Reply to any email in seconds.

1.5 billion non-native English professionals send emails every day — and most spend too long agonising over tone. ReplyRight solves that in three taps. Highlight text in Gmail, tap Share, select ReplyRight, and three complete replies are ready to copy.

The Android Share Sheet integration is the structural moat no web app can replicate. There's no context switch to a browser, no prompt engineering, no blank canvas — just paste, generate, copy, send.

Capabilities.

Share Sheet integration

Intercepts shared text from Gmail, Outlook, WhatsApp, and Slack via Android's native ACTION_SEND intent — no manual copy-paste needed.

Three reply variants

Every generation returns Formal, Friendly-Professional, and Brief replies — each calibrated for global professional context and cultural nuance.

Tone profiles

Set your industry (Tech, Finance, Healthcare, Education, General) and assertiveness level once. ReplyRight applies it to every reply automatically.

Free tier enforcement

10 free replies per day, enforced locally via Room DB and remotely via Firestore for abuse prevention — resets at midnight.

Gemini Flash 2.0 backend

Replies are generated directly on Google's infrastructure — fast, reliable, and private. No intermediate server sees your email content.

Reply history

Pro users get a searchable log of all past generated replies, stored locally in Room DB — no cloud exposure of email content.

Pricing built to convert.

Generous free tier drives daily habits. Pro and Lifetime capture two distinct buyer types at launch.

Frequently asked.

How is this different from Grammarly or ChatGPT?

Grammarly corrects grammar — it doesn't generate replies. ChatGPT requires prompt-writing skill and a browser context switch. ReplyRight is a zero-friction reply machine: paste, tap, copy. The Share Sheet means you never leave Gmail.

Is my email content stored on your servers?

No. Email text is sent directly from the device to the Gemini API and is never persisted server-side. Reply history is stored locally in Room DB on the device only. See our privacy policy for full details.

What languages are supported?

English at launch. Hindi, Spanish, and Portuguese UI localization ships in Month 2–3. Gemini Flash natively generates replies in all three languages when the user preference is set.

Why Android only at launch?

The Share Sheet integration is the core moat, and it's significantly more powerful on Android. An iOS port (SwiftUI + Share Extension) is planned once Android proves $3K+ MRR.
