Promptbook
Supercharge your use of large language models
๐ฆ Package @promptbook/utils
To install this package, run:
npm i ptbk
npm i @promptbook/utils
Utility functions used in the library but also useful for individual use in preprocessing and postprocessing LLM inputs and outputs
Here is a overview of the functions which are exported from the @promptbook/utils
package and can be used in your own projects:
Postprocessing
Sometimes you need to postprocess the output of the LLM model, every postprocessing function that is available through POSTPROCESS
command in promptbook is exported from @promptbook/utils
. You can use:
Very often you will use unwrapResult
, which is used to extract the result you need from output with some additional information:
import { unwrapResult } from '@promptbook/utils';
unwrapResult('Best greeting for the user is "Hi Pavol!"');
Templating
There is a function replaceParameters
which is used to replace the parameters in given template optimized to LLM prompt templates.
import { replaceParameters } from '@promptbook/utils';
replaceParameters('Hello, {name}!', { name: 'world' });
And also multiline templates with blockquotes
import { replaceParameters, spaceTrim } from '@promptbook/utils';
replaceParameters(
spaceTrim(`
Hello, {name}!
> {answer}
`),
{
name: 'world',
answer: spaceTrim(`
I'm fine,
thank you!
And you?
`),
},
);
Counting
Theese functions are usefull to count stats about the input/output in human-like terms not tokens and bytes, you can use
countCharacters
, countLines
, countPages
, countParagraphs
, countSentences
, countWords
import { countWords } from '@promptbook/utils';
console.log(countWords('Hello, world!'));
Splitting
Splitting functions are similar to counting but they return the splitted parts of the input/output, you can use
splitIntoCharacters
, splitIntoLines
, splitIntoPages
, splitIntoParagraphs
, splitIntoSentences
, splitIntoWords
import { splitIntoWords } from '@promptbook/utils';
console.log(splitIntoWords('Hello, world!'));
Normalization
Normalization functions are used to put the string into a normalized form, you can use
kebab-case
PascalCase
SCREAMING_CASE
snake_case
kebab-case
import { normalizeTo } from '@promptbook/utils';
console.log(normalizeTo['kebab-case']('Hello, world!'));
- There are more normalization functions like
capitalize
, decapitalize
, removeDiacritics
,... - Theese can be also used as postprocessing functions in the
POSTPROCESS
command in promptbook
Misc

package, every function is documented by jsdoc, typed by typescript and tested by jest.

๐ค The Promptbook Whitepaper
When you have a simple, single prompt for ChatGPT, GPT-4, Anthropic Claude, Google Gemini, Llama 2, or whatever, it doesn't matter how it is integrated. Whether it's the direct calling of a REST API, using the SDK, hardcoding the prompt in the source code, or importing a text file, the process remains the same.
If you need something more advanced or want to extend the capabilities of LLMs, you generally have three ways to proceed:
- Fine-tune the model to your specifications or even train your own.
- Prompt-engineer the prompt to the best shape you can achieve.
- Use multiple prompts in a pipeline to get the best result.
In any of these situations, but especially in (3), the Promptbook library can make your life easier and make orchestraror for your prompts.
- Separation of concerns between prompt engineer and programmer; between code files and prompt files; and between prompts and their execution logic.
- Set up a common format for prompts that is interchangeable between projects and language/technology stacks.
- Preprocessing and cleaning the input data from the user.
- Use default values - Jokers to bypass some parts of the pipeline.
- Expect some specific output from the model.
- Retry mismatched outputs.
- Combine multiple models together.
- Interactive User interaction with the model and the user.
- Leverage external sources (like ChatGPT plugins or OpenAI's GPTs).
- Simplify your code to be DRY and not repeat all the boilerplate code for each prompt.
- Versioning of promptbooks
- Reuse parts of promptbooks in/between projects.
- Run the LLM optimally in parallel, with the best cost/quality ratio or speed/quality ratio.
- Execution report to see what happened during the execution.
- Logging the results of the promptbooks.
- (Not ready yet) Caching calls to LLMs to save money and time.
- (Not ready yet) Extend one prompt book from another one.
- (Not ready yet) Leverage the streaming to make super cool UI/UX.
- (Not ready yet) A/B testing to determine which prompt works best for the job.
๐ง Promptbook (for prompt-engeneers)
Prompt book markdown file (or .ptbk.md
file) is document that describes a pipeline - a series of prompts that are chained together to form somewhat reciepe for transforming natural language input.
- Multiple pipelines forms a collection which will handle core know-how of your LLM application.
- Theese pipelines are designed such as they can be written by non-programmers.

โ FAQ
If you have a question start a discussion, open an issue or write me an email.
Why not just use the OpenAI SDK / Anthropic Claude SDK / ...?
Different levels of abstraction. OpenAI library is for direct use of OpenAI API. This library is for a higher level of abstraction. It is for creating prompt templates and promptbooks that are independent of the underlying library, LLM model, or even LLM provider.
How is it different from the Langchain library?
Langchain is primarily aimed at ML developers working in Python. This library is for developers working in javascript/typescript and creating applications for end users.
We are considering creating a bridge/converter between these two libraries.
Promptbooks vs. OpenAI`s GPTs
GPTs are chat assistants that can be assigned to specific tasks and materials. But they are still chat assistants. Promptbooks are a way to orchestrate many more predefined tasks to have much tighter control over the process. Promptbooks are not a good technology for creating human-like chatbots, GPTs are not a good technology for creating outputs with specific requirements.
Where should I store my promptbooks?
If you use raw SDKs, you just put prompts in the sourcecode, mixed in with typescript, javascript, python or whatever programming language you use.
If you use promptbooks, you can store them in several places, each with its own advantages and disadvantages:
-
As source code, typically git-committed. In this case you can use the versioning system and the promptbooks will be tightly coupled with the version of the application. You still get the power of promptbooks, as you separate the concerns of the prompt-engineer and the programmer.
-
As data in a database In this case, promptbooks are like posts / articles on the blog. They can be modified independently of the application. You don't need to redeploy the application to change the promptbooks. You can have multiple versions of promptbooks for each user. You can have a web interface for non-programmers to create and modify promptbooks. But you lose the versioning system and you still have to consider the interface between the promptbooks and the application (= input and output parameters).
-
In a configuration in environment variables. This is a good way to store promptbooks if you have an application with multiple deployments and you want to have different but simple promptbooks for each deployment and you don't need to change them often.
What should I do when I need same promptbook in multiple human languages?
A single promptbook can be written for several (human) languages at once. However, we recommend that you have separate promptbooks for each language.
In large language models, you will get better results if you have prompts in the same language as the user input.
The best way to manage this is to have suffixed promptbooks like write-website-content.en.ptbk.md
and write-website-content.cs.ptbk.md
for each supported language.
