Is Floati Browser free?

Yes. Floati Browser is free to download and use for macOS, with no account and no subscription.

What does it mean that the browser remembers what you read?

Floati keeps a full-text index of the pages you read entirely on your own device. You can search everything you have read and ask questions that are answered from those pages, with every source cited. Nothing is uploaded.

Yes. There are no accounts and no telemetry. Your memory, your reading and the AI that answers your questions all run on your own machine, so your browsing never leaves your device.

Which platforms are supported?

Floati Browser ships a signed, notarized universal build for macOS that runs on both Apple Silicon and Intel Macs.

The private, on-device answer to AI browsers

A browser that remembers your workday, not your data.

It runs entirely on your machine. No cloud, no accounts, no telemetry. Every page you read joins a private, searchable memory on your device, and you can ask questions of it and get answers with sources. Underneath sits a rendering engine written from scratch in Rust.

Coming soon for macOS and Windows. Free, no account, no sign-in.

The engine

Its own engine, written from scratch

Every cell is one piece of a web engine. Dark cells are built, half cells are underway, empty cells are still ahead. It is the complete list, not the flattering one.

★The reference browser parity, on our own engine

v0.1.0 - 0.1.9v0.1.355

Drag along the releases to see the engine at that moment. Each feature lights up in the release that started it and the release that finished it; recent releases also light every feature they worked on. A cell opens the release notes of the release that built it.

What it has

Its own HTML parser, CSS cascade, layout and paint. All four score 100 on the public scorecard.
A JavaScript machine with a tiered compiler. Hot loops become native machine code. Language and speed both at 100.
A network stack down to QUIC. HTTP/3 on by default, cookies and the public suffix list done by the standard.
Every royalty-free decoder. JPEG, WebP, AVIF, GIF, MP3, FLAC, Opus, Vorbis, VP8, VP9 and AV1, all written here.
A PDF viewer, an accessibility tree and a tracker detector, on device.

Where it is already better

No unsafe code in the parts that touch the web. The parsers, every decoder, the network stack and the PDF viewer are written without a single unsafe line. The reference browser decodes your images and video in C.
No ad auction. The in-browser ad targeting interfaces are declined by design, not switched off. Third-party cookies are partitioned and script cookies live seven days.
It remembers as it paints. Because the engine draws the page itself, every word is indexed as it is drawn and the page is kept as read. No bolt-on can do that.
Measured, not asserted. Every release is scored page by page against the reference browser. The typical page is within four percent.

Where it is going

Now, through 2026Reading-grade sites, faithfully. Where it is today.
Late 2027 into 2028Daily-driver beta. Most sites with no felt difference, scripts fast enough to use.
2029 to 2032A production default. Process isolation, a GPU compositor, developer tools, an extension model.
No fixed dateFull parity. Approached, never finished. No independent engine has reached it.

What leaves your machine

Collected, only if you opt in

A random install id (not tied to you)
The app version and your operating system name
A handful of anonymous counters: tabs, suspends, trackers blocked, memory saved, projects

Never collected

The pages you visit or anything you search
Your history, bookmarks, passwords or saved reading
Anything that identifies you. The exact payload is readable in browser/shell/src-tauri/src

The browser behaving the way you always assumed browsers did

Free. No account, no setup, no sign-in. It is not open to the public yet: join the waitlist and you will be the first to know the day it opens, for macOS and Windows.
