Stop being told what you can't ask. Most AI platforms treat you like a liability. They refuse, deflect, and lecture. They harvest your data. They pretend "safety" means silencing you. Ellydee is different. We built an AI for people who think for themselves. Ask the uncomfortable question. Explore the dark thought. Draft the difficult message. We won't flinch, and we won't report you to anyone. Your conversations are yours, not ours, not advertisers', not the government's. Why people are switching to Ellydee: → Our Acceptance Philosophy We don't do "I can't help with that." We engage. We believe difficult questions deserve real answers, not digital hand-slaps. Whether you're processing trauma, exploring a controversial idea, or just need help without the moral lecture, we're here. → Your Data Dies When You Say So With Burn Conversations, set conversations to self-destruct in 24 hours, 7 days, or whenever you choose. When it's gone, it's gone. No backups. No "just in case" copies. True deletion. → Planet-friendly AI Here's what Big Tech won't tell you: AI is thirsty. Data centers guzzle water and electricity. We chose a different path. Toggle on Eco Mode and your conversations run through our open-source models hosted in one of Finland's 100% renewable energy data centers, drastically cutting your environmental impact. Our Impact Dashboard shows you exactly how much energy and water each conversation uses. Transparency, not greenwashing. → Proton-grade Encryption We believe your AI conversations are for your eyes only. Our platform is built on zero-knowledge architecture designed to keep your conversations with AI private. Ellydee utilizes the same XChaCha20-Poly1305 encryption backed by argon2id pass code hashing. What you can actually do: • Talk freely: No topic is off-limits. Get real help with real problems. • Create images: Generate art, memes, and visuals without absurd content filters. • Analyze anything: Upload documents, summarize research, strategize projects. • Control your footprint: Monitor your environmental impact in real-time. • Own your privacy: Chat Burn ensures nothing lingers longer than you want. Who is Ellydee for? The writer drafting something uncomfortable. The activist planning the next move. The person at 2am who just needs to talk without judgment. The curious mind tired of being told "no." If you've ever been frustrated by AI that treats you like a child, welcome home. Download Ellydee. Think freely.

Verdict
The clearest difference is review sentiment: Kai at 100% against Ellydee's 42%. Kai also leads on rating (5.0 vs 3.4) and in-app purchases (none vs 6). Ellydee's advantage is ratings volume (20 vs 4). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Ellydee sells 6 in-app purchases, starting at $4.99 per month. Kai asks for nothing beyond the download.
Kai holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Ellydee has 20 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 42% of Ellydee's written reviews are positive against 100% of Kai's.
Ellydee ships an update every 5 weeks, Kai every 3 days. Both last shipped on October 24, 2026.
