Detailed source capsules
Student text, selected images, and imported files are stored locally under stable source IDs before any long-term inference.
What actually happenedPROVENANCE-FIRST AI MEMORY
Memory should explain
why it knows you.
PRISMS AI does not treat a conversation dump as a student profile. It stores detailed source capsules first, derives bounded conclusions second, and recalls only the evidence a current task needs.

THE MEMORY PIPELINE
Detailed source capsule → incremental profile → precise recall.
Each layer has a different job, storage boundary, and failure behavior. Profile maintenance never blocks an unrelated student request.
Incremental personal profile
A profile agent folds durable preferences, goals, recurring needs, communication style, and explicit uncertainty into bounded claims.
What remains usefulOn-demand evidence
A business agent receives a compact relevant profile and retrieves an exact detailed source only when more support is needed.
Only what this task needsPER-CLAIM MEMORY QUALITY
A conclusion is never stronger
than its sources.
Lineage
Every durable claim points to supporting source capsules. Unsupported legacy claims are removed or marked for review—not assigned invented references.
Freshness and conflict
Each claim carries freshness, confidence, supporting evidence, conflicting evidence, and a recommended review action.
Non-blocking maintenance
The last validated profile remains active while new capsules are compressed through durable background work.
MULTIMODAL AND PRIVATE
Images and personal knowledge
become local evidence.
User-selected images receive local Vision OCR, classification, capture metadata, dimensions, and a content digest. Personal knowledge is chunked and hybrid-indexed on the phone with lexical and semantic signals.
LIVEIMAGE MEMORY
Labels do not become profile claims by themselves.
Local scripts persist and audit image evidence; the profile agent decides whether that evidence supports a durable conclusion.
LIVEPROACTIVE MEMORY
Grounded suggestions, never silent action.
A Today Tip can combine authorized memory, reminders, calendar, and device facts. It cites supporting facts and requires confirmation before action.
