Every time you use a new AI chat session, you start from zero. The AI does not know your name, your job, your preferences, or your time zone. So you find yourself repeating the same information over and over. "My name is Alex. I'm a software engineer at a startup in San Francisco. I prefer concise responses. I use TypeScript. I'm looking for jobs in ML engineering." This repetitive context-setting wastes time and breaks the conversational flow that makes AI assistants useful in the first place.

Tensor's Personal Context feature eliminates this problem entirely. You write your personal information once, and Tensor automatically includes it in every AI interaction. The AI always knows who you are, what you do, and how you like to communicate. And because this is Tensor, everything stays local on your machine — your personal context is never sent to our servers.

How It Works

Personal Context is a free-form text field in Tensor's settings where you describe yourself, your preferences, and any persistent context the AI should know. When you start a conversation with Tensor, the contents of your Personal Context are prepended to the system prompt sent to the AI model. This means the AI "knows" your context from the very first message, with zero effort on your part.

The Personal Context field supports plain text and basic Markdown formatting. You can organize it however you like — bullet points, sections, paragraphs, whatever structure works for you. Here is an example of what a well-structured Personal Context might look like:

# About Me

What to Include in Your Personal Context

The power of Personal Context scales with how much useful information you provide. Here are the categories that our users have found most valuable:

Basic identity. Your name, location, and time zone. This seems trivial, but it means the AI can address you by name, account for time zones when scheduling, and tailor recommendations to your geography. No more "I'm in PST" every time you ask about meeting times.

Professional context. Your role, company, tech stack, and industry. When you ask for code help, the AI already knows your preferred language and framework. When you ask for career advice, it understands your current position. When you ask for email drafts, it knows your professional context.

Communication style. Do you prefer verbose explanations or terse answers? Formal or casual tone? Code-heavy or conceptual? By specifying your preferences once, every interaction is immediately tailored. One of our beta testers wrote "I'm an expert programmer — skip basic explanations" in their Personal Context and reported saving an average of 20 seconds per interaction because the AI stopped over-explaining fundamentals.

Current goals and projects. If you are job hunting, studying for an exam, working on a specific project, or pursuing a particular goal, including it in your Personal Context means the AI can proactively offer relevant assistance. Ask "what should I work on today?" and the AI can reference your actual goals rather than giving generic productivity advice.

Recurring information. Anything you find yourself typing repeatedly belongs in Personal Context. Your shipping address for online shopping. Your dietary restrictions for restaurant recommendations. Your car model for automotive questions. Your children's ages for parenting advice. Once it is in Personal Context, you never type it again.

Personal Context in Action

Here are real examples of how Personal Context changes the AI interaction experience:

Without Personal Context:

You: "Help me draft an email to decline a meeting."
AI:  "Sure! Here's a template: Dear [Name], Thank you for
      the invitation to [meeting]. Unfortunately, I am unable
      to attend due to [reason]..."

Generic. Impersonal. Useless without heavy editing.

With Personal Context:

You: "Help me draft an email to decline a meeting."
AI:  "Here's a draft in your preferred concise style:

      Hi [Name],

      Thanks for the invite. I won't be able to make it —
      I've got a conflict with the dashboard sprint this
      week. Happy to async on anything I can help with.

      Best,
      Alex"

Tailored. Matches your tone. References your actual project.

The difference is dramatic. The AI moves from generic template generator to personalized assistant that understands your voice and context.

Privacy-First Design

Personal Context contains some of your most sensitive information — your name, location, job, salary expectations, and personal preferences. We took privacy extremely seriously in its design.

Your Personal Context is stored exclusively in your browser's local storage. It is never sent to Tensor's servers, never included in analytics, never logged, and never accessible to anyone but you. When it is sent to an AI model, it goes directly from your browser to your chosen AI provider using your own API key. Tensor is not a middleman in that transaction.

You can export your Personal Context as a file for backup, and you can delete it entirely with one click. If you clear your browser data, your Personal Context is gone — we have no copy to restore from, because we never had a copy in the first place.

For users who want granular control, Personal Context supports sections that can be toggled on and off. You might want your professional context included when using Tensor for work but excluded when browsing casually. You can create multiple context profiles and switch between them, or set up rules that automatically activate different contexts based on the domain you are visiting.

Form Filling and Automation

Personal Context does not just enhance chat conversations. It also powers Tensor's form-filling capabilities. When you ask Tensor to fill out a web form, it draws from your Personal Context to populate fields automatically. Job applications, contact forms, shipping addresses, profile setups — any form that asks for information you have already provided in your Personal Context can be filled in seconds.

This is especially powerful for job applications. If your Personal Context includes your work history, skills, education, and contact information, Tensor can fill out an entire job application form in one click. Not with random data or hallucinated information, but with your actual, verified details that you provided yourself.

Tips for Writing Great Personal Context

Based on feedback from thousands of beta users, here are our recommendations for getting the most out of Personal Context:

What Is Next for Personal Context

We are working on several enhancements. Automatic context learning will allow Tensor to suggest additions to your Personal Context based on information you frequently provide in conversations. Context sharing will let you export a sanitized version of your context to share with collaborators who want their AI tools to understand team context. And domain-specific contexts will let you maintain separate profiles for work, personal use, creative projects, and other facets of your life.

Personal Context is one of those features that seems simple on the surface but fundamentally changes how you interact with AI. Once you set it up, you cannot imagine going back to the old way of repeating yourself to a blank-slate assistant every single time.
