Shopify-first · read-only · advisory

An AI competitor brief every day, backed by real public market data.

Competitor research is necessary but painful. CompetitorLens monitors your competitors' public storefronts, detects what actually changed, and turns it into a short, evidence-backed brief written by AI: what moved and why it matters, without the manual grind.

Public data only · robots-respecting · we never write to your store.

AI daily brief evidence-backed · confidence 80/100

A rival cut your espresso price, and two refreshed their messaging.

The move that matters: BeanCo dropped a product you sell to $20.00 (you're $23.00). The rest is competitor-side context.

evidence

Written by CompetitorLens from evidence-backed signals. Advisory only. Nothing was changed or sent.

Merchants miss the moves that cost them sales

By the time it shows up in your conversion rate, it's days too late.

Silent price cuts

A rival undercuts your bestseller and you find out from your sales, days later.

Promos come and go

Discounts and bundles flicker across many stores, impossible to watch by hand.

Surprise launches

New competitor products appear without warning and eat your category.

Positioning drift

Hero, CTA and guarantee copy quietly change and shift the buyer narrative.

The old way vs CompetitorLens

Replace scattered, stale, manual checks with a system that remembers.

Spreadsheets, screenshots & agency reports

  • You check a dozen sites by hand, inconsistently
  • You catch changes late, or not at all
  • Screenshots go stale; there's no history
  • Agency reports are expensive and arrive monthly
  • Raw monitors dump diffs with no "so what?"

CompetitorLens, an AI market-memory engine

  • Public storefronts monitored continuously for you
  • A deterministic engine detects what actually changed
  • Structured history: the pattern, not just today
  • A daily AI brief: what moved and why it matters
  • Every claim linked to the evidence it came from

What we monitor

Price moves, stockouts, launches, promos, ad signals and website changes, monitored continuously and explained in one daily brief. Each fact comes from evidence; each carries an honest caveat when the data is thin.

$Same-product price comparison

See where a rival is cheaper on the same product, and where it's only a catalog-average difference, clearly labeled.

$Price-change alerts

Know when a competitor drops or raises a price, with the before/after and the evidence to back it.

!Out-of-stock & restock

Get alerted when a competitor sells out (a window to capture demand), and when they're back.

+Launches & removals

Spot competitor launches in your next brief, not a month later, and catch quiet discontinuations.

%Promotion alerts

See when a rival starts a sale, and when it ends, so you can counter, hold, or wait it out.

Ad & campaign signals

Catch new competitor campaigns from public ad signals. No private data, no guessed spend.

Website & messaging

See when a competitor changes their pitch (hero, CTA, positioning), before/after, side by side.

Assortment breadth

Watch a rival expand or thin out their range over time, a breadth strategy you can match or counter.

Market memory

Not just today's change. The pattern behind it: promo cadence, pricing trends, who moves first.

Evidence-backed, and honest when the data is thin

A deterministic engine decides what's true; AI writes the brief. Every claim links to its source, and when we can't be sure, we say so.

Every claim links to its source

When the data is thin, we tell you, we don't guess
⚠ BeanCo: some product pages could not be checked today, so category averages are marked directional.
⚠ Prices not compared across currencies (GBP vs USD).

A same-product claim only appears when we can confidently match the product. Otherwise we show catalog-level positioning and say so. No fake "matched SKU."

How it works

STEP 1

Add your competitors

Paste competitor websites or accept suggestions. Public storefronts only.

STEP 2

We watch competitor changes

CompetitorLens tracks changes to competitor products, prices, promos, stock, and website messaging, then turns the important ones into a brief you can actually use.

STEP 3

We match products when the evidence is clear

We compare the same product when we can confidently match it; otherwise we show category-level positioning.

STEP 4

AI writes your brief

A short daily, weekly and monthly brief: what changed, why it matters, every claim cited.

STEP 5

You decide

Advisory only. CompetitorLens informs your pricing and product decisions; it never makes them.

Who it's for

Founders & small teams

"I know I should watch competitors but I don't have time, and I find out too late." One brief a morning.

Ecommerce managers

"I manually check a dozen sites; it's inconsistent and I miss things." Consistent, every day.

Growth marketers

"I need to know about promos and launches to react, not read about them next month."

Agencies & niche verticals

Monitor many client stores from one copilot, account-scoped per client. Built for catalogs that matter (e.g. cloth by weight/weave).

Built to be safe

FAQ

Do I need to own the competitor stores?

No. CompetitorLens only reads public competitor storefronts, the same pages any shopper sees.

Does this change my prices automatically?

No. There is no auto-repricing. CompetitorLens is advisory only. It informs your decisions, it doesn't make them.

Do you access competitors' private ad accounts or spend?

No. We surface campaign signals from public sources only and never estimate private budgets.

What if a price isn't really comparable?

We only make a same-product claim when we can confidently match the product. Otherwise we show catalog-level positioning, and we don't compare prices across currencies. We tell you.

How long until it's useful?

A baseline appears after the first checks; weekly patterns after ~7 days; monthly trends and performance links after ~30 days.

Is the demo real customer data?

No. The demo is fully synthetic and labeled as such.
