The Problem: Context Tax
Every time you send a message to your AI coding agent, it doesn't just see your message. It sees your entire workspace context: your AGENTS.md, your SOUL.md, your TOOLS.md, your MEMORY.md.
These files are crucial. They define your agent's personality, capabilities, and memory. But they also get tokenized and billed on every single turn.
The Math
A typical AGENTS.md: 5,000 tokens
Average conversation: 20 turns
That's 100,000 tokens just loading your workspace — every conversation.
We call this the Agent Tax. The more detailed your agent setup, the more you pay per conversation. Bigger context = bigger bills = worse economics.
The Solution: Semantic Compression
48CTX is a context compiler. You paste your agent workspace files, we shrink them while preserving their meaning.
Not lossy compression like gzip. Semantic compression. We understand what the text means and rewrite it to say the same thing in fewer tokens.
How It Works
Basic Mode (Free)
- Removes redundant whitespace and formatting
- Consolidates duplicate instructions
- Strips unnecessary markdown structure
- Typical savings: 10-20%
Pro Mode (Beta)
- Uses Claude Sonnet to semantically rewrite content
- Preserves all behavioral directives
- Converts verbose prose to concise instructions
- Typical savings: 40-60%
Real Results
