Why Features Get Sparklo About FAQ
01

Built to solve real problems

Every feature exists because a creator needed it.

I

Creators Protected

You spent weeks crafting a character — the personality, the backstory, the subtle details that bring them to life. Then someone copies it in five seconds. Sparklo uses end-to-end AES-256-GCM encryption across the entire chain: server storage, transport, and local vault. Your work stays yours.

II

Creators Heard

You publish a character, then... silence. Did anyone use it? Did they enjoy it? Sparklo's Repo system lets users send favorite chat moments and reactions to your space — anonymously if they prefer. No awkward DMs. Just genuine appreciation, delivered respectfully.

III

Human Spark Valued

In an era of mass-generated content, handcrafted characters deserve recognition. Creators who draw their own art and write original stories earn certification badges and discovery priority. AI is our tool, not our brain.

IV

Characters Remember

Long conversations inevitably dissolve into forgetting — entropy erodes every shared moment. Sparklo's MMPEA memory architecture gives characters persistent, coherent memory. It understands stories, not just text. Your journey together doesn't fade.

If nobody makes the tool I need, I'll make it myself. Alc.Erumra, creator of Sparklo

One person, one vision

Alc.Erumra

Independent developer and AI narrative architect. Since 2023, I've designed memory systems for persistent AI characters, built content protection frameworks for digital creators, and developed prompt engineering tools used across multiple platforms.

When existing tools hit their limits, I stopped patching and started building. Sparklo is the result — a ground-up reimagining of what AI character interaction can be.

Solo-built. Full stack. 50,000+ lines of original code — from memory engine to encryption layer, from Android app to cloud infrastructure.

Sparklo — Spark (a flash of inspiration) + lo (small, gentle, intimate).

Questions

Yes. Sparklo doesn't bundle AI model credits — you bring your own Claude, GPT, Gemini, OpenRouter, or compatible provider. Android/local mode connects from your device; Hosted Web connects through Sparklo's hosted engine using your configured provider profile.

No. Invite codes only allow beta registration. App access and APK downloads require a Sparklo membership or an existing access grant. Existing Angel users keep lifetime access, and existing paid users keep transition access. See Pricing for details.

Android/local mode stores private app data on your device. Hosted Web stores private app data in a per-user server database so the browser version can work. Creator-protected content uses Sparklo's protection and masking flow. We don't sell user data. Read our Privacy Policy for full details.

None. Sparklo is an independent project built from zero. Different architecture, different philosophy, different codebase.

Not from external formats. Sparklo uses its own character system designed around the worldbook engine and content protection. This is intentional.


Every character deserves to be remembered.
Every creator deserves to be seen.
