01
Private by default
The upload bucket is private. Attachment records are scoped to their owner and cannot be reused across another user’s conversation.
- PNG, JPEG, and WebP
- File and count limits
- Ownership checks
- Validated inline model input
Vision-capable AI
Bring the screenshot into the conversation.
AINA securely stores supported images, verifies ownership, and gives the selected vision model only validated, bounded image data for the request.
02
Capability-aware routing
An attached image becomes a server-derived vision requirement. Smart Select chooses an eligible vision model; manual incompatible choices receive a clear alternative.
- No client capability trust
- Vision alternatives by friendly name
- Plan and allowance enforcement
- Relative image-analysis usage
03
Context preserved
The user message keeps its attachment record so the conversation remains understandable after reload, while broken assistant turns stay out of future model context.
- Signed history previews
- Conversation association
- Safe retry behavior
- Account deletion cleanup
