See every signal behind every price.
Cardpulse.ai is an agentic pricing layer for card collectors and shops. Live comparables, sentiment-aware forecasts, and a one-click scout that scours the web to tell you whether a card is moving — before the market figures it out.
Front. Flip. Back. Next card.
Hold a card in front of your iPhone — Cardpulse's edge detector picks up the rectangle, waits a beat for steadiness, and auto-captures the front. Flip the card; the camera re-arms, grabs the back. Move on. Capture a stack of fifty in a few minutes without tapping a button.
When you're done, hit Match all. Every captured pair runs through Claude vision and the catalog matcher in parallel — slabs, raws, parallels, TCG, comics — and lands in your inventory with the right variant pre-selected.

A slab cert? Done. A Charizard? Already cataloged.
Cardpulse cascades through canonical card databases on every scan. PSA cert numbers resolve to the exact specimen. Magic cards through Scryfall, Pokémon through pokemontcg.io, Marvel issues through ComicVine — all with confidence scores so the UI can badge how it knows.
When the catalog hasn't seen a card before but an authoritative source nailed the identity, Cardpulse materializes the row on the spot — clean image, set code, rarity, all tagged with provenance. No more contribute-form limbo for every TCG card.
Cascade order: PSA cert → Scryfall / pokemontcg / ComicVine → trigram catalog → eBay listings

Every comparable, every source, on one screen.
Search any card across sports, Marvel, and the four big TCGs. The catalog pulls live comps from eBay, PriceCharting, and a growing list of marketplaces — and shows you where every price comes from, so a $4,500 listing never gets confused with a $3,000 sale.
A real 80% confidence interval (computed on actual ticks, not a ±8% guess) tells you when a price is solid versus speculative.

Buy. Hold. Sell. With the receipt.
Every variant gets a 30-day and 90-day forecast with an 80% prediction band. Conviction (Buy / Hold / Sell) is derived from your card's price history plus recent sentiment, then handed to a Claude reviewer with the actual signal text — and the permission to downgrade Buy or Sell to Hold when the evidence is thin. Single ESPN injury squibs don't flip a vintage star to Sell anymore.
Because the reasoning is auditable — Bayesian shrinkage on signal mass, severity-calibrated sentiment, and the reviewer's rationale shown verbatim — you stop trusting a black box and start trusting your own judgement again.

Watch the data flow in real time.
On every card you can open the live pipeline view: Sources → Signals → Agent → Output. Particle sparks travel left-to-right along each connection, colored oxblood for bullish and graphite for bearish, so you can see at a glance which direction the market's pulling.
Click any node to inspect: the article that started it, the sentiment the agent extracted, the forecast that came out the other end. No black box, ever.
Renders as an interactive tab in the card detail panel
One click. Fresh signals. Updated forecast.
On any card detail, hit the Scout button. The agent runs a Reddit-wide search for the player's name (or the card's subject for TCG and Marvel), reads each fresh post, scores the sentiment, and re-runs the forecast — all in about 10 seconds.
The receipt tells you how many new signals landed and how the conviction shifted. If a card just got hot — or just got cold — you'll know in one click instead of three browser tabs.

Tell the agent what just happened. Watch the forecast move.
Saw a player drop 50? Hear about a trade before the news cycle catches up? Type it in. The agent classifies your free-text note into a structured signal — bullish or bearish, with a confidence score — and folds it into the next forecast.
It's the closest thing to having an analyst on staff who reads every box score and every press release the moment it lands.
