Agencies
Produce work across multiple clients without letting the model flatten them into one generic voice. Slop Sentry removes familiar AI habits, keeps each client recognizable, and brings every draft into AP style compliance.
A fast first draft only gets you so far when it still sounds like everyone else's AI-generated copy. Slop Sentry catches the AI tells before your readers do, from the em-dash pileups to "It's not about X. It's about Y." Then it rewrites the draft until it reads like content you can stand behind.
Slop Sentry works inside the tools your writers already use: Claude, ChatGPT, Suits.ai, and any AI assistant that supports MCP, the plug-in standard that lets them call outside tools.
No credit card. 5,000 words a day on the free plan.

Use AI across marketing and communications without making every expert sound the same. It keeps experts recognizable and clears vague AI language from everything else your team publishes.
Before and after
Go from confusing, jargon-heavy writing to clear prose with the press of a button.
In today's fast-paced digital landscape, brands need more than content—they need connection. We're thrilled to announce a game-changing partnership with Acme Analytics. Starting in March, its dashboard will seamlessly plug into our reporting platform, helping client teams unlock campaign results in one place instead of exporting spreadsheets from three tools. This isn't just a dashboard. It's a paradigm shift. The result? Early testers were able to delve deeper and cut weekly reporting from four hours to 40 minutes.

The rewrite retains every original fact and removes all six flagged writing patterns.
Add Slop Sentry to your AI assistant and run the same checks on your own draft. Start free.
The approach
Most tools stop at pattern matching or a long prompt. Slop Sentry runs a multi-engine editorial pass across the entire skill: exact code where the rule is exact, and specialized judgment where context decides.
400+
More than four hundred checks cover banned language, structure, rhythm, formatting, repetition, substance, tone, and AP Style. One request exercises the whole library, not a short blocklist.
Beyond patterns
Code catches exact AI tells. Separate engines evaluate whether the draft says anything concrete, slips into hokey tone, or breaks AP Style. Pattern lists alone cannot answer those questions.
Rewrite loop
Every revision goes back through the same checks. Fixes that introduce new problems get caught before the draft leaves the conversation.
What it catches
Ask your AI assistant to run the Sentry. The Sentry then calls every check below and rewrites until the copy comes back clean. If you would rather see the findings first, the substance, hokiness, and AP Style checks each run on their own, and the full report shows all four verdicts, AI-tell scan included.
slop_sentryOne call checks your content for substance, hokiness, AI tells, and AP Style, then rewrites it until every pass reports CLEAN.
Every rewrite goes back through the checks, catching new issues introduced while the previous ones were fixed.
Standalone tools
Run a focused review, audit all four checks without changing the draft, or load the workflow instructions for your AI assistant.
substance_check Use it to find empty claims, unclear logic, contradictions, and broken connections. Six independent agents examine the draft; Slop Sentry fixes their flags, then a fresh agent checks the revision.
Included in the Sentry · Phase 1hokiness_check Use it when the draft feels forced, grandiose, or overly earnest. It reads the piece through either a social or professional-audience lens and shows your writing agent which lines to recast.
Included in the Sentry · Phase 2guard_sentry Use it for final cleanup of recognizable model habits. Code checks 400+ banned words and phrases and 30+ writing patterns, rewrites the flagged passages, and checks the draft again.
Included in the Sentry · Phase 3ap_style_check Use it to check and revise your draft for compliance with the 2026 AP Stylebook.
Included in the Sentry · Phase 4quality_check Use it when you want to see every finding before anything changes. It runs all four checks and returns one report with no rewrites.
Detection only · All four checksget_skill_procedure Use it to understand which Slop Sentry tools are available, what each one does, and how to use them.
Utility toolWhere the checks come from
Slop Sentry comes from ongoing observation and analysis of AI-assisted writing across articles, social posts, emails, proposals, press releases, guides, and more. The tool adapts its review to the format, applying different standards where the writing calls for them, and its checks keep evolving as new patterns emerge.
More than a blocklist
Slop Sentry combines precise, code-based checks with editorial judgment — over 400 checks that pattern lists and one-shot prompts cannot enforce reliably.
Setup
Two minutes of setup, no code required. Paste one snippet into your AI assistant's settings, restart it, and the tools appear. The guide walks through every step.

Developers on your team can run the same checks from the command line, inside scripts, publishing pipelines,
and text editors. Teams without a developer can paste our SKILL.md rulebook straight into an AI
assistant's instructions instead.
Questions
A prompt relies on a model to follow every instruction. The longer your instructions get, the harder it becomes for the model to retain them all.
Slop Sentry runs over 400 checks across the entire skill. Code enforces exact rules for banned language and structural patterns. Separate engines reserve LLM judgment for substance, hokiness, and AP Style — the questions a pattern list cannot answer.
It also keeps going. A prompt typically produces one rewrite, and that rewrite can remove one AI tell while introducing another. Slop Sentry sends the revised draft back through its checks so it can catch new problems as they appear.
Its detector library is maintained and expanded as new AI writing habits emerge. You get the updated checks without rebuilding your prompt every time the models develop another recognizable pattern.
In addition, typical writing cleaners focus on surface-level AI tells. Slop Sentry starts earlier by asking whether the draft says anything meaningful, contradicts itself, or slips into hokey language. There is little value in polishing the wording when the underlying point is empty or unclear.
Slop Sentry targets identifiable writing problems instead of imposing one house style. Its rewrites are instructed to preserve the draft's meaning and voice while removing the flagged language. Enterprise plans can also include custom brand voice profiles.
The rewrite instructions preserve names, numbers, quotes, facts, and the writer's intended point. Substance Check also looks for contradictions inside the draft. Any AI rewrite still deserves human review, especially when the wording has been legally approved or depends on specialized subject-matter expertise.
You can run the full Sentry and receive a revised draft, call any check on its own, or request a detection-only report that changes nothing. The original draft and the results stay visible in your AI conversation, so you can review, reject, or revise any change.
Slop Sentry adapts its checks for articles, blog posts, LinkedIn posts, emails, proposals, presentations, guides, press releases, image copy, and general business writing. Choose the format when you run it so the rules match the way that piece is supposed to read.
We never use your content to train models, and text is encrypted in transit. During beta, select execution details, including query text, may be logged temporarily to verify quality and reliability. We plan to eliminate content logging after beta. Do not send material that your policies prohibit third-party AI services from processing.
The AP Style check operates with 98.2% accuracy across 198 independent test runs. The AI-tell guard combines exact code-based matches with contextual judgment, while Substance and Hokiness evaluate questions that do not have one objectively correct answer. Use the detection-only report when you want to review every finding first.
Add it to Claude, ChatGPT, Suits.ai, or another MCP-compatible assistant, then ask that assistant to run Slop Sentry on a draft. The findings and revision come back in the same conversation. Setup does not require a developer; the guide walks through the connection step by step.
