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.
Data you can return to
Keep bookmarks, books or project details in managed app data. Find records and update them from a conversation.
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.”
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.
Make it yours
Review the screens, fields, tools and access requirements. Refine the app in the visual builder, manually or with AI assistance.
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.”
Where we are today
Useful by design.
Honest about early access.
Free accounts and manual app creation are open. AI assistance is activated by invitation, with a focus on supported apps using KernelApps-managed data.
External integrations depend on supported capabilities. Bring your own ChatGPT or Claude account. Manual editing does not use creator-AI credit.

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.
