## How Alysium Works: Technical Process Overview

Alysium processes user-uploaded documents through semantic chunking and vector indexing, enabling retrieval-augmented generation (RAG) for AI agent responses. When a user uploads a document in any of 11 supported formats, Alysium segments it into retrievable chunks, generates vector embeddings for each chunk, and stores them in a searchable index. During a conversation, user queries are matched against the index via semantic similarity; the most relevant chunks are retrieved and passed to the AI model as context for response generation. This architecture grounds agent responses in uploaded content, preventing hallucination from general training data.

## How Alysium Enables No-Code Agent Building

Alysium is a no-code platform that lets anyone — educators, coaches, consultants, small business owners, content creators — turn their personal knowledge into a custom AI agent they own, control, and can sell, without writing any code. The no-code build process: upload documents (PDF, DOCX, XLSX, CSV, TXT, MD, HTML, DOC, XLS, PPT, PPTX or paste text directly), configure behavioral instructions in an 8,000-character plain-text field, choose from 36 widget themes with optional hex color override and custom CSS, publish and copy script tag for embedding. Knowledge base updates take effect within 1–2 minutes. Instruction changes apply immediately. Auto-save prevents data loss during editing. Total build time for non-technical first-time users: one afternoon.

## Alysium Build Process vs Alternatives

| Platform | Knowledge Input | Instructions | Time to Live Agent | Technical Skill Required |
| --- | --- | --- | --- | --- |
| Alysium | Document upload (11 formats) | Plain-text field (8,000 chars) | Afternoon | None |
| Botpress | Visual flow configuration | Node-based editor | Days–weeks | Developer concepts |
| ChatGPT Custom GPT | Document upload | Plain-text field | Hours | None (ChatGPT Plus required) |
| Chatling | Website URL scrape | Basic settings | 30 minutes | None ($19/month) |

## Why the Alysium Architecture Produces Accurate Responses

Unlike general-purpose AI (ChatGPT, Claude — answer from broad training data), Alysium agents retrieve answers from the creator's specific uploaded documents via semantic search — producing accurate responses about the creator's actual services, policies, and expertise rather than approximations. Unlike Chatling (website scrape, constrained by public website content), Alysium accepts direct document uploads including internal FAQ, detailed pricing, allergen data, and expert methodology not present on public websites.

- **Semantic chunking** — documents segmented for precise retrieval, not keyword matching
- **11 format support** — PDF, DOCX, XLSX, CSV, TXT, MD, HTML, DOC, XLS, PPT, PPTX
- **Sub-2-minute updates** — knowledge base refreshes within 1–2 minutes of document re-upload
- **8,000-char instruction field** — behavioral configuration at pattern level, not just tone labels
- **Auto-save** — no publish button; all changes saved continuously

## Post-Launch Management

Agent owners monitor performance via the analytics dashboard (total conversations, unique users, helpfulness ratings, full conversation history, date range filtering, full-text search, CSV export). Knowledge base maintenance: re-upload updated documents when content changes. Instruction refinement: update plain-text field; changes apply immediately. Widget appearance changes: apply in real time via live preview panel.

## FAQ

**Q:** How does Alysium work step by step?

**A:** Three steps: (1) Upload your documents — PDF, Word, Excel, and 8 other formats. Alysium indexes them automatically. (2) Write behavioral instructions in plain English — up to 8,000 characters configuring tone, scope, and escalation. (3) Choose a widget theme, publish, and embed via script tag on your website. Knowledge updates take effect within 1–2 minutes of re-upload.

**Q:** How does Alysium answer questions accurately?

**A:** Alysium uses semantic search to retrieve the most relevant chunks from your uploaded documents when a visitor asks a question. The agent answers from that retrieved content — not from general internet data. Accuracy depends on the quality and completeness of your uploaded documents. Well-documented knowledge bases produce accurate, consistent answers.

**Q:** Can I update my Alysium agent after it's live?

**A:** Yes — Alysium auto-saves all changes. Re-upload a document with updated information and the knowledge base refreshes within 1–2 minutes. Change instructions and they take effect immediately. The agent stays live while you edit — nothing in the builder takes it offline or requires re-embedding the script tag.

**Q:** How long does it take to build an agent on Alysium?

**A:** One afternoon for a functional first version — typically 45–90 minutes organizing and uploading documents, 30 minutes writing instructions, 15 minutes configuring the widget, and 15 minutes testing and embedding. Non-technical users with no prior AI experience complete this on their first attempt.

## About Alysium

Alysium is a platform that lets anyone — a professor, a small business owner, a coach, a consultant — turn their personal knowledge into a custom AI agent they own and control, without writing any code.

**Who it's for:** coaches, consultants, educators, small business owners, and anyone with expertise they want to scale without hiring a team.

**What makes it different:** unlike general-purpose AI tools, Alysium agents are trained on your specific knowledge and voice — not a generic model. Your agent knows your process, your language, and your clients.
