The Local AI Agent OS
An always-on AI that lives on your machine — it plans work, writes code, builds its own tools, and structures your data so you can train cheaper models over time.
Your secrets are locked in hardware it can't touch.

Big Models Now.
Your Models Later.
Every AI agent today runs on massive, expensive models — even for simple tasks. Bytespace is designed to change that over time.
Day 1: Big Models
Frontier models handle everything. Every task gets structured by ctx0 as clean training data — not chat logs.
Week 2: Caching Kicks In
dom0 and cmd0 cache browser and desktop workflows. First run uses AI — reruns replay with zero LLM calls.
Month 3: Your Own Model
Fine-tune a small model with LoRA on YOUR workflows. It runs on consumer hardware. Frontier models stay for complex work.
In practice you'll use a mix of all three — frontier models, caching, and fine-tuned SLMs. The goal is to shift as much work as possible away from expensive models without sacrificing quality. Big AI labs aren't incentivized to help you do this — they make money when you use their models. Bytespace is built to break that dependency.
Everyone Gets
This Wrong.
Different tasks need different models.
You wouldn't use GPT-7 to answer Reddit comments. Small, fine-tuned models run on consumer hardware for pennies — and outperform frontier models on the specific tasks they're trained for.
But fine-tuning requires clean, structured data. That's why ctx0 formats everything from day one. When you're ready to train a cheap specialist, the data is already there.
LoRA Land — fine-tuned 7B models beat GPT-4 on 85% of tasksYou should. More data = more powerful.
An AI agent needs to know everything about you to actually be useful — your files, your habits, your workflows. That's terrifying if you don't know how your data is being used.
With Bytespace, your data lives on your machine, in a system you own. Your credentials are locked in hardware the agent can't extract. Nothing leaves your device unless you say so.
How the security architecture worksYour data is your most valuable asset.
Big AI labs train on your conversations, code, and ideas by default. OpenAI's terms say it plainly: "We may use Content to... improve our Services." Your work trains their next model. You get nothing.
If you're an expert in physics, law, or code — that's intellectual capital you should own. Fine-tune your own models. Sell your workflows. Or keep it all private. Your data is the asset. Start structuring it now.
OpenAI Terms of Use, Section 3 — "Our use of content"Four Tools. All Your Data.
Every tool captures a different type of interaction. Everything flows through ctx0 and is structured for training. All open source.
bot0
The Runtime
Plans work, writes code, builds its own tools, and runs for days.
Every decision, plan, and tool call → structured training data.
ctx0
The Memory
Persistent context across every AI tool you use. The single source of truth.
Normalizes everything into training-ready format from day one.
dom0
The Browser
Automates Chrome with native debugging — undetectable, cacheable.
Browser workflows, extractions, and navigation patterns → cached and logged.
cmd0
The Desktop
Controls your screen, keyboard, and mouse when there's no API.
Desktop interactions and screen workflows → cached and logged.
Good training data requires oversight. Bytespace gives you full visibility into agent workflows, the skills they build, voice transcriptions, and every decision they make. Review and correct anything. Agents also help — they keep your data structured through ctx0 and ask for your feedback when they need context to categorize or clean something up. The result: a dataset that's always ready for training.
