Less checking. Better timing.

The web changes constantly.
Your inbox shouldn’t.

Tell Me When separates changes that matter from everything else.

01

Say it normally

Describe the result you care about in plain language—stock, price, openings, deadlines, or status.

02

Skip the noise

Hashes and lightweight comparison remove unchanged pages and trivial edits before AI is called.

03

Get one clear alert

We email only after a clear match and suppress repeat notifications for the same transition.

How it works

Three steps. Then close the tab.

  1. 1
    Paste a public URL

    Choose a page that works without an account or JavaScript rendering.

  2. 2
    Describe the moment

    Be specific about the state, phrase, year, or price you are waiting for.

  3. 3
    Let us keep watch

    The first check sets a baseline. Later meaningful changes are judged conservatively.

FAQ

Good questions, answered.

What kinds of pages can I watch?

Any public webpage that can be read without signing in and does not require JavaScript to show its main content.

Will the first check send an alert?

No. The first successful check saves a baseline. Alerts can only happen after a later meaningful change.

How often are pages checked?

The private preview checks once a day. You can also run a safe manual check from your dashboard.

How does Tell Me When avoid noisy alerts?

Exact and insignificant changes are filtered before AI is used. Ambiguous AI judgments do not trigger an email.

Why is the paid plan not priced yet?

We are validating real monitoring costs and useful limits before fixing a price. The current private preview remains free.
