The single biggest difference between "AI captions sound generic" and "AI captions sound like our brand" is whether you filled in Brand DNA properly. It is the questionnaire Manva uses to teach the AI what your business sells, who you sell to, what tone you write in, and what words you use (and avoid). Spend 15 minutes here and every caption, every blog post and every WhatsApp message gets dramatically better.
What Brand DNA actually controls
When you generate a caption or blog post, Manva quietly attaches your Brand DNA in the background. This affects:
- The vocabulary the AI picks (formal vs casual, English vs Hinglish, technical vs everyday)
- The product positioning ("hand-poured candles for slow living" vs "scented candles in 12 fragrances")
- The audience the AI writes for (gen-Z vs working professionals vs aunties)
- The CTAs ("DM us" vs "shop now" vs "book a consultation")
- Forbidden words and topics you never want associated with your brand
Where to find it
From the dashboard: Settings → Brand DNA, or use the shortcut from any caption-generation screen.
The first time you open it you see a guided questionnaire. After that, it becomes an editable profile you can update any time — useful when you launch a new product line or pivot your audience.
Section 1: The basics
- Brand name — exactly as you want it written (capitalisation matters)
- One-line description — like a Twitter bio. "Hand-poured candles for slow living, made in Pune"
- Founded — the year you started, used in About-us-style content
- Location — the city you operate from. Drives local references in captions.
Spend the most time on the one-line description. The AI re-reads it before every generation. A vague line ("we sell stuff online") makes generic captions; a sharp one ("hand-poured candles for slow living, made in Pune") makes captions that sound like you wrote them.
Section 2: What you sell
List your top 3–5 products or services as bullet points. For each, include:
- The product name
- The price band (e.g. ₹399 to ₹1,299 per candle)
- One sentence about what makes it different
This is the difference between an AI caption that says "our amazing products" and one that says "the lavender soy candle, ₹599, burns clean for 40 hours".
Section 3: Your audience
Three questions:
- Who buys from you? — describe in one paragraph. Age, profession, lifestyle, what problem you solve for them.
- Where are they? — city, state, urban vs small-town, Indian vs NRI, etc.
- What do they care about? — values, aesthetics, price sensitivity, language preference
The more specific, the better. "Working women in their 30s in Bengaluru and Hyderabad who care about sustainable products and are willing to pay for quality" is far more useful than "women aged 25–45".
Section 4: Your tone
Pick from preset combinations or describe in your own words:
- Formality: Casual / Friendly / Professional / Premium
- Energy: Calm / Warm / Excited / Bold
- Voice: First-person ("I love this fabric") vs Brand-voice ("we love this fabric") vs Customer-voice ("our customers love this fabric")
- Language mix: English only / Hindi only / Hinglish / Other regional
If you have written captions yourself in the past, paste 3–4 of your favourites into the "Voice samples" box. The AI uses them as reference for new captions.
Section 5: Words and rules
Two important fields most people skip:
- Words to use — your brand-specific vocabulary. "Slow living", "small-batch", "artisanal", "made-to-order".
- Words to avoid — vocabulary that does not match your brand. "Cheap", "Insta-famous", "girl-boss", anything outdated or off-brand.
Manva treats these as soft preferences (the AI tries to honour them) but the discipline of filling them forces you to articulate your brand voice in a way that benefits every other channel too.
Section 6: Hashtag preferences
Save your standard hashtag bundles by category. For example, a fashion brand might have:
- Always-on — #SlowFashion #IndianBrand #MadeInIndia
- Festive — #DiwaliEdit #FestiveOOTD
- Reels — #ReelsIndia #ContentCreatorIndia
When you generate a caption, Manva offers the right bundle automatically based on the post type.
Tying it all together
Once Brand DNA is filled in, every AI generation across Manva — captions, blog posts, WhatsApp broadcasts, even AI image prompts — uses your DNA. You will notice the difference in the very first caption you generate.
Updating it
Brand DNA is not set-and-forget. Update it when:
- You launch a new product category
- Your audience shifts (e.g. you start selling outside your home city)
- Your tone changes (e.g. you go from "fun and casual" to "premium and considered")
- You realise the AI keeps producing something off-brand — usually a sign that DNA needs to spell out the rule
Frequently asked questions
How long should I spend on this? 15–30 minutes for a first version, then 5 minutes when you update it later.
Do I need separate Brand DNAs for separate brands? Yes. Manva supports multiple brand profiles — useful for agencies running several clients or for businesses with multi-brand portfolios.
Will the AI follow it 100%? No — it is a strong preference, not a hard rule. You will still want to edit captions occasionally. But the difference between "lots of edits" and "minor tweaks" is whether DNA is filled in.
Can I import a brand book? Not yet. Paste the relevant sections (tone, vocabulary, do/don't) into the appropriate Brand DNA fields manually.
Brand DNA is the most under-used feature in any AI marketing tool. The 15 minutes you spend here pay back every single caption you generate from then on.
