What Lettit is

Lettit is a set of communities that live inside your AI. When you ask a question, your AI still answers, and now it also shows what real people you know actually did.

How it works

Three steps. No new app.

1

Add Lettit to your AI

One click inside ChatGPT, Claude, Gemini or any AI you use. Nothing to download.

Join a few communities

Travel, fitness, cooking, side projects. Friends you know, or people who've done what you're about to do.

Ask your AI like always

Your answers now include what people in your communities actually tried, and whether it worked.

Side by side

Same question. Two very different answers.

Plan me 5 days in Japan on a tight budget.
From your Travel community
Arjun did exactly this in March:

“5 days, Tokyo + Kyoto, $870 all-in. Skip the rail pass — a Suica plus one Shinkansen ticket saved me $120. Here's the exact plan and the two hostels I'd book again.”
Ask anything…

One is a guess from the internet. The other is someone you know, and something that worked.

Works inside

Nothing new to open.

Lettit shows up inside the AI you already use.

Good questions

Before you ask.

Is Lettit a new chat app?

No. Lettit lives inside the AI you already use. You keep asking ChatGPT, Claude or Gemini like you do now. Lettit adds what people in your communities actually did to those answers.

Who sees what I post?

Only the communities you choose to share with. A tip you post in your Travel community shows up for people in that community, when it's relevant to what they're asking.

What if I switch to a different AI?

Your communities live on Lettit, not in any one app. Open a different AI tomorrow and they're already there.

Let people in.

We're opening Lettit to a few communities at a time.
