ON THE EVERYDAY

The art of
paying attention.

There is a particular kind of quiet that arrives when we give something our full attention.

We begin to see what was there all along: the small details, the connections, the space between one idea and the next.

Reading is an invitation to slow down. To follow a thought a little further. To leave room for something unexpected.

Good ideas need
a little breathing room.

01 / A SPACE OF YOUR OWN

For the words you read.
And the ideas you keep.

A research paper. A favorite book. That document you finally have time for. Give it a workspace that feels right.

01

Settle into the page.

Nine page themes, adjustable Flow text, a reading ruler, and focus mode. Make a little comfort your default.

02

Keep the thread.

Highlight a passage, leave a note, or connect ideas on a canvas. Your thoughts keep a path back to the source.

03

Stay in your own space.

Native Windows reading, without an account or analytics SDK. Choose temporary reading or save your place and notes locally.

A SMALL REMINDER

The best part of reading is what happens between the lines.

Make a little space for it.

02 / LESS EXPLAINING. MORE EXPLORING.

Make yourself at home.

A small taste of the reading experience.
Go on, change a few things.

A NOTE ON ATTENTION

CHAPTER ONE

The quiet joy
of noticing.

Some things only reveal themselves when we slow down. The way light falls across a room. A sentence that stays with us long after we turn the page.

Reading gives us a place to practice this kind of attention. Not to finish something, but to find something. A new perspective. A familiar feeling, put into words for the first time.

So take your time. Underline the thought. Follow the footnote. There is no hurry here.

A FEW THINGS, BEFORE YOU SETTLE IN

Good to know.

What can I read with COGNIV?

PDFs and supported DRM-free, reflowable EPUBs. Fixed-layout EPUB and DOCX viewing are not available in this preview. Complex PDF layouts may need the original page view rather than extracted Flow text.

Is it free? Do I need an account?

COGNIV is free and open source under AGPL-3.0-only. The desktop app does not require an account and includes no analytics SDK.

What stays on my computer?

The desktop reading workspace uses local documents. You choose temporary reading or retention of your place, notes, and history. Saved reading records use encrypted local storage. Temporary reading is not a zero-trace guarantee: deliberate exports, clipboard contents, and Windows-managed data have separate lifecycles. This homepage is hosted online by Cloudflare.

Does it include AI?

An optional local assistant is available in the desktop preview. It starts disabled and includes no model or runtime. You must select compatible offline files separately, and explicitly choose the excerpt to share with the local model. Answers can be wrong; check the source.

Can I install it today?

The current version is 0.5.1-preview.2, an unsigned engineering preview. A public installer has not yet been approved or linked here. When a reviewed release is available, the download area will offer Windows Setup and Portable options.
