So you don't have to

Two engines. You choose.

Local mode answers before you finish reading the question — fast, free, and completely private. Smart mode brings in cloud AI when you hit something complex — you choose when, every time.

Stone Engine (Local)

Default on all tiers

Answers in under 100ms — faster than you can type the question
Your financials, client names, and strategy stay on our servers — never shared
Unlimited messages — no surprise bill at the end of the month
70B parameter model — the same class of AI that powers enterprise tools

Best for: daily brainstorming, sensitive client work, running up the score without watching the meter

Smart Mode (Cloud)

Opt-in on Builder+ tiers

Cloud AI for the questions that stump everything else — contracts, analysis, strategy
You choose per message — cloud only fires when you pull the trigger
Daily cap means no runaway costs — your budget stays exactly where you set it
Credit packs for crunch time — big pitch week, product launch, tax season

Best for: investor decks, legal reviews, competitive analysis, anything that needs the sharpest mind in the room

1

Sign up free

Google, Apple, Outlook, Yahoo — pick your login. No credit card, no forms. You're chatting with 4 AI agents before your coffee gets cold.

2

Chat locally

Ask anything — the agent thinks through angles, weighs options, and delivers the answer before you finish the thought. Your data never leaves our network.

3

Add Smart mode

Hit a wall? Flip on Smart Mode for the heavy stuff. You pick when. You control the cost.

Enterprise

Healthcare, finance, legal — we built for you

Patient records, financial models, case files — they stay on our network by default. Cloud mode only activates when you say so. Your compliance team will love the audit trail.

Contact Sales

More speed. More intelligence. Your call.

Every tier puts more specialists in your corner and more hours back in your week. Start free, scale when the results speak for themselves.
