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, mark it up, share files, and discuss the session through chat or voice. A whiteboard can be started for free without signing up, and invitees do not need accounts. Sessions can be captured as images, embedded as widgets or reopened in Twiddla for more editing. Its API can create meetings and embed them in another website with an iframe; client libraries are documented for .NET, PHP, Python and Java. Paid subscriptions list SSL security and password-protected private meetings. The free Guest option allows up to 10 participants for 20 minutes and has no voice conferencing. The Pro plan costs $14 a month. 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. Expat Software maintains the service.
