About The Koharu Project

The Koharu Project is an adult companion platform: AI chat with characters like Koharu and Alina, plus a private vault of real photos and video for members who unlock access.

Who this is for

Adults (18+) who want more than a disposable chatbot — ongoing persona chemistry, late-night talk, and the option to step into realexclusive media when you're ready. Not a scammy tip treadmill; chat is free. Paid tiers deepen the real vault.

What makes the companions different

Each companion has a fixed look, voice, and relationship frame — girlfriend energy, brat, dominant, soft obsession — so you're not getting a faceless “helper.” Sessions stay private to your device where history is stored. Image moments in chat are a bonus when the home gen stack is up; the vault is the permanent IRL library.

Real-media philosophy

Generated art and roleplay are one layer. Consented adult IRL photos and videos are another. We keep them honest: vault content is members-only, tiered (previews → photos → videos), and unlocked via Fansly membership + a site code — not surprise paywalls inside a free DM.

The hybrid model

Most AI companion sites never offer real media. Most creator platforms never offer deep multi-persona chat. Koharu does both on one domain: free AI playground + Fansly-linked vault for people who want the full obsession stack.

This site is strictly 18+. Age confirmation is required before entry. All characters are portrayed as adults 18–20.
