How DAAM verifies every price it shows
Where DAAM’s prices come from and the checks each one passes: source links, evidence, plausibility, freshness, fair seller counting and confidence levels.
Published 5 min read
The short answer
Every price DAAM shows comes from a stored observation with the seller page it was read from, the time it was seen and a short evidence snippet. Before a price can appear in an answer it passes checks for evidence, plausibility and sudden jumps; each seller gets one vote in the market range; out-of-stock prices don’t count; and every answer states how confident it is.
Key takeaways
- The rule: every price traces back to a source URL, a timestamp and an evidence snippet. AI never originates a price.
- New prices are checked against the page’s own text, against normal ranges for the category and against sudden jumps.
- Unusual changes are held for review instead of going straight into answers.
- Each seller gets one vote, out-of-stock prices don’t count in “market now”, and robust statistics resist outliers.
- Confidence is shown on every answer: high, medium, low or “not enough evidence”.

The one rule
DAAM is built around a single rule: every price a user sees traces back to a stored observation with a source URL, a timestamp and an evidence snippet. The AI in DAAM reads web pages and photos, matches products and explains results in plain language — but it never makes up a number. If there isn’t enough evidence, the answer says so.
Where prices come from
- Sellers’ public websites. DAAM’s crawler, DaamBot, reads publicly listed prices. It identifies itself, respects each site’s robots.txt, limits how often it visits (by default no more than one request every two seconds per site), prefers catalog feeds over crawling page by page, and never logs in or gets around protections. Sellers can ask for corrections or opt out on the DaamBot page.
- Official sources. Government notifications and published rate lists are read as their own class of source.
- Receipts people choose to share. When someone adds a price anonymously after a photo check, it becomes a separate, clearly labelled kind of evidence. See sharing prices anonymously.
Listings are re-checked on a schedule that adapts to how often a price actually changes — electronics more often than restaurant menus — and a product can be re-checked on demand when someone asks about it.
The checks each price passes
Before a new price can count, it goes through a series of checks:
| Check | What it catches |
|---|---|
| Evidence | The price must appear in the text read from the page, not just in an extraction |
| Plausibility | Prices far outside the normal band for the category are held back |
| Sudden jumps | A big change with no sale or price-cut markers on the page is quarantined |
| Cross-source | Prices that disagree sharply with other sellers are looked at again |
| Double-read | Doubtful extractions are read a second time |
Quarantined prices go to review. An AI review may classify an obvious case — a sale price, an installment amount, a bundle, the wrong variant — but it acts only when it is highly confident; everything else goes to a person. Prices that fall outside the category’s plausibility band always go to a person.
How the market range is calculated
A fair range needs fair counting:
- One vote per seller. A shop with twenty listings doesn’t drown out a shop with one.
- Robust statistics. The median and the middle half of prices resist a single outlier; clear outliers are set aside.
- Out-of-stock prices don’t vote in “market now”. They still appear in the offers list, marked as out of stock.
- Like with like. Prices are separated by what changes them: PTA status and warranty for phones, cash versus installment, city for building materials and restaurants, dine-in versus delivery apps.
The cheapest verified in-stock offer is kept separately, because it is the money-saving answer: the lowest current price you could actually pay, with a link to check it yourself.

Freshness: how old is too old?
Every price shows when it was last checked, and each category has its own idea of fresh:
- Electronics move fastest: under a day is fresh, under a week is recent.
- Construction materials: under two days is fresh, under a week recent.
- Clothing: under two days is fresh, up to two weeks recent.
- Restaurant menus change slowly: under two weeks is fresh.
Older prices are labelled as ageing or stale, and an answer built on stale prices gets a lower confidence.
Confidence you can see
Each answer carries a confidence level:
- High — at least three sellers and several recent listings that broadly agree.
- Medium — at least two sellers with reasonably consistent prices.
- Low — thin or scattered evidence; use with care.
- Not enough evidence — DAAM won’t give a verdict. It tells you what it found and asks the one question that would help. Here’s why that matters.
When something looks wrong
Every answer has a “Price looks wrong?” button. Tell DAAM what you saw and the price is queued for a re-check. Sellers can also report a wrong price or opt out through the DaamBot page. Mistakes are fixed at the source, so the correction shows up for everyone.
Frequently asked questions
Where does DAAM get its prices?
From publicly listed prices on Pakistani sellers’ websites and official sources, collected by DaamBot within each site’s robots.txt rules, plus prices people choose to share anonymously after a receipt check. Every price keeps its source link, time and evidence.
Does DAAM use AI to guess prices?
No. AI reads pages and photos and explains results, but every price shown comes from a stored observation with its source and evidence. When there isn’t enough evidence, DAAM says so instead of estimating.
How does DAAM handle fake or wrong prices?
New prices must appear in the page’s own text, fall within a plausible range and not jump without explanation. Suspicious prices are quarantined for review, and each seller gets only one vote in the market range.
What does the confidence level mean?
It tells you how strong the evidence is. High means at least three sellers with recent, consistent prices; medium means at least two; low means thin evidence; “not enough evidence” means no verdict is given.
