MNAI beats the published state of the art at predicting real people.

It measurably outperforms them at the thing that matters: predicting real people. In a published benchmark on 2,058 real people (Twin-2K-500), the Mnemonic Digital Twin scored 89% of the maximum accuracy any predictor can achieve — above the ~85% state of the art reported in the academic literature (Park et al., 2024). You can read the full methodology in our fidelity report. Beyond accuracy, public AI tools have no knowledge of your brand. They cannot access your internal documents, your customer personas, your campaign history, or your analytics data. They may also produce confident-sounding answers that are completely fabricated. The Digital Twin is fundamentally different: it is trained exclusively on your private information and connected directly to your analytics platforms. It indicates where its answers come from, whether from your knowledge base or general industry knowledge, so you can always evaluate the source. Your data never leaves your secure environment, is never used to train external models, and every answer is grounded in your actual business data rather than generic internet knowledge.

The Digital Twin is a custom AI built specifically for your brand. It lives in a secure web application where your team can ask questions in plain English and get instant, informed answers drawn from extensive world data analyzes, your own company knowledge and third party data. Think of it as a team member who has read every document your brand has ever produced, every campaign deck, every persona profile, every product brief, every policy document, every customer complaint, every web analytics report, every sales table, and can recall any detail on demand. It also connects to your live data, so you can ask about real performance metrics alongside strategic and product questions, all in one place.

The Digital Twin can answer questions across your entire knowledge base. This includes product details (ingredients, benefits, usage instructions, suitability for different skin types), customer personas and their OCEAN personality profiles, brand identity and messaging guidelines, campaign strategies and marketing calendars, company policies (shipping, returns, exchanges, support procedures), and any other documents you provide. You can ask broad questions like "List all our customer personas" or drill into specifics like "What are [Persona Name]'s emotional drivers and preferred channels?" If the information exists in your files, the Digital Twin can find it, explain it, and connect it to related topics.

Yes. The Digital Twin connects directly to your email, marketing platform, web analytics or any other connected data source. You can ask questions like "What was our email open rate last month?", "Which products had the highest revenue this quarter?", "How is our organic traffic trending compared to last year?", or "What were our top-performing campaigns?" It will query your actual data and return clear, formatted answers with real numbers.

OCEAN is a well-established personality framework that measures five traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. Mnemonic uses this framework to build rich customer persona profiles for your brand. The Digital Twin is an expert in OCEAN profiles and can explain any persona's personality traits, motivations, needs, preferred channels, emotional drivers, and purchasing behaviors. You can ask it to compare personas, suggest messaging strategies for a specific personality type, or explain how a persona's traits influence their buying decisions.

Yes. The Digital Twin maintains full conversational memory within each session. If you ask about [Persona Name] and then follow up with "What are her needs?" or "How should we target her?", it understands you are still talking about the same persona. It correctly resolves pronouns like "her," "it," and "that campaign" by referring back to the conversation context. This makes it easy to have natural, multi-turn conversations where you dig deeper into a topic without repeating yourself. A typical workflow might be: ask about a persona, then ask about their preferred channels, then ask for messaging recommendations, and finally ask about analytics for campaigns that targeted that persona. All in one continuous conversation.

The Digital Twin accepts a wide range of document types including PDFs, PowerPoint decks, text files, spreadsheets, and other common business formats. Documents are automatically processed, cleaned of conversion artifacts, and organized into a searchable knowledge base. The system intelligently splits large documents into sections while preserving context, so information from a 50-slide campaign deck is just as retrievable as a one-page product brief. Campaign decks, brand guidelines, product specs, policy documents, marketing calendars, research reports, and persona profiles are all excellent candidates. Besides business formats, the Digital Twin can ingest JSON, SQL, PGV, BigQuery, and other file formats that are used for programmatically exchange information. Third party systems like HubSpot, Google Analytics, Ad Accounts, etc., can be connected directly vie oAuth2.0 APIs.

