Story types

The voices your product can hide inside.

Eight types, each tuned to how that community actually writes — so your product lands as a passing detail, never an ad.

⚖️
AITA
Moral-courtroom posts. Your product is just the tool the narrator happened to be using when it all kicked off.
01 ⁄ 06
🍿
Family
In-law standoffs, sibling fallout, the secret that finally came out at dinner.
02 ⁄ 06
💔
Couples
Texts, exes, the fight that was never really about the dishes.
03 ⁄ 06
🧷
Workplace
Bad bosses, malicious compliance, the quit story the whole thread roots for.
04 ⁄ 06
😈
Revenge
The neighbor, the HOA, the lunch thief. Slow, deserved, satisfying.
05 ⁄ 06
🤫
Confession
2am admissions strangers can't stop replying to. Plus Wholesome and a random mix.
06 ⁄ 06
Real output

This is what comes out.

Not “in today's fast-paced world.” Real specifics. Real mess. Real comment-section gasoline.

A Heartwarming Family Story About Misunderstanding

In life, communication is essential. Last week, an interesting situation arose with my family member that taught me valuable lessons about empathy and patience. I want to share this experience to help others navigate similar circumstances...

AITA for telling my sister (28F) her all-black wedding looks like a funeral?

Throwaway because she follows my main. My sister Megan is getting married in June and she's been planning this thing for two years. Cool. The problem is she announced last month that the theme is “midnight elegance” which apparently means everything — bridesmaid dresses, flowers, table cloths, the cake — is matte black.

So today at brunch she's showing me the centerpieces. Black roses. Black candles. Black napkins. And I, exhausted from 4 hours of sleep with a teething baby, said, very quietly, “Meg this looks like we're burying someone.”

She put down her mimosa. She did not pick it back up. Mom kicked me under the table so hard I think I have a bruise. My sister hasn't texted me since 11am.

My husband says I was right but I should've said it nicer. My mom is now calling me hourly. AITA?

EDIT: No I will not be matron of honor anymore apparently. EDIT 2: She just texted me a screenshot of this post. Hi Megan.
