Every AI answer, scored — before a human ever sees it.

LENS is LLM observability for AI systems. It ingests traces from every agent, runs an LLM-as-judge evaluation on each answer, and surfaces the weak ones on a dashboard — so bad responses get caught and fixed, not shipped.

The Outcome

What changes when LENS goes live.

Most teams ship AI answers they have never measured. LENS closes that gap.

Before → After
Blind AI quality becomes measured quality.

Every response gets a score from an LLM-as-judge, so you know how good your agents actually are instead of hoping.

Before → After
Silent bad answers get flagged before they ship.

Low-quality responses are caught the moment they happen and surfaced for review — not discovered later by a customer.

Before → After
No feedback loop becomes a live quality dashboard.

Weak answers collect in one place, so every fix feeds back into agents that keep getting better over time.

What It Does

LLM observability for the AI systems you already run.

LENS ingests traces from every agent, runs an LLM-as-judge evaluation on each answer, and surfaces low-quality responses on a dashboard so they can be fixed.

Instead of guessing whether your agents are good, you get a scored, searchable record of every answer — and a clear list of the ones that need work.

How It Works

Three steps, fully automatic.

From raw agent trace to a reviewed fix — no human scoring in the loop.

STEP 01

Agents send traces

Every agent sends its traces to an ingest endpoint as it answers, in real time.

STEP 02

A judge scores each answer

A judge queue evaluates each answer for quality with an LLM-as-judge — automatically, at scale.

STEP 03

Weak answers surface

Low-scoring answers surface on a dashboard for review and fixing, closing the loop.

Leverage

How teams put it to work.

LENS turns AI quality from a gut feeling into a metric you can act on.

Guarantee AI answer quality at scale

Score every response automatically, so quality holds up across thousands of answers — not just the handful a human happens to read.

Catch failures before customers do

Bad answers get flagged the moment they happen and reviewed internally — before they ever reach the people you serve.

Improve every agent with a continuous feedback loop

Each flagged answer becomes a fix that feeds back into your agents, so the whole system gets measurably better over time.

Questions

Common questions

What is LENS?
LENS is LLM observability for AI systems. It ingests traces from every agent, runs an LLM-as-judge evaluation on each answer, and surfaces the weak ones on a dashboard.
How does LENS score AI answers?
Agents send their traces to LENS, a judge model scores each answer, and the weak answers surface for review — so quality is measured instead of assumed.
Why do we need AI observability?
Because without it, AI answer quality is invisible until a customer complains. LENS is how you catch the failures before they reach anyone.
Who is LENS for?
Teams running AI agents in production who need to guarantee answer quality at scale and improve each agent with a continuous feedback loop.
How do we get LENS?
It depends on how many agents you run and where your traces live. Message the team on WhatsApp at +91 78277 85015 or email next@appd.ai.
