A macOS menu-bar price checker for Path of Exile 2 and Path of Exile 1 that works while you play through GeForce NOW.
Overlays like Awakened PoE Trade and Exiled Exchange 2 read the item text from the clipboard. Under GeForce NOW the game runs on NVIDIA's cloud PC, so that clipboard never reaches your Mac. PoEPriceCheck reads the tooltip off your screen with Apple's Vision OCR instead. Hover an item, press ⌃D, and a small panel shows the price next to the cursor.

- Currency, fragments, runes, essences, omens, ritual items, uniques: priced from poe.ninja (cached for 15 minutes), with the stack total.
- Rares and magic items: priced with a fuzzy search on the official trade site, because searching
every exact stat usually finds nothing. The search:
- uses only the stats that drive value (skill levels, movement speed, spirit, life, resistances, crit, cast/attack speed, DPS, defences…) and skips filler mods
- folds related mods into pseudo totals: total life, total elemental resistance, attributes
- searches minimums only, a margin below each roll (default 10%), with no maximums
- replaces local defence and damage mods with the item's Armour/Evasion/ES or DPS
- relaxes automatically below 10 results (drops the item-level floor, widens the margin, then drops the least important stat) and shows what it changed
- lets you tick/untick stats and change the margin in the panel, then Search again, or Open on trade site
- Unidentified items: priced by base type and unidentified tier.
- PoE 1 or PoE 2, detected automatically: with menu › Game › Auto (the default) each check works out which game the tooltip is from: the league in the area overlay, the window title if it names the game, PoE 2's item class line and "Requires:" wording, and which game's data knows the item. Items both games have (Divine Orb) keep the last game. The panel footer shows the game; hover it for the reason. You can also fix the game to PoE 1 or PoE 2 in the same menu. PoE 1 uses poe.ninja's PoE 1 prices (shown in chaos and divine) and the PoE 1 trade site. OCR can't see sockets, so for body armours and two-handed weapons the panel has a Links control (Any / 5L / 6L) that picks the 5L/6L poe.ninja price or adds a links filter to the trade search. PoE 1 tooltips show no item level unless you hold Alt, so PoE 1 searches don't filter on item level.
- League: read from the in-game area overlay when it's on screen (e.g. "Forbidden Rites League"); otherwise poe.ninja's current league, or pick one from the menu.
- Respects GGG's
X-Rate-Limit-*headers.
It is read-only: it captures the screen and calls public price APIs. It never sends keystrokes or clicks to the game.
- A listen-only keyboard tap (plus a regular global hotkey) sees ⌃D even when GeForce NOW or Chrome has grabbed the keyboard in fullscreen.
- ScreenCaptureKit grabs the display. Vision OCRs it in about 0.2 s on Apple Silicon.
- The tooltip is found as the stack of centre-aligned text lines on a near-black panel. Stash tab labels, the right-aligned map overlay and world text are rejected. Text colour, normalised for brightness so dimmed tooltips still work, gives the rarity and mod types.
- Lines are matched to trade stat IDs with fuzzy matching against the trade site's stat templates, which tolerates OCR typos.
- If a frame looks smeared by video compression, it re-captures once.
Get PoEPriceCheck-<version>-macOS.zip from the latest release
(macOS 14+, universal binary), unzip it and move PoEPriceCheck.app to Applications. The app isn't
notarized, so on first launch right-click it › Open › Open. Then grant the two permissions listed under
Install below.
To build it yourself instead: macOS 14+ on Apple Silicon (built and tested on an M4 at 3840×2160), Xcode 15+ / Swift 5.10+.
git clone https://github.com/FuzzySideUp/PoEPriceCheck.gitcd PoEPriceCheck && scripts/build_app.shopen ~/Applications/PoEPriceCheck.appThe build script signs with your Apple Development certificate if you have one. That keeps the permissions below across rebuilds; with ad-hoc signing macOS may ask again after each rebuild.
Grant two permissions when prompted (System Settings › Privacy & Security), then quit and reopen the app:
- Screen & System Audio Recording: to read the tooltip
- Input Monitoring: so ⌃D works while GeForce NOW holds the keyboard in fullscreen
The dollar-sign menu-bar icon has the hotkey, league, default margin, listing status, panel size, and "Save captures" for debugging.

Early. Tested on one 4K display at 1× scaling. Other resolutions should work, but the detection thresholds were tuned on 4K captures. PoE 2 is the most tested; PoE 1 support is new.
