I built a tool that explains any confusing document in plain words (your level, your language)

A developer built Plainly, a free AI tool that rewrites confusing documents—such as blood test results, legal letters, and insurance policies—into plain language at a chosen reading level and in the user's language. It also offers a RealCheck mode that analyzes suspicious messages for scam red flags. The tool uses a Python backend with a free LLM and a strict JSON contract for reliability.

A blood test full of abbreviations. A legal letter. A bank statement. A

government form. A dense insurance policy. To understand your own information

you often need a professional — which costs time and money.

So I built Plainly: paste any confusing text and get it back in plain language — at the reading level you choose (from "like I'm 10" to "keep it

precise") and in your language.

You get a TL;DR, key points, things to watch out for (deadlines, anything that

needs action), the hard words decoded, and practical next steps.

Paste a cryptic blood report like Hb 9.2 g/dL, MCV 72 fL, ferritin 8 ng/mL

and

it comes back with: "Your blood test shows anemia — low red blood cells — most

likely caused by not having enough iron," plus what each term means and what to

do next.

There's a second mode — RealCheck — where you paste a suspicious message or a

claim and it reasons calmly about whether it's plausible, calling out scam and

misinformation red flags (urgency, pay-a-fee, prize-you-didn't-enter, crypto doubling, verify-your-account links) and how to check it yourself.

It's an AI explainer/reasoner, not a doctor, lawyer or fact-checking oracle

great for understanding and for asking better questions, not a final authority.

Nothing is stored, no signup, free.

Under the hood it's a tiny Python (stdlib) backend forwarding to a free LLM, with

a strict "JSON only" contract + retries to keep responses reliable. What kind of

confusing document should I make it handle better?
