Borland Sidekick was a personal information manager (PIM) that Borland launched in 1984 under Philippe Kahn's leadership. It was an early and popular terminate and stay resident program (TSR) for DOS operating systems, which enabled computer users to activate the program using a hot key combination (by default:Ctrl-Alt) while working in other programs. Although a text mode program, Sidekick's window-based interface echoed that of the Apple Macintosh and anticipated the eventual look of Microsoft Windows 2.0. It included a personal calendar, text editor (with WordStar-like command interface), calculator, ASCII chart, address book, and phone dialer. According to the prospectus for Borland's initial public offering of stock to the public, Sidekick sold more than 1 million copies in its first three years.

According to Philippe Kahn, Borland did not originally intend to sell Sidekick. It developed the utility to assist the small company's employees. After several months of use Borland realized that it had a saleable product.
Sidekick 1.0 included Calculator, Notepad, Appointment Calendar, Auto Dialer, ASCII Table and other tools.
Sidekick 1.0 Plus included a broader selection of calculators (Business, Scientific, Programmer, Formula), a 9-file Notepad text editor, Appointment Book and Scheduler, a terminal communication tool and ASCII Table. In addition to variants on and enhancements to the 1.0 features, Plus included a 9-file Outliner, q file and directory manager, Clipboard, and supported Expanded Memory and a RAM disk.

Sidekick 2.0 was the last DOS version.
When Philippe Kahn left Borland in 1994 to found Starfish Software, he acquired all rights to Sidekick from Borland. Starfish's co-founder Sonia Lee Kahn designed the look and feel of Sidekick 95, which was launched simultaneously with Windows 95 with great success. In 1998 Philippe Kahn and Sonia Lee Kahn sold Starfish to Motorola for $325 Million in a private transaction. Software and trademark were sold to become a division of Motorola. Starfish was later bought by Nokia who discontinued the product, with Sidekick 99 being the last version. T-Mobile USA, Inc. currently owns the Sidekick trademark portfolio.
Later versions of the program were made available for Windows, with the last versions featuring a phone dialer and syncing with Palm, Windows CE, and EPOC devices. These versions were less popular than the DOS versions, largely because the Windows environment itself provided most of the original version's key features: task switching and a collection of small utilities. It did however, include a monthly/yearly calendar and a world time map showing which parts of the world are currently in daylight or darkness. Up to eight different world cities (which could be edited) were displayed above and below the map.
Sidekick for Windows 1.0 was developed and released by Borland before Kahn left the company. It was designed for Windows 3.1 and included Calendar, To Do List, Contacts, a communication tool and a calculator. However, most of the design and file system came from the YourWay PIM software, purchased by Borland from Prisma Software in 1993. As the November 7, 1994 Info World noted, "Despite its name, the only connection between Sidekick for Windows 1.0 and the venerable Sidekick for DOS is that Borland International owns both programs. Sidekick for Windows is a combination of the calendaring code from Prisma Software Corp.'s Windows PIM YourWay (purchased by Borland last year) and a completely new interface developed by Borland." 
Sidekick 2.0 was also developed and initially released by Borland before the move to Starfish.
New/modified features included:
- overlapping appointments in the Scheduler,
- multiple contact files in the Address Book,
- print layouts that enabled users to print to commercial day planner pages,
- Backup & Restore of user's files,
- password protection.

Borland sold 400,000 copies of Sidekick by September 1985. InfoWorld stated in November 1984 that "whoever wrote this gem understands Murphy's law ... Sidekick stands in the shadows behind whatever program you are using", and noted that for programmers, the software was less expensive "and a lot handier" than a Texas Instruments hexadecimal calculator. The magazine concluded that "Sidekick is a time-saving, frustrating-saving bargain [and] is the first step to making paper and pencil obsolete." Jerry Pournelle praised Sidekick in Byte in October 1984: "Philippe Kahn ... now has a product that IBM PC users won't be able to do without. He ought to sell a zillion copies". Elsewhere in the issue, the magazine stated that Sidekick's existence "seems to point out a major drawback in quite a few integrated software packages. Why should owners of advanced, multifunction business programs that are supposedly easy to use and that claim to solve all problems be compelled to purchase a utility like Sidekick? It makes you wonder about all those advertising claims". In January 1985 Pournelle selected Sidekick as one of his products of the year for the IBM PC. BYTE in 1989 listed SideKick Plus as among the "Distinction" winners of the BYTE Awards, stating "Talk about a bang for the buck".
