kbird · Kristopher RichardsGetting Started with Frontier Agents, Free
October 30, 2026
The best personal agent setup available right now costs zero dollars. Not a trial that expires before it gets useful, and not a crippled demo. Working agents, doing real errands and real work, free. The catch is that almost everyone sets them up wrong, because the part that makes an agent good is not the model. It is the teaching.
Start with two free agents
Hark Pro (hark.com, or the app on your phone) runs errands on the web: filling out forms, booking things, working through websites the way a person would. Every feature is available on the free plan. The paid plans only raise how much you can use it, so start free and stay free until a limit actually blocks something you care about.
Muse (muse.ai, or the Muse app) is a personal agent with its own computer. It works with files, browses, keeps track of things, and runs checks on a schedule while you do other things. The free plan has usage limits and runs on the lighter model, which is still plenty to learn on and get real work done.
Between the two, you have an errand runner and a worker. Total cost: nothing.
The part most people skip
An agent you just opened is a new hire on their first morning. It gets useful when you write things down for it once instead of repeating yourself forever.
On the first day, give it a short note about you: your name, where you live, what you are working on, what you care about, and how you like things done. Then live by three habits:
- When it gets something wrong, correct it once and ask it to remember the correction. Good agents keep what they learn.
- Keep one running note of lessons and preferences, and have the agent read it. This is the whole secret behind setups that look impossibly capable. The writing is the training.
- Start with one small, real job. Read the result carefully. Trust grows from checked work, not from promises.
Optional power step: your own private network
Tailscale (tailscale.com) is free for personal use. It links your own phone and computer into one private network, so they can reach each other from anywhere without exposing anything to the public internet. If you ever want a tool on one device to work with files or services on another, this is the safe way to connect them. Ten minutes to set up, and it is the same foundation much bigger home setups are built on.
How to stay at zero dollars
- Free tiers refill on their own clocks, weekly or monthly. When one runs out, switch to the other tool instead of paying. Spreading across services is a feature, not a compromise.
- Save paid upgrades for the day a free limit actually blocks something important. Most people pay long before that day comes.
- Your time reviewing work is the real currency at this level. Spend that, not money.
Safety basics, because these agents act in the real world
- Connect accounts in order of how much they matter, least important first.
- Review anything before it is sent, booked, or paid for, until the agent has a track record with you.
- One errand at a time at the start. Speed is not the point; a checked result is.
That is the whole starter kit. Two free agents, one honest note about yourself, corrections saved as lessons, and patience with the refill clocks. The frontier is not behind a paywall. It is behind a first day of teaching, and that part was never for sale.
