Can My Product Become One of Doraemon's Gadgets?

Lately I've been thinking about whether my product can become one of the secret gadgets inside Doraemon's fourth-dimensional pocket.

When Nobita comes crying "I wish I had one of those," Doraemon pulls a gadget out of his fourth-dimensional pocket. Want to fly? The Takecopter. Want to shrink? The Small Light. Nobita touches tools through Doraemon, and uses them with him.

Doraemon, here, is Claude Code. Claude Code is no longer just an assistant that writes code. Wielding all kinds of gadgets, it researches, designs, writes, plans trips, shops, runs businesses — it assists with, or simply does, everything. It has become something like Doraemon.

Nobita = the customer
Doraemon = AI agents like Claude Code and Codex
The fourth-dimensional pocket = the ecosystem of MCP, CLIs, and skills that connects agents to services
Secret gadgets = services made agent-ready through that ecosystem

If that's the mapping, then the question every product we build now faces is whether it can become one of Doraemon's gadgets.

Service as a secret gadget

Figma had been building its own agent, Figma Make — and just recently, Figma became operable from agents like Claude Code. It became one of Doraemon's gadgets.

Even before Figma, some services were born as gadgets from day one — AI-native from the start. Design tools like Pencil. Video tools like Remotion, markdown editors like Proof. There seem to be plenty of services you can already drive from Claude Code.

For more obvious examples: Ramp started offering credit cards for agents, and there's a YC startup making email for agents. Now that Claude Code and Codex have become Doraemon, all kinds of services have started supplying him with gadgets.

Offering your service as a gadget inside the ecosystem of Doraemon's pocket — the so-called "to-A," to-agent market — is starting to accelerate.

Nobita only uses Doraemon's gadgets

Until a little while ago, most products were building "their own agent." I'm not sure that's the right name for it, but they were, so to speak, Doraemons without the pocket — services carrying only a handful of their own gadgets.

From the user's side, though, the in-house agent is starting to feel like a chore. I think it's the same thing as not being able to leave the chat AI you've always used because your context has piled up there.

With chat AI, if you'd been using ChatGPT, your context accumulated in it, and that context itself was the switching cost. But with Claude Code versus somebody's in-house Doraemon, it's not just context anymore — the breadth of the gadgets becomes the comparison. There's a Doraemon at Nobita's house; walking somewhere else to ask a different agent is a hassle. And that agent doesn't carry anywhere near as many tools as Doraemon does.

I suspect Figma moved to support Claude Code, and not just Figma Make, because it judged that being one of Doraemon's gadgets is stronger than being a Doraemon.

"I wish I could fly."
"Here — Takecopter!"

That world is becoming real.

Even today, plenty of people ask ChatGPT "what's the best design tool?" One step further, and you don't just get an answer — Doraemon hands you the gadget itself. The recommendation doesn't end as a recommendation; it arrives in your hands as a tool.

As that happens, Nobita will almost never touch a service Doraemon can't handle. A tool Doraemon can't produce may as well not exist, as far as Nobita is concerned.

Services that didn't make it into the pocket disappear from Nobita's options. And services that are in the pocket may get used more than ever before.

Doraemon can find it, use it, and use it together with Nobita. Maybe that's what "service as a secret gadget" means.

Can we become one of Doraemon's gadgets?

I run a startup myself, and lately this is what I keep turning over as I build.

I've written this around Claude Code, but the same goes for Codex — and maybe OpenClaw, even Poke. Doraemons with fourth-dimensional pockets of their own are being born: Dorami, Noramyako, Dora the Kid.

Can our service become a gadget for the Doraemons?

If it's in the pocket, Doraemon might hand it to Nobita and use it alongside him. If it's not, it may never catch Nobita's eye at all. The more Doraemon becomes infrastructure, the wider this gap grows.

To set out on the great adventure with Nobita, the first thing that matters is getting into the pocket.
