Prefera shows you which AI answers name your brand and which name a competitor instead. It helps you fix the gap and then checks whether the fix worked.

It asks the buyer questions you care about to AI engines such as ChatGPT, Google AI Overviews, Google AI Mode, Gemini, Perplexity and Claude. It saves every answer with the pages the engine cited.

## The loop

Prefera works as one loop. Each step has its own screens in the sidebar.

| Step | What it means | Where in the app |
| --- | --- | --- |
| Track | Ask your questions on the engines on a schedule and save the answers. | **AI answers**, **Google rankings**, **Competitors** |
| Find | See where you lose and which moves are worth your time. | **Opportunities**, **Authority** |
| Fix | Plan and write content from facts you approved, then publish it. | **Content plan**, **Fixes** (with the **Create** button), **Facts** |
| Prove | Re-check the questions a fix targeted and compare them with untouched control questions. | **Results**, **Proof** |

**Home** (**This week**) sits on top. It shows three numbers you can check, your best moves for the week and the pages that moved.

## Who it is for

Prefera is for people who want to be named when a buyer asks an AI engine for a recommendation: founders, marketers and agencies. An agency can run several brands from one workspace (**All brands**).

## People and agents

- People use Prefera in the app at `/app`.
- Agents use it over MCP or the REST API. See [Connect an agent (MCP)](/docs/agents) and [REST API](/docs/api). Keys and connections are in **API & MCP** in the sidebar.

## For agents reading these docs

- `/llms.txt` lists the docs pages for language models.
- Every page has a Markdown version at `/docs/<slug>.md`. For example, this page is `/docs.md` and the Quickstart is `/docs/quickstart.md`.

## Where to start

1. Follow the [Quickstart](/docs/quickstart) to sign up, set up your brand and start the first run.
2. Learn how [questions, answers and engines](/docs/concepts/tracking) work.
3. Approve your [facts](/docs/concepts/facts) so drafts can only state what is true.
4. Read how [Proof](/docs/concepts/proof) decides whether a fix worked.
5. See [Plans, add-ons and billing](/docs/account/plans) for what each plan includes.
