Why This Exists

Your AI Shouldn't
Spy On You.

01
They charge $20/month

ChatGPT Plus costs $240/year. Your resume, medical questions, financial details โ€” all sent to cloud servers, stored, and used to train their models. You rent access to your own conversations.

02
We charge $4.99 once

All AI processing happens on your phone's CPU. No servers. No transmission. No analytics. Your words never leave your device. Own it forever โ€” even if we disappear.

03
Pay once, own forever

No $20/month subscription. No free tier with upsells. $4.99 one time. Works forever. Works offline. Works even if the company disappears.

The Founder

Suraj
Kumar.

What if your AI assistant didn't need the internet? What if your resume, your medical report, your private thoughts never left your phone? That's what Promptforge Labs builds.

I'm a solo developer building AI-native Android apps with one rule: your data stays on your device. Not locked behind subscriptions. Not harvesting your data. Not cloud-dependent. AI that belongs to you โ€” running silently, serving only you, on the device in your hand.

I build in my free time. Every app is a deliberate experiment in what's possible when one person with the right tools decides to start a small revolution.

Based in India. Building for the world.

What This Means
Hypertension stage 2 means your blood pressure is consistently at 140/90+. Your heart works harder than it should.

Lisinopril is an ACE inhibitor โ€” relaxes blood vessels so blood flows more easily.
Questions for Your Doctor
1 What blood pressure should I aim for?
2 Foods to avoid with lisinopril?
3 How often to monitor at home?
Not medical advice. Always consult your doctor.

Vision

Where This
Is Going.

01
Privacy as Default

Every product I build treats privacy as a first-class feature, not an afterthought. On-device AI is the future โ€” your data stays with you, always. No exceptions.

02
AI for Everyone

Not just for enterprise. Not just for developers. AI that a student, a creator, a small business owner can pick up and immediately use to change their life.

03
The Forge Expands

More apps. More tools. More platforms. Promptforge Labs is a growing ecosystem of AI-native products โ€” all tied by one philosophy: power to the individual.
