Etto is available in two tiers: Etto Standard and Etto Premium.

Etto Standard

Complimentary feature. Included in all current Heretto CCMS licenses and available to all eligible^* Heretto customers. Includes all default Etto capabilities. Has a token limit of 600,000 input tokens** and 150,000 output tokens** per customer per month.

Etto Premium

Available for purchase to any eligible^* customer. Includes all default Etto capabilities, 600,000 input tokens^** and 150,000 output tokens^** per user per month, the ability to configure custom rules, as well as additional future capabilities.

^*Eligibility criteria include pricing, service agreement, CCMS version, and software upgrade schedule. Eligibility criteria are not related to the CCMS license type. For details, contact a Heretto representative.

^**You can think of tokens as chunks of words. When Etto processes content, it breaks it up into a number of smaller tokens that it uses to process the request and prepare a response. Input tokens are all tokens that are sent to the AI API for processing, which includes prompts, the content Etto analyzes to provide a response, as well as custom rules (Etto Premium). Output tokens are all tokens the API sends back to the user in the form of an Etto response.

Discover who can use Etto, the Heretto Copilot, understand how to interact with Etto, as well as the measures ensuring your data security.

Who can use Etto

• Currently, Etto is available to users with the Administrator, Author, and Editor/Manager roles in Heretto CCMS.

• Etto is not available to users with the Reviewer role. This is true for both default and custom Reviewer roles.

Prompting Etto

• To rewrite a specific portion of content, we recommend selecting it, then providing Etto with a prompt. For example, before you give Etto a task, select the content, like a paragraph, that you want Etto to modify. Etto will mark the existing content to be replaced and suggest an updated version.

• To keep the existing content in the document, we suggest copying and pasting the existing content into the Etto window along with the prompt. Etto will suggest a change but leave the existing content intact.

• Every time you open Etto, a new conversation session starts. Every conversation is a separate session. Etto does not store any data between sessions. This enables Etto to provide faster answers by using fewer resources.

• Because of the nature of Large Language Models (LLM), using the exact same prompt multiple times might result in slightly different outputs.

Etto activity

• You don't receive notifications about suggestions added by Etto (expected behavior)

• Etto activity is not logged in the Activity interface but your responses to its suggestions are.

Information security

• Etto runs entirely within the Heretto CCMS infrastructure.

• Heretto does not use customer data to train Etto.

• Customer data is not stored in any of the Etto Artificial Intelligence (AI) models or databases.

• Conversational information exchanged with Etto never leaves the Heretto CCMS infrastructure.

• Every conversation is a separate session. Etto does not store any data between sessions.

Etto, the Heretto Copilot can help you create high-quality structured content by answering questions, providing best practices, as well as creating, revising, and restructuring content. Read some examples of how Etto can be of assistance.

Proofreading a Document Based on Custom Rules (Etto Premium only)

With Etto Premium, you can specify custom writing rules that Etto follows when responding to prompts. That makes Etto a better companion for Authors or even a great Editor. Etto can help you with:

• Proofreading an entire document to ensure it follows all custom rules.

• Proofreading a selected portion of a document to ensure it follows all custom rules.

Analyzing and Improving a Document

Etto can save you time when improving existing content. Etto can help you with:

• Analyzing an entire topic and making multiple changes in one operation. For example, Etto can analyze a topic and suggest changes to improve grammar, punctuation, capitalization, and style, as well as correct facts, inconsistencies, content structure, and more.

• Modifying content on a granular level. Etto can find and remove or replace instances of a word or snippet of text in a topic. For example, it can replace all instances of the following with this or remove a portion of a sentence.

• Making factually correct draft content sound better in English. This is especially handy when you feel like your writing could use some polishing.

• Making a piece of content more concise.

• Splitting chunks of content into smaller, structured pieces. For example, a paragraph into an unordered or definition list.

• Rewriting passive voice into active voice.

• Rewriting titles based on content present in the topic.

