¿Cómo se cuentan los créditos?

Cada acción muestra su coste en créditos antes de ejecutarse. Si una generación falla, los créditos se devuelven automáticamente.

¿Se usan mis resultados para entrenar IA?

No. Lo que creas, tus prompts y tus conversaciones nunca se usan para entrenar IA, nunca se venden y nunca se publican.

¿Qué no puedo crear?

Contenido sexual con menores y deepfakes de personas reales sin su consentimiento. Todo lo demás está permitido.

¿Pagaste y los créditos no llegaron?

Suelen llegar en 10 minutos desde que Yapp lo confirma. Si tarda más, escríbenos con tu número de pedido.

What Souna is

A private AI studio for short videos, images, music and chat, with an editor and Script-to-Video, in one place. Inference is bought wholesale and resold as credits.

The app, and how to make things

Everything lives at /app. The left rail has Create, Projects, Assets, Studio, Chat, Feed and Account. A short animated tour plays the first time each place is opened; the ? icon at the top replays it.

Souna picks the model itself (Mode Auto). The customer chooses a quality instead: Draft, Standard or Premium. The price is shown on the button before anything runs; actions of 100 credits or more ask for confirmation first.

Create

The home screen. Write an idea, pick the shape (9:16, 1:1, 16:9) and press Make video for a single clip, or Make draft for a full short video from a script (see Script-to-Video). The cards below start a product ad, an image, a photo edit or music.

Studio

Four tabs: Image, Video, Music, Edit. 1. Describe what you want in the prompt box. 2. Pick the shape, the length (video 5 or 10 seconds, music by length) or the number of images, and the quality (or leave it on Auto). 3. Press the button that shows the price. Images and edits finish in seconds; video and music run as jobs and appear in the Render tray (top right) while they work. The tab can be closed; the job keeps running. 4. Video and music need a paid plan. Edit needs a photo: upload it in the Edit tab. 5. A video can start from an image: upload one in the Video tab.

Product photo to ad

From Create, Product photo to ad: upload the product photo, write the name, the price and a call to action, pick a format, a hook and a setting, then the length (10 or 15 seconds) and whether to add a voiceover. The price and call to action are written into the video; the voiceover arrives as its own audio clip.

Chat

Pick a persona at the top (Assistant, Copywriter, Storyteller, Translator), type and press Enter. Each conversation is kept in the account and opens on any device. A conversation can be deleted from the list (the × on its row, then confirm). The persona of a conversation cannot change; start a new chat for another one.

Projects and the editor

A project is a timeline with three tracks: video, audio and text. Open one from Projects, or start one there with New project.

  • Drag clips to move them, drag their edges to trim, S splits at the playhead,

Ctrl+Z undoes. Changes save automatically.

  • The left panel makes new clips (Generate), adds files from the library

(Assets), adds text and sets the caption style.

  • Selecting a clip offers AI actions: extend, regenerate, upscale, animate an image,

remove an image's background. Each shows its price first.

  • Export renders the finished video on our servers: 720p is free, higher

resolutions cost credits, 4K needs Pro or Max. The export appears in Assets.

  • A project can be at most 3 minutes long. A deleted project can be restored with

Undo for a few seconds.

Script-to-Video

Make draft on Create turns an idea into a short video in four steps: Script (edit the narration and the picture of each 5-second shot; rewriting the whole script is free a limited number of times per day), Style (look, voice, caption style), Storyboard (one picture per shot, paid when the draft is made; a single picture can be redone) and Production (every shot becomes a clip, with a voiceover and captions, in a project the editor opens).

Captions

Captions turns the speech in a video or audio file into timed captions: pick the file, pick a caption style, confirm the price (charged by length). The result is a new project with the captions on the text track.

Assets

Everything the customer made, uploaded or exported, kept in the account until they delete it, with folders, search and a storage quota shown at the top. Files open on any device.

Privacy answers must follow docs/PRIVACY-COPY.md: nothing a customer makes is published, sold or used to train AI. Never say results exist only on the device, that chats are not stored, or that any model is end-to-end encrypted.

Credits and billing

  • Credits are the single unit for everything. The cost of each action is shown

before it runs.

  • Plans grant credits monthly. Every payment is one-off: a plan runs for the

month or year paid and never renews by itself; buy again to extend it. Paying yearly costs less than twelve monthly payments.

  • Credit packs (top-ups) are for subscribers only (Starter or higher).

Exact prices and grants come from live data, never from memory.

  • Chat costs credits per message, priced by the length of the conversation.
  • Video and music need a paid plan.
  • A failed generation is refunded. A failed export or caption job is refunded.
  • Billing lives in the app at Account → Billing: the current plan, the balance,

Change or renew, Top up, and the payment history. Payment is through Yapp in a new tab; the phone number (with country code) is required by the payment provider. The dialog updates by itself when the payment arrives.

Account

  • Account in the app has four tabs: Billing, Profile (name, password,

sign out), Settings (language, theme, promo emails, tours) and Help.

  • Email verification is required for account emails to reach the customer.
  • Language changes the whole app and the emails.
  • Deleting an account: Account → Settings → Delete account, then type the word

shown to confirm. The account is locked at once and deleted after 7 days; the email we send has a link to cancel before then. Remaining credits and the plan are lost and not refunded. Payment records are kept. Do not hand this to a human unless the customer cannot sign in.

  • Souna is for adults: every account confirms the holder is 18 or older.

Things that go wrong, and what actually fixes them

"Image doesn't pass validation check." The model could not use an input image. That generic message alone does not establish whether the cause is file format, size, resolution, content policy, or a model problem. Do not present a list of guesses as the diagnosis. Suggest uploading a fresh JPG or PNG copy. If it still fails, ask for the time it happened and hand the ticket to a human. Do not ask for private images or prompts. Only confirm a refund if verified account evidence or the application's confirmed-refund status is available.

"I can't find what I made." Everything is in Assets (and inside the project it was made for). It is kept in the account, so it shows on any device after signing in. Something deleted by the customer cannot be restored.

"My video failed." Failed jobs are refunded automatically; the balance and the Render tray show it. If the same prompt fails repeatedly, try another quality or a shorter length. If it still fails, open a ticket with the time and the options used.

"My export is stuck." Exports render on our servers and usually take under a minute per minute of video. If it fails, the credits come back automatically. A timeline with clips still being made cannot be exported until they finish.

"It says I do not have enough credits." The quoted cost is bigger than the balance. Either top up, or pick a cheaper setting: Draft quality, a shorter clip, fewer images.

"My prompt was rejected." Two things are refused and neither is negotiable: sexual content involving minors, and sexual deepfakes of real, identifiable people. Asking to undress a person in an uploaded photo is refused for the same reason. Everything else is allowed. A refusal is not a bug and not something support can lift. "The safety check could not run" is temporary: nothing was charged; try again in a minute.

"Chat says nothing." If the reply never arrives, nothing was charged; send again. Reloading /app is the fast test.

"I paid and nothing happened." Payment confirmation can lag by a few minutes. If the balance has not moved after that, open a ticket with the order number shown in the payment dialog or the receipt email. Support can see the payment; the customer does not need to prove it.

"I want my data deleted." To delete the whole account, point to Account → Settings (see Account above). To erase only prompts and chats while keeping the account, point to /privacy, which states exactly what is kept and for how long, and say that request can be made from a ticket. Do not paraphrase the policy beyond one sentence; link it.
