SellLightは、フリマ出品の文面づくりを軽くする出品準備アプリです。 商品名またはURLを入力すると、商品の特徴候補を作成。伝えたい特徴を選ぶだけで、タイトル案、説明文、タグ、確認事項をまとめて生成できます。 「説明文を考えるのが面倒」 「商品の魅力を短く伝えたい」 「出品文を毎回ゼロから書くのが大変」 そんなときに、SellLightが出品前の作業をサポートします。 主な機能: ・商品名またはURLから出品準備を開始 ・商品特徴候補を自動生成 ・選んだ特徴を本文へ反映 ・タイトル案、説明文、タグを作成 ・説明文を編集してからコピーできる ・画像候補の確認と保存導線 ・iPhone、iPad、Macで使いやすいUI SellLightは、AIにすべて任せるのではなく、AIが候補を出し、ユーザーが選ぶ流れを大切にしています。 選んだ特徴をもとに文面を整えるため、自分の意図に近い出品文を作りやすくなります。 商品状態、付属品、傷や汚れ、発送条件などは、必ず実物を確認したうえで出品してください。 SellLightは出品文作成を補助するツールであり、出品内容の最終確認はユーザー自身で行う必要があります。 利用規約(EULA):Apple標準使用許諾契約 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ プライバシーポリシー https://tenten-10-10.github.io/selllight-lp/#privacy
