LinkedIn TL;DR
Built and personally used a Chrome extension that turns long LinkedIn posts into one-sentence takeaways.

The problem
I wanted to find useful ideas in my LinkedIn feed without reading every long post in full. Getting to the takeaway takes time—good for LinkedIn, less useful for readers. In my experience, insights are often buried in repetitive writing. Sometimes there isn’t a takeaway at all, just AI slop.
What I built
I built a Chrome extension that places a quick summary and a one-sentence key learning alongside the original post. It helped me decide which posts deserved a closer read.
The prototype explored Chrome’s on-device AI, included a local fallback, and cached repeated posts.
Key decisions
- Keep the takeaway in the feed so it fits the reading workflow and looks natural.
- Use one sentence to support a quick decision about reading further.
- Keep the original post accessible for context and deeper reading.
- Explore local processing and caching to reduce waiting.
Results & what’s next
Results
- Built and personally used the extension to extract takeaways from long posts.
- The prototype was not tested with a broader user group after LinkedIn flagged my account.
What I learned
This was the first Chrome extension I had built, so learning how to set it up was a valuable part of the project.
The speed of generating the summary and key learning was crucial. When it took too long, the wait weakened the benefit. LinkedIn also flagged my account during use, making platform compatibility an important constraint.
What I’d test next
I would explore alternative LLMs to improve response speed and research a compliant way to deliver the experience before sharing it publicly.

What our launch taught usIllustrative business post · not a live demo
We spent weeks adding features because prospects kept asking for them. More demos came in, but conversion barely changed.
When we watched customers get started, the real issue was clear: setup took too long. We simplified onboarding before adding anything else.
TL;DR
More features didn’t solve the sales problem. Simplifying onboarding addressed the friction customers actually faced.
