AI Builders Hackathon 2026

LeakLens

Private, explainable AI that finds the leaks between website traffic and revenue.

No API key

Runs locally

Browser-side zero-shot classification keeps analyzed website copy private.

Explainable

Evidence first

Every risk is tied to an observable signal, not an opaque AI score.

Actionable

Prioritized fixes

P1/P2/P3 remediation turns diagnosis into a concrete conversion plan.

01 · Problem

Small businesses buy traffic before fixing the last 10 feet.

Phone-only scheduling, wrong currency labels, vague CTAs, weak trust proof and generic positioning silently waste high-intent visitors. Traditional audits are either static checklists or black-box LLM reports.

02 · Solution

A conversion audit you can inspect.

Paste the visible homepage copy. LeakLens produces a 0–100 conversion-health score, ranked evidence-backed findings, and prioritized remediation.

45/100
High · Booking depends on a phone call
High · Potential currency mismatch
Medium · Trust proof is thin
03 · Product flow

04 · Technical architecture

AI where it helps. Rules where they’re better.

Deterministic layer

Observable evidence

CTA language, online booking, forms, price markers, currency context, social proof and differentiation.

Semantic layer

Browser-side AI

MobileBERT MNLI via Transformers.js classifies friction, trust, CTA strength and positioning.

Fusion layer

Confidence thresholds

Semantic risks affect the audit only when model confidence clears explicit thresholds.

05 · Responsible AI

Private by design. No prompt theater.

Local inference

Business copy is not sent to an LLM provider.

Fallback works

The product remains useful in rules-only mode if the model cannot load.

Confidence ≠ fact

AI findings are labeled as risk signals and paired with human-readable evidence.

06 · Users + value

Audit before you spend another dollar on traffic.

Local businesses

Catch booking and trust leaks before buying ads.

Agencies

Produce fast, consistent prospect audits without sending client copy to a third party.

Growth teams

Use the score as a repeatable pre-launch QA layer for landing pages.

07 · Roadmap

From copy audit to conversion observability.

Next: consent-based URL ingestion → screenshot hierarchy analysis → accessibility/mobile signals → analytics integrations → vertical-specific scoring → before/after outcome tracking.

08 · Try it

Find the leak. Fix the leak.
