Periodic Notes Synthesizer
Synthesize your daily notes into themes, loops, follow-ups
You keep daily notes but rarely read back across them. Periodic Notes Synthesizer reads all of them and writes one synthesis: recurring themes (where notes agree and contradict), a this-week rollup, open loops with a stale flag, and a said-vs-did check on your old commitments. Bring your own API key. No server, no account, no subscription. Free tier plus a one-time Pro license.
I keep daily notes in Obsidian, and after a few months I had a folder full of them that I never reopened. The capture was happening but the reading-back never did.
So I built something that reads across all of them and tells me what kept coming up, what I said I would do versus what I actually did, and which loops were still open weeks later.
I have no coding background, so I built this entire plugin with Claude writing the TypeScript, designing the architecture, and walking me through every step. It is my 5th Obsidian plugin.
One honest note on privacy: it is bring-your-own-key, so your notes do go to whatever LLM provider you pick. What I can promise is there is no server and no account on my side. Nothing routes through me.
