"C.ai Replacement" Idea: A Trope-first story engine for the booktok/fanfic community (Free to take, I just want it to exist and ik some people here have the skills to possibly make this!)
The Summary:
Character.ai is great, but it’s built like a chatbot. It’s too "agreeable" for slowburns, it gets "Dory Syndrome" (memory loss), and it’s getting bloated with features writers don't want. My idea is TropeVerse (or something similar): An interactive storytelling app that blends the Pinterest aesthetic with AO3’s community credit and a trope-driven AI engine.
The Full Idea:
- The "Trope-First" Logic: On this app, you don't just "chat with a bot." Creators build "Worlds" based on tropes (e.g., Grumpy x Sunshine, Enemies to Lovers, Dark Academia). The creator writes the intro, the setting, and the "rules" of the world/trope. They can add tags and moodboards to help users understand and find the world.
- Discovery Hubs: The app is organized into Hubs based on aesthetics and vibes (e.g., "Coastal Island", "Small Town Mystery", "1800s Regency"). Users follow these Hubs to find new stories and intros. It’s a "secret handshake" for fans—everyone knows the Coastal Island hub is for those OBX-style vibes.
- The Sub-In & Edit System: Users pick a Story Starter they love and "Sub-In" their own characters/personas with their own set traits into slots like [MMC] or [FMC].
- Full Control: Even if a creator wrote the intro, the user can edit the intro, lore, and rules before they start. You can take a creator’s framework and tweak it to fit your specific vision perfectly.
- The AO3/Wattpad Model: It’s a creative hub. You can "Remix" a story, follow creators for their writing style, and—most importantly—"Merge to Chapter." You select your favorite chat messages, and the AI turns them into a polished chapter you can publish to your profile.
- Solving the Memory/Filter Issue:
- Auto-Summary: When memory gets full, the AI generates a summary for the user to edit/confirm, ensuring the "Lore" never dies.
- Trope Pacing: Because the AI follows a trope (like "Slowburn"), it’s programmed not to be agreeable or fall in love in the first 5 minutes. It stays mean/grumpy as long as the plot requires.
- The Aesthetic: The app shouldn't look like an illegal website. Instead it would be dark and sleek. Integration with Spotify for playlists and Pinterest for visual inspiration.
- The Business Model: No intrusive "mid-chat" ads. Use an "Energy" system where users choose to watch an ad for more messages, or can get a subscription for no limits.
- Free vs. Paid Tiers: Free users get 4 character slots per story; Paid users get 8 slots. Monetisation follows a "Wattpad-style" energy system: free users get a "Refuel" pop-up every 30 minutes to watch an ad, or they can "stack" ads (watch 5 ads for 4 ad-skips) to keep their flow uninterrupted. Paid users have no ads and no limits, with a short "cool down" mode if servers are being hammered.
- Community & Creator Rewards: To encourage high-quality writing, the Top 10 Creators with the highest engagement each month receive 1 week of free Premium. If they are already subscribers, they get a 10% discount on their renewal. This keeps the best world-builders active and rewarded.
- A "User Responsibility Waiver" at the start: Since it's a creative writing tool, the user acknowledges that they are the "Director" and the AI is just a "Scriptwriter." This helps protect the app from being blamed for what the AI says in a private chat.
Why this works: It moves away from the "AI Bot" legal trap (DMCAs) because you aren't hosting copyrighted characters—you’re hosting user-generated tropes. It’s a tool for writers and roleplayers who want a real narrative engine that understands "vibes."
I don’t want to build this or make money from it—I just want to use it. If you're a dev looking for a project with a built-in audience, please take this and run with it! Suggestions & comments?
