Overview
Mem0 and Mengram are both AI memory solutions, but they take fundamentally different approaches. Mem0 focuses on semantic fact storage with a large community. Mengram adds episodic and procedural memory types plus Cognitive Profile.

Memory types: the key difference
Mem0 stores facts (semantic memory) and has recently added graph memory for entity relationships. It does this well with a mature SDK and large community (40K+ GitHub stars).
Mengram stores three distinct types: semantic (facts), episodic (events with context), and procedural (workflows that evolve). This means Mengram agents don't just remember what you told them — they remember what happened and how to do things.
Cognitive Profile
Mengram's unique feature is Cognitive Profile — one API call generates a complete system prompt from a user's entire memory. Mem0 requires you to manually search and assemble context.
API comparison
# Mengram
from mengram import Mengram
m = Mengram(api_key="key")
m.add("conversation text", user_id="u1")
results = m.search("query", user_id="u1")
profile = m.profile(user_id="u1") # unique to Mengram# Mem0
from mem0 import MemoryClient
client = MemoryClient(api_key="key")
client.add("conversation text", user_id="u1")
results = client.search("query", user_id="u1")
# No equivalent to profile()When to choose Mem0
Mem0 is a strong choice if you need: the largest community and ecosystem, SOC2-compliant enterprise deployment, graph-based fact storage, or are already invested in their tooling.
When to choose Mengram
Mengram is better if you need: episodic and procedural memory, self-improving workflows, Cognitive Profile for instant personalization, or a free tier with all features. See the full comparison page.
