## Alethea (ALETHIA AI)

Alethea is a research and development studio working at the intersection of generative AI and blockchain, and it now presents itself under the brand ALETHIA AI. Its core proposition is presence: interactive avatars that have a face, a voice, and a personality, and that see, hear, and respond in real time. Instead of static scripts or text chatbots, the platform is built for spoken, face-to-face sessions that feel like a live conversation with a person.

The product is organized around a few clear surfaces. Practice sessions let individuals and teams rehearse the conversations that matter in their field, with avatars trained on real-world scenarios and every session scored against explicit evaluation criteria. The Academy packages in-demand skills into cinematic lessons led by AI tutors that give spoken, real-time feedback. For organizations, real-time video agents combine the AI engine with a scalable intelligence framework so agentic workflows can handle operational needs at volume.

A third strand targets creators and brands: characters with a living presence that can turn fan interaction into a live, face-to-face exchange. Alethea also points to contributions to open source, and offers a direct route for teams that need API access. Because pricing is not published, commercial terms are arranged through a demo or call.

**Pricing & Plans:** Pricing is not published on the website. Alethea / ALETHIA AI uses a contact-for-pricing model, with demos, calls, and direct outreach for API access and enterprise deployments.

- **Interactive Avatars:** Give an AI a face, a voice, and a personality that sees, hears, and responds in real time, turning scripted exchanges into genuine live conversation.
- **Scenario-Based Practice:** Rehearse the conversations that matter most in your field using avatars trained on real-world scenarios, with every session scored against explicit evaluation criteria.
- **The Academy with AI Tutors:** Learn in-demand skills through cinematic lessons paired with spoken, real-time feedback from AI tutors.
- **Real-Time Video Agents:** Combine the AI engine with a scalable intelligence framework to run agentic workflows that fit your operational needs.
- **Creator and Brand Characters:** Ship living characters that interact with fans face-to-face, making every audience touchpoint a live moment.

**Strengths:** Genuinely real-time, spoken interaction rather than text-only chatbots; Scoring tied to explicit evaluation criteria makes practice measurable; Covers both learning (Academy) and enterprise (API) needs on one stack; Backed by an active R&D studio that also contributes to open source

**Limitations:** No published pricing, so costs require a sales conversation; Some site sections (for example the Academy path) returned 404 during review; Blockchain-linked positioning may not suit every buyer

## SpatialReal

SpatialReal tackles the two things that usually make digital humans impractical in production: latency and cost. Instead of streaming rendered video from the cloud, it renders the avatar on the user's device, which brings response time below 300 milliseconds, drops bandwidth to 10–15 KB/s and cuts compute cost to roughly a hundredth of a typical cloud video avatar. The result is a photorealistic character that reacts, listens and breathes in real time rather than playing back stiff animation.

The platform is aimed squarely at developers. Web, iOS and Android SDKs are available on every tier including the free trial, alongside simple APIs for integrating into existing voice agents and conversational stacks. Because it is designed for interruption and adaptive dialogue, avatars work in live settings — customer support, sales onboarding, recruiting interviews, tutoring and interactive characters — not just pre-scripted demos. SpatialReal reports over 10 million interactions processed on the platform.

Pricing runs on credits. The free trial gives 500 credits a month — about 50 avatar minutes or 4 agent minutes — with 2 concurrent sessions and a watermark. Paid tiers step up from Starter ($19/mo, 22,000 credits) through Build ($99/mo) and Scale ($299/mo) to Accelerate ($999/mo), with per-minute rates falling as volume rises. Enterprise offers custom volume and concurrency with a dedicated contact.

**Pricing & Plans:** Freemium with credit-based plans. Trial: free, 500 credits/month (~50 avatar min or ~4 agent min), 2 concurrent sessions, 10-minute cap, watermarked. Starter $19/mo (22,000 credits), Build $99/mo (120,000), Scale $299/mo (400,000), Accelerate $999/mo (1,400,000); annual billing saves 20%. Avatar minutes from ~$0.0086 to $0.0071/min and agent minutes from ~$0.1036 to $0.0856/min depending on tier. Enterprise pricing is custom on request.

- **Sub-300ms real-time interaction:** Avatars respond in under 300 milliseconds, so conversations feel immediate rather than delayed, and they keep listening, reacting and breathing while waiting for the user.
- **On-device rendering, low bandwidth:** Rendering happens on-device instead of streaming video from the cloud, which cuts bandwidth to 10–15 KB/s and compute cost to roughly one hundredth of typical cloud video avatars.
- **Cross-platform SDKs and API:** Web, iOS and Android SDKs plus simple APIs let developers integrate digital humans into existing apps and agent stacks without a heavy backend.
- **Customisable AI presence:** Appearance, behaviour and voice can be tailored to your brand or AI experience, with natural, controllable motion rather than stiff scripted animation.
- **Built for live, interruptible dialogue:** The platform is built for interruption, reaction and adaptive dialogue, so users can talk over, pause and redirect the avatar naturally.

**Strengths:** Sub-300ms latency makes real-time conversation feel natural rather than laggy; On-device rendering slashes bandwidth to 10–15 KB/s, so avatars work on ordinary connections and devices; Around 1/100 compute cost versus cloud video avatars reduces scaling expenses significantly; Identical SDK coverage (Web, iOS, Android) on the free trial and all paid plans

**Limitations:** Credit-based pricing with separate avatar and agent minute rates takes some arithmetic to forecast real monthly cost; The free trial caps you at 500 credits, 2 concurrent sessions and 10-minute sessions with a watermark; Agent-mode minutes are roughly twelve times the cost of avatar-only minutes, which matters for long-running voice assistants; Session duration limits and concurrency rise only at the higher paid tiers
