What MefOrshei HaOtzar
users are saying

“I purchased Otzar HaHochma in order to buy and enjoy Mefarshei HaOtzar.
That sort of speaks for itself, doesn’t it?”
Rabbi Yehuda Stier
“An excellent idea.
Otzar HaHochma – 2nd generation”
Rabbi Uriel SchlangKovea Itim l’Torah, Bnei Brak
“What the heart desires, time conspires to do away with… It’s a fantastic idea! It saves me the time needed to open seforim as I go about preparing the shiur…”
Rabbi Yehoshua RabinowitzDaf Yomi Speaker, Yerushalayim
“I see exceptional Maggidei Shiurim and Kollel Avreichim go wild when they see this program.”
Rabbi Binyamin SegalMashgiach in Yeshivas Machnovka- Belz, Elad
“Yeshar Koach for this important initiative and for the great effort invested in its creation. It’s a brilliant idea.
I derive great benefit from using the program – the interface is convenient and extremely practical. The sections are perfectly divided, you get instant access to all kinds of meforshim – whether they’re comments on Ein Mishpat, or Masores Hashas – it saves loads of time that would have been used flipping through the books by hand.
You can gain an extensive command of the sugyas with the various approaches of the Meforshim, with minimal effort.”
Rabbi Eidan ChadadAvreich, Bet Shemesh
“This is a stunning project, that can be of use to so many different people. I, personally, enjoy it tremendously, both for its visual aspect – for the way it looks, and how it’s laid out – and for the incredible concentration of commentators that it brings you…
In my opinion, it’s worth considering adding more Marei Mekomos in Masores HaShas and Ein Mishpat, such as the Tur, Shulchan Aruch, etc.. In any event, though, it’s a phenomenal and blessed initiative. Clearly, a great deal of effort has gone into this!”
Rabbi Mordechai ZakenDelivers Shiurim in Shuls in Katamon Studies in the “Shaárei Nechama” Kollel, Yerushalayim
“Unique! It saves precious time, and gives you a solution that compromises between searching independently in the source references – which has the advantage of making you toil, and allows for accuracy, binding the learner to the sugya – and between learning from Melaktim, which has the advantage of speed, and enables you to cover more ground. Moreover, I made some precious discoveries and found gems that I would probably not have found any other way!”
Rabbi Boruch Mordechai KampehKollel Avreich in Zichron Kelm, Bnei Brak Author of the Darkei Baruch Books
“I am in the middle of writing a chaburah on Shabbos Daf 80. I clicked onto Mefarshei HaOtzar, and – Wow! What a treasure chest full of precious discoveries! It’s priceless! You’ve made me very happy!!!”
Rabbi David SoferRosh Yeshivas “Kaf HaChaim”, and Rav of Kehillas HaSefardim / Givat Zeév HaChadasha
“I’ve been introduced to the beta version of Meforshei HaOtzar. I’m speechless… this is a masterpiece that surpasses any innovation that we may have imagined you may come up with. I’m waiting impatiently to update the program and bring the “Otzar” into my home."
Rabbi Noam Lesser a veteran program user, and Meishiv in the Mir
“You’re taking away our excuses for Judgement Day! Everything is so convenient and accessible; pleasing and engaging… Every few lines of Tosfos reveal to the learner whole new worlds of chiddushim that were written throughout centuries. It’s amazing!”
Rabbi Eliyahu FischerRosh Mesivta in Yeshiva L’Tzeirim, an editor of Torah works, and one of Otzar HaHochma’s earliest users
"I wanted to thank you for opening the Otzar to the general public, As a Maggid Shiur I wanted to tell you that 'Meforshei HaOtzar' is a wonderful resource, "עוד לא בא כבושם הזה" On these crazy days, I'm preparing my Shiurim at home and giving them over the phone, and the Meforshei HaOtzar has been a great facilitator in making this run smoothly for me. With sincere gratitude"
Rabbi Yehoshua DavidowitzAshdod
What’s more, it’s been a long time since any works have been published on Gemara, Rashi & Tosfos. Some of the most recent ones were Ayelet HaShachar and Minchas Yehuda. But in light of this initiative, I think it’s worth going back and writing brief comments on Gemara, Rashi & Tosfos that will be widely used…”
Rabbi Avraham Moshe RothRosh Kollel Achvas Torah, Jslm. and one of the Rabbonim of Kehillas Rosh HaGivah / Givat Hamivtar
"In our Beis Midrash on Bublik Street in Ramot, We have a stand with the Otzar Hachochma program for public use. First, we wanted to express our gratitude to the Otzar Hachochma team for the wonderful software that has changed the face of the Torah world. Recently, we've added the new Meforshei HaOtzar software, 'וכל הרואה אומר ברקאי' There are no words to describe the tremendous benefits to the Beit Midrash and the Kollel from this new software. יישר כח, ויה"ר שיהא חלקכם עם מזכי הרבים לעולם."
Minian Avrechim ShulRamot, Jerusalem
"I have no words to describe it - it's simply INCREDIBLE!! I'm going to be so addicted to it, I'm afraid I'll never want to use a regular Gemara again! What's going to be on Shabbos?"​
Rabbi Shmuel Sterinhardt​Yeshiva Yesodei Hatorah, Toronto
Thank you, we are still locked up here, the Meforshei Ha'otzer is wonderful. I must say, I am really so impressed with how well it is made. If I wanted to, I could not think of a better way to do it - the way the text is highlighted under the mouse hover, and how the meforshim are grouped and the specific, relevant part on the page is shown - it's amazing
