Every Gmail timezone,
your local time.

TimeSight detects timezone references inside Gmail and converts them instantly. No tab-switching. No mental math. Works on other websites too. And this is just the beginning — more Gmail-aware timezone help is on the way.

The problem

You shouldn't need a calculator to read an email

You open three tabs just to read one time.

Someone sends “9am PST Tuesday.” You open World Time Buddy, Google, your calendar — do the math — close the tabs — and hope you didn't misread it. Every single time.

One wrong timezone. One missed call.

EST or EDT? IST in India or Israel? A single misread abbreviation and you're apologising to a client, a recruiter, or a teammate on the other side of the world. The stakes are higher than they look.

The solution

No more tabs. No more guessing.

TimeSight lives inside Gmail and handles it automatically — three ways.

Feature 01

Auto-detect & convert

TimeSight scans every Gmail email and automatically highlights timezone references with a warm glow. Click any highlighted time and an instant conversion card appears — no setup, no tab-switching, no friction.

  • Supports 30+ timezone abbreviations: EST, PST, CET, IST, JST and more
  • Handles both 12-hour and 24-hour formats
  • Spotted a wrong conversion? Report it in one tap directly from the card
Feature 02

Works beyond Gmail too

Gmail works automatically from the moment you install. Enable Universal Mode in settings and TimeSight extends to every other website — select any text with a time reference and a tooltip appears instantly.

  • Gmail works automatically — no configuration needed
  • Enable Universal Mode to extend to all other websites
  • Mismatch reporting available directly from the tooltip

Built to stay accurate

Wrong conversion?
One tap fixes it.

Every surface in TimeSight — Gmail, any website, the popup — has a built-in reporting option. If a conversion looks wrong, you can flag it instantly without leaving what you're reading. No Chrome Store reviews. No waiting. Reports go directly to us and fixes ship fast. TimeSight gets more accurate with every real-world correction.

Your report is always your choice — nothing is sent without your action.

What’s coming

Timezone clarity, inside Gmail.

Pro features are on the way: contact time profiles, reply-ready time options, and working-hours overlap when you email a group — without leaving your inbox.

Coming to Pro

Time Profiles

Builds a timezone profile per contact — passively, so you know the best time to reach out.

Coming to Pro

Reply with Times

Notices when a thread is about finding a time and drafts a timezone-safe reply with your slots — ready to copy or paste.

Coming to Pro

Compose overlap

See when typical working hours line up for everyone on To/CC — using Time Profiles — right in compose. No booking pages or calendar links; just clarity before you hit Send.

These are the first three Pro features. More are being shaped by real user research —

Early access

Pro is coming.
Get in early.

Pro Gmail timezone tools are in development. Join the list and be first to know when they launch — no commitment, no credit card.

No spam. No commitment. Just first in line.

Privacy first

Your emails stay
yours, always.

TimeSight is built on a simple principle — your email is yours. We access only what's needed, never store your content, and always tell you exactly what's happening.

No email access
Reads only what's visible on your screen to detect time references — your email content is never stored or transmitted.
Minimum access, always
We access only what's needed to convert a timezone — nothing more, nothing stored, nothing tied to you.
No account required
Install and use immediately. No sign-up, no email, no subscription needed.
You control what's shared
The only time anything is ever sent is when you explicitly submit a mismatch report — and even then, never your email content.
TimeSight

Timezone intelligence for Gmail.
And beyond.

Free to install. No sign-up, no configuration. Open Gmail and TimeSight gets to work.
