the problems

how blu solves them

you pay for 3 ai subscriptions and don't use all of them.
blu is 1 chat app that holds every model inside. bring your subscriptions, your api keys, and your local ai models.
none of them tell you what a single prompt costs.
every reply ends with its exact price, or the word free.
everything you type gets sent to someone else's server.
everything is stored locally on your computer — you own your data.
switching models means starting the conversation over.
swap models mid-chat — the old model writes the new one a handoff.

straight answers.

is it really free?

the app is free, full stop. later, the marketplace will sell optional add-ons — the app itself never charges you.

does my Claude or ChatGPT subscription work here?

yes. connect the subscription you already pay for and blu uses it directly — no second bill, no markup.

is my data actually local?

your chats, settings and files live on your Mac. we can't control what cloud models do with what you send them — but with blu, your data is 100% yours to own. local models send nothing anywhere.

how is blu free?

we believe ai tools should be for everyone. blu's basic version of the app is free…forever. if you like, you're welcome to purchase additional features in the marketplace (coming soon).

coming soon
