We're excited to introduce enhanced collaboration, search and authoring features for our Arcane 1.1.0 release!

Now, you can share Collections with colleagues using a simple Share button, prioritize official content in results at an organization level using Tiered Content, create Email content faster than ever.

We are also releasing infrastructure that will power our Arcane 1.2.0 release with advanced Image search for both users and AI.

Existing users can try these features now.

Major Features

Tiered Content

Tiered Content enables organizations to prioritize search results by categorizing documents into various importance levels based on filters. This enables Arcane to surface the most relevant documents when a topic is present across many types of documents, without impacting query performance. Organisations can not only define Tiers, but also set their relative level of importance to adjust the results further.

Tiers can be defined as simply as the example above, they can also be based on multiple criteria, or literally rely on a list of specific documents - it’s about what makes sense to your Organisation.

This global Tiering can always be overridden if a user is -for example- manually applying a filter to focus their interactions to content from a local market. In that case their queries will be managed by the user defined settings.

Reach out to the Anthill team if you would like to configure Tiered Content for your organization!

Shared Collections

You can now share your collections through a simple link, offering a seamless way for others to access your curated content. Upon clicking the share link, recipients are directed to a new conversation in content assist.

If a user adds the collection, they have access to a read-only version of the collection which is updated automatically whenever the collection owner makes changes to the original collection.

Note that if the original creator uses the link, it opens the existing collection without creating additional shared versions, and duplicate collections for the same shared content are prevented by validating link identity before creation.

Image Import

The Arcane platform now uses multimodal import for Image assets, allowing Arcane to generate detailed understanding of the contents of each image. This import capability will surface in user features in the Arcane 1.2 release which will allow users (and the AI) to search for images that match certain requirements using natural language e.g. “Find an image of a grandmother reading to a child” or “Find a Remepan 10mg pack shot”.

Authoring Updates

Faster AI Content Creation

We have improved the process used by Arcane AI when generating new content, reducing the time from prompt to content creation.

Faster Collection Summaries

We now create Collection Summaries over twice as fast as in Arcane 1.0 by using the Claude Haiku 3.5 model.

Better Persona Styling when creating multiple Content Blocks

With this update, your Personas, Segments, Style and Editorial Tone are applied more consistently when generating multiple layouts at once via a prompt like “Create and email about efficacy and safety data”.

This update corrects instances where context prompts were inconsistently applied, enhancing reliability in content creation across diverse topics.

Updates to My Creations

Emails are now listed in correct chronological order, and the My Creations view updates with the latest creation if you switch from an email directly to My Creations.

Security

Security Updates

The Arcane application serves content as a static webpage enhanced via an HTTP API, with authentication managed by Auth0. This setup secures both user access and role assignment. Every API endpoint is protected: user endpoints require Auth0 token validation, while machine endpoints utilize IAM for access control. Communication between internal components likewise employs IAM-protected messaging and queues. Public endpoints are absent, directing security attention to potential DDOS vulnerabilities at the validation middleware. To fortify defenses, WAF protection is now enabled for both our API and CloudFront distribution.

Web Application Firewall (WAF) Configuration for API Gateway and CloudFront

Arcane API and web distribution security has been improved with updates to the configuration and deployment of Web Application Firewalls (WAF) directly configured via Terraform. This update allows efficient management of WAFs on both the API Gateway and the CloudFront distribution. Each WAF is pre-configured with request throttling to prevent abuse and ensure that Arcane remains responsive under varying traffic loads.

Data Connectors

S3 Connector

The new S3 Connector offers a streamlined way to ingest documents into Arcane directly from an S3 bucket. This feature facilitates the processing of Danone’s input, which includes PDFs and associated source files, through a structured import mechanism. Documents are paired with metadata outlined in a supporting spreadsheet, ensuring accurate import and classification with a unique S3 external ID. The connector enables a two-step process: initial document creation and update, followed by vectorization and final import.

Bug Fixes

Handle Empty Collections

Arcane now checks that your Collection has at least one document in it before entering Authoring mode. We also now correctly allow users to Share empty Collections.

My Creations Error Fixes

You can now open and edit your saved contents in My Collections without encountering server errors. Previously, some users experienced errors and encountered issues saving new content. The underlying cause has been resolved, allowing you to access your documents smoothly.

'New' Button in Authoring Mode

In Authoring mode, the “New” button will correctly clear the current email and allow the user to begin creating a New Email

Thumbnail Display in My Creations

Fixed an issue where some users were not seeing thumbnails of their saved documents in the My Creations view