• Checking for DITA validation errors and fixing some validation errors.

Restructuring Content

Etto can also help you move from unstructured to structured content, including:

• Converting unstructured content to structured DITA XML.

• Converting content from one structure to another. For example, Etto can turn a list into a table or a table into a definition list or an ordered list into steps.

• Wrapping content with DITA elements. For example, Etto can find all instances of paragraphs that start with “Note:” and replace them with the note element.

Creating Content

Etto can assist you when creating content in multiple ways, including:

• Writing release notes based on the contents of a ticket. For example, you can paste the contents of a Jira ticket into Etto and ask it to write a release note based on it.

• Writing and updating short descriptions, titles, and other content by analyzing existing content.

• Writing generic, reusable content, such as notes and warnings.​

• Creating definitions of commonly known concepts. Etto has extensive knowledge which enables it to create terms and definitions effectively.

• Creating standard DITA structures such as tables, lists, and sections. You can specify the size and other attributes of these structures.

Performing Complex Table Operations

Apart from creating new tables, Etto can also perform all kinds of operations on existing tables, including:

• Adding, moving, and removing rows and columns in a table

• Splitting and merging cells in a table

• Adding table headers

• Bolding rows

• Setting column width

• Ordering rows alphabetically

Enriching Content with Semantics and Metadata

Etto can identify pieces of content and wrap it with DITA elements as instructed. It can also apply metadata to DITA elements for you. For example, Etto can help you by:

• Wrapping pieces of content in semantic DITA elements like uicontrol, menucascade, note, codeblock, or codeph.

• Adding attributes to DITA elements. For example, adding values to the audience or product attribute for DITAVAL filtering.

• Specifying elements properties. For example, setting the note type attribute to warning.

• Adding metadata, like keywords, to the topic prolog element based on the content in that topic.

Providing Guidance

Etto is trained in the DITA standard. It also knows a lot about the world. This means it can help you in areas like:

• Building a specific structure in DITA or using a specific DITA element

• Answering questions about DITA elements

• Providing information about common concepts

Etto Limitations

These are the current known limitations of Etto. Please bear in mind that Etto learns every day to better assist you in your everyday tasks.

• Etto works within the context of one DITA topic at a time. It cannot see or modify the content of other topics or work across multiple files in the CCMS.

• Etto cannot link to other resources in the CCMS.

• Etto cannot create new files. However, it can create new subtopics within your current working topic that you can then manually move into a new topic.

• Etto can turn descriptive text into DITA tasks but places the task structure in your current working topic. You can then manually move the task structure to a new task topic.

• Etto cannot convert large unstructured amounts of content into a structured DITA topic but it can convert smaller pieces of unstructured content or improve structure within a topic.

• Etto can translate content but this capability is considered experimental and untested. Use caution when using content translated by Etto and work with a Localization Services Provider (LSP) to ensure content is localized properly.

• Etto understands languages other than English, but this capability is considered experimental and untested. Use caution when requesting assistance in languages other than English, as the results may vary.

• Etto has not been tested on specialized DITA content types. It currently doesn't know about specialized content rules or DTDs.

• Etto is not fully supported in the Edit Content window where you can work on reusable content. is not fully supported. We recommend opening the reused content in the Content Editor.

• Etto is not supported in the locales interface where you can edit localized content directly in the CCMS.

Custom rules enable you to set custom rules in Heretto CCMS. These rules guide responses provided by Etto, the Heretto Copilot. Custom rules are only available with Etto Premium.

With Etto Premium, users assigned the Administrator role in the CCMS can add custom rules for the copilot. The rules are set for all users who work with Etto. Etto follows them whenever it responds to a prompt.

Custom rules are added in the Etto Admin interface available in the Administration interface. Custom rules are sent to API every time a user sends a prompt to Etto. This means that custom rules count towards the Etto token limit. To minimize impact, the custom rule input field is limited to 1,500 characters.
