Section 01

Low-Code Workflow Platforms

Build AI-powered automations visually — no need to learn Python, LangChain, or any programming framework. Drag, drop, connect.

PlatformPricingSelf-Hosted?Best ForEU Notes
n8nFree (self-hosted), Cloud from €24/moTechnical users who want full control; 400+ integrationsCan be self-hosted on EU servers

Recommendation: Start with Make if you want ease of use with EU data residency. Move to n8n when you need more control.

Section 02

API Routers & Orchestrators

A single gateway to access multiple AI models. One API key, switch between models easily, and keep your data in the EU.

PlatformWhat It DoesPricingEU Compliance
EUrouterEU-sovereign AI routing; drop-in OpenRouter replacementPay-per-use🇪🇺 Data stays in EU
Requesty EU140+ models, zero cross-border transfer, Frankfurt-hostedPay-per-use🇪🇺 GDPR Art. 44, ISO 27001
EuqaiEU-native router with intelligent model selectionPay-per-use🇳🇱 Hosted in Netherlands
OpenRouterLargest model selection (200+)Pay-per-use⚠️ EU routing by request only
Why use a router? You avoid vendor lock-in, can compare models easily, and European routers keep your data within EU borders — important for GDPR compliance.

Section 03

Best AI Models by Task

You don't need the biggest model for every job. Here's what works best for common small business tasks, as of February 2026.

General Text (emails, summaries, content drafts)

Section 04

What Does AI Actually Cost?

Real examples with real numbers. Spoiler: it's probably less than you think.

🧩 AI API costs are measured in tokens (chunks of text). Rough guide: 1,000 tokens ≈ 750 words. A typical email is about 200–400 tokens.

Weekly Event Digest

Process 20 event descriptions, generate categorised summary

~$0.05/year
Using Mistral Small 3.2

Customer Email Summariser

Process 50 emails/day, generate daily summaries

~$3.60/year
Using Mistral Medium 3

Transcribe a 1-Hour Meeting

Whisper (self-hosted): Free
Deepgram Nova-3: ~$0.46/hr
OpenAI API: ~$0.36/hr

Free – $0.46
Depends on provider
Bottom line: For most small business use cases, AI API costs are negligible — often less than a coffee per month. The real cost is your time building and maintaining the workflows.

Section 05

Low-Code Web & App Builders

Need a frontend for your AI workflow? These let you create web apps, portals, and dashboards without coding.

PlatformStarting PriceBest ForConnects To
