The Intelligent Foundation for
Sinhala Journalism and Writing
Empowering Sri Lankan newsrooms, editors, and writers with domain-adapted LLMs. Fine-tuned on authentic journalistic corpora with specialized LoRA adapters for grammar, headlines, style, and summarization.
ජනාධිපතිවරයා ඊයේ පැවති උත්සවයේදී නව ආර්ථික ප්රතිපත්තිය ප්රකාශ කළාය. රටේ සංවර්ධනය සඳහා සියලු ජනතාව එක්විය යුතු වේ.
✓Subject-Verb Agreement: 'ජනාධිපතිවරයා' (honorific) → 'ප්රකාශ කළේය' (corrected from feminine 'කළාය')
✓Morphological Case Alignment: 100% syntactic harmony validated

“SinAi is the first AI tool that genuinely understands the syntactic complexity of formal Sinhala grammar and news registers.”
“As AI models transform global media, preserving the syntactic beauty, cultural nuance, and journalistic integrity of the Sinhala language has never been more urgent. SinAi bridges deep linguistic heritage with state-of-the-art foundation intelligence.”
From newsroom deadline pressures to academic reporting, our mission is to empower journalists with AI tools that respect authentic grammatical rules and editorial registers.
Architected for linguistic precision and enterprise scale.
Behind SinAi is the Sinhala Journal LLM research foundation fine-tuned on millions of authentic Sinhala journalistic tokens, paired with high-throughput infrastructure.
LoRA Adaptation for Specialized Linguistic Tasks.
Domain-Adapted Sinhala Tokenizer
Standard tokenizers excessively fragment Sinhala unicode combining characters, multiplying token counts and degrading context. Our domain model preserves full morpheme integrity.
Zero-Degradation Hot Adapter Swapping
Our inference engine dynamically loads low-rank adapters in memory without reloading the base model, enabling sub-800ms switching between grammar, headlines, and style rewriting.
Length-Conditioned Executive Summaries
Abstractive compression trained with explicit length tokens to deliver concise 3-bullet executive briefs or detailed narrative syntheses without hallucination.
Newsroom-Grade Security & Row-Level Isolation.
Postgres Row-Level Security (RLS)
Every news draft, grammar check, and headline generation is strictly locked to the author's authenticated UUID. Isolation is enforced at the database kernel level, preventing any cross-journalist leaks.
Privacy-Preserving Hashed Telemetry
Anonymous callers are rate-limited via salted cryptographic hashes (`sha256(ip + salt)`). Raw IP addresses and article contents are never stored on unauthenticated sessions.
Reliable Model Gateway & Failover
Built-in automatic fallback routing between dedicated GPU clusters and secondary endpoints for high availability during breaking news cycles.

SinAi Web App
Writing Studio & Workspace
Benchmarked against generalist models.
Generic multilingual models frequently hallucinate Sinhala characters and fail subtle syntactic rules. Sinhala Journal LLM was designed to eliminate these limitations.

“SinAi was engineered with the conviction that native language newsrooms deserve the same high-caliber, domain-adapted AI intelligence available in major global languages.”
Asanka Mendis
Head of Editorial Systems, Media Lab
“SinAi has cut our breaking news headline drafting time in half while ensuring our grammar strictly adheres to standard national newspaper conventions.”
Nalinda Jayawardena
Editor-in-Chief, National Daily
“The ability to effortlessly decode legacy UBIN-encoded newsroom archives into Unicode while running instant syntactic corrections is a game changer for Sri Lankan journalism.”
Dr. Sanduni Perera
Computational Linguistics Researcher
“The 5-tone style engine lets our journalists rapidly adjust reporting for our print newspaper, broadcast teleprompter, and social channels simultaneously.”
