Clannad is a drama and romance visual novel in which the player assumes the role of Tomoya Okazaki. Much of its gameplay is spent on reading the story's narrative and dialogue. Clannad follows a branching plot line with multiple paths and endings. There are six main plotlines that the player can experience, five which are initially available. At various points during gameplay, the player is given a dialog choice that can influence the progression of the story. When first playing the game, the scenarios for all five heroines and additional smaller scenarios are available in what is called the School Life story arc. When the player completes a character's scenario, he or she receives an orb of light. When eight of these lights are obtained, the game's second story arc, called After Story, is made available. One of the lights disappears during School Life, but reappears in After Story. To view the true ending of Clannad, all 13 lights must be obtained. Originally, the lights were meant to be items that players could use in the game, but since this increased the game's complexity, and detracted from the storyline, the function of the lights was simplified and made less intrusive.

Clannad takes place primarily at the fictional Hikarizaka Private High School in Japan. Outside the school, the most common locations include the bakery run by Nagisa's parents and dormitory where Youhei Sunohara lives. Throughout the series, glimpses into an Illusionary World are shown. There are recurring themes that appear throughout the series. The main theme is the value of having a family, as the title of the series implies because the main scenario writer Jun Maeda mistakenly thought the name of the Irish band Clannad meant "clan" or "family" in Irish, which is just "clann". Of the six main characters, Tomoya, Nagisa, and Kotomi do not have siblings, but their parents are major factors in their stories. Nagisa's story was written to incorporate what Maeda described as a "perfect family" with a focus on mental consciousness. In Nagisa's story, there is a recurring appearance of "The Big Dango Family" (だんご大家族, Dango Daikazoku) (a fictional group mascot for children) that Nagisa is fond of. Tomoya and Nagisa's characters were written in a style to exemplify a "growth to adulthood" by the end of the story. Fuko and Kyou's stories have their sisters playing an integral part, while Tomoyo's is influenced by her entire family. A minor motif of Irish words continues with the opening theme of the game, "Mag Mell", which means roughly "plain of joy" and is connected with Irish mythology. The arrange album, a short music CD that contained remixed versions of songs in the game, that was bundled with the original game release was titled Mabinogi, which was a collection of prose stories from medieval Welsh manuscript.

Clannad revolves Tomoya Okazaki, a third year high school student who dislikes his life. Tomoya's mother (Atsuko) died when Tomoya was young, leaving his father (Naoyuki) to raise him. After the accident, Tomoya's father turned to alcohol and gambling, with frequent fights with his son. One day, Naoyuki slammed Tomoya against the window in a family argument. dislocating Tomoya's shoulder. This injury prevents Tomoya from playing on the basketball team, and causes him to distance himself from others. Since then, the two men to be estranged with each other. At the beginning of the school year, Tomoya meets Nagisa Furukawa, a strange girl who is one year older than he is and repeating her last year in high school due to being sick much of the previous year. She aims to join the drama club, but cannot do so due to her sickness. However, they find that the drama club was disbanded after a few remaining members graduated. Tomoya helps Nagisa to reform the drama club before meeting several other girls whom he gets to know well and help with their individual problems. In After Story, Tomoya and Nagisa get married and start to live together. Just after Nagisa gives birth to their daughter, Ushio, she dies, which causes Tomoya to become depressed. As a result, Nagisa's parents – Akio and Sanae – take care of their granddaughter. Five years later, Tomoya meets with Shino Okazaki, his paternal grandmother. Shino tells Tomoya about his father's traumatic past, after which he resolves to raise Ushio and recognizes Naoyuki as his father. Shortly after Tomoya overcomes his depression, Ushio suffers the same disease that Nagisa had. Tomoya, Sanae, and Akio struggle to save him but all of their efforts turn out terribly.

