Lucent
Hey Product Hunt! I'm Alisa, founder of Lucent (backed by YC and Ryan Hoover :)
We built Lucent because we kept seeing the same problem at every company we worked at - bugs and UX issues slipping into production and nobody catching them until users complained. The data to find these issues was already there in session replays, but nobody has time to actually watch thousands of sessions.
So we built an AI that does it for you. Lucent watches your session replays automatically and surfaces bugs and UX issues in real time, with full reproduction context sent straight to Slack and Linear.
How it works:
1. Connect your PostHog account
2. AI watches session replays 24/7
3. Bugs get sent to your Slack or Linear as users encounter them
To get started, you can get 400 sessions processed for free and see what issues your users are coming across - most teams find issues in the first hour they didn't know existed. Sign up here: lucenthq.com
Trusted by teams obsessed with product quality, like Reducto, Browser Use, Productlane, Julius, Finta, Happenstance, and Evidence.
Would love for you to try it out and let us know what you think - happy to answer any questions!

@alisarae Congrats on the launch, Alisa! 🎉 This is solving a real pain — session replays are gold but nobody actually watches them. The direct Slack/Linear integration is the key insight here, it makes the signal actually actionable rather than just another dashboard to check. About to launch OceanMind, an AI-powered breathwork iOS app, and the idea of having an AI catch UX issues in the first hours post-launch instead of waiting for 1-star reviews is genuinely compelling.
Q:Does it work with mobile web sessions too?

Good job team. The pain of watching dozens of replays is real. If AI can do it and summarise the findings, that's huge. Do you work with tools like clarity etc. or you have own session replay tool?
I wish you good luck today!

Congrats on the launch! I can totally see the value here. Wonder whether the session replay companies will add their own version of this capability in time.
When you say you will launch your SDK, does that imply that either the underlying product companies or your customers will need to build towards you? If the former, their incentives may not line up. If the build is as simple as the current implementation of those underlying companies, cool. If complicated, can see me not wanting to spend my eng resources on it.
I think the feature hits a definite mark though. The premise is dead on. Early stage, you obsess over each. As time goes on, it's harder to spend the time watching and mining for friction. Now you just have tools out there creating data "just in case I need it"... internet lint. ;-)
The session replay angle for issue detection is interesting - we"ve had Datadog and LogRocket running for a while and the gap I keep running into is that replays tell you what happened but not why it matters. Is Lucent doing its own severity scoring, or is it more like "here are the unusual patterns, you decide"? Wondering how it handles the noise problem - low-signal rage clicks vs. something that actually broke the flow.

Super interesting—does Lucent only detect technical bugs, or can it also flag UX friction (like rage clicks, dead ends, confusing flows)?
The latter would be insanely powerful for product teams.

Congrats on the launch, @alisarae. I spent almost five minutes on the site. The quote that hit me hardest was from Justin Lee: "We installed Lucent on a Friday, by Monday morning it had filed 7 bugs we'd never seen."
That one line does more selling than any feature list. It captures the speed and the value.
One small observation while poking around. That quote is mixed in with a wall of other testimonials. It deserves its own space, maybe right under the hero. Let it breathe.
Anyway, it was just something I noticed. Hope the launch goes well.

Does Lucent only detect bugs or also UX issues

AI-powered session replay analysis is a smart idea — manually reviewing recordings is painful. How do you handle privacy-sensitive sessions? Do you have options to mask or exclude certain user data from the recordings?
