# What ThothII does

ThothII helps turn a natural-language question into reviewed SQL. It is intended for
people who know the meaning of their data and need to make the assumptions behind a
query explicit. The model proposes; a human reviewer approves, corrects or rejects.

## From a question to a reusable result

The [eight-phase workflow](skills.md) clarifies the question, consults reusable knowledge,
selects relevant Evidence and database objects, prepares a query plan, and produces SQL
for review. Approved knowledge can be saved for later questions.

- **Workspace:** the domain context and its Evidence configuration.
- **Database catalog:** tables, columns, relationships and reviewed descriptions.
- **Evidence:** domain sources and rules with provenance that a reviewer can inspect.
- **Memory:** reusable clarifications, SQL rules, solved questions and explained errors.
- **Session:** the saved artifacts and decisions for one question, not a permanent chat transcript.

Resuming a session uses its saved state. Model output is a proposal, not a guarantee of
correctness: review the scope, assumptions, sources and SQL before relying on the result.

## What an installation includes

The Docker stack includes the web application, its runtime, a PostgreSQL metadata/Memory
catalog, Qdrant and the embedding service. A browser is the normal user interface; the
host `tht` command is used to configure and operate the installation.

The data warehouse and generative model endpoints are configured separately. Docker
does not supply their credentials, network access or domain data. A standalone installation
is therefore self-hosted, but is not automatically offline or independent of those services.
Review data-access permissions and the model-provider configuration before using real data.

## Choose your next step

- Install on Mac, Windows through WSL2, or Linux: [Italian](install/standalone-manual-it.md)
  or [English](install/standalone-manual-en.md) manual procedure.
- Configure [display mode and language](install/shell-and-language.md),
  [authentication](install/authentication-local.md) and [models](general/pi-configuration.md).
- Prepare [workspaces](operations/workspaces.md) and [databases](operations/database-management.md).
- Start a reviewed question using the [user guide](guida-utente.md).

The installation guides state the platform tests still to complete. Availability of a
procedure is not a certification that every target machine has been tested.
