You need a small tool for one task, but setting up a web project would take longer than using it. OGAD (Off Grid AI Desktop) can generate an HTML app with a local model and show it beside the chat. Ask for a self-contained file, test it, and download a copy that can run without internet.

A packing checklist, unit converter, or small tracker is a useful starting point. The goal is one working interaction you can inspect, not a production service with accounts and a database.
What can you make without a cloud coding service?
OGAD can preview generated HTML with its CSS and JavaScript. A local text model writes the code, while the canvas shows the result. This is a free core feature on supported Mac and Windows computers.
Download a model suited to coding that fits your computer. Finish that setup before disconnecting. The model's skill matters: a local model can produce invalid code, so plan to test and revise the result.
A self-contained app uses code and assets inside the file. Ask for no external libraries, web fonts, remote images, or network requests. Local code generation alone does not make a page's dependencies offline.
Start with one useful action
For example, a packing checklist needs an input, an Add button, and a way to mark items done. Describe that behavior before asking for visual polish.
Build a packing checklist as one complete HTML file with inline CSS and JavaScript. Let me add an item, mark it done, and remove it. Include a clear empty state. Use no external dependencies or network calls. Return one fenced html code block. Do not add accounts or claim that data is saved between sessions.
That last sentence keeps the first version simple. Persistent storage can be a separate, deliberate change after the basic interaction works.
How do you get the first version running?
- Select a downloaded local model in Models > Text.
- Start a chat and send the small app request.
- Open the generated artifact card, or use the reply menu's Open canvas action.
- In Preview, add a sample item and try each control.
- Use Code to inspect the generated source. Ask for a specific correction in the same conversation if needed.
The expected result is a working page in the canvas. The released canvas recognizes HTML code blocks and provides Preview, Code, and Download controls.
What should you test before keeping it?
Try a normal item, an empty input, and a long label. Check that removing one item does not remove another. Refresh or reopen the page so you understand whether its current data lasts only for the session.
Describe a failure precisely:
When I add an empty item, it creates a blank row. Prevent blank items and keep the other behavior unchanged. Return the complete updated HTML file.
Save a working version before a large revision. Asking for one change makes it easier to see what broke.
Turn the first version into a tool you will reuse
Once the checklist works, use it for one actual packing task. Add the items you would otherwise put in a note. Mark a few done, remove an item you no longer need, and check whether the remaining list still makes sense.
That exercise tells you which improvement matters. You might need a count of unfinished items or a way to clear completed items. Ask for the change that solves the real friction instead of adding several features because the model can generate them.
For example:
Add a count of unfinished items above the list. Update it after Add, Done, and Remove. Keep all existing input checks. Do not add storage or external libraries. Return the complete updated file.
Afterward, add two items, mark one done, and remove the other. Check the displayed count against the actual list. This is a simple acceptance check you can perform without treating the model's claim of success as evidence.
Choose how much complexity the small tool needs
The one-file approach is useful when input, behavior, and output fit in the browser. It keeps the first working result close to the conversation where you described it.
| Need | Useful first choice |
|---|---|
| A checklist for one session | Keep data in the current page and label the session limit |
| A repeated calculation | Supply the formula and several known answers |
| A screen to discuss with a colleague | Use sample data and clearly label the prototype |
| Shared accounts or live records | Plan a separate backend instead of pretending the file supplies one |
If you later request browser storage, make that a separate change with explicit save, reload, and reset behavior. Test it in the downloaded page too. Storage behavior in a preview is not proof of how the exported file will behave in every browser.
Keep the simple version until the more complex one passes the same checks. You then have a usable tool even if the next experiment fails.
How do you keep an offline copy?
Select Download in the canvas to save the HTML file. Open that file in a browser and repeat the basic checks with internet access off. This checks the exported page as well as the in-app preview.
A page that needs a server, external API, or remote asset will not become independent just because it has an HTML extension. For your first tool, keep everything in the file and use ordinary browser features.
Get OGAD, describe one small tool, and test its main action. Download it once that action works.