You can add new documents at any time. The ingestion process is incremental, meaning new documents are merged into the existing knowledge base without disrupting or overwriting anything already there. If you launch a new campaign, create a new product line, or update a policy, the new information can be added and made available to the Digital Twin quickly.

The knowledge base is designed to scale. We currently have production deployments with over 360,000 documents covering years of campaign history, dozens of personas, full product catalogs, and comprehensive brand guidelines. There is no practical limit that would affect a typical brand deployment.

We connect your email marketing platform data and web analytics data into the Digital Twin during onboarding. Once connected, the system automatically understands your campaign names, product names, traffic channels, and date ranges. Your team can then ask natural-language questions about any of this data without needing to open a dashboard, build a report, or know how to write queries. Just ask a question in plain English, "Compare our email conversion rates from Q1 versus Q2" or "Which traffic channel drove the most new users last month?", and the Digital Twin translates that into a precise data query behind the scenes and returns a formatted answer.

The Digital Twin uses oAuth2.0 which is the industry standard for connecting systems. If you ever logged into a service with your Google or Apple account, you already used Oauth2.0. The process is the same: Our system guides you to the Google LogIn, i.e., for Google Ads, and you can decide with data you want to include in the Digital Twin. Once connected, everything runs on auto pilot and the Digital Twin updates the data automatically in the background.

Access is controlled through individual user accounts. Each team member gets their own login credentials with a unique username and password. There is no shared access or anonymous usage. You control exactly who on your team can use the system, and accounts can be added or removed at any time.

Your data is protected through multiple layers of security. All communications are encrypted in transit. User passwords are securely hashed and salted using industry-standard methods. The system enforces rate limiting to prevent abuse (for example, login attempts are capped to prevent brute-force attacks). All user inputs are sanitized to prevent injection attacks, and all outputs are sanitized before display. The application runs on secure cloud infrastructure with strict access controls, security headers, and content security policies.

Onboarding follows a straightforward process: 1. Gather documents: You provide your brand documents (decks, PDFs, guidelines, product info, persona profiles, policies). 2. Ingest and index: We process your documents into the knowledge base, cleaning and organizing them for optimal retrieval. 3. Connect Third Parties: We connect your email marketing and web analytics data so the Digital Twin can answer performance questions. 4. Deploy: We set up your branded Digital Twin on secure cloud infrastructure with your logo and custom domain.

A standard deployment typically takes one to two weeks, depending on the volume of documents and the complexity of analytics connections. The biggest variable is document preparation: If you have your brand documents organized and analytics access ready to share, the technical setup moves quickly. Mnemonic handles all of the processing, indexing, and deployment work on our end. Your team's involvement is primarily limited to providing the source materials and reviewing the finished product before it goes live.

You will need to provide your brand documents (any format is fine, we handle the conversion and cleanup), access or exports from your Third Party Tools (email, marketing platform or web analytics), your brand logo and any color or styling preferences for the interface, and a list of team members who need user accounts along with their email addresses. That is it. There is no software to install on your end, no IT integration required, and no ongoing technical maintenance for your team to manage.

The Digital Twin is a web application accessible from any modern browser, Chrome, Safari, Firefox, or Edge. There is nothing to download or install. You simply navigate to your custom URL, log in with your credentials, and start asking questions. The interface has a main chat area for your conversation, a sidebar with your temperature control and conversation history, and a link to the Prompt Library for inspiration. It works on desktop, laptop, and tablet browsers.

