AI models

Pick the AI model that fits your book

ebo-ok has three writing models and two cover models. This page sums up which kind of book each one suits and how to use it, with sample covers drawn from the same brief so you can compare.

Writing models

Used to draft tables of contents, chapters and sections. All three write Thai; they differ in how carefully they write, how long a chapter they can write, and what they cost in credits.

  • Fast and economical

    Ebo Lite

    The entry model: the fewest credits and quick turnaround. Suits straightforward content and chapters that are not too long.

    Good for

    • How-to guides and step-by-step knowledge books
    • First drafts, trying out ideas, or outlining a table of contents
    • Short books whose chapters stay at medium length
    Longest chapter
    Medium
    Medium chapter
    3 credits
  • Balanced quality and price

    Ebo Pro

    Builds an argument step by step more reliably, reads more fluently, and can write long chapters. Works for most books.

    Good for

    • Business, finance and self-improvement books
    • Non-fiction you plan to sell
    • Picture books and children’s books that should be fun to read
    Longest chapter
    Long
    Medium chapter
    8 credits
  • Most thorough

    Ebo Max

    For writing that needs the most depth and continuity. No cap on chapter length, and the most credits per job.

    Good for

    • Novels and short stories that must keep characters and tone consistent
    • Textbooks, academic writing and specialist topics
    • Very long chapters, or books where the AI decides the length
    Longest chapter
    Unlimited
    Medium chapter
    24 credits

Every job’s cost for each model is in the credit price table.

Which model for which book

A suggested starting point for each kind of book. You can switch models at every step — start with the suggestion and adjust to what you get.

How to use them

  1. 1

    Choose a default when you create the book

    It is used for every step of that book — the table of contents, chapters and sections.

  2. 2

    Switch models at any step

    For example, draft the table of contents with one model and write the key chapters with another. Each step is charged at the model it used.

  3. 3

    Chapter length depends on the model

    Models write to different lengths. A length a model cannot write is not selectable — switch to a higher model first.

  4. 4

    Regenerate if it isn’t right

    A regeneration is a new job and uses credits at the selected model’s rate. Say clearly what you want changed before you run it again.

Credit-saving tip: outline and draft the table of contents with Ebo Lite, then write the real content with Ebo Pro or Ebo Max once the structure is settled.

Cover models (E-cover)

Draws a book cover, with the title in Thai, from your book’s details. The cover model is chosen separately from the writing model, and every run gives you 3 covers to choose from.

  • Fast, economical covers

    E-cover 3 Flash

    Tidy, readable layouts with fewer elements — good for trying several directions before settling on one.

    Good for

    • Guides, textbooks and knowledge books that want a clean cover
    • Trying several styles to find a direction
    • Books that want a simple overall look

    10 credits / run

  • More detail

    E-cover 3 Pro

    Sharper images and lettering, and usually more design elements and detail — for covers where the artwork has to stand out.

    Good for

    • Novels, picture books and books where the cover sells
    • Long titles, or covers that need crisp lettering
    • Books ready to go on sale

    20 credits / run

How to make a cover

  1. Open your book and go to the cover step
  2. Pick a cover style, or let the system choose one from your content
  3. Choose an E-cover model, and optionally type what else you want
  4. Pick your favourite of the 3 covers — or run it again if none is right

Already have a cover?

Upload your own cover file in the same step — it uses no credits.

Compare covers: same brief, different model

These covers were drawn by ebo-ok’s real cover system from exactly the same title, description and style — only the model differs (E-cover 3 Flash vs E-cover 3 Pro). Click a cover to see it full size.

Money guide

ออมเงินฉบับมนุษย์เงินเดือน

A money guide for salaried workers: splitting a salary, building an emergency fund, clearing credit-card debt and making a first investment.

Cover style: How-to guide

Both models spelled the title correctly. Pro added a blurb sticker, a label on the coin jar and a checklist; Flash kept a cleaner layout.

Novel

เงาในสายฝน

A woman returns to her riverside hometown after her mother’s death and finds old letters that reveal a family secret, in a rainy season that will not end.

Cover style: Literary

Both carry the quiet, muted mood of the literary style. Pro stages the scene with more depth and more detail in the room.

Picture book

หมีน้อยกับดาวดวงสุดท้าย

A bedtime story for ages 4–7: a little bear sets out to find a star that fell from the sky, makes friends on the way and learns about courage.

Cover style: Children's

Both drew appealing characters and a readable title. Pro added more characters and more background detail.

Sample covers drawn in September 2026. Yours will not match these exactly — the AI draws something new every time, and the models may have been updated since.

ebodio — AI narration

ebodio turns your book into natural-sounding Thai narration with AI. Listen right inside the reader — every book uses the same consistent voice.

A natural Thai voice that reads accurately

In our tests, transcribing the narration back into text gave under 1% errors. Numbers and units come out right too — “8–12 Hz” is read in Thai as “eight to twelve hertz”.

Listen to a sample

AI-generated voice

  • Tables that make sense when heard, the author’s own words

    Tables are told as sentences, one row at a time, and illustrations are read from their captions. Everything else is read exactly as the author wrote it — nothing added or reworded.

  • Highlights and scrolls along

    The paragraph being read is highlighted and the page scrolls with it (you can turn this off). Tap any paragraph to start listening from there.

  • Keeps playing with the screen off

    Control playback from the lock screen, change the speed from 0.75× to 2× without distorting the voice, move on to the next chapter automatically, and pick up where you left off.

  • Starts in seconds

    No waiting for the whole book — the audio is prepared one chapter at a time.

  • Pay once per book

    Paid in credits, priced by the book’s length, and you always see the price before you confirm. If you bought the book, you can always listen to the version you bought.

  • For your own books too

    Owners can turn it on — even for a book written just for themselves and never published. After editing, update the audio and pay only for the parts that need new audio.

ebodio vs the browser voice

The reader also offers a free voice from your browser. Pick the voice you like and switch any time.

Frequently asked

Can one book use several models?

Yes. The model chosen when you create the book is only the default — you can switch at each step, and the cover model is chosen separately from the writing model.

Why is every result different?

The AI generates something new every time, so even the same brief and model give somewhat different results. If it isn’t right, describe what you want more precisely and run it again.

Will the models change or improve?

We keep improving the models behind each tier. The names may stay the same while their abilities improve with updates. Current credit prices are always on the pricing page.

The Thai lettering on my cover is wrong — what can I do?

The AI sometimes draws Thai letters, vowels or tone marks incompletely. Run it again, switch to E-cover Pro, which usually letters more crisply, or upload your own cover.

How long can I listen after paying for ebodio?

You pay once per book. If you bought the book, you can always listen to the version you bought. If it’s your own book and you edit it, you can update the audio and pay only for the parts that need new audio.

Can I listen without spending credits?

Yes. The reader has a free browser voice, but how it sounds depends on your device — some have no Thai voice, and most phones stop reading when the screen turns off. For a natural Thai voice that keeps playing with the screen off, choose ebodio.
