New Intent API

20 Feb 2015 api, intent

If you have been using, you may have wanted to create or update intents programmatically (i.e. without logging in to the Wit Console).

One frequent request we have been hearing from the community is to add expressions programmatically to an existing intent. This would be helpful if you already have a corpus of synonymous expressions that you want to load into an intent to save you the time of typing each and every expression into the Console.

You can now use the HTTP Intent API to not only create or update an intent but also add or remove expressions from existing ones.

Here is an example of Intent creation via the API:

 curl -XPOST '' \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"name":"greetings_mood",
       "doc":"detect questions about mood",
          "body" : "how are you?"
        }, {
          "body" : "what\u0027s up"
          "body" : "how are you doing"

Note that it is currently not possible to tag entities while submitting expressions via the API. We will add this in the future.

Please contact us if you have any questions.

Why we're quitting Stripe

08 Jan 2015 news

Are you surprised by the title of this post? Of course you are, everybody loves Stripe and we are no exception. Stripe continues to set the standard in terms of developer-friendly API. And BTW, big thanks to John Collison for supporting us since our start !

We are quitting Stripe because is now free for all developers. This is a consequence of joining Facebook.

You can now create private instances or make open instances private for free. Go to the Settings tab of your instance to change it from private to open or vice versa.

So if private instances are free, why would you bother to create open instances? We believe that like open source code, open instances will benefit from the community: as other developers fork and improve your instance, future features will give you an opportunity to merge improvements back to your original instance. We are actively working on this, so stay tuned!

The most interesting journeys involve unexpected surprises.

For a long time I’ve been obsessed with building machines that understand human languages. 18 months ago, we started with the vision that no solution is to be found in a closed, centralized, managed approach. We’ve been building an open, distributed, community-based platform that makes it easy for developers to build apps that users can talk to.

A great community of 6000+ developers joined forces on the platform, and is already powering hundreds of apps and devices. We gathered an incredible group at our LISTEN conference in November. But we are just scratching the surface of the problem.

That is where today’s big news comes in: is joining Facebook!

It is an incredible acceleration in the execution of our vision. Facebook has the resources and talent to help us take the next step. Facebook’s mission is to connect everyone and build amazing experiences for the over 1.3 billion people on the platform – technology that understands natural language is a big part of that, and we think we can help.

The platform will remain open and become entirely free for everyone. Developers are the life of our project and the energy, enthusiasm and passion of the community has helped turn what was once just a lofty dream, into a reality. We want to continue to build with you.

We wouldn’t be where we are without the developers, investors, and mentors who believed in us. We want to thank everyone who has been a part of the first leg of this journey. This is just the beginning.

Talking to Muppets, Challenges of Voice Interfaces for Kids by Oren Jacob

22 Dec 2014 conference, community

We hosted the LISTEN conference in San Francisco last month (full recap here).

Following last week’s videos of The Story of Siri, by its founder Adam Cheyer and The Language of Food (and Dating), by Dan Jurafsky we are happy to release today another great keynote: Talking to Muppets, Challenges of Voice Interfaces for Kids by Oren Jacob.

Oren is the CEO of ToyTalk and was the former CTO at Pixar.

Oren took the stage with a hilarious presentation on developing voice interfaces for children. He shared clips of children talking to the ToyTalk apps and anecdotes of his research with children to demonstrate the challenges of designing voice applications for kids. He also touched on the regulatory issues surrounding recording children and how ToyTalk approaches these challenges.

Thanks again to Oren for this insightful presentation.

The Language of Food (and Dating), by Dan Jurafsky

19 Dec 2014 conference, community

Last month we hosted the LISTEN conference in San Francisco (full recap here).

Following yesterday’s video of the story of Siri, by its founder Adam Cheyer, we are pleased to release today another great keynote: The Language of Food by Dan Jurafsky.

Dan did a captivating talk on the Language of Food. He opened the talk with the history of ketchup and how the language of food can expose historical revisionism. He then moved on to his research on food marketing and potato chips, sharing that every negative word on a potato chip bag add 4 cents to the cost. Dan wrapped it up with a look at the language of menus and speed dating.

Thanks again to Dan for this treat!
