What Powers Hana

Hana is a collaborative AI assistant designed to help teams stay organized, automate routine tasks, and surface the right information at the right time. Behind the scenes, Hana combines multiple intelligent components to deliver fast, relevant, and secure assistance without exposing sensitive implementation details.

Intelligent Core

Ensemble of Models

• Hana routes each request through a carefully orchestrated mix of large‑scale models.
• Specialized engines handle reasoning, creativity, factual recall, and visual understanding.
• Weighted voting and confidence thresholds ensure consistent, high‑quality outputs while guarding against hallucination.

Prompt & Instruction Hierarchy

• A layered prompt system maintains a strict chain of command: platform rules → developer guidance → user requests.
• Built‑in validation prevents user prompts from overriding system directives, preserving both reliability and security.
• Continuous guardrails scan inputs and outputs for policy compliance.

Knowledge Engine

Data Ingestion

• Accepts content from chats, documents, knowledge bases, and major business platforms.
• Text, audio, and images are normalized into a unified internal format.
• Premium tiers unlock enhanced parsing, including embedded‑image text extraction and advanced OCR.

Retrieval & Memory

• Hybrid search blends semantic vectors with keyword relevance, using rank‑fusion scoring for precise results.
• Automatic batch resynchronization keeps knowledge fresh while capping the number of sync cycles per organization to protect performance.
• Optional long‑term archives support compliance needs and high‑volume histories.

Conversational Layer

• Listens and responds within enterprise communication platforms (at the moment only Google Chat) in real time.
• Asynchronous follow‑ups allow Hana to deliver rich cards, documents, or images after initial text replies.
• Memory‑aware conversations maintain context across threads while respecting user privacy boundaries.

Action Framework

• Natural‑language commands trigger domain‑specific workflows (e.g., scheduling, data lookups, or project updates).
• Role‑based access controls ensure actions execute only where permissions allow.
• Custom actions can be introduced to extend Hana into proprietary systems - Coming soon!

Security & Compliance

• All data in transit and at rest is encrypted with industry‑standard protocols.
• Granular RBAC defines who can ingest, query, or modify organizational knowledge.
• System prompts, audit logs, and model outputs are monitored for policy violations.
• Privacy controls allow per‑organization retention policies and selective memory purging.

Reliability & Scalability

• Stateless request handling enables horizontal scaling across regions.
• Background job queues and retry policies ensure tasks eventually succeed even during transient failures.
• Health probes and telemetry feed into centralized monitoring for rapid anomaly detection.
• Built‑in safeguards limit resource‑intensive operations and prevent denial‑of‑service scenarios.

Extensibility

• Connector framework integrates with document stores, project trackers, and other enterprise tools without exposing credentials.
• Event webhooks and a REST interface let organizations build custom dashboards or automation on top of Hana’s services.
• Feature flags allow gradual rollouts and A/B testing across cohorts.

Support & Continuous Improvement

• Usage analytics and user feedback loops guide model selection and prompt tuning.
• Premium customers receive faster response times and advanced document‑processing features.
• Regular model evaluations and regression checks maintain quality as the platform evolves.
