What is AppIn?
AppIn is an AI-powered semantic search and chatbot for websites and online stores. It understands what your customers mean — intent and typos — across 100+ languages, including true cross-language search, so shoppers find the right product even when their words don't match your catalog. Built for ecommerce, tourism, real estate, and business sites, AppIn is EU-hosted (Germany) and GDPR compliant.
Built for your industry
Every search experience is individually configured with custom AI prompts tailored to your catalog, your customers, and your business goals.
E-commerce
"summer dress for a garden party"
AI understands occasion, season, and style — finds products even without exact keyword matches in descriptions.
Tourism & Travel
"quiet beach hotel for couples, no kids"
AI filters by vibe, amenities, and guest profile — shows exactly what travelers mean, not just what they type.
Sports & Federations
"basketball games in Berlin next week"
AI understands sport, location, and timing — finds upcoming events, results, and team schedules instantly.
Real Estate
"3-bedroom with balcony near a park"
AI understands layout, location preferences, and lifestyle — matches properties beyond keyword filters.
Healthcare
"orthopedist nearby, accepts TK insurance"
AI matches doctors by specialty, location, and insurance — patients find the right care faster.
Legal
"labor dispute precedents 2024–2025"
AI searches across case law, regulations, and legal documents — finds relevant precedents by context, not just keywords.

Frequently asked questions
Do I need a developer?
For standard search — no. Our WooCommerce plugin is live now (public beta) and works out of the box; other platforms use a simple API, with more integrations on the way. For a chatbot or custom document search, there is no coding either — we work with you to tune the AI to your business.
What makes this different from Algolia or Elasticsearch?
They rely on keyword matching. We use AI that understands intent and context — meaning and synonyms, not just exact words — across 100+ languages.
Is my data safe?
Yes. We're an EU-based company (Estonia), fully GDPR compliant. Data encrypted at rest, per-client isolation, query logs auto-delete after 3 months. We never share or use your data for training.
What languages are supported?
We support 100+ languages natively — English, German, French, Spanish, Italian, Estonian, Ukrainian, Chinese, Japanese, and more. Your customers search in their language, AI understands.
