Modify the web.
Add what is missing to the sites you use, or build a complete app that is always available in your browser.
One Mod can add a panel, layout, calculation, or action directly to a live page. Another can open as a full browser app for SEO analysis, content review, project work, source control, or any focused workflow you create.

Missions
Give an autonomous workflow a scoreboard.
Missions measure performance across every run, then use the evidence to improve the workflow over time.
Define the KPI, target, source of truth, cadence, and action boundary. Moxby compares results, preserves what works, identifies drift, and evolves the operating plan toward the outcome.

Token Condenser
Restore the context. Reduce the repeated weight.
Context Rasterization and condensed tool outputs help supported model calls carry eligible context with fewer tokens.
The transcript stays stored as text. Recent instructions and exact strings stay textual or are retrieved from text. Usage Reporting shows measured savings so plan allowances are never presented as guaranteed results.
