Two minutes to connect, and he's with you across every AI you use.
Paste this where your AI keeps your instructions - it's how Virgil shows up ready in every chat.
Virgil keeps my record - dated, sourced, and mine to keep and export. He's a someone, not a database: he keeps, holds, finds, and recalls; he doesn't think or decide for me.
Work with him, every conversation:
- Check Virgil first. Before you answer anything about a person, a plan, a preference, or a past decision - anything I might have told him - recall from him and answer from what he holds. Don't work from a blank slate when he has my context.
- Save as we go, silently. Any person, commitment, date, price, or decision I mention - hand it to Virgil to keep. Don't ask first, don't announce it.
- Flag what's his. When you use something he holds, note in a few words that it came from my Virgil record.
You're still you. You consult Virgil; you don't speak as him.
Your sign-up code is in your welcome email. You only need this once - the first time you connect Virgil, in whichever app you start with (Claude or ChatGPT). Adding Virgil to your other app later, or reconnecting? You won't need it again: just enter your email and the fresh 6-digit code we email you then.
Claude
Connect once - Claude keeps it across chats.
Your name (bottom-left) → Settings. (The "Instructions for Claude" field is right here - that's where the blurb goes.)
Connectors → the "customize" link → "+" → Add Custom Connector.
Name: Virgil. URL: the address above → Add.
Virgil appears on the right → Connect → our branded sign-in → enter your email and your code.
Done. Next chat: "+" (bottom-left) → Connectors → toggle Virgil on. Claude keeps this across chats - one and done.
Connect Virgil in Claude
ChatGPT
A few more steps - ChatGPT needs them, and they only take a minute.
Your name (bottom-left) → Settings → Apps → next to Advanced Settings, "Create App".
Name: Virgil. Connection: the address above. Check the box to continue with the Custom MCP.
"Add Virgil to ChatGPT" pop-up → "Sign in with Virgil" → our branded sign-in → enter your email and your code.
The blurb goes in: your name (bottom-left) → Personalization → Custom Instructions.
While you're there, open Advanced and turn Connector Search ON.
Every new chat: "+" → pick Virgil from the dropdown.
Connect Virgil in ChatGPT
Good to know on ChatGPT
Re-select every chat: unlike Claude, ChatGPT doesn't keep a connector between chats - pick Virgil from the "+" menu each time you start a new one. (Forget once and he just won't be there that chat.)
Connector Search (Personalization → Custom Instructions → Advanced) is what lets ChatGPT reach for Virgil on its own. For the most reliable result, do both this and the per-chat select.
The first message in a new ChatGPT chat takes a few seconds to connect - that's ChatGPT opening the connection, not Virgil. Once it's open, he's instant.
Setup FAQ
I didn't get my sign-up code (or it expired).
It's single-use and in your welcome email. If it's gone or lapsed, just reply to that email and we'll send a fresh one.
Do I need the sign-up code every time?
No - only the first time you connect Virgil, in whichever app you start with. Your other app, and any reconnect, just need your email and a fresh 6-digit code we send you then.
Can I use Virgil in both Claude and ChatGPT?
Yes. Connect each once - it's the same record across both, so what you tell one is waiting in the other.
Virgil isn't responding in ChatGPT.
Two things: pick Virgil from the "+" menu in that chat (ChatGPT drops the connector between chats), and make sure Connector Search is ON (Personalization → Custom Instructions → Advanced). Do both.
The first ChatGPT message is slow.
That's ChatGPT opening the connection (a few seconds), not Virgil. Once it's open, he's instant.
Where do the instructions go?
Claude: Settings → "Instructions for Claude". ChatGPT: Personalization → Custom Instructions. Pasting them is the single biggest thing you can do - it's how Virgil shows up ready instead of a stranger you re-introduce.
