page converts far better.

7. Targeting & budget

You select your target location(s) under Targeting in the right-hand panel - you know your service area best, so this stays in your hands. Siren recommends a territory and sets the age/gender, and you'll see a live estimated audience size. Siren suggests a daily budget and names the campaign for you; review or change both on the right. (For special-category ads, Facebook's restrictions are applied automatically: ages 18-65, all genders, and whole cities or areas with at least a 15-mile radius instead of zip codes.)

8. Review & launch

When everything's in place, Siren lets you know your ad is ready to launch and invites you to review the whole thing on the right. The Launch Ad button activates once nothing is missing, any media has finished generating, and the ad has no more than 10 images and videos. Make any final edits, then click Launch Ad. Brayv builds the ad on Facebook and turns it on for you; Facebook reviews it before it starts showing.

The Live Preview Panel (Right Side)

Almost everything Siren builds shows up on the right and can be edited there - you're never locked into Siren's choices:

• Copy - edit headlines and primary text
• Media - add, remove, and preview images/videos
• Ad Category - review or change the special category
• Audience - whether people who already completed a job with you are skipped
• Targeting - location, age, gender, and audience estimate
• Budget & Goals - daily budget, campaign name, call-to-action button

The ad's goal and where leads go (lead form or landing page) are decided in the chat and shown on the right as read-only. Mix the chat and the panel however you like: Siren handles most of the build, and you pick the locations and fine-tune anything else yourself.

After Launching: Connect Your Leads

Important: After launching, make sure your leads flow into brayv.ai properly:

If using a Facebook lead form: Right after launch you'll see a One more thing prompt. Click Set it up to connect the form to brayv.ai and choose the journey its leads should enter. Until the form is connected, its leads stay in Facebook and don't reach brayv.ai. You can also do this later under Settings > Lead Sources.

If sending leads to a website: Ensure the landing page has a form (brayv or 3rd party) displayed prominently, and that form is configured in Lead Sources to route leads into an AI journey.

Improving a Live Ad with Siren

When Siren recommends a change on the AI Ads Performance page (fresh creative, a second set of ads, a follow-up ad), accepting it opens Siren already looking at your live ad. The button at the bottom then reads Apply to ad, Add to campaign, or Launch follow-up ad instead of Launch Ad, and your changes go into the existing campaign. See Ad Performance and Campaign Management.

Key Tips

Just talk to it like a person. You don't need marketing jargon. Describe your business and offer in plain language and answer Siren's questions - it handles the strategy.

Be specific about your offer. "New water heater installs, 20% off this month" works far better than "plumbing services." Specific offers help Siren research, target, and write copy that actually converts.

Give it your photos and logo. Reference images (a real product, your team, your storefront) and your saved logo make AI-generated creative look authentically yours. Add references with the image button by the chat box.

Review the full idea before generating. Expand any media concept to read - and tweak - the exact prompt Siren will use. It's the easiest way to get media you love on the first try.

Edit freely on the right. If you'd rather change something yourself than ask Siren, just do it in the panel.

Drafts save automatically. Leave whenever you want - your ad and the entire conversation are saved. Media that's still generating will continue in the background and be waiting for you when you return.

Do I need a Facebook Pixel? No setup needed. When you connect Facebook, brayv.ai picks your ad account's pixel (or creates one if there isn't one) and adds its own tracking events to it. brayv.ai then automatically sends every lead, first reply, converted lead (a lead that reached your journey's goal, like a booked appointment), and opportunity won back to Meta behind the scenes, so its algorithm gets smarter about who to show your ads to over time - lowering your cost per lead. Installing the pixel on your website is optional.

Prefer the manual builder?

The original step-by-step ad builder is still available - click Manual creation with AI assistance on the AI Ads page. We recommend Siren for most users because it researches your market and does the heavy lifting for you, but the manual builder gives you a traditional form-based flow if you prefer it. See Launch a Meta Ad with AI.
