The panel appears over the app you are in, focused and ready. Nothing moves behind it. Record any other combination you like, in the first run window or in Settings.
For macOS · bring your own key
An AI panel, one keystroke away.
It opens over whatever you are doing, answers, and gets out of the way. You bring your own API key, so you pay the model provider directly: no subscription, no markup, no account.
Then €6.99, once. macOS 26 or later · Apple silicon · signed and notarized by Apple
The panel over the app you were in. Answers stream as they arrive.
The gesture
Three keys, and you are back to work.
No window to switch to, no tab to find, nothing left open behind you.
01
⇧Space
02
Type, then ↩
The answer streams in as markdown: headings, lists, code with a copy button. Press esc to stop it mid sentence, or ask a follow up.
03
⌘↩
The answer goes straight back into the app you came from, at the cursor you left. Or ⌘⇧C to copy it and leave.
Your key
Your models, your money.
Lume never sees a token. Every question goes from your Mac straight to the provider you chose.
No middleman, by construction
Most AI utilities resell you someone else's tokens at a monthly price, whether you asked anything that month or not. You paste an API key once, it goes into the macOS Keychain, and the bill is between you and the provider: itemised, and it stops when you stop asking.
One key, four hundred models
An OpenRouter key reaches Claude, GPT, Gemini, Grok, Llama, DeepSeek and Qwen. Or point Lume directly at Anthropic, OpenAI, or Ollama on your own machine, where a question costs nothing and never leaves the laptop.
Type / for the instructions you repeat. Each one can pin its own model: something fast to fix a sentence, something that thinks to explain a problem. Lume shows every model's price per million tokens, and how quickly it answers, while you pick.
What it does
Everything, for seven euros.
There is no other tier, and the trial is the whole app.
Quick prompts
Save the instructions you type again and again, fire one with /, then just paste the text. It stays attached to the follow ups until you take it off.
A model per prompt
Correcting a sentence and explaining a bug do not want the same model. Each saved prompt can pin its own, and the panel shows which one is about to run.
Web search, when it earns it
Switch search on for one question or for a saved prompt. Sources come back as small numbered pills, in place, and they are clickable.
The real model catalogue
Read live from the provider, not a list somebody typed once. Tick the handful you want in ⌘K and search the rest when you need them.
The key stays in the Keychain
Never in a config file, never on a server of ours, because there is no server of ours. There is no account to make, and what you type is never sent anywhere except to the provider you picked.
Works with no network at all
Point it at a local Ollama model and the whole thing runs on your Mac: no key, no bill, nothing leaving the machine.
Native, and light
SwiftUI and AppKit, no Electron, no bundled browser. Two megabytes, opens instantly, and does nothing at all while you are not using it.
Updates arrive on their own
Lume looks for a new version once a day and installs it when you quit. Every update is signed, and the checking has its own switch in Settings.
Signed and notarized
Developer ID signature with the notarization ticket stapled, so it opens like any other Mac app. The Accessibility permission is optional and only for pasting back.

FAQ
Questions people actually ask.
Is this an alternative to Raycast Quick AI?
It does the same job: one shortcut, a panel over everything, an answer you can paste back where you were. What differs is what you pay for. Quick AI sits inside a subscription that bundles the models with the app; Lume is bought once and asks for your own API key, so the model bill is yours, it is itemised, and it stops when you stop asking.
Do I need an API key, and what does it cost?
Yes, one key from a provider you choose. OpenRouter is the easiest, because a single key reaches more than four hundred models; Anthropic and OpenAI keys work directly too. Pricing is per token and public, and Lume prints the price per million tokens next to every model while you pick one. A short rewrite on a fast model costs a small fraction of a cent, so ordinary daily use lands in the low single digits of euros a month.
Can I use it without paying any provider?
Yes, with Ollama. Run a model on your own machine and Lume talks to it over localhost: no key, no network, no cost. Local models are slower and less capable than the hosted ones, but for rewriting and summarising they hold up well.
Which models can I use?
Whatever your provider offers, read from their live catalogue rather than a list hardcoded into the app. Through OpenRouter that means Claude, GPT, Gemini, Grok, Llama, DeepSeek, Qwen, Mistral and several hundred more, including the free tiers. You tick the ones you actually want to see, and search the rest when you need them.
Does Lume send my data anywhere?
What you type goes to one place only: the provider you configured. There is no Lume account, no server of ours in the middle, and your key lives in the macOS Keychain. The app does send anonymous usage counts, so we can tell whether people get past the first run: which provider is selected, how many questions have been asked, whether a licence was activated. Never your questions, the answers, or anything you paste. It is one switch in Settings, and turning it off stops it completely.
What do I need to run it?
macOS 26 (Tahoe) or later on an Apple silicon Mac. The app is signed with a Developer ID and notarized by Apple, so it opens normally with no Gatekeeper warning. The Accessibility permission is optional: it is needed only for ⌘↩, which types the answer back into the previous app. Without it the answer is still copied for you.
Does it speak my language?
The interface is in English and Italian, and follows your Mac. The answers come back in whatever language you asked the question in, because that is what the app tells the model to do.
Is there a subscription, or a trial?
No subscription: €6.99 once, updates included. Download it and the first 15 questions are free, with nothing switched off and no card asked for. After that Lume asks for a licence key, which arrives by email as soon as you buy one.
