## TESIGN TAKE

This is not a finished app but a layer you put underneath other AI tools, so the value lands with developers fixing the "my agent keeps forgetting" problem.

## WHY IT MATTERS

An agent forgets once the window closes. MemOS is the layer that stores that memory and pulls it back when needed, handling knowledge bases, multi-modal material and tool memory through the same interface.

## BUILD FROM THIS

- Apache-2.0, exposing one unified API for store, retrieve and manage. Connected to DeepSeek Harness it adds automatic recall, background capture, hybrid retrieval and a local Memory Viewer.

## WHO IT'S FOR

- Developers building agents or support bots, and teams that need internal material remembered and queried.

## START IN 5 MINUTES

```
# Read the getting-started guide at memos.openmem.net and follow the example that wires it into an agent you already run.
```

## CAVEATS

- A developer-facing component — not something you install and use as a finished app.

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
