Nullstep is an AI-powered anti-procrastination workspace for solo founders. Describe a goal in plain language and it generates a prioritized execution path that syncs straight to a Kanban board, wrapped in a deliberately minimal interface.

Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.

Nullstep is an AI-powered anti-procrastination workspace for solo founders. Describe a goal in plain language and it generates a prioritized execution path that syncs straight to a Kanban board, wrapped in a deliberately minimal interface.
Type an objective in plain language and the AI returns a prioritized Execution Path with ordered tasks, priority levels and time horizons.
Generated tasks land on your Kanban board automatically, so your plan and your working list never drift apart.
A single dashboard holds your tasks, AI sessions and decisions so you stop tab-switching between half a dozen tools.
Every session is saved automatically, so you can return tomorrow or from your phone and continue exactly where you stopped.

Open WebUI is an open-source, self-hosted AI interface that lets individuals and organizations run any model — local or cloud — inside a workspace they fully control. It ships as a one-command install, supports Ollama, OpenAI-compatible and Anthropic endpoints, and extends through Python tools, functions and pipelines.
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
