I tried a lot of tools that help you to watch session replays and flag bugs! Kudos to @raealisa on Lucent - the first product I’ve tried that actually works!

people often think that the hardest problem to solve for any product intelligence tool is data pipeline or infra but instead the hardest thing to crack is how (rightfully) opinionated can you make your tool. you can show all the statistics on a dashboard and nobody would care but put a single valuable opinion and look at the product go to the moon. now i used to think that the opinions that our tool would have are my opinions(my team's) for a specific problem but lately i've realised that it's the wrong path. the right path is to actually make a product that gets opinions from the data it stores from real actual users. if onboarding A has more steps, is more annoying to complete, has a hard paywall, asks for a review, bla bla bla but it has a higher conversion rate(as per the sessions) than onboarding B which is much simpler and smaller, @lucent_ai must point that the better onboarding was A no matter what any human thinks. the next obvious question: how does the product really know when to form an opinion vs when to ignore when it sees a session? there is no right or wrong answer to this but we think of this problem a bit differently. its not about when to form an opinion vs when to ignore but rather its about in what medium is that data useful, to form an opinion. there must be one. the medium could be anything: aggregages: daily vs weekly features: bugs vs insights vs signalling end user: developers vs GTM every error, every successful session, every failed workflow has some magical insight hidden in it and we at @lucent_ai want to uncover it for you. come try us out(linked in the first comment) its free for the first 400 sessions btw.

career update: i have taken upon myself to end the misery of watching session replays by joining @lucent_ai. we are living in incredible times where we are automating(sorry ik this is worse than he who must not be named in 2026) everything that we are doing but people still have to look through session replays to uncover bugs and insights. at the same time, vision and text models have gotten smart enough to really understand user intent. put the 2 & 2 together and you'll realise lucent is solving the most annoying problem with a super obvious solution: ai watches your user sessions. slacks you the bugs and insights. everything you need to know to grow your product. super excited to get to solve this at day 0. LFG

AI removed the old bottleneck. Writing code is fast. The real challenge now is seeing what users actually hit in production and spotting the weird breakages that slip through. Lucent @lucent_ai nails this. It watches real sessions and surfaces the bugs and UX paper cuts that normally hide in hours of replay footage. Feels like running a 24/7 QA teammate on production. This will become standard in modern stacks. The demo says it all. This is 2026.

cost of writing code and shipping new features is trending to zero and the new bottleneck is deciding what to build or fix

your users are hitting bugs right now and not telling you we built @lucent_ai to fix this - it watches your session replays automatically and detects bugs + UX issues before users churn - connects to your posthog - AI watches every session replay - detects bugs + UX issues in realtime - alerts you in slack & creates linear tickets most teams find issues in the first hour they didn't know existed you can try it today for free, setup takes 2 mins if you're already on posthog :) lucenthq . com

it's true. 95% of users don't report bugs, they just churn this is why we built @lucent_ai. an AI that automatically watches your session replays to detect bugs and UX issues. how it works: 1. connect your posthog account 2. AI watches session replays 3. bugs get sent to your slack as users encounter them set up takes 2 mins if you're already using posthog :) lucenthq . com
If you use any software, you will hit bugs. Only a tiny 5% of your users will ever report bugs. The speed at which those bugs are fixed is the true measure of a founder in mastery of their craft.
