I personally like the idea of not being private. The pureness of the internet, of sharing. I mean the names are anonymous as it is so just make another private account that you don’t give to your friends/family and go nuts. Now I do believe in mature ratings. I have turned on both my kids to Pearltrees so that’s a must. I mean I can totally understand wanting to have a storage place but there are tons of those on the net. This place is the perfect haven for ADHD personalities. ty

I love the way your embed works. Visitors can easily see the titles of each pearl, and then when they click on a pearl they can take a look at the site the pearl links to while still staying on your website.

I used it here and really like the way it works:

Hello,

I love Pearltrees. It’s allow me to organize all the links I collect on differents subject since I’m using internet.

Pearltrees does not let me add some of the links I have. Maybe the link is too long ? I hope I can add them pretty soon.

Great job guys,

I really like the design of Pearltrees. I’m a professor at a university where I teach blended and fully online courses. Because of copyright issues for materials included in my course materials, I need to restrict access to students in my classes.

Pearltrees seems easier to use than mind mapping software that I am currently using.

I would like to keep my Pearltrees private to protect copyright issues. I would share the link to a Pearltree diagram with students by through a link in Blackboard or web pages.

When will private accounts be available? Soon, I hope.

Jeff Closson, on April 13th, 2012 at 4:15 pm Said:

Pearltrees is PERFECT!!! At least I thought it was…. this is the exact user interface I’ve been looking for to sort out my personal and professional online life! The only problem is the LACK OF A PRIVATE OPTION. I’m fine with most of my links being public…. but in today’s world, there are MANY ways that I use the Web that I don’t want to share with others…. NO NOT THAT…. I know what you’re thinking, but I’m talking about financial transactions, medical information, legal matters, etc. etc. etc. I don’t want everyone/anyone on the Web to see even the SITES that I’m associated with because of the damage they could do to my identity, etc.

So, that would leave me with using PEARLTREES for stuff I don’t mind being public, and finding another solution for the private stuff. It defeats the purpose of having ONE place to organize my life if I have to have TWO places to do it.

Also, as a software developer myself, I am very skeptical of a site that has been promising for OVER A YEAR that the PRIVATE function is “a few months away”…. if you’re not going to do it, JUST SAY SO!

Thanks for the FALSE HOPE but I will be deleting my account now!
amsika, on April 19th, 2012 at 6:03 pm Said:

Hi Jeff,

We understand that people may need to organize some web pages privately, and that’s why we’ll implement the option to do so soon.
We’ve been postponing it for a few months because we have had a lot of projects and we couldn’t create everything at the samte time. For instance, we implemented the Team pearltrees, enabling people to organize their library collaboratively, then we released an awesome iPad app, and we’ll eventually release an iPhone app very soon so that you can have your library in your pocket 🙂
But be sure that we will implement the privacy option this year!
iant, on April 18th, 2012 at 11:56 am Said:

I love pearltrees!! I just discovered it a week ago or so and I’ve been hooked ever since. Such an innovative and useful concept. Can’t wait to see where pearltrees will be headed in the future. I can see allot of possibilities 😀 .Although I do like everything being public and being able to share my links with the world. It would definitely be nice to have the option to have a few private pearls.

Keep up the awesome work pearltree team!!

I can really appreciate what Pearltrees has to offer, but since I’d like to keep everything in one place I’m desperate for the option of making private pearltrees. I’ll be waiting to use the site when it happens, so I’m wondering what is meant by ” a few months” (from February)? Are you planning for the feature to become available in the next couple of months or, say, december?

Keep up the good work!

Hi,

I love pearltrees. But I try to search inside my pearltrees only but it can’t.

Exp: I search a key word “News” in my account, I have made in “News” pearltrees in my tree but there’s no result.

Can I rate or quote a pearl?

I wish that a pearl – which is the more picked the more glow. Then I can pay attention and visit that pearl as a recommendation.

I wish that the pearls in my collection will give me the update as RSS in the notification or in the color of the pearls or something is imaginable as star.

If the pearltrees can do that. It’s great!

GOOD JOB! Love your innovation. 🙂
amsika, on April 27th, 2012 at 5:12 pm Said:

Hi,
Thanks for your comment and your feedback, I take note of it!
Here are a few details :
The search engine may need a few days to index the new pearltrees. If you check out later it shoudl be ok 🙂 (we have greatly improve this with today’s new version)
You can rate a pearl, but you can pick it or comment it if you like it 🙂
Tamara, on May 1st, 2012 at 10:32 pm Said:

I am really enjoying Pearltrees for sharing information in a very simple, intuitive format with my colleagues. I hope that there is never a privacy feature as I think that would build walls and take away from the open sharing that is happening…I think that is the real beauty of this site. My opinion: If you want information kept private, it shouldn’t be in a Pearltree. Looking forward to the iPhone app. Keep up the good work!!

