AI, explained for real small businesses (not buzzwords).
This page is a practical overview of modern AI (especially “chat” AI / large language models). You’ll learn what AI is, what tokens are, when GPUs matter, the top ways small businesses use AI, and how to think about security, storage, and retention — plus a simple guide to equipment and rough setup costs for cloud and on-prem.
What is AI?
“AI” is a broad term for software that can recognize patterns, make predictions, or generate outputs (text, images, summaries, recommendations) based on data it was trained on. The most common AI small businesses touch today is a Large Language Model (LLM) — the engine behind chat-style assistants.
AI is not magic (and that’s good)
AI can be confidently wrong
AI doesn’t “know your business” by default
AI adoption is mostly process + permissions
Tokens (what they are, why they matter)
A token is a small chunk of text the AI reads and writes. It’s not exactly a word. Rough rule of thumb for English: 1 token ≈ 3–4 characters or ~0.75 words. Tools often bill and limit usage by tokens (input + output).
Token limits (a.k.a. “context window”)
Why tokens affect speed + cost
Token estimator
Quick estimate: enter a word count. This is a rough educational tool (not billing-accurate).
Do you need GPUs?
Not always. Many businesses use cloud AI (you log in and use it) with no special hardware. GPUs matter when you want local/on-prem AI, heavy automation, or you need to process large volumes quickly.
Cloud AI vs Local AI (simple view)
Local AI: more control over data flow, can be offline, but requires hardware, updates, security hardening, and monitoring.
Other “things needed” beyond GPUs
- Identity & access: SSO/MFA, role-based access, audit logs.
- Data classification: what’s allowed (public/internal/confidential/regulated).
- Knowledge base: approved SOPs, policies, product sheets (ideally searchable).
- Process: review/approval steps for customer-facing output.
- Security controls: DLP, endpoint protection, phishing defenses, least privilege.
AI tool stack (common in small business)
Most “AI at work” is a combination of these building blocks:
1) Assistant / Chat AI
2) Document search (RAG)
3) Automation / Workflow tools
4) Safety layer
Equipment & rough cost to set up an AI system
These are rough ranges. Costs swing based on user count, automation scope, and compliance. For most small businesses, cloud is the quickest ROI; on-prem is for tighter data control or offline needs.
Cloud-based AI (most common)
Best for: fast deployment, minimal IT overhead, scaling up/down.
What you need
- Business accounts (admin controls, MFA/SSO if possible)
- Normal PCs (no special GPU needed)
- Stable internet
- Policies + training (what data is allowed)
- Optional: document search/RAG + workflow automation
Typical cost ranges (rough)
- Light usage: commonly tens of dollars per user/month for “assistant” plans.
- API usage: variable costs based on tokens and volume (good for custom workflows).
- Setup help (optional): 4–20+ hours for policy, permissions, templates, testing.
On-prem / local AI
Best for: tighter control of data flow, offline use, or predictable heavy usage.
What you need (equipment)
- GPU workstation/server (GPU VRAM is the biggest limiter)
- CPU + RAM (serving, indexing, concurrency)
- Fast storage (NVMe SSD recommended)
- Firewall + VLAN segmentation (restrict who can access the AI box)
- Backups (configs, prompts, knowledge base, logs)
- Monitoring + patching (security updates and uptime)
Typical cost ranges (rough)
- Entry local AI box: often $1,500–$4,000.
- Mid-range workstation/server: often $4,000–$10,000+.
- Operational: power + cooling + IT time.
- Setup time: commonly 10–40+ hours for hardening, access, testing, monitoring.
Quick cost “menu” (simple breakdown)
| Approach | What you get | Typical starting costs (rough) | Ongoing costs |
|---|---|---|---|
| Cloud — Basic | Chat assistant for drafting, summaries, templates | Low Mostly per-user subscriptions |
Monthly per-user + optional token/API usage |
| Cloud — + RAG | AI answers using your approved docs (knowledge base search) | Low–Moderate Indexing + setup |
Monthly storage/indexing + usage |
| On-prem — Entry | Local model for internal drafting + limited knowledge base | $1.5k–$4k Starter workstation |
Power + maintenance + IT time |
| On-prem — Mid/Server | More users, faster responses, more storage, redundancy options | $4k–$10k+ Hardware varies heavily |
Power + cooling + patching + monitoring |
Tip: for most small businesses, Cloud Basic → Cloud + RAG is the best progression. On-prem is a “because we must” choice.
Top common uses for AI in small business
Pick an area to see what AI can do, what to watch for, and a few starter ideas. (Tip: start with internal drafts first — it’s the safest, quickest ROI.)
Customer Support & Service
Quick wins (starter ideas)
Prompt library (copy/paste)
You are helping a small business. Draft a clear, friendly first version. Context: [paste internal notes here] Goal: [what you want] Constraints: - Keep it under 200 words - Use simple language - Include a short checklist at the end
Write a customer-facing reply. Customer message: [paste message] Company policy: [paste approved policy excerpt] Rules: - Do NOT invent promises, pricing, or timelines - If details are missing, ask 2-3 clarifying questions - End with a friendly next step
Summarize these notes into: 1) Key decisions 2) Action items (with owners + due dates if stated) 3) Open questions Notes: [paste notes here]
Where AI helps most (rule of thumb)
Best ROI is usually work that is: repeatable, text-heavy, low-risk, and currently eats time.
Security: what to worry about (and what to do)
The big risk isn’t “AI becomes evil.” It’s people + data flow: pasting confidential info into tools, granting overbroad access, or auto-sending unreviewed outputs.
Golden rules for staff
- Never paste passwords, MFA codes, private keys, or full credit card numbers.
- Avoid regulated data unless you have an approved, compliant tool + policy.
- Minimize: share only what’s needed (redact names/IDs if possible).
- Human review before sending customer-facing AI output.
- Use business accounts (SSO/MFA, logging) — not random personal logins.
Where information can leak
Controls that actually help
- MFA + SSO for AI accounts
- Role-based access (who can upload docs? who can export?)
- Data Loss Prevention (DLP) rules where possible
- Logging + review (especially for automations that send messages)
- Approved knowledge base (one source of truth)
How information is stored & retained (what to ask vendors)
Different AI products have different settings. Don’t assume. The safe approach is: treat prompts and uploads like business records unless proven otherwise.
What might be stored
- Chat history (your conversations)
- Uploaded files/documents
- System logs (timestamps, user IDs, IPs, device info)
- Safety logs (abuse detection / policy enforcement)
- “Improvement/training” usage (sometimes optional/disabled in business tiers)
Retention questions to ask (copy/paste list)
- Can we disable training/model improvement on our data?
- What is the default retention period for chats and files?
- Can we set retention (30/90/365 days) or delete on demand?
- Is data encrypted in transit and at rest?
- Do you support SSO/MFA, audit logs, and admin controls?
- Where is data stored (region), and how is access controlled?
- How do you handle subprocessors and third parties?
Vendor security checklist (interactive)
Quick Start: roll out AI without chaos
1) Start with low-risk wins
Pick 1–3 tasks that are internal, repeatable, and measurable.
- Draft customer emails (human review before sending)
- Summarize meetings into action items
- Turn notes into SOPs and checklists
- Categorize and tag support tickets
2) Define what data is allowed
Create simple rules your team can follow.
If you’re in a regulated industry, use a vetted, compliant solution and keep written proof of settings.
3) AI readiness checklist
4) Document your policy (template)
A short policy beats “everyone does whatever.” Use the button below to download a draft you can edit.
Make sure the policy matches your tools and retention settings.
