GRP MarketLens
Three AIs research the market, debate, and show you what to watch.
Right now it's an internal tool we use ourselves while we test and refine it.
A home page for GRP MarketLens is on the way. Questions in the meantime? Email [email protected].
Actively being worked on. We're building this right now. Features and details on this page may change as we go.
The problem, and how GRP MarketLens helps
The problem
There's too much market news to keep up with, and it's hard to know which stocks deserve a closer look. Asking a single AI gives you one confident-sounding opinion with no way to tell how solid it is.
The solution
GRP MarketLens gives the same research task to Claude, Gemini and ChatGPT. Each picks stocks on its own, with sources. Then they challenge each other's picks, and you see exactly where they agree, where they split, and why.
What GRP MarketLens does
Three AIs, one task
Claude, Gemini and ChatGPT each research recent news separately, with identical instructions for a fair comparison.
A built-in debate
Each AI reads the others' picks and explains why it agrees, disagrees or changes its mind.
Ranked by agreement
Picks all three flag rise to the top, and splits like “2 BUY · 1 HOLD” are shown openly.
“What would prove me wrong”
Every pick names a specific event that would show the idea was wrong, so you know what to watch.
Source quality you can see
Each pick lists its sources, rated by type, and picks backed only by weak sources are flagged.
The agent house
A dollhouse on the home screen shows what the AIs are up to: researching, debating, or resting between runs.
Three steps
Three AIs separately scan the last few days of news and pick stocks worth watching, each backed by sources.
They swap notes and debate, explaining why they agree, push back or change their minds.
You get a plain-language summary of where they landed, and can accept it or send them back for another round.
Common questions
Does it tell me what to buy?
No. It shows what three AIs think is worth watching and why, including where they disagree. Decisions are yours.
Why three AIs instead of one?
When three different AIs land on the same idea for different reasons, that's a stronger signal. When they disagree, that's worth knowing too.
How do I know the AIs aren't making things up?
Every pick needs at least two dated sources, sources are rated by quality, and each pick says what would prove it wrong.
Does it actually work?
We don't know yet. Picks are tracked against the S&P 500 with no after-the-fact edits, so results can be judged honestly over time.
