Simple by design

Memory that works like yours.

Three steps. Your agent learns, remembers, and naturally forgets what it no longer needs.

Bars show memory strength — full when recently created or recalled, fading as it ages unused.

How much would you save?

Two ways to find out — a 30-second check inside your AI, or a full breakdown from your own history.

Instant audit 30 sec

Paste this at the end of any session — Claude, ChatGPT, Gemini, Cursor, Copilot. It needs no knowledge of YourMemory; your AI measures and compresses the conversation itself.

Comparison

Not a vector database.

Vector stores hoard chunks and never forget. YourMemory keeps memory that strengthens, fades, and connects — like yours.

Legacy · vector DB

Stores chunks. Returns chunks. Each session starts from zero — and nothing is ever prioritized or forgotten.

YourMemory

Facts that evolve. Knowledge that merges, decays, and connects across every session — so only what matters survives.

Enterprise

Memory that works across your whole team.

Your team accumulates deep knowledge every day — customer quirks, solved problems, architectural decisions. Right now it evaporates when the session closes. Enterprise gives it a permanent home.

Team memory sharing
Your Memory A Alice shared B Bob shared C Carol shared D Dan shared E private Eve F private Shared memory Private memory
Without YourMemory

Engineer A spends two hours debugging a customer edge case. Session closes. The knowledge is gone — and Engineer B starts from scratch next week.

// Session ended context = null customer_hist = null team_knowledge = null
With YourMemory Enterprise

Engineer A solves it once. The memory persists, shared with the org, and surfaces automatically when Engineer B opens a session — solved in minutes.

// Session opened recall("customer edge case") → 3 relevant memories surfaced → last solved: 6 days ago by alice

Memory Browser · Audit Trail

Every memory, on the record.

A built-in Memory Browser shows every stored memory with its live strength, category, and recall history — and an Audit tab logs every read, write, and delete to a tamper-evident hash chain. Switch tabs in the panel to explore both.
