Absolute privacy for your most complex decisions. Hefty lives on your hardware. No cloud. No compromises.
Our Convictions
Not feature checkboxes the non-negotiables behind every line of code we ship.
Everything runs on your hardware. Your data stays on your machine — unless you explicitly choose otherwise.
Hefty works for you and no one else. No corporate agenda, no declined requests, no hidden data collection. You always have the final word.
Learns from every interaction. Remembers across sessions. Becomes genuinely more useful over time — without you configuring anything.
Watch every action as it happens. See exactly what Hefty does on your behalf — no blind spots, no hidden processes.
Connect any tool, API, or service. Your integrations become Hefty's capabilities instantly — no restarts, no friction.
Surfaces connections, risks, and opportunities before they land on your desk. Not just reactive — genuinely proactive.
What You Get
Works for you and no one else.
Your data. Your hardware. Your control.
No corporate agenda. No censored prompts. It connects to your services and executes on your terms — so you're free to focus on what matters.
Hefty lives entirely on your hardware. Your conversations, your data, your thinking — it's physically impossible for any of it to leave your machine.
It remembers how you like things done. The more you use it, the more it connects the dots across your projects — never explain yourself twice.
Hefty quietly surfaces a missed deadline, a connection you hadn't seen, or a shifting risk — before it costs you.
Analyze a sensitive deal. Draft a private document. You never have to wonder, "Is this safe?" — because it always is.
It learns the nuances of your work — your phrasing, your structures, your tools. Extend with plugins so it fits precisely how you operate.
Knowledge That Grows
Every task you delegate teaches Hefty something it retains — your preferences sharpen into instincts, your patterns become shortcuts, and your context deepens with every session.
No re-prompting. No starting over.
Every approach that works is captured and reused automatically — so you never solve the same problem twice.
Every mistake is learned from once and turned into a guardrail — steering you away from known dead ends before you waste time on them.
The people, tools, and projects you work with are remembered and woven together — so the right context is always there when you need it.
