Lawyeah — Polish law AI platform with document generator and law firm profiles
Lawyeah is our proprietary product — a legal-tech platform combining artificial intelligence with Polish law. ByteWave designs, builds, and develops this platform in continuous development mode. We offer six core legal tools in a freemium model, plus dedicated profiles for law firms and their clients. The entire platform runs on Next.js with custom AI integrations (RAG on data from official government databases) and dedicated connectors to various legal systems.
Client and context — ByteWave's own product
Lawyeah is ByteWave's own product — a platform we designed, build, and develop ourselves. This is not just a programming contract, but a strategic investment in the vertical legal-tech market in Poland. Our motivation was a market gap: the Polish legal market has limited AI tools, and most global legal-tech platforms (Harvey, Lexion, Casetext) focus on the English-speaking market and common law — making them unsuitable for Polish civil law.
From a business perspective, Lawyeah has three audiences: (1) citizens looking for quick legal answers without having to hire a lawyer for simple questions; (2) law firms looking for AI tools to streamline their work — case-law search, document analysis, generating template letters; (3) law firm clients who can access tools through their law firm.
The platform is in continuous development mode — every week we add new functionalities, optimise existing ones, improve AI models. There is no "final release" — Lawyeah is a living, evolving product that grows with user needs and legal developments.
The challenge
Building an AI platform for Polish law is an exceptionally complex project — combining advanced AI technologies (LLM, RAG, embeddings, fine-tuning), the specifics of Polish civil law (different from common law), accessibility requirements (the platform must be simple for citizens without legal education), and professional requirements (law firms need trustworthy tools for professional work).
The most serious technical challenge is the quality of AI responses in the context of Polish law. LLM models trained mainly on English-language data have limited knowledge of the Polish legal system. To get useful answers, we built our own RAG (Retrieval-Augmented Generation) system fed with data from official government databases — case law, legal acts, official interpretations. AI does not respond "from memory" but based on current, verified sources.
The second challenge is multi-model architecture — different tools require different AI models. Some tasks (classification, embeddings) use specialised models, others (legal reasoning, generating documents) — advanced models. We use several AI models in parallel, selecting the appropriate one for the task.
The third challenge is integrations with external systems. Lawyeah draws data from many official sources. For each source, we wrote our own integration API — no ready-made clients, no middleware, directly to API. This gives full control over data quality and response time.

Process — continuous development model
Lawyeah is not a fixed-deadline project — it's a product in continuous development mode that evolves with user needs. We work in 2-week sprints, delivering new features, optimising existing ones, integrating new data sources.
First phase — foundations
2024Creating the first version of the platform with two basic tools: AI Virtual Lawyer and Case-Law Search. First integrations with official databases. Scaling architecture.
Second phase — tool expansion
2025Adding more functionalities: Document Templates, Write a Letter generator, Check a Letter document analysis, Knowledge Base. Platform redesign for law firm profiles.
Third phase — law firms and paid model
2025-2026Introducing dedicated profiles for law firms with team and client management from one account. Implementing freemium model with limits in free version and full access in paid plan.
Fourth phase — ongoing
continuous developmentAI model optimisation, adding new RAG data sources, UX improvements, mobile app work, plans for integrations with law firm systems, expansion into more legal languages (Lithuanian, German).
Technical solution
Lawyeah is built in Next.js with TypeScript — a modern React framework with server-side rendering for performance, static generation for SEO, and serverless functions for scalability. TypeScript gives us type safety in such a complex application as an AI platform with many integrations.
The heart of Lawyeah's intelligence is the RAG (Retrieval-Augmented Generation) system. Instead of relying solely on "knowledge" built into LLM models, the system first searches for relevant documents (rulings, legal acts, interpretations) in our database fed from official government sources, then uses AI to generate the answer with that context. This provides several benefits: timeliness (database refreshed regularly), reliability (each answer has cited sources), accuracy (AI does not "hallucinate" law but interprets specific documents).
We use several AI models in parallel, selecting the appropriate one for the task. Classification and embeddings have a different optimal model than legal reasoning or generating letters. The architecture is agnostic — adding a new model requires configuration, not rebuild.
All integrations with external systems are our own dedicated connectors. Each data source has its own custom integration module — no ready-made clients. This gives full control over data quality, response time, and timeliness.
Why Next.js, not another framework?
Next.js combines best features: SSR for performance and SEO, serverless functions for scalability without server management, static generation for static pages, mature React ecosystem.
Why RAG instead of pure LLM?
Pure LLM responding "from memory" to questions about Polish law risks hallucinations, outdated information, and lack of citations. RAG solves all three.
Why freemium, not paid only?
Lawyeah has a mission: broad accessibility of law for citizens. Paid-only model would exclude those who need legal help most.
Why law firm profiles?
Individual users have different needs than professionals. Law firms need: team management, usage tracking, workflow integrations, larger limits.
Six tools and two profile types
Lawyeah is an "all-in-one" platform for Polish law — six tools in coherent whole plus two types of dedicated profiles.

Results
Lawyeah is a living legal-tech platform — in active use by both citizens and law firms. From a strategic perspective, it is our investment in the vertical Polish legal-tech market, which is dynamically growing with AI development.
From a technical perspective, the platform has scaling-ready architecture. RAG, multi-model AI architecture, custom API integrations — all designed for growing traffic and more data sources.
From ByteWave's perspective as an agency, the Lawyeah project plays two roles: (1) reference case for potential clients looking for a partner to build advanced AI/RAG applications, and (2) R&D laboratory — where we experiment with new AI models, RAG techniques, integration architecture, before applying them in client projects.
What's next — roadmap
Lawyeah is in continuous development mode. Near-term directions include: mobile app (currently in preparation — native iOS and Android app providing access to all tools on the go), integrations with law firm systems (Mecenas, Solectro, Optima — direct connection of Lawyeah tools with law firm workflow), and expansion to more legal languages (Lithuanian, German — countries where ByteWave has clients).
From an AI perspective, the roadmap includes: further optimisation of models and RAG (better performance, lower costs), experimentation with new techniques (chain-of-thought, agent-based reasoning), and adding new RAG data sources.
From a business perspective, the plan is further acquisition of law firms (B2B segment), expanding the product offer for them (more specialist tools), and potential geographic expansion with multi-jurisdictional tools.
"The biggest distinguishing feature of the site is the Virtual Lawyer powered by artificial intelligence. This solution is not only innovative but also very useful — it allows combining traditional legal knowledge with the latest achievements of AI technology."
