## What is Teti?

Meet Teti. An AI assistant built around a simple idea: what you think, write, and ask should stay yours. Teti helps you write, research, create, and work through complex problems — without ever turning your conversations into training data for someone else.

A DIFFERENT KIND OF AI
Most AI assistants live on your data. Teti lives on your subscription.
That single difference changes everything. No tracking. No profiling. No "improving the model" with your private thoughts. You pay for the service, and the service works for you — not the other way around.

WRITING THAT SOUNDS LIKE YOU
From a half-formed idea to a finished piece. Teti drafts, sharpens, and rewrites with you — social posts, emails, long reports, creative writing. It learns your tone over time and helps it come through more clearly, without that tone ever leaving your account.

RESEARCH WITHOUT THE NOISE
Ask the questions that actually matter to you. Teti searches the web, cross-checks sources, and brings back what's useful — with citations you can verify. From early curiosity to deeper analysis, your line of thought stays your own.

WORK WITH IMAGES, DOCUMENTS, FILES
Drop in a photo, a PDF, a screenshot. Teti reads charts, summarizes documents, extracts text, and explains what it's looking at. Useful for research, study, work — and private, every step of the way.

GENERATE IMAGES AND VIDEOS
Describe what you want. Teti creates it — images and short videos from plain language. Your prompts and outputs stay in your account, not in a public dataset.

THINK OUT LOUD
Speak instead of typing. Use Teti as a voice assistant to brainstorm, draft, or work through ideas on the move. Dictation works across many languages, and what you say goes to Teti — and nowhere else.

WHAT YOU CAN DO WITH TETI
▶ Refine writing across tone, structure, and clarity
▶ Process meeting notes and pull out what matters
▶ Build reports and marketing content step by step
▶ Reason through complex problems out loud
▶ Plan projects and organize messy thinking
▶ Translate across 100+ languages with real context
▶ Analyze PDFs, screenshots, and visual content
▶ Generate images and videos from text
▶ Work hands-free with voice dictation

PRIVACY ISN'T A FEATURE. IT'S THE FOUNDATION.
Teti is built so that your conversations can't be used against you, sold, or learned from.
— No training on your chats
— No behavioral tracking
— No advertising networks
— No data resale
— Full deletion, anytime
We're funded by subscriptions, not by harvesting your data. That's not a marketing line — it's our business model. We don't need your conversations to grow.

A QUIETER WAY TO USE AI
No ads. No surveillance. No second life for your data inside someone else's model. Teti is the AI assistant for people who want the full power of modern AI without the trade-off that comes with it.

TRY TETI FREE
Start chatting for free. Optional plans unlock more advanced capabilities. Privacy works the same on every plan — there's no "premium privacy."
