Private AI for Reading Sensitive Documents at Home

If you want AI help with a sensitive document, the safest option is one that runs on your own computer. With Hearth, you can ask questions about private files without sending them to someone else's computer, rented.

What kind of documents are we talking about?

A lot of everyday reading is more personal than it looks. You might want help understanding:

a lease or rental addendum
an insurance letter
a benefits notice
a school form
a medical bill
a contract from a freelancer or client
a long policy or handbook

These are the kinds of documents people often want translated into plain English. Not because they are secret in a dramatic way, but because they are annoying, confusing, or stressful.

Hearth is useful here because it gives you a warm light in a cold cloud: a private place to ask, “What does this mean?” without uploading the file to a service you do not control.

Why not just use a cloud AI?

Big cloud AI tools are great for lots of things, and they can be especially helpful for huge projects or work that needs powerful coordination. But if the document is personal, local AI has a simple advantage: it stays on your machine.

That means:

no account to create
no subscription to manage
no file upload to someone else's computer
no need to worry about whether you remembered to delete a chat later
no internet required after setup

For a lot of people, that makes the experience feel calmer. You can think out loud, ask follow-up questions, and keep going without wondering where your document went.

How Hearth helps with a private document

With Hearth, you can open a document and use AI to make it easier to understand. A few useful prompts might be:

“Summarize this in plain English.”
“What are the main obligations here?”
“What deadlines should I notice?”
“Which parts look important to read twice?”
“Explain this like I’m 12.”
“What questions should I ask before I sign?”

That last one is especially helpful. Hearth is not a lawyer or doctor, but it can help you get oriented before you talk to the right person.

If you want to try it, the simplest place to start is the Hearth app.

What makes local AI a good fit for documents?

When you're reading something sensitive, the value is not just privacy. It's also focus.

Local AI works well because it lets you stay close to the original text. You can ask small, specific questions and get answers right away. You do not have to copy pieces into a web form, juggle tabs, or worry about whether a browser-based tool is quietly storing your content somewhere.

It is a bit like downloading a movie for a flight instead of streaming it. You get the thing you need onto your own device, and then it is there when you want it.

That makes Hearth handy for:

spotting key dates and terms
translating legal-ish language into normal language
comparing two versions of the same document
pulling out action items
making a long page feel less overwhelming

A few good ways to use it safely

Even with private AI, it helps to be thoughtful.

Use it to understand, not to replace expert advice.
Ask for summaries before asking for conclusions.
Double-check anything important in the original document.
Keep the file on your own computer if you want the whole process to stay local.
If you need a bigger model for a tougher task, Hearth also has a desktop app.

If you want a quick overview of how Hearth handles privacy and local use, the FAQ is a good place to look.

Who is this especially good for?

This is a great fit if you are the kind of person who:

feels stuck when reading dense paperwork
wants help understanding a form before acting on it
does not want to paste personal documents into a cloud tool
prefers to work quietly offline
wants AI help without making an account

It is also nice for people who simply like having a second set of eyes. Sometimes the hardest part is not the document itself. It is the mental friction of starting.

What Hearth is, in one sentence

Hearth is a free private AI chat app that runs on your own computer, so you can ask questions about sensitive documents without sending them anywhere else.

If that sounds useful, you can try it and see how it feels on your own machine.
