Advancing the frontier of AI systems with memory
Born out of the Sky Computing Lab at UC Berkeley, Letta believes that programming agents starts with programming memory. We build tools to help developers create, deploy, and manage AI agents at scale. Our platform offers a hosted cloud solution and an API, both designed for production applications backed by agent microservices with REST APIs. Letta adds memory to your LLM services to give them advanced reasoning capabilities and transparent long-term memory (powered by MemGPT). We offer a model-agnostic approach, allowing you to use your preferred LLMs and RAG systems. Our focus is on providing a white-box system for debugging and fine-tuning agents, empowering developers with control and transparency.
Personalized AI with long-term memory, self-editing memory, infinite context windows, access to unlimited data, customizable tools
Add your AI agent to our curated directory
Handle multi-step workflows autonomously
Example
Schedule meeting → Find time → Send invite → Confirm attendees
Save 5-10 hours/week on routine coordination tasks
Gather data from multiple sources and summarize
Example
Research competitor pricing across 5 websites, create comparison table
Reduce research time from hours to minutes
Analyze options and recommend actions
Example
Review 20 vendor proposals, score against criteria, rank top 3
Make data-driven decisions faster
AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.
Large language model for reasoning and decision-making
Understand tasks, plan steps, generate responses
APIs, databases, external services the agent can call
Take actions beyond text generation (search, compute, write files)
Short-term (conversation) and long-term (persistent) memory
Maintain context across interactions and learn from past actions
Decision engine for choosing next action
Plan multi-step workflows and handle errors/edge cases

Optimization Tips
Letta has been stable for production-ish demos; the explainx.ai page was a useful single link to share internally.
Letta is a strong agent listing on explainx.ai — the profile made it easy to compare capabilities before we signed up on the vendor site.
According to our evaluation, Letta benefits from clear positioning — fewer buzzwords than typical agent landing pages.

Solid agent profile: Letta links out cleanly and the on-site reviews add signal beyond marketing copy.
Letta has been stable for production-ish demos; the explainx.ai page was a useful single link to share internally.
Good discoverability: Letta shows up in the agents directory with enough detail to pre-qualify buyers.
We piloted Letta for two weeks; the registry summary and category tag matched what the product actually emphasizes.
We compared Letta with three neighbors in the same category; this one had the most concrete “what it does” framing.
