Ask HN: What is your go-to solution for a personal wiki in 2026?

For me the main requirements are:

* Backed up to cloud

* Has a mobile app that is easy to make small changes (for example if I'm doing an oil change on my car I need to be able to pull out my phone and log it in the wiki easily)

* Simple file format like markdown so that you're not locked into something proprietary (no need for crazy formatting options like MSWord)

* Option to export data out as a backup

* Allow uploading arbitrary files like PDFs, images, receipts etc...

* Nice to have: support for inline tables of data with simple calculations/sorting
