Agent Kernel is a minimalist framework that gives AI agents persistent state using just three Markdown files — one for memory, one for plans, and one for context. No database, no complex infrastructure. Works with any LLM provider and keeps agent state human-readable and version-controllable.

Extractor uses LLMs to reliably extract structured data from any webpage. Unlike traditional scrapers that break when HTML changes, Extractor understands the content semantically.
Reviewer scorecard
“The simplicity is the feature. Three Markdown files, git-trackable, human-readable. No ORM, no migrations, no database to manage. For agents that need persistent state without infrastructure overhead, this is the pragmatic choice. I would pick this over LangGraph's complexity any day.”
“Traditional web scraping is brittle. LLM-powered extraction that understands content structure is the right approach. Works on messy pages where CSS selectors fail.”
“Agent Kernel proves that the best agent infrastructure might be no infrastructure at all. Markdown as a universal state format means your agent's memory is inspectable, debuggable, and portable. This "files over frameworks" philosophy will age well.”
“Web scraping becomes web understanding. As more AI agents need to read the web, tools like Extractor become essential infrastructure.”
“Cute for prototyping but falls apart at any real scale. No concurrent access handling, no structured queries over memory, no way to prune state as it grows. You will outgrow three Markdown files the moment your agent needs to remember more than a weekend's worth of conversations.”
“The LLM cost per extraction makes it expensive at scale. But for high-value data extraction where accuracy matters more than cost, it is worth it.”
