The memory runtime for agents that live longer than a context window.

Kept keeps everything an agent experiences, then returns only the part of its life worth loading now, with the original evidence attached.

Recall

Ask the demo agent about its past. Every bid you see is the one that made the choice.

Inspect

The hierarchy is an index; every line opens down to the raw events.

Forks

Same life, different memory. Four clones of one agent, fed the same future; only the memory policy differs.

Developers

Send Kept everything your agent experiences. Ask it what matters now.

from kept import Kept

memory = Kept(agent="my-agent", api_key=KEY)

memory.remember({"type": "tool_call",
                 "content": "Deployment failed with authentication error."})

context = memory.recall("What happened the last time deployment failed?",
                        budget=3000)

answer = agent.run(task=current_task, memory=context.text)

memory.credit(context, success=True, used=context.event_ids[:1])

SDKs, one file each with no dependencies: Python · JavaScript · MCP server (Claude and any MCP client) · tool definitions for OpenAI and Anthropic function calling. The demo agent answers recall and credit without a key; your own agents get a key each, and a key reaches only its own agent.

get a key

Keys are invite-only while Kept is in preview. Leave an email and one line on what your agent does, and a key will come to you.

Research

Generated lifetimes; the numbers are what the run printed.

The benchmark is running.
