👨‍💼 Headshot AI - Professional Headshots with AI (powered by Astria.ai)

Introducing Headshot AI, an open-source project from Astria that generates Professional AI Headshots in minutes.

This project was built to give developers & makers a great starting point into building AI applications. This is your launch pad - fork the code, modify it, and make it your own to build a popular AI SaaS app.

How It Works

Live demo here.

The app is powered by:

• 🚀 Astria for AI model training & inference
• ▲ Next.js for app and landing page
• 🔋 Supabase for DB & Auth
• 📩 Resend (optional) to email user when headshots are ready
• ⭐️ Shadcn with Tailwind CSS for styles
• ▲ Vercel for deployments
• 💳 Stripe for billing

Running Locally

To create your own Headshot AI app, follow these steps:

Note Training models is only available on paid plans. You'll need an active Astria API Key to train models.

1. Vercel template

To setup Supabase/Vercel and your github repo, click on the Vercel Deploy Button and follow the steps.

IMPORTANT: In the Supabase integration step: Make sure you leave the Create sample tables option checked. This might take a few minutes to complete.

The Vercel Deployment will create a new repository with this template on your GitHub account and guide you through a new Supabase project creation. The Supabase Vercel Deploy Integration will set up the necessary Supabase environment variables and run the SQL migrations to set up the Database schema on your account. You can inspect the created tables in your project's Table editor.

This will create the tables with their respective columns and RLS policies:

• credits
• images
• models
• samples

2. Clone your newly created repo:

git clone {{your-repo-name}}

3. Enter your newly created repo's directory:

cd {{your-repo-name}}

4. Install dependencies:

For npm:

npm install

For yarn:

yarn

5. Magic Link Auth (Supabase)

In your supabase dashboard, select newly created project, go to Authentication -> Email Templates -> Magic Link and paste the following template:

<h2>Magic Link</h2>
<p>Follow this link to login:</p>
<p><a href="{{ .SiteURL }}/auth/confirm?token_hash={{ .TokenHash }}&type=email">Log In</a></p>

Then, make sure to setup your site URL and redirect urls in the supabase dashboard under Authentication -> URL Configuration.

For example:

Site URL: https://headshots-starter.vercel.app

Redirect URL: https://headshots-starter.vercel.app/**

6. Create a Astria account

In your .env.local file:

• Fill in your_api_key with your Astria API key
• Fill in your-webhook-secret with any arbitrary URL friendly string eg.shadf892yr398hq23h
• Fill in your-vercel-url with a url to catch webhooks from Astria. This will be your vercel deployment url or Ngrok tunnel locally (eg. https://{your-hosted-url}/astria/train-webhook)
• Fill in your-blob-read-write-token with your Vercel Blob token (steps below)

If your production webhook callbacks do not seem to be working, make sure the callback URL is not of a Vercel dedicated branch deployment which requires authentication, in which case you will not see the callback in the logs.

7. Configure Vercel Blob for image uploads

In your Vercel project, create a Blob store

• In your Vercel dashboard, select the Storage tab, then select the Connect Database button.
• Under the Create New tab, select Blob and then the Continue button.

Then to configure in your .env:

• In your Vercel dashboard, select the Settings tab, then select the Environment Variables tab.
• Copy your BLOB_READ_WRITE_TOKEN to your .env

8. Create a Resend account (Optional)

• Fill in your-resend-api-key with your Resend API Key if you wish to use Resend to email users when their model has finished training.

9. Configure Stripe to bill users on a credit basis. (Optional)

The current setup is for a credit based system. 1 credit = 1 model train.

To enable Stripe billing, you will need to fill out the following fields in your .env.local file:

• STRIPE_SECRET_KEY=your-stripe-secret-key
• STRIPE_WEBHOOK_SECRET=your-stripe-webhook-secret
• STRIPE_PRICE_ID_ONE_CREDIT=your-stripe-price-id-one-credit
• STRIPE_PRICE_ID_THREE_CREDITS=your-stripe-price-id-three-credit
• STRIPE_PRICE_ID_FIVE_CREDITS=your-stripe-price-id-five-credit
• NEXT_PUBLIC_STRIPE_IS_ENABLED=false # set to true to enable Stripe payments

You need to do multiple things to get Stripe working:

• Get your Stripe API secret key from the Stripe Dashboard
• Create a Stripe Webhook that will point to your hosted URL. The webhook should be listening for the checkout.session.completed event. The webhook should point to your-hosted-url/stripe/subscription-webhook.
• Create a Stripe Price for each credit package you want to offer.
• Create a Stripe Pricing Table and replace the script @/components/stripe/StripeTable.tsx with your own values. It should look like this:

<stripe-pricing-table
  pricing-table-id="your-stripe-pricing-table-id"
  publishable-key="your-stripe-publishable-key"
  client-reference-id={user.id}
  customer-email={user.email}
></stripe-pricing-table>

Here are the products you need to create to get Stripe working with our example, checkout the images Here

To create them go on the Stripe dashboard, search for Product Catalog and then click on the add product button on the top right of the screen. You will need to create 3 products, one for each credit package as shown in the images before. We set them to One time payments, but you can change that if you want to and you can set the price too. After creating the products make sure to update the variables in the .env.local [your-stripe-price-id-one-credit, your-stripe-price-id-three-credit, your-stripe-price-id-five-credit] with their respective price ids, each price id is found in the product page at the bottom.

10. Start the development server:

For npm:

npm run dev

For yarn:

yarn dev

11. Visit http://localhost:3000 in your browser to see the running app.

One-Click Deploy

Default deploy using Vercel:

How To Get Good Results

The image samples used to teach the model what your face looks like are critical. Garbage in = garbage out.

• Enforce close-ups of faces and consider cropping so that the face is centered.
• Enforce images with only one person in the frame.
• Avoid accessories in samples like sunglasses and hats.
• Ensure the face is clearly visible. (For face detection, consider using tools like Cloudinary API).

If you get distorted results with multiple faces, repeated subjects, multiple limbs, etc, make sure to follow these steps and minimize the chance of this happening:

• Make sure any samples uploaded are the same 1:1 height / width aspect ratio, for example 512x512, 1024x1024, etc.
• Avoid multiple people in the samples uploaded.
• Add "double torso, totem pole" to the negative prompt when generating.
• Make sure your dimensions when generating are also 1:1 with the same height / width ratios of the samples.
