# Train a subject: you, a model, your product or brand

Subjects tell Hero_Photo who and what to put in your pictures: you, a model, your real product, and your brand's logo, colors and look. Add one with Train a subject, then pick it under Subject.

**Where:** Hero_Photo → **＋ Train a subject**, or the **You**, **Model** or **Product** chip under **Subject** → **＋ Train new…**

## What a subject is

A subject is someone or something Hero_Photo should put in your pictures exactly as they are: you, a model, your product, or your brand's look. You add it once, then pick it under **Subject** whenever you make a picture. Presets that need a person or a product use your saved ones.

"Subjects stay private to this workspace. Hero_Agent can use them too."

| Subject | What it's for | What you give it | Cost |
|---|---|---|---|
| **You** | "Put yourself in any shot — headshots, lifestyle, your product in your hands." | 5 to 20 photos of you | See [Add yourself](#add-yourself) |
| **Model** | "A consistent model for your brand — pick a ready-made one, design one, or use photos of a real model (with their permission)." | Pick one, design one, or 5 to 20 photos | Ready-made: free. Designing: 8 credits for each round of four faces. |
| **Product** | "Your product, true to life, in any scene — worn, held or on a table." | 1 to 5 photos, or a link to its product page | Free, ready right away |
| **Brand** | "Your logo, colours, fonts and look — so every image is on-brand." | Your website, or your logo, colors, fonts and brand photos | Free |

## Add a product

1. Press **＋ Train a subject** → **Product**.
2. Choose where the photos come from: **Upload photos** (1 to 5 angles on a clean background), **From Shopify**, or **Product link**.
3. For **From Shopify** or **Product link**, paste the product page's address and press **Import**. Heropost takes the product's photos and name from the page; your store isn't connected. Remove any photo that isn't this product.
4. Press **Continue**.
5. Fill in **Name** (for example "Classic Sneaker — White"), **Type** and, if you like, **Keep exactly (optional)**, for example "logo on the side, gum sole, matte finish".
6. Press **Save product**. It's ready right away, under **Product**, **Try-on** and **Hold product**.

**Good product photos:** front, side and details. **Avoid** other products, glare and hard shadows, and screenshots.

## Add yourself

1. Press **＋ Train a subject** → **You**.
2. Drop 5 to 20 photos of yourself, or click to pick them. Each photo is checked as you add it (table below).
3. Watch the meter: 5 good photos to start, 8 or more for a closer likeness, 12 is best (8 close-ups and 4 full-length).
4. Press **Continue**.
5. Fill in **Name** and **This is a** (**Man**, **Woman** or **Person**). **Appearance** (age, hair, eyes) and **Anything to keep exactly? (optional)**, such as "beard, glasses, tattoo on left arm", help keep the likeness.
6. Tick the consent box (see [Consent and privacy](#consent-and-privacy)).
7. Read the box above the button, then press the button.

| Mark | Meaning |
|---|---|
| ✓ | A good photo |
| ! **Blurry** or **Low resolution** | Used, but not counted as a good photo |
| ✕ **Duplicate**, **Too small** or **Unreadable** | Not used |

**What works:** a clear face, half-body and full-length shots, different outfits and places. **Avoid** sunglasses and hats, other people, filters, blurry photos and the same outfit every time. Sharpness, size and duplicates are checked automatically; the rest is up to you.

What happens when you press the button depends on what the box above it says:

| The box says | The button | What happens |
|---|---|---|
| "**Ready right away.** Hero_Photo uses these photos to keep the likeness." | **Save** | You're saved at once, and Hero_Photo uses your photos as a reference in each picture. Free. |
| "**Training takes about 15 minutes · uses {n} photo credits.** Keep working — we’ll tell you when it’s ready, with 8 starter photos on the house." | **Start training** | Hero_Photo trains a likeness of you. The credits are used when training starts and come back if it fails. When it's ready, Heropost says "{name} is ready — 8 starter photos are in Create." The free starter photos stay at the top of **Create** for 3 days. |

While a likeness trains, your chip shows a progress ring. If training fails, the chip offers **↻ Retry training**. If a trained likeness lapses, your photos are used as references until you choose **↻ Refresh likeness**. Each shows its credit cost.

