Graph database built on object storage for agent memory and context
Graph, WAL, value, and index data all live in S3-compatible storage with a hot/warm/cold tiering strategy, cutting infrastructure cost dramatically versus memory-resident graph databases.
One query can traverse graph relationships and run vector, BM25, and reranked search together, so agents do not have to orchestrate four separate systems.
Every change is tracked, letting agents recall what happened, when, and in what sequence, which supports auditability and long-running agent workflows.
OpenCypher over Bolt plus an HTTP API and SDKs make it approachable for teams already familiar with property graphs.
A general-purpose AI agent that executes tasks, not just answers them
Give the agent a goal and it plans the steps, chooses tools, and works through the task in a cloud environment without constant supervision.
Produces finished artifacts such as slide decks, functional websites, small games, and formatted documents rather than raw text.
Runs broad, multi-source investigations and compiles the findings into a structured report.
Generates images, video, and music as part of a larger task or as standalone outputs.

#1Features advanced computer use and interactive artifacts, but operates primarily as a chat assistant rather than a dedicated autonomous agent platform.

The AI workspace where teams and agents get work done together

Executes tasks using cloud virtual Linux machines, but focuses more on personal desktop automation than complex multi-app research.
Free / Open-sourceProvides open-source personal task automation, but lacks the polished cloud sandbox environment of Manus.


Automates multi-step workflows and asset creation, but with fewer built-in general browser navigation tools.
SpecialistConverts prompts into structured office deliverables, but acts primarily as a document generation workspace.

Free / Open-sourceUnites multiple models and custom agents in a self-hosted workspace, but lacks pre-built autonomous execution sandboxes.
SpecialistDeploys autonomous business agents for operational work, but targets enterprise workflows rather than general open-ended research.
The managed vector database and knowledge engine for production AI
SpecialistDeploys agent fleets to build business deliverables, but requires more manual setup for complex web research.

A memory and continual-learning engine that gives any AI agent persistent context
