Building Your Own AI Interpreter with Flitto Chat Translation’s Custom Assistant

Custom Assistant is a core feature of Flitto Chat Translation that enables personalized translation by learning from the user’s own dataset.

What Is Hyper-Personalization in Translation?

Hyper-personalization enables AI to:

  • Understand a user’s identity, background, and preferences
  • Reflect domain knowledge, personal vocabulary, and naming conventions
  • Interpret meaning based on context that is not explicitly stated

By using Custom Assistant, Users can train the AI with:

  • Preferred name spellings and aliases
  • Job titles, company names, and internal terminology
  • Domain-specific documents (manuals, presentations, reports)
  • Frequently used expressions, links, and files
  • Style preferences and recurring vocabulary

This information forms a personal translation dataset, which the AI references in real time during conversations.

The result is translation that is more consistent, accurate within context, and faithful to the user’s identity.

A Simple Sentence, Two Very Different Meanings

Consider the sentence:

“Did you see Boston yesterday?”

In a generic translation system, this would be translated literally often interpreted as referring to the city.

But now imagine the following context:

  • The user’s profile data indicates they are a Boston Red Sox fan
  • Their personal dataset includes sports-related vocabulary and preferences
  • Prior conversations suggest frequent references to baseball

With Custom Assistant, the AI understands that “Boston” is more likely shorthand for a baseball game, not a location.

The translation naturally becomes:

“Did you watch the Boston game yesterday?”

This is hyper-personalization in action, contextual inference based on user identity.

Why Personal Datasets Matter

When users upload their own datasets, Custom Assistant delivers tangible advantages:

1. Identity-Preserving Translation

Names, titles, and brands are translated exactly as the user intends.

For example:

  • “이정수입니다”
    → “This is Simon Lee.”
    (instead of a literal romanization)

This is critical in professional settings, meetings, presentations, and first introductions, where identity accuracy matters.

2. Domain-Aware Interpretation

Words change meaning across industries.

Take the term “reconstruction”:

  • Medical context → surgical reconstruction
  • Aesthetic context → cosmetic reshaping
  • Technical context → system or data restoration

Custom Assistant prioritizes meaning based on uploaded documents and domain materials, ensuring expert-level contextual accuracy.

3. Consistency Across Conversations

Once preferences are learned, they are applied automatically—every time.

This eliminates:

  • Repeated corrections
  • Terminology inconsistency
  • Style drift across languages

The AI becomes more aligned with the user the more it is used.

Toward a World of Personal AI Interpreters

Flitto’s vision is clear:

An AI interpreter should understand the person speaking.

Custom Assistant is the foundation of that vision.

By allowing users to define their own linguistic identity terms, preferences, context, and intent, Flitto Chat Translation moves beyond translation as a utility and toward translation as understanding.

As global communication grows more complex, the future belongs to AI that adapts not just to languages, but to people.

Flitto will continue to build that future, through data, personalization, and AI designed to truly understand you.
