Once you have a local agent you can actually trust is not sharing your conversations anywhere, you just use it like a really smart search engine, and your need to use a web browser mostly goes away.

Some of my recent use cases...

Help me find cheap flights and a hotel and plan some interesting sights to see because I am speaking at x conference on x date.

Download all my favorite music from x streaming service as FLAC files locally, then convert them to OGG and put them on my portable music player.

Download all my youtube subscriptions locally to this folder and strip out any ads or sponsored content.

Here are a list of all the books I own. Can you find me DRM-free epub copies and put them on this e-reader for me?

Here is a picture of an object next to a measuring tape. Can you 3d print me a holder perfectly sized for it based on a openscad file i can easily tweak?

I am really stressed right now. Can you help me talk through everything I have to do and help me rationally prioritize? Can you remind me and keep me on track and be my fake boss for today?

Can you look through my email and keep track of any appointments or invites so I stop missing meetings?

I follow the same approach (finding LLMs useful but only running open models on my own hardware) but I've been limited by also not letting them into my email and being pretty restrictive about their internet access. Would you mind sharing what stack and agent harness you use, since your other comments make it clear you're highly restrictive about what kinds of tech you run at home and I assume you vetted it thoroughly, and it sounds like it's working well?

I'm wondering specifically about things like what kind of tool or restrictions you use on web browsing to avoid being flagged as a bot and how you guardrail access to your email (to avoid, say, the LLM deciding that "help me organize" includes telling people you want to reschedule). I use Qwen 3.8 26b at home and find it very useful for some tasks but when I think of using it as a general assistant rather than coding assistant, I keep thinking of times it has gone wildly wrong (e.g. it once spent 20 minutes trying to get around Supabase authentication because it couldn't figure why a certain call wasn't working)

Thanks for the useful tasks. If I actually had your setup, I might do those things. Like you, I am not going to ask Meta, et al. to do those things. I also am hesitant to invest in setting up a new system. However, I do have a M2 Mac Studio, so maybe I am closer to being able to run a local system than I thought.
