Chrome extension that drafts on-brand social comments in one click
The extension reads the specific post before writing, so drafts reflect that content instead of a generic template.
Tell it how you write and it aims for your tone or your brand's tone rather than a neutral AI register.
Choose what the comment should do, such as agree, disagree or add insight, and how it should sound.
It works as a browser extension layered on the platform and never asks for your login credentials.

Self-hosted AI workspace for local and cloud models
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.
