Ask HN: Local LLM Recommendation?

I'm fairly new to the LLM landscape, so I'm asking for help in finding a suitable solution for my requirements.

For my work (software engineer) I usually take a fairly big amount of markdown notes as a braindump (and not particularly well organised).

I wanted to ask what are my options for a LLM that could be trained with my personal notes and provide answers to prompts in order to organise the ideas and information. Some examples would be:

- What is the deadline for X - Give me all the tasks that mention Y and have a due date of Z - Create an agenda for a meeting on A

etc..

Powerful reasoning is not essential (if that's the correct terminology), the focus would be on correctly identifying topics (in the above example).

Some additionalt requirements are:

- This would run on a commodity Linux machine, but with relatively modern specs (64Gb RAM, i7 Raptor Lake, but fairly average/low-end GPU) - I would need this to run in "air gapped" way. i.e. no outside transfer of information, since I might use data I don't want to share (even unknowingly)

Thank you
