Content — images, audio, video and links

What it is

Content is the library of files and links the AI can send to leads during a conversation. They can be product photos, audios, videos or lead magnets to improve your interactions in both replies and follow-ups.

The AI picks the right content based on the description you’ve given it and the moment of the conversation.

Content types

Type	Supported formats	Examples
Image	JPEG, PNG (max. 10 MB)	Catalog, price sheet, before/after photos
Audio	MP3, M4A, AAC, WAV, OGG, OPUS, WEBM, MP4 (max. 50 MB)	Voice note, recorded pitch
Video	MP4, 3GPP (max. 50 MB)	Demo, testimonial, short tutorial
Link	External URL	Booking page, website, payment link

Recommended size for Instagram

The sizes in the table are what ZeroChats accepts when you upload the file. Instagram is stricter and may refuse or degrade large files:

Type	Recommended limit for Instagram
Image	8 MB
Audio	25 MB
Video	25 MB

If you upload a file above that limit, you’ll see a warning when you pick it (Instagram may not send it) and another one when it goes out to a lead. The warning doesn’t block anything: the file is stored and sent anyway, because it usually works fine on WhatsApp.

GIFs can no longer be uploaded

Instagram only handles GIFs properly in direct messages sent from its own app. Sent from ZeroChats they arrive without their animation or don’t arrive at all, and the failure isn’t visible until the lead ends up without the image. That’s why GIFs are no longer accepted as Image content: if you try to upload one, you’ll see a warning and you’ll need to replace it with a JPEG or a PNG.

GIFs you had already stored are still there and still get sent, but they’re flagged with an amber warning badge in the three places you can run into them: the Contents list, the edit dialog, and the content picker inside a lead conversation. It’s the reminder that this file may not arrive properly on Instagram.

What to do with a heavy file

Compress the file or lower its quality until it fits the limit. If that’s not possible and Instagram is the destination, host it externally and share it as a Link content item.

PDFs and documents are not a content type

Only image, audio and video files can be uploaded. PDFs and documents are not supported as a file. To share a PDF (a guide, a price dossier, a lead magnet), host it externally (Google Drive, your website, etc.) and add it as a Link content.

How to configure it

Add a content item

From the Content tab, press Add Content and fill in the dialog:

Field	What it does
Name	Identifies the content in the library. E.g. Product image, voice note, resource link.
Content type	Image, Audio, Video or Link.
Upload file / Content URL	Upload the file from your computer or paste the URL if it’s a Link.
Sending Instructions	Describe when to send it (in replies and follow-ups), which type of customer needs it and which user responses should trigger it. The AI uses this text to decide who to send it to and when.
AI agents	Select which AI agents have access to this content.

When you’re done, Save. The content appears in the list with its assigned agents and the Edit and Delete actions.

Sending Instructions matter

The AI decides to send content based on its Sending Instructions. “file1” doesn’t work. Better: “Pricing PDF with monthly and yearly plans for group yoga classes. Send when the lead asks about rates or plans”. The more specific the description, the better the moment chosen.

Assign content to multiple agents

If you have several AIs, in each content item you choose which AI agents can use it. You can select specific agents, All AI agents or use the search. This means, for example, that the support AI doesn’t have access to the sales brochure.

Send order

The Send content before messages switch controls the delivery order:

• Enabled: the content (image, audio, link) is sent before the text messages. This is the default behavior.
• Disabled: messages go first, then the content.

How the AI uses it

1. It reads each content item’s Sending Instructions to understand when it fits.
2. During the conversation, if it detects that a content item is relevant, it picks it and delivers it together with the message.
3. ZeroChats tracks what’s been sent to each lead so the same content isn’t delivered twice.

Best practices

• Give clear names and descriptions: the AI is only as good as the Sending Instructions you write.
• Specify the lead profile each content is aimed at and the question or signal that should trigger it.
• Clean up the library: if a content item is no longer used, delete it so the AI isn’t confused.
• Use the correct Content type for each file. Remember PDFs and documents are not uploaded as a file — share them as a Link.
• Assign each content item only to the agents that actually need it.
