Public beta · v1.6.1

The first memory routing layer for AI.

MEMStorage sits between you and ChatGPT or Claude. Repeated questions are answered instantly from memory at zero token cost. Only genuinely new questions reach the model. Same answers. A fraction of the bill. Gemini support shipping next. Patent pending.

Three-tier routing
Memory hit · 20-token confirmation · full inference. Decided per query, in milliseconds.
Works where you work
ChatGPT and Claude today. Gemini and API drop-in (OpenAI / Anthropic) coming next.
Your data stays yours
Memories live in your namespace, never pooled. Deletable any time.
See it in action

Three match tiers. One UX.

Every prompt routes through MEMStorage first. If it matches a prior answer — exactly, lexically, or semantically — you get the response instantly at zero token cost. If not, the model runs as normal. You always have the option to override and send to ChatGPT anyway.

Tier 1 · Exact match
MEMStorage answering 'what color is the sky' from memory with an exact match
The same question you asked before. Served from memory in milliseconds. Zero tokens billed.
Tier 2 · Lexical match · 60%
MEMStorage answering 'can fitness help depression' by matching 'can fitness improve depression' from memory
Different wording, same intent. "Help" vs. "improve" — overlap detected, answer reused.
Tier 3 · Synonym match · 100%
MEMStorage answering 'is working out good for your mind' by semantically matching 'does exercise help mental health'
"Working out" = "exercise." "Your mind" = "mental health." Pure semantic understanding.

Every card shows the actual UX you'll see on ChatGPT and Claude. You always know it came from memory, you always know how it matched, and you can always override.
