The tool uses an unpacked Manifest V3 Chrome extension and a Native Messaging host to collect posts, then exposes them to Codex or Claude Code through a read-only MCP integration so assistants can retrieve source-linked evidence. The project is released as v0.2.0 on GitHub, with the developer noting the extension has not yet passed live account collection testing.", "body_md": "Likes and bookmarks on X and Threads are easy to accumulate and surprisingly hard to use. I save an implementation detail, a thoughtful comparison, or an idea for something to build. A week later, it is somewhere in an unsearchable pile. Meanwhile, Codex or Claude Code cannot use those saved posts as context unless I go find them and paste them in myself.\n\nI built **Social Memory** to connect those two disconnected habits: collecting useful posts and working with an AI assistant. It is a local-first evidence library for X/Twitter and Threads, not another feed to keep up with.\n\nA like does not mean the same thing to everyone. Sometimes it means “useful reference.” Sometimes it just means “thanks.” I do not want a tool deciding that every interaction belongs in my research library.\n\nSocial Memory lets you independently choose whether likes, saves/bookmarks, and reposts count as collection signals. You can collect bookmarks without likes, include reposts, or choose the combination that matches how you use each platform.\n\nThe storage model separates a post from the reasons it was collected. A post is stored once by platform and external post ID, even if several selected signals discover it. Capture metadata preserves why it entered the library. That distinction matters: I want to find one useful source, not three copies because I liked, bookmarked, and reposted it.\n\nThe workflow starts in the Chrome profile you already use. An unpacked Manifest V3 extension connects that profile to a local Native Messaging host. You do not export passwords or manually type profile IDs to make the connection.\n\nIf you use multiple Chrome profiles, load the same unpacked extension folder in each one and click **Connect**. Each profile receives a separate installation identity, while the local library deduplicates posts across profiles. Your work and personal browsing can contribute evidence without turning the same post into duplicate search results.\n\nFrom there, the intended loop is straightforward: choose collection signals, collect posts into the local library, search for relevant evidence, and let a connected assistant work with the results. I am deliberately describing the architecture here, not claiming the new extension has already passed live account collection testing. The preview limitations are below.\n\nSQLite and FTS5 provide local keyword search. I want the basic operation of finding a saved reference to stay understandable: a local database, searchable text, and links back to the original posts.\n\nThe read-only MCP integration gives Codex or Claude Code a way to retrieve source-linked evidence. The assistant can then group results, summarize them, and synthesize an answer. Social Memory supplies the evidence; the assistant does the interpretation.\n\nFor example, the kind of request I want to make is:\n\nFind the implementation notes I bookmarked last week, group them by approach, and link every source.\n\nFor a developer, that could turn scattered references into a comparison to investigate before coding. For a creator, it could help organize research without losing the original authors and context. In both cases, source links are essential. A confident summary is not a substitute for being able to check what someone actually said.\n\nThe [repository and README](https://github.com/ohmyjiro/social-memory) contain the setup instructions. The current release is [v0.2.0](https://github.com/ohmyjiro/social-memory/releases/tag/v0.2.0).\n\n```\ngit clone https://github.com/ohmyjiro/social-memory.git\ncd social-memory\nnpm install --ignore-scripts\nnpm install --global .\nexport SOCIAL_MEMORY_DATA_DIR=\"$HOME/.social-memory\"\nsocial-memory init --data-dir \"$SOCIAL_MEMORY_DATA_DIR\" --json\n```\n\nThat initializes the local side; it is not the entire setup. Follow the README for the extension connection and MCP configuration steps. I would rather keep those instructions in one maintained place than leave readers with a second, gradually outdated manual here.\n\nThe source of truth remains local. That does not mean every use of the library stays on your device. Content sent to a connected cloud AI may leave the device. Treat the assistant connection as a separate privacy decision, especially when deciding which collected material to include in a request.\n\nSocial Memory is **source-available under PolyForm Perimeter 1.0.1**. Review that license if you plan to build on it or distribute something derived from it.\n\nThis is a **development preview**, with real limits:\n\nIf you are a developer who lives in X/Threads bookmarks, try Social Memory and report where setup feels rough. I would especially value the exact step where the connection, collection, or retrieval flow stops making sense.", "url": "https://wpnews.pro/news/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory", "canonical_source": "https://dev.to/devjiro/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory-2amp", "published_at": "2026-09-14 05:09:15+00:00", "updated_at": "2026-09-14 05:26:26.905971+00:00", "lang": "en", "topics": ["ai-tools", "ai-agents", "developer-tools", "ai-products"], "entities": ["Social Memory", "X", "Threads", "Chrome", "Codex", "Claude Code", "SQLite", "GitHub"], "alternates": {"html": "https://wpnews.pro/news/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory", "markdown": "https://wpnews.pro/news/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory.md", "text": "https://wpnews.pro/news/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory.txt", "jsonld": "https://wpnews.pro/news/your-ai-cannot-use-the-posts-you-saved-so-i-built-social-memory.jsonld"}}
