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

Question

I've used Notion for a long time but I'm interested to hear what other alternatives exist 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, etc...* Nice to have but not essential: support for tables of data with simple calculations (e.g. sum this column)

The Fossil SCM () meets most of your requirements, noting that:- "mobile app" means "its web interface"- "backed up" means to wherever you upload/sync your backups to- No automagic table calculation support.
