Find the Best AI Tools for Any Task

Founden is the engine for autonomous software. Describe the first version and it goes live. Leave it running and it keeps developing itself. Founden turns a plain-language description into a real, running company: the website, the app with sign-in, its back office, payments, email and its own domain, built and published by an AI builder (Claude Code or Codex). Switch on autopilot and the same AI keeps developing it: it ships improvements, answers the company's email and works on growth. Build in the browser or in the macOS desktop app on your own AI plan. Free to start with 200 credits; paid plans from $29 a month.

JevModel is an independent, bilingual guide and browser workbench for TypeSafe's Jev decision model, aimed at developers and product teams who need a judgment their code can act on. Instead of free-form prose, Jev returns a typed answer: one choice from a set you define, a score on a scale, or the probability that a statement is true. The Jev Workbench ships ten editable workflow presets covering support routing, lead scoring, agent action gating, incident triage, release readiness and more; edit the state and questions and run a real decision in the browser. Each account gets five free runs per UTC day plus a one-time 100K token grant. Thirty-plus guides cover the API, question types, access paths, comparisons with LLM prompts and rules engines, and evaluation.

Jev Model is a System One decision model for developers. It accepts shared state as text, JSON objects, or arrays of text and answers up to eight Choice, Score, or Noul questions in parallel, returning structured outputs with probabilities that applications can use for classification, routing, scoring, guardrails, and human-review workflows. The website provides a free unlimited online playground, documentation, API access, and paid access plans.
