Who it's for

One stack. Three jobs to be done.

Use Prompt Studio on its own to ship better AI work. Use Advi Agents on its own to capture leads from your existing website traffic. Or use both — they share a workspace, billing, and audit trail.

For students & researchers01 / 03

Write better with structured prompts.

Stop wrestling blank ChatGPT prompts. Twelve guided fields turn essays, literature reviews, and study notes into publication-quality output on the first try.

For marketing, sales & ops teams02 / 03

One shared workflow. Every output on-brand.

Save your voice, ICP, and constraints once. Every teammate produces output that reads like one company — outreach, briefs, ad copy, SOPs.

For service businesses & SaaS03 / 03

An AI sales rep that doesn't sleep.

Embed one script tag. The agent answers buying questions, qualifies intent, captures contact details, and routes hot leads across web, WhatsApp, Telegram, Messenger, and Instagram.

Why it matters

Most AI tools are demos. These are working tools.

Built by an operator running real lead-generation campaigns — not researchers chasing benchmarks. Every feature here exists because we needed it on a client engagement first.

01 / 04/feature

Structured beats freeform

Twelve fields — goal, audience, role, constraints, format, examples — turn vague AI requests into reliable, repeatable output. The same prompt works the same way every time.

02 / 04/feature

One script tag, full lead capture

Embed the widget in five minutes. The agent answers visitor questions from your knowledge base, captures email and phone, and routes hot leads to your CRM, Slack, or webhook — all without a developer.

03 / 04/feature

No code. No ML team. No fine-tuning.

Built for marketers, founders, and operators — not engineers. A working agent or prompt workflow ships in under ten minutes. Choose your model, write your persona, paste your knowledge.

04 / 04/feature

EU-hosted, GDPR-compliant by default

Data lives in Supabase Frankfurt. Authentication via Clerk with SCCs for US transfers. Server-only secrets. Standard DPA available for B2B engagements. No telemetry, no data resale, no surprises.

How to start

Three steps. About ten minutes.

No demo call required. No sales process. Self-serve sign-up takes you from credit-card capture to a working prompt or live agent before lunch.

01step

Sign up for the 7-day free trial

Create an account in thirty seconds. Pick Pro (€19/mo) or Team (€99/mo). Card captured for the auto-renewal — no charge until day 8, cancel any time during the trial.

02step

Build your first prompt or agent

Prompt Studio guides you through twelve fields and picks the right framework. Agent setup is a four-step wizard: identity, model, knowledge, channels. Both designed for non-technical operators.

03step

Ship and measure

Copy the prompt into your AI client of choice, or paste the agent's one-line embed script on your site. Watch analytics, refine, and re-run. The dashboard shows every conversation and every metric that matters.

The agency engagement

Need leads, not just tools? We run the campaigns end-to-end.

Advi Systems started as a Cologne-based lead-generation agency. The products grew out of running real client engagements. If you want us to handle acquisition — research, channels, copy, agents, optimisation — that is the agency service. Both products are bundled in at no extra cost.

01agency

Free access included

Active lead-generation engagement clients get Prompt Studio and Advi Agents at the full Team feature set — no extra cost, no usage caps. We use these tools on your campaigns anyway.

02agency

Methodology, not templates

Every engagement starts with niche, market, and buyer-behavior research. The campaign is built around what we find — outreach, channels, copy, agents — not pulled off a shelf.

03agency

Multi-channel from day one

Web widget first, then WhatsApp, Telegram, Messenger, Instagram — wherever your buyers already have conversations. Same agent, same knowledge, same dashboard.

04agency

Customer satisfaction is the only metric

Conversion dashboards are inputs, not goals. The work is done when the client says it was worth it. Quarterly reviews on every active engagement.

Common questions

What people ask before they pay.

Q.01

Why use this instead of ChatGPT?

+

ChatGPT is great for one-off conversations. It does not give you (a) repeatable team workflows, (b) a lead-capture agent on your website, or (c) GDPR-compliant data residency. Prompt Studio adds structure so every teammate produces consistent output. Advi Agents puts a working sales rep on your site. Both are EU-hosted by default.

Q.02

Why use this instead of Intercom or Drift?

+

Intercom and Drift are billed by seat (often €99–€200 per agent per month) and built primarily for customer support. Advi Agents is built for lead capture — qualify visitors, route hot ones, escalate to a human — at €19/mo for three agents on Pro or unlimited on Team. The two products share one workspace, so prompt engineering and lead capture sit on the same account.

Q.03

Do I need a developer to install the agent?

+

No. You copy one HTML tag — <script src="…" defer></script> — and paste it before your closing </body> on any site, CMS, or builder. It loads in under fifty kilobytes, supports custom colours and icons, and updates instantly when you edit the agent in the dashboard.

Q.04

Is the free trial really free?

+

Yes. Every paid plan starts with a 7-day free trial. We capture payment details so the subscription can start automatically on day 8, but you are not charged during the trial. Cancel any time during the seven days and you pay nothing. There is also a 30-day money-back guarantee on the first paid month if you change your mind after the trial ends.

Q.05

Where is my data stored, and what about GDPR?

+

Your product data is stored in Supabase, Frankfurt region (EU). Authentication is handled by Clerk, with EU Standard Contractual Clauses governing the US transfer. LLM requests route via OpenRouter to the model you choose, with zero-retention configuration where the provider supports it. A standard Data Processing Agreement (DPA) is available for B2B engagements — see the Privacy Policy for the full sub-processor list.

Q.06

What's the agency engagement plan?

+

Advi Systems started as a lead-generation agency. If we run lead acquisition for your business — strategy, channels, copy, agents, optimisation — both products are unlocked at the full Team feature set as part of the engagement, free, with no usage caps. The plan is admin-assigned only; you cannot self-subscribe to it.
