Frequently asked questions

Answers before and after you buy.

The product

Is Pauhu Fusion an AI model?

No. Pauhu Fusion is a deterministic Model Context Protocol (MCP) compiler. Your coding assistant reads your repository and decides what a request needs. Pauhu composes code from cited operations and published standards; the same request returns the same result every time. The only AI in the workflow is your own assistant.

Does my code leave my machine?

No. Your assistant holds the repository and sends only the bounded context a request needs. The entire repo never crosses to Pauhu. The compiler runs in the EU and returns the composed code and a receipt.

Does Pauhu replace my coding assistant?

No. Pauhu complements your assistant. It composes cited code so your assistant can focus on intent and composition. Your assistant still performs the natural-language to code step and handles any gaps.

Is Pauhu an agent that can run code on my machine?

No. It is not a general chatbot or agent. It does not replace a senior engineer, does not browse your files, and cannot run commands. It composes cited code and returns it to your assistant.

How does Pauhu compare to context-trimming tools?

Context-trimming tools reduce the data sent to an LLM by heuristically selecting relevant files. Pauhu deterministically composes the requested operation from cited sources. It does not guess or summarise your repository; only bounded context crosses the wire.

Coverage and correctness

What does Pauhu compose?

Pauhu composes code for common operations across files, strings, data, and the web, against published standards and library APIs, and the library keeps expanding. It never invents an API: every line traces to a cited source.

What about code Pauhu has not composed yet?

Your own assistant handles it exactly as it does today, seamlessly. Pauhu never returns fabricated output, and the receipt shows which calls Pauhu composed at no token cost.

Does Pauhu guarantee correct code?

No. Pauhu composes code deterministically from published sources, but it does not guarantee the composed code is bug-free, secure, or suitable for your task. You are responsible for reviewing, testing, and validating the output before production use.

Why does Pauhu cost no tokens?

The deterministic composition does not call a model or perform GPU inference. If you then send the composed context to a separate LLM of your choice, that provider pricing applies to that part. Pauhu s receipt records both paths.

Connect and use

How do I connect my client?

Pauhu is a remote MCP server at https://mcp.pauhu.dev. You need an API key issued at checkout. On clients like Claude Code, VS Code Copilot, Cursor, or Codex you add the server URL and Bearer token; examples are on For developers. Setup takes a few minutes and needs no plugin install.

Can I use my own AI assistant?

Yes. Pauhu sits in front of the AI you already use. You can keep or swap your copilot; the compiler is the same and your repository stays in your tool.

Can I run Pauhu offline or self-host it?

Currently Pauhu Fusion is a hosted service at mcp.pauhu.dev and is not available as an on-premise or offline deployment. Your repository stays local, but the composition happens on the hosted server. Self-hosting may be considered later but is not offered today.

Are there rate limits?

Yes. The subscription is for ordinary individual or team development use. Fair-use and rate-limit rules are published in the Acceptable Use Policy; sustained automated abuse may lead to throttling or suspension.

Is there a service-level agreement (SLA) or support?

As of June 2026 there is no published uptime SLA. Status for the MCP endpoint and website is on the status page linked from Community. Support is by email at hello@pauhu.ai. Paid support or priority SLAs may be introduced later.

Pricing, billing, ownership

What does it cost and can I cancel?

A flat 279 EUR per user per month. Billing is month to month, with no annual lock. Cancel anytime via the billing portal; access continues until the end of the paid period. A free trial lets you see your savings before the first charge.

Is there a free trial?

Yes. A free trial lets you connect your client and see the savings on real work before any charge. If you do not cancel during the trial, the subscription begins automatically.

How do I cancel or get a refund?

Cancel anytime via the billing portal; access continues until the end of the paid period. Because the subscription is month to month, partial months are not normally refunded; charges made in error will be refunded. Consumers in the EU/EEA may have a 14-day withdrawal right.

Is there a team or enterprise plan?

The service is licensed per user at a flat monthly price. For larger teams or enterprises needing purchase orders, Stripe Invoicing supports B2B and B2G invoicing at the same price. Volume discounts or private deployments are not currently advertised; contact us for custom arrangements.

Who owns the composed code?

You own the composed code and may use, modify, and distribute it subject to the licences of any cited sources. Pauhu retains all rights in its corpus and engine. Provenance markers may be removed for production use, but you must comply with upstream licences.

Trust, privacy, compliance

Does Pauhu comply with GDPR?

Yes. Pauhu AI Ltd is the data controller and processes account data, request payloads, usage receipts, and truncated IP addresses as described in the Privacy Policy, under contract and legitimate-interest legal bases. Your repo does not leave your tool. Composition runs in the EU; the only sub-processors are Hetzner (hosting, Finland) and Stripe (payments, USA). Exercise your GDPR rights by emailing dpo@pauhu.ai.

What about the EU AI Act?

The compiler is a deterministic tool that composes code and does not learn or make automated decisions about users. The imprint states it is not an AI system within Regulation (EU) 2024/1689. Because it does not train or adapt, it does not fall under high-risk AI obligations. Any AI in your workflow is your own assistant under its provider terms.

How is the service hosted and secured?

The compiler runs in Hetzner s Finnish data centre. Requests are transmitted over TLS. Only bounded context is sent; your repository stays in your tool. API keys can be rotated and revoked. The DPA lists sub-processors and locations. Pauhu does not currently publish SOC 2 or ISO 27001 attestations but follows GDPR and implements technical and organisational measures.

Do you use any third-party scripts or trackers?

No. The site uses no external or third-party scripts. Cookie usage is limited to strictly necessary storage and the payment provider. There are no advertising or analytics trackers.
