Less setup. More useful.

An app is more than
a clever answer.

Give your conversations somewhere to keep information—and something useful to do with it.

01

A screen when you need one

Browse a list, review a record or work with a form. Bring an interactive interface into compatible chat hosts.

02

Data you can return to

Keep bookmarks, books or project details in managed app data. Find records and update them from a conversation.

03

Room to change your mind

Refine screens and tools as your needs change. Review versions, update a release and return to an earlier version when needed.

The build → use → update loop

From “I wish I had…”
to “open my app.”

1

Describe something useful

Start with a focused idea: a reading list, a project tracker or a place to save links. KernelApps prepares a supported app around managed data.

2

Make it yours

Review the screens, fields, tools and access requirements. Refine the app in the visual builder, manually or with AI assistance.

3

Connect and keep improving

Connect a private release in ChatGPT or Claude using the host’s setup flow. Prepare later changes as versions and review them before updating.

Each host has its own setup and account requirements. Private connections are separate from public marketplace listings, which follow the host’s review process.

Start with something you’ll use

Your everyday ideas.
A place to live.

Focused tools for a real routine. Here are a few examples of apps built around managed records.

Bookmarks

A home for saved links

Save useful pages, organize your collection and find the right link again.

“Show my saved design resources.”
Reading shelf

Your next great read

Keep a reading list and update what you’re reading, finishing or saving for later.

“What’s on my reading list?”
Projects & tasks

A clear next step

Give tasks a project, track progress and return to the details that matter.

“Show the tasks for my launch.”

Before you start

A few practical details.

What can I build today?

Early access focuses on supported apps backed by KernelApps-managed data, such as lists, records and project tracking. Arbitrary external APIs and integrations are not a universal self-service feature.

Does a private connection publish my app publicly?

No. You connect privately in each host using its own setup flow and required account access. Public marketplace listings require a separate host submission and review.

What does the AI allowance cover?

AI assistance for creating and editing your app inside KernelApps. It does not pay for conversations in ChatGPT or Claude. Manual editing does not use creator-AI credit.
