How it works

From hunch to monitored case in three steps

Seekline is a research loop, not a feed of tips. You decide what matters; the system keeps watching until the evidence says otherwise.

01

Say what you are watching

Describe a thesis, a ticker, or a half-formed question in plain language. Seekline structures it into a case with explicit assumptions — or parks it on your watchlist.

02

Seekline keeps watch

Filings, exchange announcements, and company releases are scanned on your cadence. Findings are matched to your cases by deterministic rules — no black-box ranking.

03

You make the call

Every material change arrives in your Decision Inbox with evidence attached. Approve, reject, or defer — each decision is recorded on the case timeline.

Source verification

Every number traces back to a primary disclosure.

Every record carries a source verification status: verified, conflicting, or unverifiable. Conflicts stay on the record instead of being silently smoothed over.

Watch first. Commit when the evidence does.

Research that remembers how you invest.

Every case, decision, and piece of evidence compounds into your research trail. New cases start from your prior reasoning — not from a blank page.

Common questions

Built for investors who run a process.

Is Seekline an AI stock picker?

No. Seekline helps you structure, monitor, and review your own investment reasoning. The evidence comes to you; the decision stays with you. Seekline provides research assistance, not investment advice.

What should I put on my watchlist?

Companies you care about but have not turned into a full investment case yet. Seekline watches for the signals that justify deeper research.

Can AI change my case status on its own?

No. Seekline proposes a review when evidence changes, but every major status change waits for your approval in the Decision Inbox — and each decision is recorded on the case timeline.

Where does the evidence come from?

From primary disclosures: regulatory filings, exchange announcements, and company releases. Every record carries a source verification status, so you can see what is verified, what conflicts, and what is still unverifiable.

What should Seekline watch first?

Start with a thesis, a ticker, or a half-formed question. The research loop begins there.
