The invisible engine behind every execution.
When you type a task, six systems activate in seconds: intent parsing, context enrichment, prompt selection, model routing, execution, and quality verification. Here is what happens between your input and the expert result.
The execution pipeline
Every task flows through six stages. Each one makes the result measurably better.
Step 01
Intent understanding
We parse what you need: task type, audience, context, constraints.
Step 02
Context enrichment
Your memory, your StylePrint, your preferences — all applied before prompt selection.
Step 03
Prompt selection & synthesis
We match your task to battle-tested prompts across 9 verticals — enriched by your context. Versioned. Scored. Continuously improved.
Step 04
Smart routing + provider tuning
We pick the right model and tune parameters. 8 providers. The one that scores highest for your task type.
Step 05
Execution
The composed prompt is delivered to the provider. Response streams back in real time.
Step 06
Quality gates + feedback loop
Every result is scored. Below threshold? We re-run with a different approach. Signals feed back to improve future runs.
