My Info Vault: Personalize Your AI in Arc

Unlock the full potential of your AI writing assistant by personalizing its understanding of you. Arc’s ‘My Info Vault’ offers a secure, private space to store your essential personal and professional details, ensuring your AI always writes with your unique context in mind. I built Info Vault because I was tired of re-typing the same details every time I used an AI assistant — and with over 28,000 Arc users across 50+ countries now relying on it, I’m clearly not the only one. Every month, users create around 30 personal info entries that feed directly into AI-generated responses, making every output feel like it actually knows them.

Getting Started with My Info Vault

Accessing your My Info Vault is straightforward. It’s designed as a dedicated hub within the Arc application to keep your important information organized and readily available.

This is your starting point. If you’re new, it will appear empty, ready for you to populate. The interface is clean and focused, ensuring you can start building your personal AI context without any distractions.

Adding and Managing Your Information

Populating your vault is simple and intuitive. You can create as many entries as you need, each with a clear title and descriptive content.

Adding a New Item

To add your first piece of information, tap the ‘Add New Item’ button or the floating action button.

You’ll see fields for a ‘Title’ and ‘Content’. Be specific! For example, a title like “My Professional Role” with content such as “Senior Software Engineer specializing in backend development with Python and AWS” provides rich context for the AI.

Once you have filled in your details, simply save your entry. You can see how a completed entry looks below, providing a clear reference for the AI to pull from during your writing sessions.

Pro-tip: Break down your information into smaller, logical chunks (e.g., “Contact Info”, “Current Projects”, “Writing Tone”) rather than one giant block. This allows for much more granular control when selecting context in the AI Writer.

Managing Your Vault

Your vault can grow to include job titles, personal interests, project details, or any information that helps the AI understand your needs better.

Your entries are listed clearly in your vault. To manage them effectively:

Edit: Simply tap on an existing entry to modify its title or content at any time.
Delete: Remove entries you no longer need by accessing the edit options for that item.
Reorder: Grab and drag entries into your preferred order. This helps you prioritize the most frequently used information.

Using Your Vault with the AI Writer

The real power comes when you integrate your My Info Vault with the AI Writer. When you’re using the AI writer tool, you can selectively choose which vault items to include in your prompt or context.

With 2,737 AI Writer sessions per month pulling from Info Vault entries, this is not a feature that collects dust — it is an active part of thousands of users’ daily workflow. That’s 2,737 times every month someone’s writing was made more personal and accurate because their Info Vault did the heavy lifting. This allows the AI to draw upon your stored information to generate responses that are specifically tailored to your background, preferences, and current needs. Whether you’re drafting an email, writing a report, or brainstorming ideas, your personalized AI context ensures maximum accuracy and relevance.
