● Introducing MemexOS Read the post ↗

MemexOS is building the default engine for memory and continual learning for agents.

Available through our API, plugins, and MCP.

COPY SETUP PROMPT

The path to useful AI is to scale in-context continuous learning that works with any model, any harness, and for all the varieties of use cases. As open-source model adoption grows and the world becomes even more multi-model, learning and memory should be separated from the model providers and be highly interoperable (hence in-context!).

Intelligence is no longer a constraint. ↗

Pre-training and post-training, scaling on data and compute, will continue to push models' intelligence, but will not enable them to learn and improve in real time.

We build all the hard infrastructure parts of a scalable memory system, with dense, interconnected, growing learnings, and an understanding of time.

Our model learner-1 helps any model continuously improve by extracting and dreaming on the context of any user, task, or tenant, and putting it on our vector-graph database. This is then brought to the model by injecting tokens into its context in real time.

What we do

Memory that keeps learning.

learner-1 extracts and dreams on the context of every user, task, and tenant, stores it in a vector-graph database, and brings it back to the model by injecting tokens into its context in real time.

Any model, any harness.

Learning and memory live outside the model providers, so they carry across models and harnesses and stay interoperable, in context, and yours.

The hard infrastructure, done.

Dense, interconnected, growing learnings with an understanding of time, already serving 100k+ organizations and over a trillion tokens a month.

Scale and Enterprise include advanced document extraction for PDFs, with OCR and descriptions of figures and diagrams. Free, Pro and Max keep standard PDF extraction. Explore document support.
