Most AI waits for you to ask
A chatbot answers when you think to ask, and by then the news is old and the price has moved. Tellwhen works the other way round. Tell it once what matters, and it speaks first.
The same news. One of them reached you on Tuesday.
One email sets it up
Say what you want to hear about. You get a reply listing your alerts, then an email whenever one of them happens. Reply in plain words to change anything.

Watch for anything
If you can say it in a sentence, you can get an email when it happens.
Know what moves your stocks
Name the companies you hold and what would change your mind: a deal falling through, a lost customer, new guidance. You hear it from us, not from a red number in your portfolio.

Never miss a paper in your field
Describe the problem you work on, not just keywords. New papers and conference news are read against what you said matters.

Follow funding rounds above your bar
Set the line in your own words, like over $100M. Smaller rounds, rumors and old news never reach you.

Hear about openings at the companies you want
Name the companies and the kind of role. When a new one is posted, you'll know.

Anything you can put in a sentence
A price, a page, a paper, a filing, a launch, a new role, a ticket sale. Say what you're waiting for, and we'll keep watch.
We read over a hundred newsrooms, regulators and research feeds, and search the web for each alert.
Hi, I'm Zanwen
I buy stocks, but I don't have time to follow the news every day.
Last year I spotted a company early, then missed its IPO. This year bad news hit it. I missed that too, and didn't sell in time.
So I built Tellwhen. Tell it what matters to you, and you won't miss it again.
