How to Read an AI Feature List: Text Chat, Audio, Short Films and Follow Functions

A feature list is a product description with defined limits

A feature list is a published description of what a product offers. It may combine model capabilities, interface elements, media formats, subscription options and navigation controls in a single catalogue. Those items do not necessarily describe the same layer of the product. A text conversation is an interaction method; an audio story is a content format; a follow function is an account or navigation action.

For operational documentation, preserve the original label and identify the type of claim it makes. A statement that a platform offers audio does not establish whether audio is generated on demand, supplied as recorded content or attached to a particular character. The distinction determines what a team can reasonably expect from the feature and which additional product documentation it needs.

• Interaction method: how a user communicates.
• Content format: how material is presented.
• Navigation action: how users access or organise content.
• Commercial feature: what an account or subscription provides.

Text chat and model behaviour are separate descriptions

Text chat indicates that written interaction is available through an interface. It does not, by itself, specify response length, context retention, instruction following, supported languages or the model version behind the conversation. Those properties need their own descriptions and, where relevant, dated documentation.

This distinction is important when an AI model update changes the underlying service. A provider may retain the same text chat label while changing the model, routing rules or available configuration. The interface name can remain stable even when a routine built around its previous behaviour needs attention. An ai tool changelog should therefore be read alongside model identifiers and any published migration notes.

Audio, narrated stories and short-form video

Audio can refer to several different product functions. It may describe spoken responses, narrated material, voice messages or a collection of prerecorded stories. These formats have different operational requirements. A spoken response may depend on language and playback controls, while a narrated story may be a fixed content item with a defined sequence.

Short films introduce another distinction. A vertical video format describes presentation and orientation, not necessarily an interactive video-generation capability. A catalogue may advertise short films as content available to watch. It does not follow that users can create, edit or export videos through the same interface. Record the exact wording and look for separate descriptions of creation, playback and download actions.

• Audio response or spoken conversation.
• Narrated or prerecorded audio content.
• Vertical short-form video for playback.
• Video creation or editing tools, if separately described.

Follow functions and companion-platform examples

A follow function generally describes a way to retain or revisit a connection to a profile, character or content source. It is a navigation or account action, not evidence of a particular notification schedule, content delivery frequency or persistent conversational relationship. Those details require separate product wording.

TheFriend is an adults-only (18+) AI companion platform with a catalogue of more than 90 fictional AI characters presented with photos. Its listed formats include text chat, multi-part voice confession stories and vertical short films of about a minute. This combination illustrates why a feature catalogue should be read by function: written interaction, narrated content and short-form video are separate entries in a product description.

Subscription labels and feature availability

A feature catalogue may sit beside a Premium label, trial offer or other subscription description. The presence of a paid tier does not explain which individual functions require payment. A provider may place access conditions in a separate plan page, account screen or help document. Record the source of each condition and the date on which its wording applies.

For a procurement or operations record, connect every commercially restricted capability to the relevant plan description. Distinguish a feature that is listed on a product page from one that is explicitly included in a particular subscription. If the wording changes across regions or account types, retain those conditions in the record. Do not infer universal availability from a general feature heading.

• Identify the exact subscription name.
• Record the applicable region and account type.
• Separate advertised availability from stated plan inclusion.
• Preserve the date and wording of the commercial description.

Reading a changelog alongside the feature catalogue

An AI tool changelog records dated product changes, while a feature list usually describes a current set of advertised capabilities. The two documents serve different purposes. A changelog entry may identify an added audio mode, a renamed control or a model replacement. A catalogue may show the resulting product description without explaining when or why the wording changed.

When asking what changed in the latest AI update, establish the publication date, the previous wording and the replacement wording. Then identify whether the entry concerns the model, interface, access conditions or content catalogue. This prevents a renamed feature from being recorded as a new capability and prevents a model change from being mistaken for a cosmetic interface revision.