Example 1 - Persona Research: You: "Tell me about [Persona Name]." Digital Twin: [Returns a detailed profile including bio, personality traits, needs, preferred channels, emotional drivers, and shopping behaviors] You: "What messaging would resonate with her?" Digital Twin: [Provides tailored messaging recommendations based on the persona's OCEAN profile and motivations] Example 2 - Analytics: You: "What were our top 5 products by revenue last quarter?" Digital Twin: [Returns a formatted table with product names, revenue figures, and purchase volumes] You: "How did [Product Name] perform compared to the previous quarter?" Digital Twin: [Returns a comparison with percentage changes] Example 3 - Campaign Planning: You: "What did we do for [Holiday Campaign] last year?" Digital Twin: [Returns campaign details, messaging themes, and timeline from your campaign documents] You: "What were the email open rates for that campaign?" Digital Twin: [Queries your analytics data and returns the actual performance metrics] Example 4 - Brand and Policy: You: "What is our return policy?" Digital Twin: [Returns the complete return and exchange policy from your brand documents] You: "What channels should we use to reach [Persona Name]?" Digital Twin: [Recommends channels based on the persona's profile, engagement preferences, and OCEAN personality traits]

The temperature slider (from 0 to 1) controls how creative or precise the Digital Twin's responses are. A low temperature (close to 0) produces more focused, factual, and consistent answers, ideal for pulling exact data or specific document details. A higher temperature produces more creative and varied responses, useful for brainstorming messaging ideas or exploring new angles. Most users keep it low for day-to-day research and turn it up when they want creative input.

The Prompt Library is a curated collection of ready-to-use questions and conversation starters published by Mnemonic. It is accessible directly from the Digital Twin sidebar and opens in a new tab for easy reference. It helps your team get the most out of the Digital Twin by providing proven prompts for common use cases like persona deep-dives, competitive analysis, campaign planning, product research, and analytics exploration. Think of it as a quick-start guide. Your team can copy a prompt, paste it into the chat, and immediately get a useful answer. Over time, most users develop their own go-to questions, but the library is a great way to onboard new team members.

Yes. The Digital Twin displays your complete chat history in a sidebar panel. Each past conversation is listed with a timestamp and can be expanded to review both what you asked and what the Digital Twin answered. This makes it easy to revisit previous research, reference a data point from an earlier session, share findings with colleagues, or pick up where you left off. Your history is private to your own account, other users cannot see your conversations.

Absolutely. The knowledge base is designed for continuous growth. As you create new campaigns, launch new products, update personas, or generate new research, those documents can be added incrementally at any time without disrupting the existing knowledge base. New documents are merged in alongside everything already there. The same applies to analytics data. As new months of performance data flow in, they become available for querying automatically. Many clients treat the Digital Twin as a living resource that grows smarter as their brand evolves.

The Digital Twin grounds its answers in your actual documents and data, and clearly indicates when an answer comes from your knowledge base versus general industry knowledge. This source attribution makes it easy to evaluate any response. If an answer seems off, it is usually because the underlying document needs updating or the question could be phrased more specifically. Because you control the knowledge base, you can correct information by uploading revised documents at any time. For analytics queries, the system pulls directly from your data, so the numbers always reflect what is actually in your platforms. If the Digital Twin genuinely does not know something, it will say so honestly rather than guessing.

The Digital Twin is hosted on scalable cloud infrastructure that supports multiple concurrent users. Your entire marketing team can be logged in and asking questions simultaneously without performance degradation. Each user's conversations are private to their own account.

The Digital Twin is a responsive web application that works in any modern browser, including mobile browsers on phones and tablets. While it is optimized for desktop and laptop use where the sidebar and full chat interface are most comfortable, it is fully functional on mobile devices as well.

Start with the measured difference: on the Twin-2K-500 benchmark (2,058 real people), the Mnemonic Digital Twin reaches 89% of the human accuracy ceiling — above the ~85% published state of the art. Free AI tools have never been measured against your customers at all. Beyond that, public AI tools do not know your brand. They cannot access your private documents, your customer personas, your campaign history, or your real analytics data. They frequently hallucinate information that sounds plausible but is entirely made up. You also cannot control who sees the data you paste into a public tool, and that data may be used to train models that serve other companies. Including your competitors. The Digital Twin, by contrast, is grounded in your actual data and documents, provides source attribution so you know where answers come from, keeps your information completely private, and gives answers specific to your brand rather than generic advice. It is the difference between asking a stranger on the street and asking the most well-informed member of your team.
