The useful difference is where the work happens
Both products start with an idea. The important question is what happens next. A hosted builder can move quickly toward a live service, but it also introduces accounts, online dependencies and a larger jump from prompt to production. Palm keeps the early work close: define the audience, narrow the first version, write the promise, and decide what should be built before you spend time wiring it together.
Palm
Local-first Mac workflow, product brief, launch assets, positioning and next actions. Useful when the idea is still moving.
Polsia
Hosted AI product workflow for founders who want an online system to continue building and operating the product.
Which should you use first?
Start with Palm if you have a rough idea, several possible audiences or a concern about handing early notes to another hosted service. Start with a hosted builder when your scope is already clear and you want to test a deployed experience immediately. They are not mutually exclusive: a good Palm brief can become the input for any later build.
A calmer first step
Write one sentence that names the user, the recurring problem and the smallest useful outcome. Palm turns that sentence into a practical brief, a launch angle and a short list of decisions. That makes the next tool more effective because you are no longer asking it to invent the product and the plan at the same time.
If you want an idea-to-app workflow that begins privately on a Mac, download Palm and make the brief before you make the build.
