What you need to know
This page stands alone. No previous AI knowledge is required. You need access to an AI assistant only for the activity.
Learning outcome: By the end, you will choose a tool category from the information, privacy and certainty involved.
Before you begin: Do not upload sensitive material merely to test a service. Check its current privacy terms first.
The lesson
There is no single best visual AI service. Build a small toolkit rather than an allegiance.
Product names and features change. Choosing the right category is the durable skill.
Cloud services may offer stronger models; on-device services may offer greater privacy, offline use or control.
Five useful categories
- Conversational image describers for photographs, objects and scenes.
- Text and document recognition for exact wording, forms and structure.
- Multiple-model comparison for stronger evidence than one description.
- Private or on-device processing for sensitive material or offline access.
- Human visual assistance when accuracy, judgement or consequences require it.
Choose according to the job
- Do you need an overview, exact text, structure or judgement?
- How sensitive is the image?
- What would happen if the answer were wrong?
- Can you operate the service comfortably with your access method?
Try it
For a social photograph, bank letter and medicine label, choose a tool category and explain why. Then use the Tool Cards to compare current services.
Checkpoint
Your choice changes when exact text, privacy, accessibility or consequences change.
