Community Directory: Emotional Time Capsule


I write plugins that synthesize other people’s backlogs — reading lists, meeting notes, that kind of thing. This one’s different. It doesn’t synthesize anything. You write a note, seal it, and it sits there until a date you picked, then shows up again asking you to look at it with whatever perspective you have by then.

The idea came from noticing how differently the same piece of writing reads a few months later. An angry email you didn’t send. A “what am I even doing” journal entry from a bad week. Read right after writing, it’s just raw. Read six months later, it’s information about who you were.

What it does:

  • Unsent letters, messages to a future self, difficult-day reflections, decision records, gratitude notes, milestones — each with its own writing prompts
  • Seal a note and it shows a plain placeholder (title, dates, a short message) instead of the contents until the date arrives, with an “open early” option if you don’t want to wait
  • A dashboard that sorts everything into Ready to revisit, Sealed, Unsealed, No revisit date, Archived
  • Postpone, archive, delete — normal file operations, nothing locked away for real

Worth saying plainly: sealing is not encryption. It’s a calm UI choice, not a security feature. The note is still a normal Markdown file and you can open it from outside the plugin any time. I say this directly in the plugin and the README because I don’t want anyone assuming more privacy than it actually gives.

Everything above is free, no cap. The one paid thing is search/filter/sort on the dashboard, $2.99 one-time — I figured once you’ve got enough capsules that finding one is actually a problem, that’s a fair moment to ask for money, and not before.

One more thing, since it’s relevant to why I priced it the way I did: all the money from this one goes to feeding a stray cat colony near my building in Istanbul, plus my own cat and two rabbits. This plugin started as something I wanted to build for its own sake, not as a business, and I’d rather it stay that way.

Your plugin sounds very interesting, however…

In your post, you indicate that the plugin has been vibe-coded beyond your ability to comprehend how it works.

As the author, how will you support it if we run into issues using it?

You know, through the vibe-coding, beyond the author’s ability to comprehend how it works… I guess.

Cheers, Marko :nerd_face:

Fair question. A few things that make this lower-risk than it might sound:

  • The plugin is open source, so if I disappear the code doesn’t. Anyone can fork it or fix it.
  • It doesn’t touch anything destructive by default — capsules are plain Markdown files in your own vault, and “sealing” isn’t encryption, so nothing is ever locked away if something breaks. Worst case you’re looking at a normal .md file.
  • No server, no account, no external dependency that can go down and take your data with it.

In practice, support means: I read GitHub issues and respond, and Claude Code writes the actual fixes based on what I ask for — I don’t personally read every line, but I do test everything in Obsidian before shipping, and I’ve been keeping up with issues on my other 7 plugins the same way. If something’s broken, open an issue and I’ll get to it.
