Test retrieval quality on your own information, including access restrictions and outdated documents. Confirm deletion, retention, indexing updates, embedding costs, and how the application handles missing evidence.
What to do next
Write down what you need
Choose one task you need help with. Connect AI agents to persistent context, knowledge graphs, and vector retrieval. Note who will use the tool, what a good result looks like, and anything it must connect to.
Try the same task in each tool
Pick two or three options and give them the same example. Try a normal task and a difficult one. Record the result, any corrections, and how much time the work takes.
Check the cost and important limits
Ask specific questions before paying. For Letta: Test retrieval quality, deletion behavior, access boundaries, and retention. Compare hosting and embedding costs for your data. Check the same requirements with the other options, including access, exports, and the price of the plan you need.

- Make sure you can export your work if you leave.
A long feature list does not show how well a tool works for your task. Choose using the results of your own test.
