Meaning-First Compression
Retains critical information, intent, and structure—so your models stay effective.
Cut your LLM API Costs by 65%.
For teams running chat, RAG, support, or coding agents. SuperCompress removes low-value context before inference—so your models do more with the tokens you already pay for.

Prompt compression · RAG context · chat memory · CPU-only policy
Consumer AI apps send chat history, retrieved docs, tool traces, and user context on every request. That context drives LLM API cost, latency, and context-window pressure before the answer is generated. SuperCompress runs before inference, selecting the context most relevant to the current user request. Use it for chatbots, AI search, support agents, copilots, RAG, and any feature where context grows with users.
EXAMPLE: LONG CONVERSATION20,814 TOKENS
const result = await compress({
model: "supercompress-v1",
input: conversation,
preserve: "meaning",
target_reduction: "max"
})
// → 4,210 tokens (82% smaller)

HOW IT WORKS
Compress before
the model call.
- 01 Ingest Chat, RAG hits, tool traces
- 02 Score Relevance vs current ask
- 03 Keep Meaning-first retention
- 04 Ship Fewer tokens to inference
Context arrives oversized — history, docs, and traces piled into one prompt.

USE CASES
Use Cases That
Compound
From agentic coding to document-heavy work, meaning-first compression helps teams do more with less—without losing what matters.
Coding Agents
Compress task history, repo context, tool traces, and diffs so agents reason farther inside the same context window—and spend less per turn.
- Shrink multi-file diffs before the model call
- Keep plans + decisions, drop stale tool noise
- Works as an MCP plugin across Cursor, Claude Code, Codex
Long Conversations
Keep long chats useful and coherent. SuperCompress retains the decisions, constraints, and facts that drive better answers—not every filler turn.
- Lower cost on multi-hour support or sales threads
- Preserve user preferences and prior commitments
- Reduce latency as history grows
RAG & Search
Retrieved chunks often drown the query. Compress retrieved context so the model sees the evidence that matters for the current ask.
- Cut redundant passages across top-k results
- Keep citations and key claims intact
- Fit more evidence into the same budget
Support Copilots
Ticket history, macros, and knowledge-base hits add up fast. Compress before generation to keep replies accurate without burning tokens.
- Prioritize current issue + account state
- Drop repeated boilerplate from prior tickets
- Ship faster replies at lower per-ticket cost
Document Workflows
Specs, tickets, research notes, and PRDs are dense. Compress for reviews and synthesis while retaining requirements and decisions.
- Faster design and compliance reviews
- Keep must-have constraints and open questions
- Pair with human-in-the-loop editing
Production Inference
Reduce token usage and latency in live apps while preserving output quality. Run locally on CPU or deploy beside your API gateway.
- 5–20ms local compression path
- Drop-in before OpenAI, Anthropic, and more
- Meaning retention built for product workloads
