AI price and stock monitoring
Faodu is an AI-assisted price tracker for online products. Paste a link, review the price and stock fields, and choose a check schedule. Get alerts when checks detect price changes or items back in stock, without writing code.
Create an account or sign in to add your first product link.
Demo: a product link is pasted, AI outlines the price and stock on the page, the price chart updates as the price drops from ฿1,290 to ฿990, and an alert is sent to Discord.
The “Baicha” shop, link, prices and chart are examples. The demo’s 5-minute checks and Discord alerts require Pro or above.
Make each check useful
Choose product pages and the fields that matter, set conditions for each link, and review check results and history in one place.
Set a price threshold or percentage-drop alert. Review the price history for that link to help decide when to buy.
Track the availability text on a product page and receive an alert when a check detects that the item is back in stock.
Add product links from the shops you follow. Review each item’s price and changes to inform your pricing decisions.
Free reads data from a page’s HTML. Prices loaded by JavaScript require Chrome on Pro or above. Compatibility depends on the website. See website compatibility limits
How it works
Four steps take you from a product link to alerts that don’t fire on every check.
AI reads the shop page and suggests fields first, like price and stock. Want something else too? Click it on a screenshot of the page with Visual Selector.
Choose a check interval within your plan’s limits, starting at every 60 minutes on Free. Pro and above can set days and hours for each link, such as every 15 minutes on weekdays, 09:00–18:00 Bangkok time.
Get alerted when a price goes below or above a number, into a range, drops or rises by a percentage, or when the page text contains the word you are waiting for. Combine them with “all” or “any”.
When the price falls below ฿500 you get one alert. The next check that is still below stays quiet, until the price goes back up and falls again.
Features
Browser Steps let Chrome fill fields, click, choose a size or colour, and wait for a price to load, with up to 20 steps per link. If a step fails, the check stops and reports the error. Compatibility depends on the website.
Email and in-app alerts are included on every plan. Add Discord from Pro or webhooks on Enterprise, triggered when a check detects the changes you choose.
Price and status history charts, kept for 7 to 365 days depending on plan.
Use an HTTP or HTTPS proxy with a username and password, as a default for a whole website or for one link.
Proxy passwords, steps marked secret and Discord webhooks are encrypted in the database and never sent back to the browser.

See all plansFaodu is a web app for tracking online product prices and stock. Paste a product link, let AI help select fields such as price and availability, then check the page on a schedule.

No. AI suggests fields such as price and stock first. If one is wrong, or you want to track something else, click it on a screenshot of the page with Visual Selector. You can still type a CSS selector yourself if you prefer.
Compatibility depends on the website. Free reads prices and text present in the page’s HTML. Pages that load data with JavaScript require Chrome on Pro or above. Pro also includes up to 20 Browser Steps for login or product options. Pages requiring OTP codes, CAPTCHAs or sign-in on another domain may not work automatically. Review the extracted values before enabling a monitor.
The shortest check interval is every 60 minutes on Free, 5 minutes on Pro, 2 minutes on Business and 1 minute on Enterprise. You can choose a longer interval. Pro and above can also set days and hours for individual links, such as weekdays 09:00–18:00 Bangkok time.
Every plan gets email and the in-app bell. Discord is available from Pro, and webhooks on Enterprise. Choose alerts for price changes, status changes, back in stock, or conditions you set, such as a price below ฿500.
Yes. Free costs nothing and includes 5 product links, checks as often as every 60 minutes, 10 AI analyses a month, 7 days of history, email and in-app alerts. Free reads page HTML without Chrome. Upgrade for faster checks, more links or pages that need JavaScript.
Faodu checks on a schedule rather than watching every second. It evaluates your alert settings after a successful check. The first successful check establishes a baseline and does not send a change alert. Alert timing depends on your interval, the website’s response and your chosen delivery channel.
