An AI for your wellbeing. Not therapy.
An AI emotional wellbeing app, in English, Hindi or Hinglish. If you are ever in danger, real people are one tap away.SATHI is an AI emotional wellbeing app: a private chat that helps you talk through hard days, in English, Hindi or Hinglish. It listens, it doesn't judge, and it never diagnoses. SATHI is an AI, not a person, and if you are ever in danger it puts real people one tap away.
Beta for adults in India. You can start without signing in. Pricing
Some nights the hardest part is finding the words. SATHI is a quiet light that helps you say it, in your words, at your pace, and knows when a real person should be the one to answer.
How SATHI listens
Nothing clever is hidden. This is what happens between you pressing send and SATHI's first word.
Type in any language or mix. SATHI reads how you seem in this message: raw, anxious, venting, joking, hopeful. It reads it fresh every time.
A multilingual phrase list and an AI classifier look at the message in context. If you may be in danger, real people's numbers come before anything else.
Word by word, in your language and your register, with one question at most. In a crisis there is no AI text at all: one human-written line and the numbers.
What SATHI does
Say as much or as little as you like. Replies stream in word by word and follow your tone, not a script.
work has been really heavy this week
Heavy in the piling-up way, or heavy in the slow, grinding way where even small things cost something?
the second one honestly
That kind wears you down quietly. What has been asking the most of you?
Write the way you speak. SATHI replies in the same language and script, slang and all. Tap a language.
I don't feel like myself lately
Not like yourself in a flat, far-away way, or restless and on edge?
No name or phone number needed. Encrypted before it is stored, in Mumbai.
One conversation, your profile, or everything. Immediate and permanent.
Tele-MANAS and 112 from every main screen, including chat. Works offline.
SATHI breathes, blinks and glances with you. Press and hold it and it breathes with you.
A calm sage paper by day, deep ink by night. It follows your phone, or your choice. Tap to switch.
Write in any of these. English, Hindi, Hinglish and Spanish are safety-tested; other languages are translated for the safety check first.
Safety promise
These lines are free, confidential and open to everyone in India. SATHI cannot call for you; you make the call, and the numbers are always one tap away.
Every message is checked before SATHI replies. A message that may mean danger, to you or to someone else, gets one fixed, human-written line in your language and the numbers above, at once, with no animation and no waiting for the AI. For a medical emergency, 112 comes first.
Get support stays pinned in the header for the rest of that conversation. If you say you were joking, SATHI does not argue and the card stays. Under-18 disclosures get a kind stop with support lines, and the conversation is deleted.
Privacy in plain words
The short version of the Privacy Notice, in the same words.

Questions
No. SATHI is an AI emotional wellbeing app. It says it is an AI before you start, in every conversation, and whenever you ask, and it is not a replacement for a therapist or a doctor. It is a private place to think out loud, and a quick route to real people when it matters.
Every message passes a multilingual phrase list and an AI safety check. If you may be in danger, SATHI shows one fixed, human-written line and India's crisis lines at once (Tele-MANAS 14416 and 1-800-891-4416, Emergency 112), with 112 first for a medical emergency. Get support stays pinned for the rest of that conversation. SATHI cannot call anyone for you.
You, and during the beta our AI providers. Everything is encrypted before it is stored and only the running app holds the key. Nobody on the SATHI team reads conversations unless you opt in to de-identified research review. Google Gemini and Groq process messages to write replies, and on Gemini's free tier Google may use what you send and human reviewers may read it; see the Privacy Notice for exactly what that means.
Replies come from Google Gemini (free tier: Google may use content to improve its products and human reviewers may read it) or, when Gemini is busy, from Groq (which does not retain prompts by default). The safety check runs on Groq first, then Gemini. The crisis line itself is never written by an AI.
You can start and use Help Now without signing in. SATHI Plus needs Google sign-in (a Gmail address). No phone number. SATHI asks for your year of birth, because it is for adults 18 and over, and for your consent.
This is a closed beta. The APK installs directly from sathi.world; Android asks once to allow installs from your browser. On iPhone, SATHI runs as the same app in Safari and can be added to your Home Screen.
The crisis lines, the safety wording and the legal checks are done for India first. From outside India the app shows a not-available screen with a worldwide helpline directory.
It can be. The beta runs on free AI tiers, so at peak a reply may take longer or SATHI may say it could not reply just now, with Try again. The crisis path never depends on the AI.
Yes, in About me: Delete everything removes your account, profile, conversations and counters immediately and permanently, and takes you back to the start.
SATHI is free while SATHI Plus opens, and nobody is charged. When it opens, your first 12 hours are free and SATHI Plus is Rs 199 a month (founding offer: Rs 99 for the first month). Prices are in Indian rupees and include any taxes. Help Now and crisis support are always free. Cancel any time and keep access to the end of the month; if you ask within 7 days of any charge, we refund it in full.
Not yet. We are arranging an independent clinical review of how SATHI responds in difficult moments, and the Safety page will say when it has happened. The crisis reply is a fixed line written by our team; our latest safety test results are on the Safety testing page.
