Breakup Calculator is a free AI-powered quiz tool that calculates your relationship’s breakup probability through 10 brutally honest questions and delivers a personalized AI-generated “roast” of your answers. The result: a probability score from 0–100% plus a crystal-ball reading that calls out your specific red flags. No sugarcoating.
The tool was built overnight as a Valentine’s Day project by a solo developer. It targets anyone who has ever had that creeping suspicion their relationship might be on borrowed time but couldn’t get a straight answer from friends, journaling, or their own denial. The AI doesn’t just spit out a number; it synthesizes your responses into a paragraph-length verdict that names the specific contradictions in your behavior.
Features
- 10-Question Diagnostic Quiz: Covers trust, communication, conflict resolution, emotional connection, and long-term outlook.
- AI-Generated Probability Score: Returns an exact breakup probability percentage based on your response pattern.
- Personalized Roast: Produces a custom paragraph that connects your specific answers into a coherent (and merciless) behavioral analysis.
- Red Flag Detection: Surfaces 2–3 specific red flags pulled directly from your responses.
- Instant Results: Delivers the full breakdown immediately after submitting the final answer.
- No Account Required: Fully accessible without signup, login, or payment.
Case Studies
I tested the Breakup Calculator to see if it could actually detect nuance or if it just gave random results. I input a scenario based on a “anxious-avoidant” dynamic: I selected options indicating I check my partner’s phone “whenever I have the opportunity” but also claimed I see a future with them “absolutely.”
The tool didn’t get confused by the contradiction. It returned a 43% Breakup Probability with a specific critique. The AI “Oracle” called me out directly, stating: “The stars see a soul who claims they are ‘absolutely’ their person, yet you’re haunting the archives like a forensic accountant.”
This was surprisingly insightful. It connected the dots between my lack of trust (phone checking) and my denial (claiming they are “my person”). The tool successfully identified that my “investigative presentation” on their ex was a major red flag, regardless of how much I claimed to love them. It felt less like a generic horoscope and more like a friend shaking me by the shoulders.
Use Cases
- Validating Red Flags: Use the tool to confirm if behaviors like “checking a partner’s phone” or “passive-aggressive Instagram stories” are serious issues.
- Social Entertainment: Friends take the quiz together to compare scores and laugh at the AI’s specific insults regarding their dating lives.
- Relationship Health Check: Couples use the specific questions about “laughing together” or “handling arguments” to open dialogues about their actual relationship status.
- Decision Support: Individuals on the fence about a relationship use the “breakup probability” score as a data point to encourage a necessary conversation.

3. After Q10, the AI returns three outputs:
- A probability percentage (e.g., 43% breakup probability).
- A status label and emoji (e.g., “Proceed With Caution ⚠️”).
- A personalized roast paragraph that references your specific answer combinations. Not a generic template.
4. Below the main roast, the tool lists 2–3 specific red flags detected from your answers. These are the behaviors the AI flagged as the most significant risk signals in your particular response set.

A: The tool operates in the browser and does not require a login. The developer has not indicated that personal answer data is stored or sold.
Q: Can I customize the questions?
A: No. The 10 questions are fixed parameters set by the developer to ensure the AI has a consistent baseline for generating the probability score.
Q: Why is the AI result so mean?
A: The creator designed the “Oracle” persona to be “brutally honest” and “savage.” It is intended to be a humorous, albeit dark, take on relationship advice.
