What We Shipped: Price-Range Intervals, Item Pages, a 4D Market Map, and an AI Coach

We've added a handful of new surfaces to Grand Flip Out over the last few weeks. This is a plain tour of what they are, who they're for, and how to actually use them. No hype — just what changed and where to click.

The short version: the dashboard now gives you a price range you can trust instead of a single guessed number, every item has its own intelligence page, you can watch the whole market move in 3D, there's a live view of what's pumping and dumping, and there's a free AI coach that answers flipping questions in plain English. All of the core is free.

1. Price-range intervals (not a single guessed price)

Most tools show you one number — "this is worth 1,240 gp" — and leave you to guess how much to trust it. We think that's the wrong shape. A price is a range, and the honest thing is to show the range.

Every item now carries a buy/sell interval: a likely low and a likely high, rather than a single point. These are conformal-calibrated, which is a statistical method with one useful property — it's tested against real outcomes every day and tuned to hit 90% coverage. "90% coverage" means: when we say the price will land inside the range, it actually does about 9 times out of 10. It's a measured guarantee, not a vibe.

One honest note: a band is only as good as its calibration, and calibration is data-hungry. Liquid, frequently-traded items get tight, reliable bands. Thin, rarely-traded items get wider bands — because we genuinely know less about them, and we'd rather show that than fake a precise number.

2. Item pages — every item gets its own intelligence view

Each item now has a clean URL at /item/<id> — for example the Abyssal whip page. It pulls together everything we know about that one item in a single place:

• The current buy/sell prices and the calibrated price range
• Its market regime right now — pumping, dumping, recovering, or stable
• Recent price history and volume
• Dump signals and, where we have it, a recovery estimate

It's the page to open when you're about to commit gold to a specific item and want the full picture before you click buy. Every item name across the site — including the new regimes view below — links straight to it.

3. The 4D market map

The 4D market map shows the entire Grand Exchange as a cloud of bubbles. Every bubble is an item, and its position encodes the three things that matter for a flip:

• How expensive it is (the X axis)
• How much it trades (the Y axis)
• How fat the margin is (the Z axis)

The colour is the market regime — green for pumping, red for dumping, gold for recovering, blue for stable — and a bubble gets bigger when an item is unusually volatile. The "4th dimension" is time: press play and the whole market animates through recent snapshots, so you can literally watch regimes shift.

It's best on a desktop where you can rotate and zoom. On a phone you can still spin the cloud, but the full experience wants a bigger screen.

4. A live regimes view

The newest surface is the live regimes page. It answers one question fast: what's moving right now?

It sorts the live market into three buckets — pumping (prices drifting or surging up), dumping (sustained selling pressure pulling the price down), and recovering (bouncing back after a dump) — and lists the items in each, refreshing automatically. The colours match the 4D map so the whole site speaks the same visual language. Tap any item to jump to its full intelligence page.

Under the hood it's the same CUSUM regime detector we wrote about in how we detect GE dumps — computed over the full market history, not just a 5-minute snapshot. It's a shareable link, so if you spot a wild dump you can send the page to a friend and they'll see the same live state you do.

5. An AI flipping coach

Finally, there's the GFO Coach — a chat assistant that answers OSRS flipping questions in plain English. Ask it "is it worth flipping nature runes today?" or "what's dumping right now and might recover?" and it answers using live market data and the OSRS Wiki, with citations so you can check its sources.

It's grounded in the same intelligence engine that powers the rest of the site, so it isn't making things up from thin air — it's reading the live numbers and explaining them. The coach is free to use, with a generous daily message allowance.

What's free, and what's Pro

We'll keep saying this because it's the actual plan: the core is free, forever. Everything above — the price-range intervals, item pages, the 4D map, the live regimes view, and the AI coach — is free to use. Pro is an optional $4.99/mo (with a 7-day free trial, cancel anytime) that adds speed and a head start, not a wall around the basics.

The one-line summary: free users see the same intelligence; Pro users see it faster and first, plus a few power-user tools. We won't cripple free features to push Pro — the free tier is the product, and the data depth is the edge.

That's the tour. If you want the methodology behind the regime detection, the dump detection write-up goes deep on the math. Otherwise, the fastest way to get a feel for any of this is to open a page and click around. It's all free.
