Every feature built with one purpose: making Hefty work better for you. Your data, your control.
We're refining the experience based on what early users tell us — fixing, improving, listening. Your feedback directly determines what we build next.

Hefty doesn't rush in — it understands your situation, recalls what it knows, builds a plan, executes, and learns from the outcome. Not just an assistant. A thoughtful one.
Hefty builds three kinds of knowledge from every interaction: reusable techniques (skills), mistakes to avoid (antipatterns), and facts about your tools and projects (entities). Skills track their own reliability — proven ones rise. Knowledge stays scoped per project.
Hefty reads and writes files, browses the web, opens apps, and takes screenshots. You never pick which capability to use — its cognition pipeline selects the right instruments. If something fails, it reads the error and adapts automatically.
Run AI entirely on your own hardware with Ollama or LM Studio — free, private, and nothing ever leaves your machine. Or connect to a cloud provider if you prefer. You pick, you test, you switch at any time.
Nothing happens without your say-so. Hefty asks when it needs clarity, checks before anything risky, and always gives you the final word — keeping you in control, always.
Share images and files with Hefty just like you would with a trusted colleague. It sees your screenshots, analyzes documents, and works with whatever you send — and it all stays on your machine.
Connect external MCP tool servers, point Hefty at any HTTP API, define custom AI tasks as reusable prompts, or install third-party plugins — their capabilities become instruments the moment they're connected. No restarts needed.
You decide exactly what Hefty can access and do on your computer. Nothing more, nothing less.
Connect Hefty to email, messaging, and other services — so it can reach you wherever you work.
Shape how Hefty communicates — its tone, its style, its approach — so it feels genuinely like yours.
Track milestones, see how Hefty keeps getting better, and watch your productivity grow.
