Getting started with Terasu Signal

Terasu Signal shows you when, by whom, and how far your sales documents are read. You can reach out while interest is still high, instead of following up blind.

This article walks through sharing your first document and reading the response.

No sign-up required to try it

You can add up to 3 PDFs and create share links without a Terasu account.

Share in three steps

Recipients need no account and no special app. The document opens in their browser.

What you learn after sending

Once the recipient opens the link, the reading state appears in your document list. There are four stages.

Revisited is the strongest signal: the deal is moving, and the document may be circulating internally. It is usually the best moment to make contact.

Time spent per page is recorded too, so you can see where attention actually went — for example, a long pause on the pricing page.

Get notified when it is read

After signing up for free, you receive view notifications by email — and in Slack if your workspace is connected.

You choose which moments notify you: Opened, Half read, Fully read, Revisit, and High interest signal. Opened and High interest signal are enabled by default.

See When notifications do not arrive to configure them.
