What Twiddla is
Twiddla is an online whiteboard for collaborating on web pages, uploaded images, documents, or a blank canvas in real time. Participants can browse a website together, annotate it, share files, and discuss the session by chat or voice. Users can start a whiteboard for free without signing up, and invitees do not need accounts. Sessions can be captured as images, embedded as widgets, or reloaded in Twiddla for more editing. Its API can create meetings and embed them in another site with an iframe; it also supports hiding interface elements and custom branding on eligible plans. Client libraries are documented for .NET, PHP, Python, and Java. Guest meetings allow up to 10 participants and run for no more than 20 minutes; guest voice conferencing is disabled. Twiddla is not a screen-sharing or video-chat service, does not work with Flash websites, and is not intended for editing documents or spreadsheets. The Pro plan costs $14 a month. The maker identifies Expat Software as the company maintaining Twiddla.
