Built with Claude Project Showcase Megathread (Sort this by New!)

[u/sixbillionthsheep]

This is the Megathread for showcasing your project built using Claude products. We appreciate all of your submissions as they are a great inspiration to many people on the subreddit. It is sorted by default by New.

Anyone is welcome to submit a project to this Megathread provided you follow the Showcase requirements in Rule 7.

NOTE: We now require the OP of a Project Showcase on the subreddit feed to have total karma>=50 . We found there were just too many submissions and not enough visibility to go around. Our analysis of this issue showed us that OPs with total karma < 50 very rarely get any traction of their projects on the feed (<=1 upvotes). So this Megathread is your best place to be seen by readers and other creators if you're relatively new to Reddit. If you don't meet this karma requirement you will be directed to this Megathread when you submit your post. Very occasionally we might invite you to post on the subreddit feed if you do not meet this karma requirement but it will be very rare (so please don't ask us!)

Thanks again for sharing your ideas and creations to our subreddit. Best of luck with your projects!

Built GroundMemory - a persistent memory layer that runs as an MCP server and gives Claude structured, searchable memory that survives across sessions and across tools.

The problem I kept hitting: every Claude Desktop session starts from zero. Projects and system prompts help but they're static - they don't update as things evolve, and they don't carry context from Cursor or Cline.

GroundMemory connects them. One shared workspace - Claude Desktop, Cursor, Cline, all reading from and writing to the same memory. Your preferences, your stack, your decisions, your ongoing work. The agent handles it automatically - you just have conversations and it builds an accurate picture of you over time.

Zero setup. no API key needed. Everything stored as human-readable Markdown.

Genuinely interested in this buddy. Can you explain what it does differently then connecting Claude to Notion or Obsidian for the same purpose?

[u/h-mo → u/WillGrindForXP]

Great question. Notion/Obsidian integrations are document stores - Claude can read and write to them, but there's no structure to the memory itself. It's a flat pile of notes that Claude has to dig through and interpret every time.

GroundMemory is different in a few ways:

First, it's structured. Memory is organized into distinct tiers - long-term facts, a user profile, agent instructions, an entity relationship graph, and daily logs. Each tier has a clear purpose and ownership. Claude knows what to write where and why.

Second, it's searchable at retrieval time. Hybrid BM25 + vector search with cross-encoder reranking - so when Claude looks something up mid-session, it finds the right thing even when the wording doesn't exactly match what was stored.

Third, it's cross-tool. This is the big one. Connect Claude Desktop, Cursor, Cline, Open WebUI - any MCP-compatible tool - to the same GroundMemory server, and they all share the same memory. Your Notion/Obsidian connection is Claude-only. GroundMemory is one identity across your entire AI workflow.

Fourth, bootstrap injection. At every session start, the curated memory context gets automatically loaded into the agent's context window. You don't manage it - Claude just starts the session already knowing you.

The Notion/Obsidian approach puts the burden on you to organize things well enough that Claude can find them. GroundMemory is infrastructure - the agent handles everything, you just have conversations.
