Biggly Duet Bundles

A Biggly Duet is our premium bundle. You get:

A full novel or novella, written by a real author
The whole world of that book, as knowledge nuggets
Its lead AI character, to talk with and keep
A role of your own to play, opposite them

Here’s an example of a Duet, the Pirate’s Prize, a 98 page novella, which also comes with Finn, the character, and Anne, the persona for you to play as. This Biggly Duet is one of 3 given FREE with Biggly:

Read the full-length human-written novel…

Then re-live the story with the Biggly character!

The Finn AI character follows the book’s plot, so you can relive it – your way!

Bring your own book

Hand Biggly an epub or PDF of a novel you love, and it reads the whole thing, then builds the characters, their world and the storyline for you to step inside.

As a professional author creating an official add-on character, or as fun and informal fan-fiction, Biggly makes it easy to get interactive!

Mobile Friendly

Continue your chats and adventures on your phone or tablet!

Companions that remember you

As well as Story characters that follow the plot, Biggly Bot has Companion characters, with their its own unique memory system, so the character can actually remember what you’ve talked about!

Press a button and it remembers for you, and – very important – you can easily add, edit or delete each character’s memories.

Fun, freedom and features:

Easy to use, with real freedom – a very deliberate design philosophy of Biggly is to be a powerful tool that you own and is easy to use.

If you just want to describe a character and start chatting you can, or if you prefer, you can craft deep, story-following characters or fan-fiction – then step inside their world!
