Cut AI costs

Prompt Compression Tool

Shrink your prompts without losing intent. Cut token spend up to 60% on every API call, across every major AI model.

  • 30–60% fewer tokens, same output quality
  • Works on OpenAI, Claude, Gemini, Llama
  • Token diff with before/after counts
  • Save compressed prompts to your library

Features

Everything you need for prompt compression

Intent-preserving compression

Keeps role, constraints, format, and examples while removing filler.

Token diff

See exact token counts before/after and per-model pricing impact.

Multi-model output

Compressed prompt previewed for each major model and tokenizer.

Aggressive mode

Push compression further when you need maximum savings.

Library integration

Save compressed variants alongside originals — fork and version freely.

Chain-ready

Drop compressed prompts into workflows for end-to-end cost savings.

Use cases

Built for real workflows

High-volume APIs

Production apps making millions of calls see immediate cost reduction.

Long system prompts

Trim bloated system messages without breaking behavior.

Few-shot heavy prompts

Compress examples while keeping signal density.

Agent stacks

Reduce tool descriptions and context overhead in agent loops.

How it works

From prompt to production in minutes

  1. Step 1
    Paste the prompt

    Drop any prompt — system, user, or full chain.

  2. Step 2
    Review compression

    See the token diff and intent comparison.

  3. Step 3
    Save and ship

    Store the compressed version to your library or pipe into a workflow.

FAQ

Frequently asked questions

What is prompt compression?

A technique that rewrites a prompt to use fewer tokens while preserving the original intent, constraints, and expected output.

How much can I save?

Typical compression ratios range 30–60% depending on the original prompt. Highly verbose prompts often compress more.

Does compression hurt quality?

Done well, no. InstructFlow AI's compressor preserves role, constraints, examples, and output format — it removes redundancy and filler.

Which models does it support?

Compression works for any text-in model: OpenAI, Anthropic Claude, Google Gemini, Meta Llama, Mistral, and more.
