You choose the sources. Kindal reads them and writes the brief.
Complex topics come from many places: ten X accounts, two newsletters, a YouTube channel, company filings. Kindal reads all of it, every few hours, and gives you one short page when something changed, with the source next to each line. When nothing changed, you get nothing.
You add the people and publications you trust. Kindal reads everything they publish.
An X account, a newsletter, a YouTube channel, a company’s filings, a search on research or patents. Or type a topic and let Kindal propose the sources. You can change them anytime.

Brief
Something changed. You get one page: what happened, why it matters to you, what to watch.
Not a summary of everything: a brief only when there is news, sized as you want it (short or in depth, simplified or expert). Numbers and charts come only from the sources. Quiet days stay quiet.
Every line links to the post, filing or video it came from

So what, for you
Your customers buy transceivers. A SiGe crunch moves demand to 800G a quarter earlier than your roadmap assumes.
Questions
You ask a question. The answer cites the briefs and posts it comes from.
Select a sentence inside a brief and ask why. Or open the Analyst and ask across everything you follow: what changed this month, who is ahead, is this worth a post. It can draft the post from the answer.

Analyst · all your topics Reading your briefs
Who is winning in co-packaged optics this quarter, and should I post about it?
Broadcom shipped first. Nvidia’s NVL72 switch announcement moved everyone else’s timeline. Two of your sources flagged the Marvell–GlobalFoundries deal as the supply-side story. Yes, post about it: the angle is supply, not speed.
