Show HN: Halgorithem – Catching AI Hallucinations Using Trees, No AI in Pipeline
Halgorithem is a custom algorithm that detects AI hallucinations without using AI itself, by parsing inputs into trees and comparing with file chunk trees to flag inconsistencies. It integrates with Python AI workflows like LangGraph and CrewAI, showing high accuracy in benchmarks.
Article intelligence
Key points
- Halgorithem detects AI hallucinations using tree structure comparison, without its own AI.
- Easily integrates into popular Python AI pipelines such as LangGraph, CrewAI, etc.
- Benchmarks show strong support rates across multiple topics, with only one unverifiable flag.
Why it matters
This matters because halgorithem detects AI hallucinations using tree structure comparison, without its own AI.
Technical impact
May affect model selection, inference cost, product capability, and evaluation benchmarks.

Detecting AI Hallucinations Before Them Happening
Whats Halgortihem
Halgorithem is a Custom Designed Algorithem For Detecting AI Hallucinations without Little to Any AI Present in the Algo Itself. Halgorithem was designed with speed in mind to quickly detect AI Hallucinating
How does Halgorithem Work
Halgorithem works by Parsing your files and input into a Tree which is compared with file chunks which were made into trees. If something doesn't make sense, Halgorithem Flags it.
Key Features
🔗 Fits Into Any AI workflow where responses are gened
Halgorithem can be integrated into AI Pipelines designed in python like LangGraph, CrewAI, PydanticAI and Microsoft AutoGen
First Robust Solution to AI Hallucination
Halgorithem is the first robust and true solution to hallucination detection over the alternitives.
