YOUR DATA AND AI

Know what Tayan reads
and where AI runs.

Database access, answer sources and AI processing each have a role in how you use Tayan.

Read-only database access

Can Tayan change my data?

Queries are checked before they run. Connect with a read-only database account to limit access to existing records.

What is the answer based on?

Open the SQL used for a calculation or the document passages cited in an answer. Check the assumptions and source context before acting on a result.

Where does AI processing happen?

The web experience uses cloud AI. In desktop local mode, AI requests stay on your device without automatically switching to the cloud. Remote databases still need their own network connection.

FREQUENTLY ASKED QUESTIONS

A few things
before you begin.

What is Tayan, exactly?

Tayan helps you explore databases and documents through conversation. Ask a question, review the result and follow up to explore further. You can inspect the calculation or source passages behind an answer.

Do I need to know SQL?

No. Ask in plain English and Tayan prepares the query for you. SQL is available if you want to inspect the calculation. You should still check that the result answers your question and that its assumptions make sense before using it to make a decision.

Which databases does Tayan work with?

Tayan includes desktop connectors for BigQuery, MariaDB, MySQL, PostgreSQL, Snowflake, SQL Server and SQLite. Choose a database connection and use an account with read-only permissions to explore its data.

Which document formats can I use?

The desktop version supports text-based PDFs, TXT and Markdown files. Answers link to the passages used. Scanned PDFs need text recognition (OCR) before import. If the source material does not contain enough information, Tayan says so.

Can Tayan change my database?

Tayan is designed for read-only analysis. Queries are checked before they run, and you should connect with a database account that has read-only permissions. This keeps access limited to reading existing records.

Can I use a local AI model?

Yes, in the desktop version. Supported models run through llama.cpp or Ollama. In local mode, AI requests stay on your device and do not automatically switch to cloud processing. Remote databases may still need a network or VPN connection. The web experience uses cloud AI.
