Trialware Submit (TSubmit) is a free Windows program that aids developers in submitting their trial software to software download sites. The program includes a browser window to allow site submission from within the program itself. Software authors can easily visit a software site's home, search, submit and update pages. TSubmit can used to keep track of sites submitted to, published and previously published.

The program includes all company and program information stored in a convenient tabbed dialog screen. An individual item can be copied to the clipboard merely by clicking on the desired item. After visting the submit page, authors submit their software to a site by pasting these items into the relevant form fields. The power-paste features allows quick pasting of common data items. In addition, many form fields can be automatically filled in at the touch of a keypress. Completed forms can be saved to improve the auto-fill process next time the site is visited. E-mail submission can be sent with the touch of a button.

TSubmit also allows authors to store their password and login ID for each site. The software contains a site update feature and has the capability to support multiple languages. TSubmit currently contains up to 340 software sites.
