I've been doing competitor research and customer analysis for a while, and the process always looked the same: open Trustpilot, scroll through hundreds of reviews, manually tag themes, try to spot patterns, paste quotes into a doc. Hours of work for something that should take minutes.

So I built ReviewLenz.

You go to any Trustpilot review page, click the extension, pick a time range (last month, 3 months, year, whatever), and it collects all the reviews through your own browser session. Then AI analyses everything and gives you a full report:

Sentiment breakdown and NPS estimate

Positive and negative themes with real customer quotes

Quality dimensions scored 0-10 with trend direction

A prioritised 5-step action plan

Customer segments

5 direct competitors with strengths, weaknesses, and switch risk

Ad creative directions based on what customers actually say

Live competitor ads from Meta Ad Library sorted by how long they've been running

The whole thing takes about a minute. No account needed, no login, no API keys to configure.

I'm most proud of the creative directions tab — it takes customer language from reviews and turns it into ad hooks, objection-handling angles, and competitor positioning headlines. If you run paid ads this is genuinely useful.

It's free right now while I figure out pricing. The only paid feature is downloading the raw review list as a PDF.

Happy to answer questions about how it works. Built with GPT-4o for analysis and the Meta Ad Library API for competitor ads.

I was going trough trustpilot page reviews and burning hours of manual work. Now i do it it 5 mins with this extension
