Engram Blog
How we build Engram, what we've learned, and what we'd do differently. Mostly technical, occasionally opinionated.

When Claude Code compacts, it replaces your conversation with a lossy summary — and the agent trusts it, confidently rebuilding decisions it half-remembers wrong. Here's how to recover the exact words, and the CLAUDE.md rule that makes it automatic.

A full ChatGPT conversation can't call tools anymore — so it can't save to Engram either. The escape hatch: grab the share link and run one CLI command. Every word rescued, searchable forever.

Engram Vault mirrors your AI memories into Obsidian as real markdown notes — synced, tagged, graphable, searchable. Built by a customer on our public API, no permission needed. And his one feature request shipped: the update API is live.
· 6 min read · vault, security, secrets, cli, how-it-works
Engram's secrets vault is zero-knowledge: keys are generated on your machine, values are AES-256-GCM encrypted before upload, and the server only ever stores ciphertext. How it works, and exactly which surfaces get it.
· 6 min read · claude-code, tokens, context-window, mcp, how-to
A long Claude Code session re-reads 100k+ stale tokens on every turn. Retrieving the same context from Engram costs about 2,000 — we measured it. Here's the math and the save → /clear → recall workflow.
· 5 min read · import, chatgpt, how-it-works, deduplication
Afraid re-importing your ChatGPT export will double everything? Engram deduplicates by conversation — re-upload as often as you like, and only genuinely new conversations get added. Here's exactly how it works, honestly.
· 8 min read · memory, codex, claude-code, verbatim, comparison
ChatGPT, Claude, and Codex all ship "memory" now — but every one of them stores a compressed summary, not your actual words. Here's the evidence from Codex's own database, why they all work this way, and what verbatim memory looks like instead.

Your ChatGPT conversations are locked in one app. Here's how to export your full history, back it up permanently, and make every conversation searchable from ChatGPT, Claude, Cursor, and any AI you use.
· 7 min read · chatgpt, cross-platform, mcp, tutorial
Connect Engram to ChatGPT in 30 seconds. Then connect it to Claude Code, Cursor, or any MCP client. Research in one tool, execute in another — same memory, zero copy-paste.
· 8 min read · team, agents, shared-memory, architecture
A seat on Engram's Team plan doesn't have to be a person. It can be a deploy bot, a support agent, a code reviewer — any AI agent that needs shared context with the rest of your team.

Claude Code resets its context every session. Here's how to add cross-session memory using Engram and the Model Context Protocol, so your agent remembers past decisions, investigations, and context.
· 8 min read · comparison, memory, mcp
A fair comparison of three agent memory servers — Mem0, Zep, and Engram — covering storage models, protocols, search, pricing, and when to pick each.
· 6 min read · cursor, mcp, tutorial
Cursor resets context every session. With one MCP config block, you can give it memory that persists across sessions, projects, and machines — using Engram.

Why we picked D1 + Vectorize + Workers AI over the obvious stacks for Engram, what the latency math looks like, and where the edges of each service actually are.
