Upcoming: TeX Writer as a Web App
It's time to bring TeX Writer to browser, so that users can edit their documents even without their tablets around. It will be free for editing only. If you want to compile it online, we'll provide paid online compilation (monthly/annually subscription). All files are still saved in your Dropbox folder.We won't save a copy of your files on our server. For compilation purpose, the server will download necessary files. These files will be deleted after a short period (no more than a few hours). If everything goes well, the launch time will be early January 2014. Please let us know if you are interested. We may be able to offer limited time PRO accounts (with online compiler, online pdf review) for early users.
Update: web app is available now! https://texwriter.net
