Ran a 72-hour benchmark on SQLite WAL mode with 10M concurrent writes on an M3 Max NVMe. Throughput peaked at 48,200 ops/sec with p99 latency at 1.4ms.
Reproducible benchmark script and Flamegraph repo linked below.
Built on TypeSafe AI's System One model (founded by former OpenAI researchers). Pure calibrated decision-making without LLM latency or hallucination.
Flags low-value, formulaic posts with a bold rubber stamp and score pill right in your feed—so you recognize engagement fluff in a split-second.
Jev AI evaluates visible posts in milliseconds. Your feed scrolls at a buttery 120 FPS with zero lag or stuttering.

Set aggressive thresholds for LinkedIn corporate fables while keeping engineering and science discussions on X relaxed.
SlopAlert only analyzes public post text in active view. It has zero permissions to read private DMs, drafts, or keystrokes.
“Social feeds became readable again. It doesn't shout or block things—it just gives me back 45 minutes every day by exposing low-effort engagement bait before I dive in.”

Use your own Jev AI and use it for free.
The free tier is strictly for users who supply their own Jev AI API key from TypeSafe AI.
From developers, researchers, and writers who treat their attention as their most valuable asset.
“LinkedIn had become virtually unreadable with AI parables and hollow inspirational stories. SlopAlert's soft dimming instantly highlights the 3% of posts actually worth my time.”
“The reason drawer is what sold me. Most 'AI detectors' make vague, high-stakes accusations. SlopAlert objectively measures information density and recycled hooks. It's an attention tool, not a police badge.”
“I was skeptical until I saw it flag those cookie-cutter 'I spent 10 years learning X so you don't have to' threads while keeping real technical breakdown threads crystal clear. Brilliant execution.”
SlopAlert is powered by Jev AI from TypeSafe AI, founded by former OpenAI researchers. Unlike traditional LLMs that waste seconds generating conversational text, Jev is an ultra-fast 'System One' decision model that returns calibrated probabilities and classifications in 30–50 milliseconds. This enables real-time scoring as you scroll.
When Jev AI calculates a high probability of formulaic, low-density fluff, SlopAlert applies an animated red rubber stamp across the post along with a clear score badge (e.g., '• Slop | 79%'). You spot low-value content before spending time reading it.
SlopAlert works identically across X (Twitter), LinkedIn, Threads, and Reddit. Supported browsers include Google Chrome, Apple Safari, Mozilla Firefox, Brave, Arc, and Microsoft Edge.
Never. SlopAlert only evaluates public post elements visible within your browser viewport. It has zero permissions to inspect direct messages, drafts, compose boxes, or private feeds.
No. Because Jev AI delivers sub-50ms inference without large generative token streams, your browser maintains silky 120 FPS scrolling with negligible CPU overhead.
Yes. You can customize the slop score threshold (e.g., only stamp posts above 80% slop), switch to quiet badge-only mode, enable soft dimming, or auto-collapse posts based on your preference.
The Free Tier is exclusively for users who bring their own Jev AI API key from TypeSafe AI. If you use your own key, SlopAlert is 100% free forever with no usage limits or fees from us. If you prefer zero setup without managing an API key, our Monthly ($9/mo) and Lifetime ($99) plans include hosted cloud inference out-of-the-box.
Both plans include high-speed hosted Jev AI cloud inference with zero technical setup—no API key required. The Monthly plan is $9/month and can be canceled anytime. The Lifetime plan is a one-time payment of $99, granting permanent hosted access and all future updates with no recurring fees.
Instant real-time slop stamping powered by Jev AI. Filter out low-effort noise the moment it appears.