The executive producer for Clannad was Takahiro Baba from Visual Arts, the publishing company which controls Key. Jun Maeda, who was one of three main scenario writers with Kai, and Yūichi Suzumoto, led the planning for Clannad and wrote the majority of the scenarios. Scenario assistance was provided by Tōya Okano. Itaru Hinoue headed the art direction, and also worked on the character design. Miracle Mikipon, Mochisuke, Na-Ga, and Shinory supplemented the computer graphics. Torino provided the background art. The game's music was composed by Maeda, Shinji Orito, and Magome Togoshi. For Key's second visual novel Air, Maeda admitted he felt he was able to write what he wanted to for the game's scenario, but he later discovered that Air was difficult for players to receive and experience. Due to this, Maeda felt that for Key's next work Clannad, he had a sense of duty to make the game easier to receive for as many users as possible. In any case, he wanted to make it an entertaining game, and started planning on Clannad almost immediately after Airs completion. From the start of Clannads planning, Maeda did not want to write a story like in Air, but instead wanted to focus on writing a deep connection between the 'people and the town', and 'humanity'. Maeda noted that he exceeded his writing ability when writing most of the scenarios in Clannad, and equates Clannads writing process as a "wall that I will never be able to get over again." While at the beginning Maeda felt he was prepared, the entire game's story started to increase to a level Maeda never predicted, and Suzumoto noted that it approximately doubled in size from the original projected length. Suzumoto attributed the increase due to the lengthening structure of the game's base scenario which caused the 'branch' scenarios to increase as well. There were more concerns about Clannad being similar to Air. When Nagisa's scenario was being written, there were some disputes concerning the length of her scenario, and thus putting too much focus on the main heroine. Some were concerned that having a single prominent character with a unique storyline would be too much like how Air was structured with the overall focus on Misuzu Kamio. Takahiro Baba, the company president of VisualArt's, is even noted as suggesting to minimize the differences between the other characters' scenarios, but this was ultimately ignored since Maeda thought the game's evaluation by players would not decrease on account of the scenarios being vastly different, and thought the result was a good one. Maeda was concerned that the After Story arc, mainly a continuation of Nagisa's scenario, would eclipse the entire game's scenario, much like what happened with Air according to Maeda. In order to prevent the same thing happening in Clannad, Maeda focused on making the first half of the story, the School Life arc, just as enjoyable by making it long and heart-breaking. Clannad is Key's second longest work, as reported by Yūto Tonokawa where he stated that Clannad is about 4,000 words fewer than Key's 2008 game Little Busters! Ecstasy.

For the anime television adaptation, the first season of Clannad received reviews ranging from positive to mixed, while the second season Clannad After Story received wide critical acclaim. The THEM Anime Reviews website gave the entire series a score of 4 out of 5 stars, with reviewer Tim Jones describing the first season as "the most fleshed-out and real Key animated adaption to date," and reviewer Stig Høgset stating that the second season After Story "will play up the tragedies and the drama considerably, quite possibly tearing out your heart in the process. This is where time truly starts to fly by, lending the show some real weight in the emotional departments." Theron Martin of Anime News Network gave the first season a 'B+' rating, criticizing its extensive use of moe elements, but considered it appealing entertainment for a "fan base who revels in this kind of thing." His review for the second season After Story was much more positive, giving it an 'A−' rating. He praised the second half of the season as "the best-written quarter of Clannad," stating that it "effectively builds up and delivers its emotional appeal, reinforces the series' central theme (i.e. the importance of family), and peaks visually," and concluding that "only the most cynical of souls will avoid shedding at least a few tears at certain points." On the DVD Talk website, the reviewer Todd Douglass Jr. gave Clannad After Story a "Highly Recommended" rating, stating that "the range of emotions Clannad takes you through is quite daunting. It's charming, cute, hilarious, mysterious, and tragic all at the same time. Few shows are as memorable, and few are this good for this long." He concludes that the storytelling is "heartfelt" and "memorable in so many ways," and that "few shows rise to the levels this one does."
