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
- Short-lived signed URLs
Vision-capable AI
Bring the screenshot into the conversation.
AINA securely stores supported images, verifies ownership, and gives the selected vision model only a short-lived signed link 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 credit enforcement
- Image-analysis weight
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
