Teti is the private AI assistant that works for you, not on you. Chat, write, research and create with powerful AI, knowing your conversations never train a model, never feed ads and are never sold. Ask anything. It stays private. WHY TETI IS DIFFERENT Most AI chat apps run on your data. Teti runs on subscriptions, so it has no reason to watch you. • Your chats never train AI models • No ads and no ad networks • No behavioral tracking or profiling • Your data is never sold • Your data stays in Europe • Delete your chats and account whenever you want ASK ANYTHING Clear answers to everyday questions, complex problems and demanding tasks. When it needs fresh information, Teti searches the web and shows its sources, so you can check every answer. DEEP RESEARCH IN MINUTES Give Teti a real question and let it dig. Deep research reads across many sources, compares them and brings back a structured answer with citations: hours of research, done in minutes. A WRITING ASSISTANT THAT SOUNDS LIKE YOU Emails, posts, reports, resumes, stories. Teti drafts, rewrites, shortens and polishes in your own tone, and translates with real context across 100+ languages. POINT YOUR CAMERA. ASK OUT LOUD. Talk to Teti with your voice, or show it what you see. Point your camera at a landmark, a plant, a menu or a label and just ask, hands-free. AI IMAGE GENERATOR AND PHOTO EDITOR Describe an image and Teti creates it. Upload a photo and edit it just by asking: a new background, a new style, a different light. AI VIDEO GENERATOR Turn a single sentence into a short video. Your prompts and results stay in your account, never in a public dataset. PDFS, FILES AND STUDY Drop in a PDF, a document or a screenshot. Teti summarizes it, pulls out the key points, reads charts and can turn any PDF into a quiz to help you study. TEMPORARY CHATS Need a conversation that leaves no trace? Start a temporary chat and nothing stays behind when you are done. SHARED PROJECTS, PRIVATE CHATS Plan a trip, a launch or a group project together. Share a project with others while your own chats stay private. MEMORY THAT STAYS YOURS Teti remembers what matters to you, so you don't have to repeat yourself. That memory lives in your account and is never used to train anything. WHAT YOU CAN DO WITH TETI • Chat about anything with a smart AI • Write and rewrite emails, posts and reports • Run deep research with sources you can verify • Summarize PDFs and turn them into quizzes • Generate images and edit photos with words • Create short AI videos from a sentence • Talk to AI with your voice and your camera • Translate across 100+ languages • Plan projects together with others PRIVACY ISN'T A FEATURE. IT'S THE FOUNDATION. We are funded by subscriptions, not by harvesting data. That is not a marketing line, it is our business model: we don't need your conversations to grow. If you pay for an AI assistant, you shouldn't also be the product. START FREE Chat with Teti, your private AI assistant, for free. Optional plans unlock more advanced features, and privacy is the same on every plan. There is no "premium privacy". Teti. Think freely.

LetUsReply AI

Some texts you fire off without thinking. Others you stare at for ten minutes. LetUsReply handles both — with replies that actually sound like you, not a robot. Paste the message you're stuck on, pick a vibe, and get replies you'd actually send. REPLIES IN YOUR VOICE Most AI gives you stiff, generic, "Happy to help!" answers. LetUsReply learns how you text — your tone, your phrasing, your habits — so every suggestion sounds like it came from you. The more you use it, the more it sounds like you. FOR THE TEXTS YOU DREAD Say a kind but firm "no" without feeling guilty Respond to a hard, emotional message with the right words Keep it professional when it counts Be funny, flirty, or chill when it's just for fun PICK THE PERFECT TONE Choose from a full range of tones — funny, serious, flirty, professional, empathetic, sarcastic, and more — or describe your own custom tone for any situation. WORKS RIGHT WHERE YOU TEXT The LetUsReply iMessage extension keeps you in the conversation: tap the paste button to pull in the message you got, then tap any reply to drop it straight into the chat — no retyping, no fiddling to send it back. Texting somewhere else? It works with any app — WhatsApp, Gmail, Instagram, and more — just copy your favorite reply and paste it in. TRAINS ON YOU Save the replies that nail it. LetUsReply learns from your favorites to sound more like you over time. Set your texting vibe, favorite phrases, and a few simple style rules, and it follows them on every reply. MORE THAN REPLIES Summarize long messages or threads before you respond Give each person their own voice — text your partner, your boss, and the group chat differently Generate several options and pick the one that sounds most like you YOUR DATA STAYS YOURS Your style profile, preferences, and favorites are stored on your device — never uploaded. Only the message you choose to reply to is sent to generate suggestions, and it's never stored. Stop overthinking what to text back. LetUsReply instead — in your voice. LetUsReply Lite & Pro LetUsReply offers optional subscriptions for more replies per day and advanced features. Subscriptions auto-renew unless canceled at least 24 hours before the end of the period; manage or cancel anytime in your App Store account settings.
