Comparison
Selvia AI vs LemonSlice
Both offer real-time AI avatars. The biggest differences are what's included, price, per-user memory and kiosk mode — here's an honest, side-by-side comparison.
Selvia AI is an all-inclusive, turnkey real-time AI avatar starting at $1/hour — the avatar, speech, language brain and per-user memory are all included. LemonSlice (from about $0.14/min) is best known for turning a single image into a talking avatar, with body gestures. Choose Selvia AI for an affordable, all-in-one live avatar with memory and always-on kiosk mode; choose LemonSlice if your priority is image-to-avatar or creative gestures.
Price: Selvia AI vs LemonSlice
Selvia AI starts at $1 per hour (about $0.03 per minute), and that price is all-inclusive. LemonSlice runs roughly $0.14–0.19 per minute, billed as credit subscriptions ($8–240/month) with no free tier. The per-minute gap is several times over, and Selvia AI also includes per-user memory and 60 free minutes a month — neither of which LemonSlice offers.

Where Selvia AI comes out ahead
All-inclusive & affordable
One flat price covers the avatar, speech, brain and memory — and Selvia AI is several times cheaper per minute than LemonSlice, with a free tier LemonSlice doesn't offer.
Per-user memory
Selvia AI recognizes returning customers and recalls past conversations. LemonSlice treats every session as new — no memory of who came before.
Always-on kiosk mode
Selvia AI runs all day as an unattended kiosk and keeps working in noisy, crowded spaces. LemonSlice is built for web and app sessions, not continuous deployment.
Automatic emotion
Selvia AI's face responds to the conversation in real time, shifting expression to match the tone — with no manual scripting.
When LemonSlice is the better choice
LemonSlice is a promising platform with a genuinely different strength. If you want to turn a single photo into a talking avatar, its image-based avatars can look impressively lifelike. And if you want body gestures — waving, expressive movement — for creative or character content, that's a real capability Selvia AI doesn't focus on. Selvia AI is built for the other job: an all-inclusive, live conversational avatar that remembers people, runs all day, and ships complete and ready to deploy.
The bottom line
LemonSlice and Selvia AI are built for different jobs. LemonSlice shines at image-to-avatar and creative gestures. Selvia AI is built for live, always-on conversation that remembers your customers — and for that job it ships the avatar, voice, brain and memory in one $1/hour price, turnkey out of the box, at a fraction of the real cost.
