YAKKL® Wallet™ protects digital assets for people with real value at risk. YAKKL® Meridian™ turns serious AI work into plans, artifacts, audits, and finished delivery. YAKKL® Ari™ brings the same intelligence into embeddable product surfaces with controlled execution, budgets, and developer-defined policy.
Why YAKKL®
YAKKL® Wallet™ protects digital assets for people with something to lose. YAKKL® Meridian™ makes AI work durable enough to inspect, reuse, and govern after the session ends. YAKKL® Ari™ brings that intelligence into embedded product surfaces.
Operating Spine
YAKKL® Wallet™ proves the trust model. YAKKL® Meridian™ proves the execution model. YAKKL® Ari™ carries the same controlled intelligence into the apps builders ship.
Ari can provide a guided AI experience, AI chat, and more across many multi-AIs like Anthropic, OpenAI, and Google Gemini, but it's not an external Chat bot with a window like the way we know it today. It's a guided experience that can be embedded into any app.
YAKKL® Wallet™ provides different levels of security and AI access for different tiers. The tiers are Explorer, Guardian (most popular), and Sovereignty. YAKKL Wallet also provides a Wallet Engine for apps to embed if they need wallet functionality, but doesn't want to build their own wallet engine from scratch.
Multi-agent, multi-vendor workflow with planning, routing, memory, audits, history, and rerunnable delivery paths that implements the Rhumb Workflow Protocol™ (open source) for greater portability and inspectability.
Blogs, newsletters, audio, video, docs, scans, and a content system that can feed product learning loops.
Primary Products
Start with YAKKL® Wallet™ for custody and risk, YAKKL® Meridian™ for durable AI Workflow™, or YAKKL® Ari™ for embeddable intelligence inside an app.
YAKKL® Meridian™ turns any AI request into plans, artifacts, audits, and finished work.
YAKKL® Ari™ is the embeddable AI engine for apps that need controlled execution, developer-defined budgets, and multi-model routing.
YAKKL® Wallet™ is a security-first self-custody wallet for people with real value at risk. Explorer stays direct. Guardian adds protection. Sovereignty is the private-preview path for higher-risk holders.
Open Standard
Rhumb Workflow Protocol™ defines how AI-assisted work becomes durable: intake, plans, state, handoffs, schemas, and audits. YAKKL® Meridian™ is YAKKL's reference implementation of that protocol.
Plans, state, handoffs, and artifacts stay in plain files so serious work can move across people, agents, tools, and vendors without losing context.
YAKKL® Meridian™ follows Rhumb Workflow Protocol™ to turn requests into Master Plans, route work across models, preserve evidence, and keep execution inspectable after the session ends.
Rhumb Workflow Protocol™ can be adopted independently. Meridian™ packages that discipline into a product for builders and teams that want the workflow, orchestration, and governance handled.