I love pearltrees, amazing idea. But I supplement it with workflowy.com b/c you can’t make certain parts of the tree private. I bet if you polled the community this would be very high on the list of desirable features. Please implement private pearltrees sooner rather than later!

also, thanks for this great service, it is an awesome organization tool and also discovery method for related interestes.
amsika, on May 30th, 2012 at 11:13 am Said:

Thanks Alex for your comment. Private pearltrees sure is one of the most desired featured in the community. And we’ll implement it soon, you’ll just have to be patient for a few months 🙂
Alex, on June 6th, 2012 at 1:09 am Said:

Thanks amsika, I’m sure it will be worth the wait! personally, I’d even consider paying for a private pearltrees service.

also, something I’ve noticed is that the Feedback option under the question mark defaults to launching the mail client for your OS. At a University computer it is often undefined and so does not work. Not sure where to post feedback, but I’ve had a problem where if I click on the pearltrees interface my browser’s (chrome) hotkeys stop functioning (like ctrl+t/n for new tab/window).

thanks! =)
amsika, on June 7th, 2012 at 8:22 pm Said:

Thanks for your comment !
If there is no default mail client, it may indeed create an issue, since the question mark is supposed to launch it.
As for Chrome, if the issue appears again, try closing it and re open it. If it still doesn’t work, feel free to send us a mail at participation@pearltrees.com to let us know.

J’aime bien l’idée du “tout est libre” mais certains arbres de perles devraient pouvoir être librement figés, même temporairement, pour ne pas perdre l’architecture que l’on choisit de montrer.
Il y aurait coexistence d’architectures libres (construites collectivement) et d’autres figées.
Simple suggestion, sans être spécialiste…
amsika, on June 28th, 2012 at 1:41 pm Said:

Bonjour,
Merci pour ta suggestion !
Normalement, les perles d’un pearltrees sont “figées”, tant que l’on ne choisit pas de les organiser différemment. En revanche, dans une équipe, chacun peut les réorganiser.
Ce qu’il peut se passer cependant, c’est que l’un de tes pearltrees ait été réorganisé récemment. Ceci a pu arriver parce qu’il y avait trop de perles liés à une même perle, ce qui le rendait très difficilement lisible sur de petits écrans. Nous avons mis en place quelques limites qui font qu’à partir de maintenant, ce type de réorganisation n’arrivera plus sur les pearltrees qui ont déjà été réorganisés. Désolé pour ce petit désagrément.
N’hésite pas à me contacter si tu veux plus d’explications.

Hi there,

I just received an email about premium pearltrees, glad to hear that private pearltrees are included with this premium service. After reading the list of benefits it seems like this is the only prominent feature of the premium service, will there be other benefits added in the future?

Private pearltrees for 4.99/month is a little more expensive than I expected and the email and link do not really detail the specifics of how the private pearltrees work. Will they be integrated into the regular pearltrees? Will their existence be hidden or simply inaccessible? Will there be a limit to the number of private nodes/trees? When you say no promotion or ads, does this mean you will be adding promotion and ads to the regular service? What happens when you stop paying the monthly/yearly premium fee, will your private pearltrees become public or be deleted?

A little clarification and more detail on the premium benefits and private pearltree logistics would be greatly appreciated. I’m hesitant to pull the trigger on the purchase until I fully understand what I will be receiving, but it is a great start!

Hi Alex,
Thanks for your interest in Pearltrees premium.
As you mentionned in your comment, we can’t reduce “privacy” to a feature, it’s like adding a new dimension to Pearltrees. It’s changing everything since you can choose precisely your level of privacy for each pearltrees or team.
Basically, premium member have the ability to create private pearltrees. They can put their existing pearltrees into a private pearltrees to transmit privacy. So you can choose exactly which of your pearltree will be private or stay public. There’s no limit of course!
It’s even more powerfull in teams! Now you can make a private team with your family to share personal photos, with colleagues to work on a sensible topic, with friends to prepare a suprise… Imagination is the limit.
With Pearltrees 1.0 we have created little tips to help people to use the product at its best. However some prefer to keep the interface quiet, that the real meaning of “no ads, ever!”. And when premium is expired, your private pearltrees remains accessible and private, you just wan’t organize them anymore.
Want more in premium? No worry, it’s a membership an some other premium features will be added soon. Background custimzation should be ready pretty soon. Keep posted!

Pearltrees premium really worth a try!
Keep pearling 😉
