Mengram: The Open-Source API Giving AI 'Human-Like Memory,' a Free Mem0 Alternative
2026-02-20 | Product Hunt | Official Site | GitHub
30-Second Quick Judgment
What is it?: It adds "memory" to AI Agents—not just remembering facts, but also events and workflows, so the next time it faces the same task, it takes the optimal path immediately.
Is it worth watching?: Yes, but manage your expectations. This is a project by a 22-year-old indie developer from Kazakhstan. The concept is excellent (the three-tier memory architecture is backed by academic theory), but the product is very early. If you're looking for a memory solution for your Agent, it's worth putting on your evaluation list; if you need production-grade stability, Mem0 is more mature.
Three Questions That Matter
Does it matter to me?
Who is the target user?:
- Developers building AI Agents/Chatbots
- Teams that need AI to remember context and learn workflows
- People using frameworks like LangChain, CrewAI, or Claude Desktop
Is that me?: If you are doing any of the following, you are the target user:
- Building AI apps that need to "remember the user" (customer service, assistants, copilots)
- Frustrated that your Agent starts from scratch in every conversation
- Wanting your Agent to automatically learn the best path instead of restarting every time
When would I use it?:
- Scenario 1: You built an AI customer service bot, and when the user returns the next day, it has to ask for their name again --> Use Mengram's Semantic Memory to remember the user profile.
- Scenario 2: Your Agent has to figure out the steps every time it deploys --> Use Procedural Memory to remember successful workflows.
- Scenario 3: You just need a simple chat history --> You don't need this; just use the LLM's native context window.
Is it useful to me?
| Dimension | Benefit | Cost |
|---|---|---|
| Time | Agent doesn't have to re-learn, saving time on workflow debugging | Learning the 3 memory concepts + API integration, ~1-2 hours |
| Money | Completely free, saving $19-249/month compared to Mem0 | Self-hosting requires server costs (PostgreSQL + pgvector) |
| Effort | One API call replaces a complex RAG pipeline | Early product; documentation and community are still sparse |
ROI Judgment: If you don't have a memory solution yet, spending 2 hours to try it is totally worth it—it's free, after all. If you're already using Mem0 and it's stable, there's no immediate need to switch.
Is it exciting?
What's the 'Wow' factor?:
- Procedural Memory is the real highlight: After an Agent completes a task, Mengram automatically saves the steps. Next time it hits a similar task, it goes straight to the optimal path. Did it fail? It automatically evolves to a new version. 3+ successes? It creates a new workflow. This is literally "AI learning."
- Cognitive Profile: One API call returns a system prompt fused with all three memory types. Just drop it into any LLM's system prompt for zero-cost personalization.
Real User Feedback:
"Mengram's positioning is more important than it looks. In 2024-25, AI was about 'generating good output.' In 2026, it's about 'consistently generating the right output for this company, this user, and this scenario'—and that requires memory." — UIComet Industry Analysis
To be honest, the product is so new that there are almost no real user reviews on Twitter or Reddit. This is both a risk (unverified) and an opportunity (early adopters have more influence).
For Developers
Tech Stack
- Backend: Python + PostgreSQL + pgvector
- Deployment: Railway
- Search Engine: Vector + BM25 + graph expansion + LLM re-ranking (4-layer search)
- SDK: Python (
pip install mengram-ai) + JS/TS (npm install mengram-ai) - Protocol: MCP Server (connects directly to Claude Desktop, Cursor, Windsurf)
Core Implementation
Mengram's core logic stems from three memory classifications in cognitive science:
- Semantic Memory—Stores facts. "User is named Xiao Ming, uses Python, lives in Hangzhou." Similar to a traditional RAG knowledge base.
- Episodic Memory—Stores events. "Last Wednesday, Xiao Ming discussed the new feature with the PM and decided on Option B." Includes timelines, participants, and outcomes.
- Procedural Memory—Stores workflows. "Steps to deploy to production: 1. Run tests 2. Build 3. Push 4. Verify." Includes success/failure counts and version evolution.
When searching, Unified Search queries all three types simultaneously. The Cognitive Profile then packages these into a system prompt to be injected into the LLM.
There are also three autonomous Agents:
- Curator: Automatically cleans up contradictory info (e.g., if a user changes their email, the old one is invalidated).
- Connector: Discovers hidden relationship patterns.
- Digest: Generates weekly memory summaries.
Open Source Status
- Fully Open Source: Apache 2.0, GitHub repo alibaizhanov/mengram
- Self-Hostable: Yes
- Similar Projects: Mem0 (Apache 2.0, 41K Stars), Letta/MemGPT, OpenMemory, MemOS
- Build Difficulty: Medium. The core is PostgreSQL + pgvector for storage, plus an LLM for extraction and ranking. The hard part is the classification logic and self-improving workflows. Expect 1-2 person-months for an MVP.
Business Model
- Monetization: Currently free; the founder is designing a freemium model.
- Pricing: $0 (Competitor Mem0 charges $19-249/month).
- User Base: Not disclosed; 103 votes on PH.
Giant Risk
High. This space is being watched closely:
- OpenAI already has native Memory features.
- Anthropic Claude is exploring memory layers within the MCP ecosystem.
- AWS just chose Mem0 as the exclusive memory provider for its Agent SDK.
- However, Mengram's "three-tier memory" and workflow learning are unique differentiators; giants usually build more generic solutions.
For Product Managers
Pain Point Analysis
- Problem Solved: AI Agent "amnesia"—starting every conversation from zero and failing to accumulate experience.
- Severity: High-frequency essential need. As Agents move from toys to tools in 2026, "memory" is the key bottleneck for production.
User Persona
- AI Developers: Building Agents on LangChain/CrewAI needing persistent memory.
- AI Product Teams: Wanting chatbots/copilots to remember user preferences.
- Power Users: Heavy AI users who want Claude/ChatGPT to truly "know them."

Key Takeaways
- The "Three Memories" Narrative: Dividing memory into facts/events/workflows is very intuitive. If you're building an AI product, use a similar cognitive science framework to organize features.
- Cognitive Profile: An API that returns a ready-to-use system prompt—this "zero integration cost" mindset is worth emulating.
- Self-Improving Workflows: Agents shouldn't just remember; they should "learn." This narrative is a level above simple "memory storage."
For Tech Bloggers
Founder Story
- Founder: Ali Baizhanov
- Age: 22
- Location: Almaty, Kazakhstan
- Background: Bachelor's from Al-Farabi Kazakh National University; Data Engineering at Bank CenterCredit, Software Dev at Prime Source, AWS Certified Expert.
- Why build this?: As an indie dev, he saw the success of Mem0 ($24.5M funding) and Supermemory but felt they only handled "fact memory," missing "event" and "workflow" memory.
This is a classic "Central Asian indie dev takes on Silicon Valley VC-backed project" story. At 22, alone, he used Python + PostgreSQL to build a memory architecture that is conceptually more complete than Mem0.
Discussion Angles
- Angle 1 -- Open Source vs. VC Route: Mem0 took $24.5M (YC + Peak XV), while Mengram chose to be free and open-source. Can open-source win the AI memory war?
- Angle 2 -- Feature Richness vs. Production Verification: Mengram's feature list is longer than Mem0's, but it lacks independent benchmarks. Is more features always better?
- Angle 3 -- Almaty vs. Silicon Valley: Supermemory's founder got Google exec funding at 19; Mengram's founder is 22 in Almaty. Can tech prowess bridge the geographic gap?
Hype Data
- PH Ranking: 103 votes, 2 comments (just launched)
- Twitter Discussion: Almost none; founder @BaizhanovB has low activity.
