Ask any AI to write an ad and it will write a good ad for nobody in particular. Upbeat, polished, full of words like "elevate" and "effortless". Your brand doesn't sound like that. Or if it does, so does everyone else's.
The fix is to tell the AI who you are, specifically enough that it has no room to fall back on its defaults. In AdVideoLab that's the brand voice profile. Here's how to fill it in so it actually changes the output.
Start from your website, then correct it
The fastest start is to paste your website. AdVideoLab reads the headline, product copy, benefits and tone and drafts a profile. It's usually 70% right. The other 30% is where your brand lives, so take ten minutes to correct it.
The fields that matter most
Not every field carries the same weight. These change the output most:
| Field | Why it matters | Weak | Strong |
|---|---|---|---|
| What makes you different | The AI builds hooks from this | "High quality" | "Every case is stitched by hand in Porto and takes four hours" |
| Customer's own words | Makes the script sound like the buyer | "Customers love our product" | "I'm done replacing plastic cases every six months" |
| Pain points | Feeds problem-first hooks | "Phones break" | "Cards fall out of cheap wallet cases" |
| Words you never use | Stops generic copy | nothing | "luxury, elevate, game-changer, must-have" |
| Tone | Sets rhythm and formality | "Friendly" | "Dry, confident, a little understated. Never exclamation marks." |
| Past winning scripts | The strongest signal of all | nothing | Paste the voice-over from your best-performing ad |
Borrow your customers' language
The best source for brand voice isn't your marketing team, it's your reviews. Read your five-star and three-star reviews and copy the phrases people actually use. "It's aged really nicely." "I finally stopped carrying a wallet." Those lines make better hooks than anything a copywriter invents, because they're how buyers already think.
Ban the words that make you sound generic
Every brand has words it overuses. Every AI has words it overuses too. Put both in the banned list. AdVideoLab checks the brief it writes against this list and flags anything that slips through, so you catch it before it's in a video.
Name your competitors
If there are brands you never want mentioned or imitated, list them. The AI won't reference them, and the brief lint will warn you if a name appears.
Use the tone slider for one-off changes
Sometimes a single ad needs to be more playful or more serious than your usual voice. Rather than editing your profile, use the tone slider on the generation page. It shifts that one brief without changing your brand settings.
Let your results train it
After a video runs, rate it in your project history. Four and five-star briefs become examples the AI studies next time it writes for your brand. After a few rounds, the first draft is much closer to what you'd have written yourself.
A quick test
Fill in your profile, then generate a brief for one product. Read the voice-over out loud and ask: could a competitor run this exact ad with their logo on it? If the answer is yes, the profile needs more specifics. Add a sharper difference, a real customer phrase, or a past winning script, and try again.
