Free tools
Tools that run on Jev, free and without an account. Each one shows a thing Jev is good at, so you can see it work before you build with it.
AI Slop Detector
Paste a URL. It screenshots the page, checks 34 tells of AI-generated design and copy, and gives you a slop probability you can share.
What Jev does: Jev answers 35 yes/no questions about the page in one call and returns a probability for each.
AI Writing Checker
Paste your text. It checks 12 AI writing patterns, quotes each one it finds, and gives you a score for how much it sounds like AI.
What Jev does: Jev answers 13 yes/no questions about the text in one call and returns a probability for each.
Meta Description Checker
Paste a title and meta description. It measures the pixel width Google cuts at, then Jev judges whether a searcher would click it and what is weak.
What Jev does: Jev answers a handful of yes/no questions about the title and description, including whether a searcher would pick it, and returns a probability for each.
Prompt Injection Tester
Paste a prompt, web page or tool result. It finds known injection patterns, quotes each one, and Jev scores how likely the text is an attack on a model that reads it.
What Jev does: Jev answers a dozen yes/no questions about the text in one call and returns a probability for each, the guardrail pattern at a fraction of a cent.
LLM Cost Calculator
Enter calls a day and tokens per call. See the monthly cost on 10 models from vendor list prices, with Jev, which bills input only, in the list.
What Jev does: Nothing: this one is plain arithmetic on published prices. It shows what Jev's input-only billing does to a bill.
