Get 20% Off for Personal Knowbase’s 20th

Happy 20th Anniversary, Personal Knowbase!

Personal Knowbase 1.0 was released May 4, 1998. We’re celebrating its 20th anniversary with a limited-time 20% discount.


We first uploaded PK 1.0 to CompuServe’s Windows software forum 20 years ago. It’s come a long way since then. See our previous blog post for more information about The History of Personal Knowbase.

For one week only, from May 4 to May 10, we are offering 20% off all orders of Personal Knowbase from our web site. This rolls back the price to the original 1998 price of $39.95.

Pass it on!

Please tell your friends and colleagues about it. Help them take control of their notes!

To get the discount, just order from our primary software order link on our order page. The discount is applied automatically.

    Congratulations on the 20th anniversary for PersonalKnowbase. I’m not sure when I bought my first copy; probably around 2000. And I still have the latest version on my Windows PC at work. It’s nice to see a good piece of software having some staying power. I’ll be sure to comment on your 40th anniversary.
