Sound Familiar?
You don't know if the content you received is actually AI-generated.
Your intern submitted a report. A client sent a proposal. A student turned in an essay. You have no idea how to verify it without uploading it to a sketchy detector that might store your data.
Every AI detector out there is a black box.
GPTZero, Turnitin — they all use ML models you can't see, audit, or trust. And they still produce false positives on your own writing.
The problem isn't that LLMs exist. It's that nobody built the right tools for the humans working with them every day.
Imagine This Instead.
You paste. You know. In seconds.
You drop in any text and get an instant heuristic scan: a 0–100 AI-likelihood score with color-coded explanations. No mystery. No ML. Just logic you can read.
Your output is clean before it ever leaves the tool.
One click converts messy LLM output to structured Markdown, valid JSON, clean CSV, or a polished PDF. No more manual cleanup.
You finally trust what you're working with.
Whether you're a teacher reviewing essays, a dev parsing API responses, or a writer cleaning up drafts — you have full transparency into what's AI-influenced and what isn't.
There's a new way to work with LLM content — and it doesn't require handing your data to another AI.

Before & After
Raw LLM output
As an AI language model, I can certainly help with that. Below is a comprehensive, step-by-step breakdown that will walk you through everything you need to know in order to get started quickly and effectively...
Pruned & formatted
# Summary - Clear overview of the goal - 3–5 concrete steps - Bullet-pointed follow-up actions Tone: direct, human, no boilerplate.
Common use cases
Educators
Scan essays for AI-like patterns while keeping student work on-device.
Writers & editors
Strip boilerplate from drafts and normalize tone before handing to an editor.
Engineers & ops
Clean up LLM-generated tickets, docs, and runbooks into predictable formats.
API testing
Format and validate LLM API responses for JSON, CSV, or Markdown pipelines.
Research & analysis
Assess AI-likeness in surveys, transcripts, and datasets with transparent heuristics.
Content moderation
Flag synthetic text in submissions while keeping sensitive content local.
I built Pruneify because I was tired of either guessing whether content was AI-generated, or spending 20 minutes cleaning up LLM outputs by hand. This isn't another AI wrapped in AI — it's programmatic, transparent, and fast. No model. No guesswork. Just rules that work.
