X Post Type Classifier

Extension

Label your X feed with Jev and dim selected post categories, including promotions and engagement bait.

S1 →Jev selects a post's primary intent from six categories using its text and author name. The extension handles viewport dwell detection, caching, inline badges and user-selected dimming. The current model request contains no image or video content.

robo-jev — Physical Judgment Model

Library / SDK

An independent 2B model for text-based physical judgments between robot planning and control.

S1 →It sits between task planning and low-level motion control, choosing actions such as continuing, slowing or stopping and judging collision, tipping, spilling or part-seating conditions. Each question uses a fixed prompt and reads answer-position probabilities into choice, noul or score outputs. It does not provide visual perception or replace motor controllers.

Game Harness Lab

App

A local game-agent workbench that tests and evolves Decision harnesses using gameplay feedback, GEPA and paired evaluations.

S1 →StartLux Decision chooses each gameplay action from the supplied action set. The published configuration uses think_mode=never. GLM-5.3 and GEPA improve harness instructions outside gameplay; host code enforces rules, validates choices and executes actions. These are StartLux Decision results, not verified runs of official TypeSafe Jev.

Decision Arena

App

Play against decision models, compare AI opponents, and share game replays across board and real-time games.

S1 →Jev, StartLux System One, or a compatible decision model selects the next action from candidates supplied by the game engine, using the current game observation and visible context. The engine handles rules, continuous physics, action validation, execution, and replay recording. Unknown or invalid choices stop the turn rather than being replaced with a random move.

ToS Decipher

Extension

Read policy highlights alongside their source passages in your browser.

S1 →Identifies policy links, assesses clause impacts, and uses typed questions to check whether generated conclusions are supported by source passages.

ToS Watch

App

Track changes in data use across terms of service and privacy policies.

S1 →Answers bounded classification questions about changed policy passages to help identify substantive changes; the program handles pages, caching, and email drafts.

Jev Inbox for Mailspring

Extension

Show urgent messages first in the currently loaded email list.

S1 →Jev assesses importance, urgency, and custom labels; the plugin uses the results to reorder the visible message list.

QuantDinger

App

Self-host a workspace from strategy backtesting to trade execution.

S1 →Jev assesses entries and risk from orders, strategies, positions, and budget state; code combines the judgments and decides whether to submit orders.

Jevort

Extension

Suggest reasoning effort for Pi prompts.

S1 →Jev selects from a finite set of reasoning-effort levels; code checks probabilities and maps the result to options supported by the current model.

ThoughtDAG

App

Branch conversations on a canvas and select relevant past context.

S1 →Jev optionally assesses topics and excerpt relevance to help choose historical context for the next turn.

Doom or Bloom

App

Explore views of AI futures through adaptive interviews.

S1 →Jev uses Choice, Score, and Noul to interpret answers and compare follow-up questions; the program handles routing, stopping, and presentation.

MinusPod

App

Self-host podcast ad detection and re-editing.

S1 →The System One adapter converts tasks such as ad detection into structured questions; the application controls editing, review, and subscription output.

treg

App

Centralize tool calls and run Jev workflows.

S1 →jev-memory uses Jev to identify lasting preferences sentence by sentence, then saves and reuses them in later sessions according to thresholds set in code.

Jev Drone

App

Choose a detour, climb, brake or target reacquisition while code handles flight control.

S1 →In the main experiment, ordinary code converts simulated depth and segmentation buffers into a scene. Jev chooses a maneuver with Choice, assesses risk with Score and judges whether the target is genuinely lost with Noul. Flight control, guidance and safety reflexes remain in code and can override its advice.
