# Start Here

This documentation covers the Haut.AI SaaS Platform: how to create and brand a [Consumer App](/haut.ai/haut.ai-features/consumer-apps.md), configure [algorithms](/haut.ai/haut.ai-features/algorithms.md) and product recommendations, and integrate the platform through the API. For company and product information, see [haut.ai](https://haut.ai).

These docs are for the people who run Haut.AI inside a business — product and marketing teams setting up an app, data and research teams working with results, and developers integrating the API. The sections below tell you which part of the tree answers which question, so you can go straight there.

## What's in these docs

The sidebar is grouped into seven sections. Each one answers a different kind of question.

### Quick Start Guides

End-to-end paths from an empty account to a working app. Two starting points, depending on how much you want to build yourself:

* [No-Code App for e-Commerce Businesses](/haut.ai/quick-start-guides/no-code-app-for-e-commerce-businesses.md) — import your product catalog, create and brand a Consumer App, embed it on your site, and connect Klaviyo for follow-up email.
* [Build Custom App powered by Haut.AI](/haut.ai/quick-start-guides/build-custom-app-powered-by-haut.ai.md) — wire your own backend to the API, send images for analysis, pull recommendations, and handle end-user data.

Start here if you are new to the platform. Both paths are ordered, so follow them top to bottom.

### Guides

Longer walkthroughs for one business outcome, built from several features at once.

* [Consumer App for Clinics: From Setup to Follow-Up](/haut.ai/guides/lead-generation-for-clinics.md) — set up a Consumer App as a lead funnel for a clinic or medspa, capture visitor details, and route them to your CRM.

### Haut.AI Features

The reference section for everything in the SaaS dashboard. Come here when you know the feature name and need the detail.

* [Consumer Apps](/haut.ai/haut.ai-features/consumer-apps.md) — creating apps, iFrame embedding, surveys, advanced settings, Google Analytics, and webhooks.
* [Algorithms](/haut.ai/haut.ai-features/algorithms.md) — what each metric measures, how results are scored, and how Face Metrics 2.0, Face Skin Analysis 3.0, hair, and body metrics differ. Read [Algorithm Results](/haut.ai/haut.ai-features/algorithms/algorithm-results.md) first if you are interpreting scores.
* [Product Recommendation System 2.0](/haut.ai/haut.ai-features/product-recommendation-system-2.0.md) — product inventory, shelves, product and user tags, and the matching algorithm. Version 1.0 is [deprecated](/haut.ai/haut.ai-features/product-recommendation-system-1.0-deprecated.md).
* [SkinGPT Overview](/haut.ai/haut.ai-features/skingpt.md) — simulated skin-care outcomes: models, effects, levels, and simulation parameters.
* [Skin.Chat Overview](/haut.ai/haut.ai-features/skin.chat.md) — the conversational assistant: integrations, website and React Native setup, and the data it collects.
* [LIQA](/haut.ai/haut.ai-features/liqa.md) — the image-capture component that checks selfie quality before analysis.
* [Datasets](/haut.ai/haut.ai-features/datasets.md) — how images, subjects, and results are stored, plus [Analytics](/haut.ai/haut.ai-features/datasets/analytics.md), CSV export, PDF reports, and anonymization.
* [Studies](/haut.ai/haut.ai-features/studies.md) — set up a study, launch it, and export the results.
* [Upload Images](/haut.ai/haut.ai-features/upload-photos.md) — the upload interfaces in the dashboard, including Smart Uploader.

### Administration

Account-level settings: [sign-in and authentication](/haut.ai/administration/login-and-authentication.md), OIDC SSO, passkeys, and switching between accounts.

### For Developers

API documentation for integrating the platform.

* [Authentication and Token Management](/haut.ai/developers/authentication-and-token-management.md) — API keys, tokens, and how to keep them valid.
* [SaaS API Overview](/haut.ai/developers/saas-api-overview.md) — endpoints grouped by area, with the result scheme for every algorithm.
* [Pagination](/haut.ai/developers/pagination.md) and [Errors](/haut.ai/developers/errors.md) — conventions that apply to every endpoint.
* [API Breaking and Non-breaking Changes Guide](/haut.ai/developers/api-breaking-and-non-breaking-changes-guide.md) — what we may change without notice, and what we will not.

The live specification is at <https://saas.haut.ai/api/swagger/>.

### Legal

[Data protection and compliance](/haut.ai/legal/legal.md), the [service license agreement](/haut.ai/legal/service-license-agreement-sla-and-maintenance.md), and [support](/haut.ai/legal/support.md) channels and response times.

### Release Notes

The [Changelog](/haut.ai/releases/changelog.md) lists platform changes by version, newest first. Check it before you report something as broken — the behavior may have changed on purpose.
