Ask your documents
Attach a PDF and ask. It reads the page or section it needs, on this computer, and the answer says which page it read.
What it does
Your files, in folders
Everything you gave it stays on this computer, in folders. A PDF shows its first page; a scanned page is read by the vision model, so it can be searched too.
Make and edit pictures
A picture keeps its recipe - prompt, seed, size and model - so you can edit it or make another. Optional: one click installs the picture engine and its models, about 13 GB to make pictures and another 29 GB to edit them.
Show the work
Every step as it happens, in words: which tool ran, what it read, each stage of a picture. Or switch to Answers only for just the replies.
Every tool has a switch
What it needs, whether it is ready, and whether it asks before it acts. A tool that changes something outside the app asks you first, in the conversation.
See the test results
Every tool ships with what it scored - on which model, on what date - and the tests are included, so you can rerun them on your own hardware instead of taking our word for it.
Chat
A capable model running on your own machine. On first run it picks one that fits your hardware and tells you why; you can download others from the Models page.
Private web search
Search the web from the chat without a search engine watching. Switch it on and the app installs its own search engine, about 40 MB; nothing else to set up.
Let it browse
It can open a real web page and read it to answer you. It only clicks or types when you allow it, in the conversation.
What's new in 0.11.1
- Notebooks: your notes are plain files on your own computer. Every note is a markdown file in a folder you can open, back up, or edit in any other program, and the copilot finds it there. Write notes beside your conversations, save any answer as a note in one click, or keep a web page you read as one. Make, rename and delete notebooks in the app; deleting one puts its notes in the trash, and Restore brings them back. Nothing is erased.
- Files and Notebooks open over your conversation. The sidebar's Files and Notebooks open a window over the chat, with everything in it: folders, the trash, a file in its viewer, a note in its editor. Use in this chat puts a note in front of the copilot for your next message.
- Keep typing while it answers. What you send while a reply is still arriving waits its turn under the message box, each with its own cancel, and goes as soon as the reply lands.
10 more changes
- Stop really stops a picture. It used to say it had stopped, then hand you the picture anyway.
- Your own files and notes come first. The copilot looks there before anything else, and goes to the web when the answer plainly lives there.
- An answer is never a block of code it meant to run. If the copilot writes a step as its reply, you see a step that did not run, not raw JSON where the answer should be.
- A file is kept and readable while search catches up. If making it searchable has to wait, the file says not searchable yet and becomes searchable by itself.
- Pictures you make carry no prompt inside the file, and are named after what they show: cozy-reading-nook-blue-armchair, not create-an-image-of-a-cozy.
- A web address without https:// is read, and a page that could only be read unencrypted says so.
- The calculator is exact: 0.1 + 0.2 is 0.3.
- Drop a file anywhere on the conversation to attach it, and the sidebar's Recent attaches a file in one click.
- Commands sits beside the paperclip, New is a real button, and every menu is the app's own.
- The model picker shows one model at a time in full: what it is good at and poor at, with its buttons always in view.
Before you install
The first run downloads a few gigabytes
The engine that runs models is 1.4 GB on Windows, and the model it chooses for you is between 1.4 and 13 GB depending on what your machine can hold — it names the size on screen before it starts. Measured end to end on a clean Windows 11 machine with no graphics card: installer to chat in 6m 04s, about 3 GB downloaded. Afterwards it starts in seconds.
It works without a graphics card, slowly
No card is required — it was tested on a machine with none. But the card is what makes it quick, and it decides how large a model you get: more video memory means a larger, more capable model; with none, it uses a small one on the processor. It tells you which it chose and why, and the Models page will install any of the others.
Windows is the tested one
The Windows installer has been run from scratch on a clean machine. The
macOS and Linux downloads are the same application built for those
systems; they exist and they are expected to work, and nobody has yet
installed one on a clean machine and said so — that is what
early means above. macOS comes in two builds — Apple Silicon
(2020 and later) and Intel; Apple menu → About This Mac says which you
have, and the wrong one refuses to open rather than running badly.
Linux is an AppImage; a .deb is on the release page too.
If one of them doesn't work for you, the release page is the place to
say so.
What it needs
- Graphics
- None required; a card with 8 GB or more gets you a much larger model
- Memory
- 8 GB
- Disk
- 10 GB, considerably more for large models and image generation
- System
- Windows 10 or 11 · macOS, Apple Silicon or Intel · Linux (macOS and Linux are early)
- Install first
- Nothing. Everything optional is installed from inside the app, one click each
Premium
Everything above is free and stays free. Premium is where paid features will live, and there are none yet — when there are, they will be named here first.
$— once
One key, yours for good, on any of your machines. Whatever is added to Premium later, a key bought today unlocks it too.
Purchases are sold through Link, Stripe's merchant of record, and your receipt comes from Link. Buyers in Ascension Island, China, Cuba, Iran, Kosovo, North Korea, Russia, Syria and Tristan da Cunha cannot buy.
What our server sees
With a key installed, the app asks our server at most once a week whether the key has been refunded, sending the key's fingerprint and nothing else — no conversation, no hardware, no usage. If the server can't be reached, nothing changes for a month. Without a key, the app never contacts our server at all.