## Add a model

Three ways, under **＋ Train a subject** → **Model**:

- **Ready-made:** pick Elena, Maya, Daniel, Priya, Kenji, Linda, Mateo, Layla or Jalen, then **Use {name}**. "Made by Hero_Photo — not real people, so there’s nothing to consent to. They’re the same models you see in the preset previews." Free.
- **Design a model:** choose gender, age, style and skin tone, then **Show me 4 faces**. A round of four faces uses 8 credits, and the faces also land in your library. Pick one, name it, and press **Lock this model**, or **Show me 4 more**. "Don’t design a lookalike of a real person."
- **From photos of a real model:** the same steps as [Add yourself](#add-yourself), with 5 to 20 photos of the model and the model consent box. Use this to add a teammate.

## Set up your brand

**＋ Train a subject** → **Brand** opens the brand kit: import from your website, then check your logo, colors, fonts, brand photos and look words, and press **Save brand kit**. Your brand photos and look words become the **Brand** subject, used as a style reference. Only owners and Admins can change the brand kit, and it's on a computer or tablet only. Full steps: [Teach Hero_Agent your brand](/docs/ai/brand-kit-and-knowledge/).

## Use a subject

- Under **Subject**, click a chip to pick that type; it selects your newest saved one. Click the chip again to choose another from the list.
- **Brand** uses your brand look as a style reference. **You**, **Model** and **Product** put that subject in the picture.
- Using a preset that needs a product or a person you haven't added opens **Train a subject** on the right type.
- **Hero_Agent** can use your subjects too, for example "Make a photo of me holding our new mug". It can also save a product from photos already in your Media Library.

## Delete a subject

1. Click the subject's chip under **Subject**, then **Delete {name}…**.
2. Read the message, then press **Delete**.

- **A person (you or a model):** "Their photos and trained likeness are deleted for good, and Hero_Photo stops using them. Images you already made stay in your library. This can’t be undone."
- **A product or brand look:** "It will be removed from Hero_Photo. Images you already made stay in your library. This can’t be undone."
- A picture still being made with that subject stops, and its credits come back.

## Consent and privacy

To save a person, you tick one of these boxes. It links to the **Likeness terms**.

- **You:** "These are photos of **me**. I’m 18 or older and not a politically exposed person. Heropost doesn’t verify this — I’m responsible for it. I agree to the Likeness terms."
- **A real model:** "I have this person’s **explicit written consent** to create AI images of them. They’re 18 or older and not a politically exposed person or public figure. Heropost doesn’t verify this — I’m responsible for it. I agree to the Likeness terms."

Subjects stay private to the workspace they're saved in. Deleting a person deletes their photos for good.

| Limit | Value |
|---|---|
| Photos per subject | 20 |
| Subjects per workspace | 100 |
| Subject names | Up to 100 characters, unique in the workspace |
| Who can save subjects | Owner, Admins and Editors (not Viewers) |

| "The trainer couldn't use these photos. Try again with clear, well-lit photos of just this person — nothing was charged." | Training failed. | Use clearer photos of that person alone, then **↻ Retry training**. |
| "A subject in this photo was deleted after it started, so it wasn't made. Nothing was charged." | You deleted a subject while a picture of it was being made. | Pick another subject and generate again. |

## Questions

**Can I add a teammate?**

Yes. Add them as a **Model** from their photos, with their explicit written consent. Training **You** is only for the account owner.


**Is adding a product free?**

Yes. Products, ready-made models and the brand kit are free. You pay only for the pictures you make.


**Can other workspaces see my subjects?**

No. Subjects stay private to the workspace they're saved in. To use one in another workspace, add it there too.


**What happens to pictures I made if I delete a subject?**

They stay in your library and in any posts that use them.


**Can I use a photo of a celebrity or a public figure?**

No. The consent box for a real model confirms they're not a public figure, and designed models must not look like a real person.
