What’s the buzz?
WhatsApp just dropped a new AI chat mode called Incognito Chat. The claim? You can ask the AI anything – from movie recommendations to homework help – and Meta’s servers won’t be able to read the actual text. All the heavy lifting happens on your device using what Meta calls Private Processing.
How does it work?
Instead of sending your query to the cloud, the app runs a compressed version of a large language model (LLM) locally. The model is trimmed down to fit on a typical Android or iPhone, but it still understands context, follows instructions, and even respects the tone you set. The data never leaves your phone, so Meta says it can’t store or analyse your chat content.
Key facts
- Available now for Android 12+ and iOS 15+ in selected markets; India rollout starts next week.
- Uses on‑device inference – no internet traffic for the actual query.
- Fallback to cloud AI only for very large queries that exceed the on‑device model’s capacity.
- Privacy‑by‑design: encrypted logs, no persistent storage of the conversation.
Why Indian users should care
India is WhatsApp’s biggest market – over 530 million users. Data privacy is a hot topic after the recent Personal Data Protection Bill drafts. With Incognito Chat, users get a genuine offline AI experience, meaning no extra data collection for Meta’s ad business. For students, freelancers, and small business owners who already rely on WhatsApp for day‑to‑day communication, this could become a handy tool for quick drafts, language translation, or brainstorming without worrying about their chats being mined.
Step‑by‑step: How to enable Incognito Chat
- Open WhatsApp and tap the three‑dot menu > Settings.
- Select Chats > AI Assistant.
- Toggle Incognito Chat on.
- Choose the language model size – “Lite” for older phones, “Standard” for newer flagships.
- Start a new conversation in any chat, type
/incognitoand ask your question.
What’s the catch?
Running a LLM locally eats up CPU and battery. Early testers report a 5‑10% increase in battery drain during heavy use. Also, the on‑device model is smaller, so it may not be as knowledgeable as the cloud‑based version you get in other AI assistants. Meta still collects metadata like the fact you used Incognito – when and where – but not the actual text.
TamilTech’s take
We think this is a smart move for WhatsApp. By giving users a privacy‑first AI, Meta pushes back against the criticism that its services are data‑hungry. For Indian users, the real win is the ability to keep sensitive queries – think tax advice or personal health questions – off the cloud. However, the performance trade‑off could be a deal‑breaker for power users who expect the same answer quality they get from ChatGPT or Gemini.
What’s next?
Meta hinted at future updates that will let developers plug in custom on‑device models. If that lands, Indian startups could embed regional language models directly into WhatsApp, opening doors for vernacular AI assistance without any third‑party data leakage.
Bottom line
Incognito Chat is a welcome privacy upgrade, but it’s still early days. Give it a spin if you’re privacy‑concerned, but keep an eye on battery stats and answer quality. We’ll be testing it on a Redmi Note 12 Pro and will update you with real‑world numbers soon.
