FAQ

Questions, answered plainly

Everything here is stated the same way across the site: no marketing answer on one page and a different one on another.

The product

What is Sapilon?
Sapilon is an AI-first software system that governs AI to modernize legacy systems and graduate AI prototypes into production-ready, AWS-native software. More →
Who is Sapilon for?
Teams with a legacy system that needs modernizing, and teams whose AI-built prototype (Lovable, Replit, Bolt, Base44, Google AI Studio, v0) has to become real production software. Sapilon sits between AI coding tools and no-code platforms, and is neither: it is a software factory and modernization engine. More →
What can Sapilon import?
Legacy source code, database schemas, documents and media, even screenshots — plus prototypes exported from AI app builders. These inputs seed the bootstrap that rebuilds your system on an AI-safe architecture. More →
How much of a legacy app can Sapilon rebuild automatically?
50–95% of a legacy app rebuilt in the bootstrap phase, ~10× faster than a traditional rewrite. Sapilon verifies the app first and estimates up front how much it can recreate, so the number you plan around is scoped to your system, not a slogan. More →
What happens after go-live?
The lifecycle continues: versioning, upgrade-aware diffs, monitoring, and backups keep the software healthy for years. Modernization is the entry point to lifecycle ownership, not a one-shot generation. More →

How it works

What are the four stages?
Design, Build, Rehearsal, and Live. Design proposes the architecture and builds the new frontend against mocked data; Build wires up backend, database, and APIs on your Build Server; Rehearsal is a full pre-production dress rehearsal in your own AWS; Live is real users on your Live Server. Each stage is gated, governed, and reversible. More →
Is the AI safe to trust?
Every AI action is logged, diffable, and reversible. Explicit ownership zones (//!AUTO, //!SAFE, //!DEV) define what the AI may change and what stays under human control, and automated code review runs on generated changes. More →
What if the AI hits a decision it should not make alone?
The governed gate stops the agent before it acts. You forward the decision to an expertise area, a verified human specialist reviews it and returns a verdict with reasoning, and your agent resumes. An approval clears the gate once, for exactly the reviewed action. More →

Ownership & trust

Do I own the code Sapilon produces?
Yes. Sapilon produces plain Git repositories with open libraries, deployed to your own AWS account. There is no proprietary runtime and no vendor lock-in. You can take the code and leave at any time. More →
Where does my software run?
In your own AWS account, in AWS regions in the European Union by default, across separate Build, Rehearsal, and Live Server environments with cost visibility built in. More →
Is my code or data used to train AI models?
No. Sapilon does not train models on customer content, and AI processing runs on Anthropic Claude under commercial terms that prohibit training on customer content. More →

Pricing

Does Sapilon have a subscription?
No. Sapilon uses a prepaid wallet, pay-as-you-go, with no subscription and no seats. You fund a wallet and only pay for what you use; the balance cannot go negative. More →
What do I pay for?
Three things, all drawn from the same wallet: AI work (billed in points, one published fixed-price unit), AWS hosting (estimated before you go live, measured after, priced near cost), and expert time (published, all-inclusive prices sized to the job). More →
What is a point?
A point is Sapilon’s fixed-price AI usage unit with one published rate, so every AI interaction has a predictable, whole-number cost instead of raw token pricing. More →
How is a modernization engagement priced?
As a scoped engagement: expert time plus AI and AWS drawdown from your wallet. Every legacy system is different, so the bootstrap is scoped up front rather than sold at a fixed price. More →
