Orrin

Available iOS · Web · Windows

Flagship · Agentic workspace

Spatial, agentic workspace for advanced notes (OrrinInfinity), planning, and running AI tools and agents - without constant prompting. Project-scale context carried through Exegesis sessions and memory.

  • Infinite canvas
  • Agentic tasks
  • OrrinSDK extensible

Yabble

Pre-beta (revamping)

Desktop · Host-machine agents

Desktop intelligence from what’s already on your machine and screen. Agentic tasks via Terminal Sessions, Exegesis-backed web browsing for minimal tokens, and multi-step loops held coherent by shared memory.

  • Terminal Session handlers on the host
  • Spec-backed web understanding
  • Sandbox-first with human override

Pragmos

Pre-beta (revamping)

Planning · Schedule · Journal

Plan, adapt, and execute without calendar ping-pong. Preferences and availability drive agent-to-agent coordination so schedules form from what people already want - then feed the rest of the Stellr stack.

  • Preference-driven planning
  • Agent-to-agent booking
  • Voice-native reconfiguration

Exegesis

Infrastructure

Protocols · Sessions · Memory

Not a consumer surface - the shared infrastructure under every Stellr product. Web specifications, realtime WebSocket execution, episodic memory, and interactivity contracts so context awareness is infrastructure, not a bolted-on feature.

  • .espec & ESPECI
  • Terminal Sessions
  • Contextual memory

Exegesis Web Spec

Spec layer

.espec · Endpoint semantics

Machine-readable endpoint semantics so models understand web surfaces without heavy scraping or oversized prompts. Dense structure replaces multi-hop REST reconstruction - inference spends budget on reasoning, not discovery.

  • Declare endpoint meaning once
  • Fewer tokens, fewer scrape loops
  • Shared contract across products
Web specifications

Specki

Spec layer

Specki · Live UI contracts

Declarations that let pages and tools react to user behavior in real time, feeding agents live situational context as work unfolds. Interactive web that informs models while users act - not after the fact.

  • Real-time behavioral signal
  • Pages that feed agent context
  • Situational awareness mid-flow
Interactivity specs

Surfaces on infrastructure. Specs under everything.

Orrin, Yabble, and Pragmos are product surfaces. Exegesis and its specification layers are the shared substrate - sessions, memory, and contracts so agents and tools compose instead of reinventing context plumbing.

Build on the same substrate.

Use OrrinSDK, Terminal Session handlers, and Exegesis specs - ship domain behavior, not transport plumbing.
