claude — no memory

$ claude "Use the auth pattern from last week"

I don't have context from previous sessions.
Could you share the pattern you're referring to?

$ claude "Remember, we decided on JWT with refresh"

I'll use that approach. Note: I won't remember
this in our next conversation.

Every session starts from scratch

claude + memstalker

$ claude "Use the auth pattern from last week"

Found in memory: JWT + refresh token pattern
from session Mar 12. Applying to your current
auth middleware...

✓ Applied. 3 files updated.

Source: sessions/2026-03-12-auth-refactor.md

Context persists across every session

[memory:recall] query="auth pattern" → 3 results (12ms) → top: sessions/2026-03-12-auth-refactor.md (score: 0.94)

the problem

Every conversation starts from zero.

Context amnesia

Paste the same background into every new chat. Watch your AI ask questions you’ve answered ten times.

Model lock-in

Switch from Claude to ChatGPT? Start over. Your context is trapped in one platform’s memory.

Zero continuity

Your AI doesn’t know what it learned yesterday. Every session is a blank slate.

getting started

Three commands. Permanent memory.

01

Connect your sources

Link your Obsidian vault, upload files, or connect GitHub. Memstalker indexes everything with AI-powered classification.

memstalker ingest ./obsidian-vault

✓ 847 documents indexed

✓ AI summaries generated

✓ Full-text search ready

02

Connect your AI models

One command per model. Claude Code, ChatGPT, Gemini — all reading from the same brain.

# Claude Code

claude mcp add memstalker -- npx memstalker-mcp

# ChatGPT — import Custom GPT Action

# Gemini — add MCP config

03

Build with memory

Your AI agents now share context. What Claude learns, ChatGPT remembers. Across every session, every model.

$ claude "continue the API refactor from yesterday"

✓ Found 3 relevant sessions

✓ Resuming from commit a3f8c2d...

capabilities

Built for how developers actually work.

Bidirectional Teaching

You teach your AI with corrections and documentation. It teaches you back with ELI-5 explanations and pattern recognition. Both sides get smarter every session.

Self-Learning Loops

Every mistake, correction, and fix gets captured with context. Your AI learns from failures and never repeats them. Intelligence that compounds.

Token-Optimized Retrieval

Not markdown dumps — an AI-optimized database. FTS5 + semantic search returns precisely what’s relevant in 8ms. Your AI gets better context with fewer tokens.

Private & Encrypted

AES-256 encryption at rest. Your knowledge stays yours. Export or delete anytime.

Obsidian-Native

Sync your vault directly. Your notes become AI context instantly. Bidirectional sync keeps everything current.

Open Source Core

Self-host free forever. The open source version is fully featured. No vendor lock-in, no restrictions.

Common questions.

Yes. AES-256 encryption at rest. You can export or delete all your data at any time. Self-hosted users have full control over their data.

Planned for v2. Version 1 focuses on Claude, ChatGPT, and Gemini via MCP and API integrations.

Yes, forever. The open source version is fully featured. The hosted version adds convenience, not features behind a paywall.

Memstalker is writeable. Your AI doesn’t just read — it updates its own memory after every session. It’s a living knowledge base, not a static retrieval system.

Platform memory is one model, one platform. Memstalker works across ALL models and persists YOUR knowledge, not just conversation history.
