Sumitup Dev
What
Sumitup.Dev is a web blog for curated tech newsletters with an AI Agent for news summary and trend analysis.
Why
Reading tech newsletters is a way i used to stay on top of the rapid breakthroughs and changes AI has brought to the industry. However, Gmail is not a great place to read such long form newsletters: Trying to find your newsletters without getting distracted by billing emails or marketing emails is a hassle. In addition to this, some newsletters have a lot of sponsor messages, ad spots and banners. This motivates me to built Sumitup.Dev, a web blog where newsletters are delivered and process for a less distracting reading experience.
How
Powered by Gemini 2.5 flash, Sumitup.Dev’s backend gather all newsletters from a curated list everyday then intelligiently remove sponsor messages, banners, tracking links, … for a much more focused reading experience. These “cleaned” newslettes are then served on a web blog template from Quartz - a static-site generator that transforms Markdown content into fully functional websites.
To help clarifying new concepts or generally chat with the newsletters database, i also built an AI Agent using PocketFlow - a lightweight LLM framework by Microsft AI researcher Zachary Huang. I’ve tried Agno, Pydantic AI and LangChain but PocketFlow has proven to be the most straight forward and less bloated compared to other frameworks. The outcome is an agent who can summarize newsletters, be sent to read article link, perform various researches and websearch. One downside of this framework is that there’s no native logging capabilities - a crucial component to AI Agent dev, but LangFuse is a great open-source solution for AI Agent observability.
