INTA
: How to use it, features, and the business problems it solves

What is INTA?

INTA is a fortune-telling app where you talk with "トンジャ" (Tongja), an AI fortune teller that remembers your previous consultations, provided by FLOAT Co., Ltd. (FLOAT株式会社) in South Korea. Its store name is "INTA 続きが話せるAI占い｜四柱推命・占星術," and it is available on iPhone and iPad (App Store) and Android (Google Play).

Based on a Four Pillars of Destiny (四柱推命) chart calculated from your date and time of birth, you can ask Tongja about love, work, money, relationships, and more. Its distinguishing feature is that you can pick up where your last consultation left off without explaining your situation from scratch each time. Western astrology, tarot, face reading, dream interpretation, compatibility, and name analysis are also bundled into the one app. It is free to start, with in-app purchases (subscriptions and crystals) (as of November 2026).

Besides fortune-telling, INTA also suggests to-dos and schedules based on the day's fortune and energy flow. The official site explains that the name stands for "life is timing," and it introduces many execution-support features, such as assigning to-dos to the best time slots and re-suggesting to-dos you postponed. The operator, FLOAT, is the same company behind the English-correction keyboard "Eng-Helper," which is also listed on this site.

Basic information

How to use INTA

1. Install the app and sign in Install it from the App Store or Google Play and create an account with Apple, Google, or email.
2. Enter your date and time of birth These form the basis of your Four Pillars chart. If you don't know your birth time, you can leave it blank and fix it later. The official guide says entering gender, birth region, and lifestyle pattern improves the accuracy of suggestions.
3. Talk to Tongja Open the chat from "対話する" (Talk) on the home screen and ask about worries such as love or work. Because it answers based on previous conversations, you can continue where you left off, for example, "Should I contact the person I told you about last time?"
4. Try other readings Open the perpetual calendar (your chart), tarot, compatibility, dream interpretation, face reading, and more from the home screen or menu. You can also ask Tongja directly about the results.

Main features

• AI Tongja (chat with an AI fortune teller) An AI fortune teller trained on traditional Korean interpretations of the Four Pillars. It answers questions about today's fortune, love, and work in conversation, taking into account the five elements, ten gods, and major luck cycles. It has four tones: warm, calm, coach-like, and playful. According to the official site, it can also run real-time web searches and help find restaurants.
• Perpetual calendar and Four Pillars chart Explains the four pillars of year, month, day, and hour across four layers: heavenly stems and earthly branches, ten gods, twelve life stages, and special stars. It also shows major luck cycles, yearly flows, and the "three calamities" (三災) period. The October 2026 versions added luck-flow graphs (5 years, 10 years, entire life) and monthly fortune cards (other months, 10-year and lifetime flows, etc. are premium).
• Western astrology Reads your personality from three viewpoints—sun, moon, and rising signs—using a natal chart calculated from your birthplace and birth time. Added in the September 2026 version (2.6.6).
• Tarot, face reading, dream interpretation, name analysis Tarot offers one-, three-, and five-card spreads interpreted by AI. Face reading measures the mouth, chin, and eyes from a single photo and produces a report; dream interpretation reads your dream and generates an image. Name analysis suggests ten names that complement the useful element (用神) in your Four Pillars chart.
• Compatibility Register partners, friends, family, or colleagues to get scores and keywords for love, business, and friendship based on both people's Four Pillars.
• AI Solomon Trial Enter both sides of an argument or a choice you can't decide on, and it sorts out the issues in a first-, second-, and third-instance format and gives a verdict and its reasons.
• Playground Content that creates illustrations and reports from your Four Pillars, such as "Who was I in a past life?" or "What if I became an ad model?" You can also chat with the characters that appear in the results.
• To-do and schedule suggestions Calculates the day's energy from the Four Pillars, MBTI, biorhythms, weather, and more, and assigns to-dos to suitable time slots. It also re-suggests postponed to-dos, breaks down large tasks, and has a focus mode plus trophies and points.

Pricing

INTA is free to start with in-app purchases. The differences between the free version and premium listed on the official site are as follows (as of November 2026).

The in-app purchase list on the Japanese App Store shows the following items (as of November 5, 2026; only some of the items displayed).

According to the App Store version history, subscriptions became three plans—Basic, Pro, and Ultra—in the September 2026 version (2.6.6). The price of Basic and the billing period of each plan are not stated in the App Store list or on the official site. The terms of service state that prices and billing periods (monthly, yearly, etc.) are shown on the in-app payment screen and that subscriptions renew automatically unless canceled.

In-app activities (completing to-dos early, focus mode, check-ins, daily quests, trophies) earn points, which can be used for things like drawing one extra tarot card (5 points). Once the free conversations are used up, each conversation with Tongja deducts points, or crystals if you don't have enough points.

The technology behind INTA

The official site says INTA is different from "just combining a general-purpose AI with a perpetual calendar" and lists the following points. All of these are statements on the official site.

• It trains and refines its own AI on specialized Four Pillars data
• It uses "RIDM," a character-based AI platform built on emotion and memory that FLOAT developed in 2025 (registered Korean patent No. 10-3009272)
• It was selected as one of 50 tester companies in the "Advanced GPU Utilization Support Program" of Korea's Ministry of Science and ICT and NIPA, and trained an auto-tagging model in-house
• It has published two Korean-language models it fine-tuned itself on Hugging Face under the Apache 2.0 license

The official site explains that Tongja's responses combine more than 80 template messages with an LLM and use caching to respond quickly.

Pros and cons

Pros

• Remembers your previous consultations so you can continue where you left off
• Four Pillars, Western astrology, tarot, face reading, dream interpretation, compatibility, and name analysis in one app
• Chat with AI Tongja is available three times a day even on the free version, and compatibility analysis is free

Cons

• The billing period of each subscription plan and the price of Basic are not stated on the official site or in the App Store list
• It has many features, including to-dos, energy, and focus mode besides fortune-telling, so the screens carry a lot of information for people who only want readings
• On the Japanese App Store there are still too few ratings for a summary to be shown (as of November 2026)
• The operator is a Korean company, and support is by email or a Korean-language KakaoTalk open chat

Reviews and reputation

As of November 5, 2026, the Japanese App Store has too few ratings and reviews to show a summary. Google Play shows 5,000+ downloads. The app is updated frequently, with more than 20 App Store versions released between July and November 2026, and improvements to the Four Pillars readings and Tongja's responses continue.

The official site says Tongja picks up the emotional flow of a conversation and learns the user's tendencies, so conversations deepen over time. Regarding results, it states that the Four Pillars, MBTI, and biorhythm information is not a medical diagnosis or scientific prediction, and the September 2026 update notes also advise not to take health content based on the Four Pillars at face value and to consult a specialist.

How it differs from other AI fortune-telling apps

If chart calculation accuracy matters most, OpenFate is a candidate; if you just want quick tarot, AIのタロット占い; and if you want to keep consulting on various readings in one conversation centered on the Four Pillars, INTA.
