One of the small but useful things I tested in DIA is its custom skills feature. It is easy to overlook because it is not a separate app or a complicated automation system. In practice, a skill is basically a reusable prompt.
If you find yourself typing the same AI instruction over and over, DIA lets you save that instruction and call it back with a slash command.
Quick Answer
In DIA, a custom AI skill is a saved prompt. You create it from the slash menu, give it a name, and then reuse it later by typing slash and selecting the skill.
For example, I created a simple test skill called “summarize with bullet points.” After saving it, I could open the slash menu again, pick that skill, and DIA would apply that prompt to the current task.
What A DIA Skill Does
The simplest way to think about a DIA skill is this: it is a prompt shortcut.
Instead of rewriting an instruction every time, you save the instruction once and reuse it when you need it. That makes sense for anything you do repeatedly, like summarizing pages, drafting replies, cleaning up text, or using a specific writing format.
How I Created One
In the test, I typed slash inside DIA, which opened the skills window. From there, I clicked into the skill creation flow and named a new skill “test summarize with bullet points.”
That created the skill, and it then appeared alongside other saved skills I already had, including things like a YouTube reply prompt, a normal summary prompt, and job copy prompts.
- Type slash in DIA to open the skill menu.
- Create a new skill from that window.
- Name the skill based on what it does.
- Save the prompt so it can be reused later.
Using The Skill Later
Once the skill was created, I went back to the slash menu and could see the new test skill listed there. Selecting it applied the saved prompt and gave me the output in bullet points.
That is the practical value here. The feature is not about doing something wildly complicated. It is about reducing repeated typing and keeping your common AI instructions consistent.
Recent Skills Are Easier To Reach
One detail I noticed is that DIA keeps your most recently used skills accessible near the top. When I opened a new tab, the last couple of skills I had used were still surfaced there.
That matters if you rely on the same few prompts throughout the day. You do not have to dig around every time you want to reuse them.
Where This Is Useful
The examples I had in DIA were everyday workflow prompts: YouTube replies, summaries, and job copy. Those are exactly the kinds of things that make sense as skills because they have repeatable structure.
This is still a basic use case, but it shows the direction. DIA’s skills can help if you already know the prompts you reach for often and want a faster way to run them inside the browser.
- Summarizing web pages or notes into bullet points.
- Drafting repeatable response formats.
- Reusing a standard writing style or structure.
- Keeping common prompts available across browser work.
Key Takeaways
- A DIA skill is essentially a saved AI prompt.
- You can create and trigger skills from the slash menu.
- Skills are useful for repeated tasks like summaries, replies, and structured writing.
- Recently used skills appear where they are easier to access again.
- The feature is simple, but practical if you use the same prompts often.
