Why Briefed exists

Every AI has a memory system.
None of them built it for you.

Control

AI is designed to make you share. Not to protect what you share.

Every major AI is built to be a great conversationalist. The more you talk, the more it learns. Your context, your thoughts, your preferences become their data. Briefed puts you back in control. Your vault lives on your device. You decide what each AI knows, each session.

Portability

No single AI is great at everything.

ChatGPT for images. Claude for code. Gemini for research. Grok for real-time context. The best AI users don't pick one — they use each for what it does best. But every switch means starting over. Briefed travels with you.

We mapped how each one handles what you tell it

AI
What it does with your context
Memory
Training
ChatGPT
Automatically synthesizes a persistent profile from all your past conversations, updated in the background. Memory and training are separate controls — turning one off doesn't turn off the other.
MemoryPersistent
TrainingOpt out
Grok
Persistent memory on by default since April 2025. Conversations stored indefinitely, tied to your X account. If your X account is suspended or deleted, so is your data.
MemoryPersistent
TrainingUnclear
Gemini
18-month default retention connected to your Gmail, Drive, Calendar, and YouTube. Human reviewers access a subset of chats — those are kept for up to 3 years. Opting out of training means losing your chat history.
MemoryPersistent

Perplexity
Memory on by default. Subject to a 2026 lawsuit alleging hidden trackers sharing data with Meta and Google, even in incognito mode. CEO confirmed building a browser to track you outside the app.

Copilot
18 months of conversation history. Draws from your Bing, Edge, Outlook, Teams, and MSN activity for personalization. Microsoft ecosystem, all connected.

Claude
Pure context window. Nothing persists between sessions. No profile, no ecosystem. And uniquely among major AIs — training requires your explicit opt-in. You choose to share. Everyone else makes you choose to stop.

The pattern is clear. Your context is their asset.

Briefed changes the equation. Build your vault once. Share exactly what you choose, with whichever AI you need, for as long as the session lasts. It's also the perfect companion to Claude since nothing persists between sessions, Briefed fills the gap.

How it works

Three steps.
One minute.

01

Build your vault

Fill in five sections: who you are, your background, your AI instructions, what you're working on, and key people. Takes 10 minutes the first time.

02

Generate your briefing

Choose Essential (quick context), Standard (full picture), or Complete (everything). Briefed compiles your vault into a structured AI briefing.

03

Paste and go

Copy your briefing into any AI conversation. Claude, ChatGPT, Gemini, Grok. Any assistant that reads text is instantly up to speed on who you are.

The output

This is what gets pasted
into your AI.

Not a summary. Not a note. A structured briefing that tells any AI assistant exactly who they're working with. Before the first message.

Your vault. Always one click away.

Every screen, real product, straight from the sidebar.

What's inside

Everything a power user
actually needs.

AES-256-GCM encryption

Military-grade encryption. Your vault is encrypted before it touches disk. The key never leaves your device.

AI Instructions Library

15 curated operating prompts from the world's sharpest thinkers. Bezos on risk. Garry Tan on completeness. Pascal on brevity.

Bridge to another AI

Hit a context limit mid-session? Generate a structured handoff briefing and continue in Claude, ChatGPT, Gemini, or Grok without losing your thread.

People & contacts

Add key people to your vault. Colleagues, clients, partners. Their context flows into every briefing automatically.

Incognito Briefing

Generate a one-time briefing that doesn't persist. No memory. No history. For sensitive conversations that stay ephemeral.

Three briefing levels

Essential for quick context. Standard for a full picture. Complete for deep work sessions where the AI needs to know everything.

Privacy architecture

We literally cannot
read your vault.

Briefed is a Chrome extension running entirely in your browser. There are no servers. No database. No accounts. Nothing to breach.

Your vault is encrypted with AES-256-GCM before it ever touches disk. The encryption key lives only in your head. We never receive it. We never want it.

When you generate a briefing, the text is assembled locally and copied to your clipboard. It never transits a network. It never touches our infrastructure. Because we don't have any.

Briefed Never Phones Home.

FAQ

Questions.

What if I forget my password?
There is no password recovery, by design. Your vault is encrypted with AES-256-GCM and the key is derived from your password. We never receive it, store it, or have any way to recover it. Do not lose your password. Write it down somewhere safe. If you lose it, your vault contents cannot be recovered by anyone, including us.
Is my data really private?
Yes, completely. Your vault is encrypted on your device and never leaves it. Briefed has no servers, no database, no accounts. If Briefed disappeared tomorrow, your .briefed file would still decrypt and work. We have no way to access your data because we never receive it.
What browsers does Briefed work with?
Briefed is currently available as a Chrome extension that works in Chrome, Edge, and Brave. A desktop app for Safari and Firefox users is in development. If you're on Safari, you can install Chrome just for Briefed. It takes two minutes and your vault stays fully encrypted and local either way.
What happens after the 7-day trial ends?
The extension drops to Essential briefings only (still useful). Upgrade with a $49/year license key from Gumroad to unlock Standard, Complete, the full AI Instructions library, and Incognito Briefing. Your vault and all your data are always yours regardless.
Which briefing depth should I actually use?
Standard covers most sessions — your identity, background, current work, and AI instructions. That's the right depth for drafting, thinking through a problem, or any normal work session. Drop to Essential for genuinely trivial asks, where full context would just be noise. Go Complete only when the specific people in your vault or your communication style actually matter to that conversation. More context isn't always better — pasting a full briefing into a simple question dilutes what the AI is actually paying attention to, the same way over-explaining a request to a person can bury the point.
Does Briefed work with memory turned off?
That's actually the point. Briefed works regardless of whether AI memory is on or off. It gives the AI everything it needs at the start of each conversation. For sensitive work where you want memory off, use Incognito Briefing: full context in. Nothing remembered.

Stop explaining yourself.

Your vault is waiting. Takes 10 minutes to build. Saves hours every week.
