COGNITIVE AI INFRASTRUCTURE
Your AI shouldn't start from zero.
Yoystro gives the AI models and tools you already use a persistent memory. What they learn once can be reused. Less work is repeated, fewer model calls are needed, and more gets done with less time and cost.
Keep the models, tools and subscriptions you already have. Yoystro works underneath them.

03 · THE COST
Every new task shouldn't feel like day one.
Today's AI tools relearn the same context on every task. They reread the code, rediscover the rules and make the same decisions again. You pay for that forgetting every month.
CONTEXT READ ACROSS THE SAME FIFTY TASKS

The heaviest model71.2M
What is learned once is not reread on every task.
04 · WHAT CHANGES
It remembers. It reuses. It decides. It checks.
Remembers
Learns your code, decisions and rules once. Carries them across sessions, tools and models.
Reuses
Doesn't relearn what it knows. Finishes familiar work without thinking twice.
Decides
Gives each task the thinking it deserves. Never spends more.
Checks
Tests the result before handing it over. You receive evidence, not just output.
04b · ADVANTAGES
What you gain.
They work together; none is sold alone.
Persistent company memory
Explain something once and never again. What is learned survives the session and moves with you when tools change.

Reads just enough
Opens the page it needs, not the whole library. Less reading, less waiting.

Zero-cost automation
Familiar work is recognized, not rethought. It closes at no cost.

Predictable cost
Spend is counted continuously and you set the ceiling. The budget outlasts the work.

Independent verification
No delivery passes on its own word. Tests run, acceptance is measured.

Ahead on hard work too
Easy tasks get done everywhere. The gap opens on the hard class.
Hard class 7/8; most models 4/8

Less output, less time
Writes less, finishes more. Among the shortest model-time bands on the same fifty tasks.
119K output, ≈64 min; the slowest model 690K, 134 min

Model and tool independence
The same memory works under every model and tool. You keep your stack.

To a human at the right time
When the automatic layers can't finish, the task reaches the right person with a structured report. No blind retries.

05 · YOUR STACK STAYS YOURS
Works with the AI you already use.
Yoystro is not a model. It is not another coding assistant. It sits beneath the models and tools you already use. Your subscription, your model and your editor stay yours; Yoystro becomes the memory and cost intelligence underneath them.
- Keep your model
- Keep your tools
- Work runs on your own infrastructure
- Your keys stay masked

RUN IT ON YOUR WORKLOAD07 · BENCHMARK
Same work. Less thinking. Less cost.
Same model. Different system.
The model tier Yoystro uses scored 43/50 on its own. The same model scored 48/50 under Yoystro. The difference came from how the work was remembered, chosen and verified, not from a stronger model.

Ten hard tasks on a real production codebase. Yoystro entered this measurement with three weeks of accumulated company memory; the tools it was compared with relearned the codebase on every task. One task finished without any rethinking because it had already been learned. This is an internal measurement; its method is separate from the published benchmark above and the two are never combined.

09 · TRUST
Your data, your rules, your evidence.
- Work runs on your own infrastructure. Your code is never hosted with us.
- Your keys stay masked. Nothing beyond what is needed is ever seen.
- Every delivery comes with evidence: test output, measurements, decision trail.
- Company rules are learned and applied. A retired rule is never used again.
