"After eight years in the White House, Michelle and I now rejoin all of you as private citizens," Obama said in a video posted Friday morning to YouTube.
Michelle Obama told viewers it was time for the family to take a little break, finally removed from the Washington bubble after two terms.
"We won't be online as much as you are used to seeing us," the First Lady said.
It's been the honor of my life to serve you. You made me a better leader and a better man.— President Obama (@POTUS) January 20, 2017
I won't stop; I'll be right there with you as a citizen, inspired by your voices of truth and justice, good humor, and love.— President Obama (@POTUS) January 20, 2017
The Obamas also appealed for help as they transition to work on the new Obama Foundation, a center to be based on Chicago's south side.
It will be "more than a library and a museum," President Obama said, adding "it will be a living and working center for citizenship."
I'm still asking you to believe - not in my ability to bring about change, but in yours. I believe in change because I believe in you.— President Obama (@POTUS) January 20, 2017
The couple said they needed help, asking Americans to submit ideas about "your hopes, your beliefs about what we can achieve together."

Obama exited the presidency Friday with a message of gratitude to Americans and a plea to his supporters not to be bowed by the inauguration of President Trump.
"You proved the power of hope," Obama said before departing Washington as a newly minted ex-president.
In a farewell speech at Andrews Air Force Base before boarding the presidential plane for the last time, Obama said he'd been met by skepticism and doubt throughout his eight years in office by some who "didn't think we could pull it off." Obama said his supporters had transcended the obstacles posed by entrenched political powers by finding bonds of unity with Americans of all stripes.
He called that kind of fortitude "hope in the face of difficulty."
"Michelle and I, we've just been your front-men and women," Obama said. "It has always been about you, and all the amazing things that happened over these last 10 years are really just a testament to you."
Then Obama, a broad grin on his face, said goodbye to a crowd of 1,800 gathered to bid him farewell. He stopped to give hugs and handshakes to staffers and military members who had served his administration over two terms.
His last day in office started like any other: in the White House residence with his family. Yet by mid-morning, Obama and his wife were welcoming Trump and incoming first lady Melania Trump to the White House for a reception before accompanying them to the Capitol for Trump's swearing-in.
If Obama was feeling bitter about Trump's victory, he didn't show. He wrote a welcome note to Trump that he left in the Oval Office, and smiled as he stood alongside Trump at his swearing-in.
"This is just a little pit stop," Obama said minutes later at the air base. "This is not a period, this is a comma in the continuing story of being an American."
Trump, too, avoided any negativity about the man whose citizenship he once questioned.
"We are grateful to President Obama and first lady Michelle Obama for their gracious aid throughout this transition," Trump said in his inaugural address. "They have been magnificent."
Obama and his wife boarded a helicopter and flew to the air force base to speak to supporters in an airplane hangar. He and Mrs. Obama then walked a red carpet up to the steps of the presidential aircraft that ferried him on so many trips around the world. This time, though, it was designated a "special mission" instead of Air Force One, because the sitting president was not on board.
Obama and his family were to arrive later Friday in Palm Springs, California, where they'll have their first vacation as private citizens. The Obamas will return on an unspecified date to Washington. The family has rented a home where they plan to live until youngest daughter Sasha finishes high school.
There was one final throwback to Obama's celebrated campaign chant as he exited the national stage. It started as a shout from supporters as Obama arrived at a base, then was repeated by the president as he finished his speech.
"Yes we did," Obama said. "Yes we can."
