Lume

An AI panel for your Mac, 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.

The Lume panel open above the desktop, rewriting a paragraph of an email in streaming text

The panel over the app you were in. Answers stream as they arrive.

Three keys, and you are back to work.

01 Space

The panel appears over the app you are in, focused and ready. No window switch, no dock icon, nothing moves behind it. Record any other combination you like, in the first run window or in Settings.

02 Type, then ↩

The answer streams in as markdown: headings, lists, code with a copy button. Press 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 to leave.

Your key, your models, your money.

Most AI utilities resell you someone else's tokens at a monthly price, whether you asked anything that month or not. Lume never sees a token. You paste an API key once, it goes into the macOS Keychain, and every question travels straight from your Mac to the provider you chose.

One OpenRouter key reaches more than four hundred models: Claude, GPT, Gemini, Grok, Llama, DeepSeek, Qwen. Or point Lume directly at Anthropic, OpenAI, or Ollama on your own machine, where a question costs nothing and never leaves the laptop.

Typing a slash in Lume lists the saved prompts: Fix, In English, Summarise, Explain

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 you get for seven euros.

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. Nothing is logged, nothing is counted, there is no account to make.

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 small

SwiftUI and AppKit, no Electron, no bundled browser. Under a megabyte, opens instantly, and does nothing at all while you are not using it.

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.

15 questions, no card, no account. Buy a licence when you want to keep going.

  • The trial is the whole app, not a cut-down one.
  • Every feature. There is no other tier.
  • Updates included.
  • Use it on the Macs you own.
  • No account, no telemetry, no server.
  • Model costs go to your provider, never to us.

The licence key arrives by email; you paste it into Settings once. It needs macOS 26 (Tahoe) or later on Apple silicon, and an API key from a provider of your choice.

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?
Only to the provider you configured, and only what you type. There is no Lume account, no analytics, no crash reporting and nothing in the middle: your key lives in the macOS Keychain and the app talks to one endpoint, the one you chose.
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.
