Browser & OS Action MIT E2 · source reviewed

A Chrome ad-filtering extension that uses Jev to assess promotional intent in feed elements.

JEV · Decision point

Batches candidate DOM elements for TypeSafe and uses Noul probabilities with thresholds to decide which to collapse.

Adds text-based semantic judgments alongside local ad rules.

Decision Tools MIT E2 · source reviewed

A browser extension that classifies YouTube caption segments with Jev, splitting requests when the segment or token budget is exceeded, paints five categories on the seek bar, and auto-skips those painted slices over the threshold.

JEV · Decision point

One Choice per caption segment among content, sponsor, intro, outro, self_promo, recap, and other. Painted categories sponsor, self_promo, intro, outro, and recap skip when probability is at or above the threshold; content and other never skip.

Works on videos nobody has labeled yet; with no captions it does nothing.

Jev Trip is an explainable day-trip planner. The LLM plans ahead; Jev chooses and checks. Deterministic code handles route facts, time calculations, validation, and versioning.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

Data & Search MIT E1 · source linked

Jev answers multiple-choice questions and does not generate text, so on its own it cannot return a name, an email address or a quote. jeveryword numbers the words of your text, offers those numbers as the answer options, and converts the numbers Jev picks back into the original substring with its character offsets.

Data & Search MIT E2 · source reviewed

A record-linkage tool that asks Jev whether candidate records refer to the same entity under an explicit user-defined matching rule, then resolves links in code.

JEV · Decision point

Jev judges whether two candidate records refer to the same entity under a user-supplied match definition; local code generates candidates and resolves accepted matches.

Separates blocking, pair judgments, thresholded resolution and manual audit samples so missed candidates and wrong judgments can be investigated separately.

Codebase & Graph Pathfinding MIT E2 · source reviewed

Adds Jev-based selection before an existing test runner using diffs and test source.

JEV · Decision point

Jev judges relevance; local policy runs tests on uncertainty, API failure or changes to the test file itself.

Supports shadow-mode comparison, but selected subsets cannot guarantee complete regression coverage.

Routing & Cost Optimization MIT E2 · source reviewed

An OpenCode orchestrator that keeps a cheap sticky parent model and, when Jev flags a hard turn, escalates through a child subagent.

JEV · Decision point

Scores task, reasoning, and tool complexity, then chooses fast / balanced / strong / long; local policy stays, escalates, or fans out.

Keeps a cheap sticky parent model and opens a stronger child only when Jev flags a hard turn.
