What is Persnally?
Persnally operates entirely on the user's device by importing data from various AI sessions and repositories. It converts this information into evidence-linked events and derived views that represent interests, preferences, and past choices. The system serves this context to compatible tools at the start of each session, allowing agents to reference prior details immediately. Users retain full control through features like selective scoping for different clients and the ability to erase specific topics with automatic rebuilding of related data. Provenance tracking ensures every element of the profile links back to its source events, supporting transparency and verification without external dependencies.

What you can use Persnally for
Cross-Tool Context Sharing
Persnally feeds learned user details from past AI interactions to multiple tools so the same stack, conventions, and preferences do not need re-explanation each time.
Local-First Personal Modeling
A daemon on the user's machine converts imported chats, code, and decisions into a structured, evidence-linked profile that remains under local control.
Scoped AI Access Control
Users set per-client permissions so each connected AI receives only the allowed portion of the stored context.
