Stay on course.
Websites, AI customer support and in-house data lookup: scope and price are agreed before work starts, the domain, the accounts and the data are in your name, and somebody keeps watching it after launch.

AI customer service
It reads your documents before answering, and every answer cites its source
Customers ask on LINE or on the website; when the answer is not in your documents it says so, hands over to a person, and never makes one up. HangRui's own LINE account runs on it.

In-house Data Lookup
Drop the catalogues in, and a colleague's question finds the page
PDF, scans, Excel and Word go into a folder and can be asked about seconds to tens of seconds later; the answer names the page and opens the file. It can run entirely on your own hardware.

Put the knowledge in the index, and the model can stay in the building
"It has to know our company's material" and "the material cannot leave the building" are usually two requests from the same person. As long as knowledge is something a model has to memorise, the two fight each other: the models that memorise the most are the largest, and the largest run in someone else's data centre. Put the knowledge in an index and let the model only read, and the two stop conflicting. This post makes the case from the published work: why retrieval works, why it pairs so well with a model on your own hardware, and what we built from it.

From DENDRAL to AlphaFold: what let AI into science was the assessment
In October 2024 the Nobel Prizes in Physics and Chemistry both went to machine learning, two days apart. Reading that as "AI finally got good enough" misses what happened. AlphaFold was accepted by structural biology because of CASP — a blind assessment, running since 1994, that hides the answer in advance. This is sixty years of AI for science in four stages, and what the real bottleneck was in each.
