どちらを使うべきか？
you want to design one character step by step (niche, look, outfit, personality, voice), lock its face in a reference sheet, and generate its photos, image-to-video, talking clips, and video swaps in one workspace
you want a recurring world around your influencer (a home, friends, and pets), a free plan with a welcome credit bonus, low-priced plans, and credits that roll over and never expire
各プラットフォームが強い点
Synthetic describes itself with the line "Create worlds, not just AI influencers." Its homepage lists Living Spaces, Social Circles, Companions, World Context, AI Influencer Profiles, and Saved Presets, so a character comes with a familiar home, friends, and pets. Its pricing page lists a free Hobbyist plan and three paid plans, Creator, Pro, and Studio, plus credit packs. RYLA starts from the character itself: you design a new face in the builder, without uploading photos of anyone, and generate new content from that one character. Facts about Synthetic come from its public homepage and pricing page, as of 15 October 2026. RYLA plans come from the RYLA pricing page. The table includes the rows where Synthetic is ahead.

同じ顔、4つの異なるシーン
ここにある画像はすべて RYLA で生成しました。ひとりのキャラクターを4つの異なるシーンに置き、その間に修正は加えていません。
RYLA が勝つ点
自分の写真は不要
RYLA のビルダーは、アップロードされた写真からではなく、あなたがデザインするキャラクターから始まります。ニッチ、外見、衣装、シーンを選び、そのあと性格、名前、声を決めると、RYLA が選択用のベース画像を生成します。
一つの顔を参照シートに固定
キャラクターのベース画像を一枚選ぶと、RYLA がその顔の参照シートを生成し、新しい写真やクリップはそのシートから作られます。
一人のキャラクターの写真、動画、話すクリップ
仕上げた後、Studio ではテンプレートから新しい写真を生成し、画像から動画で静止画を動かし、Avatar Video で話すクリップを作り、動画スワップで既存のクリップに同じキャラクターを配置できます。
弱点を隠さない
Synthetic は、住まい、友人、ペットを備えた世界をインフルエンサーの周りに作り、そのクレジットは繰り越され、期限切れになりません。投稿が定番のキャストと舞台設定を軸にしているなら、Synthetic は今の RYLA よりも直接それに応えます。
Synthetic がまだ勝る点
Synthetic is ahead on world building and on credit terms. Its homepage lists Living Spaces, Social Circles, and Companions, so the same home, friends, and pets can come back in your influencer's posts, which suits story-driven UGC. Its pricing page lists a free Hobbyist plan with a 200 SC welcome bonus, paid plans from $19 a month, credit packs without a subscription, and credits that roll over and never expire. If a recurring setting and cast matters more to you than video and talking clips, Synthetic fits that more directly.
Synthetic から RYLA へ乗り換える
There is no import between the two products, so switching means building your character once in RYLA. This is the actual sequence in the RYLA builder:
- Pick a niche, then gender and style.
- Set the look: ethnicity, age, skin, eyes, face shape, and hair.
- Choose outfit and scene, then personality and a name, then a voice.
- Generate base images and pick the one that becomes your character.
- RYLA generates a reference sheet of that face.
- Finalize, then create new photos in Studio, motion with image-to-video, talking clips in Avatar Video, and swaps in Video Swap.
Here is one RYLA character from the showcase on this site, generated in two different scenes:
