Writes in each person's voice
Drafts for the company page, founders, executives and employees from each person's best posts. Imagine AI started as the operating system for ghostwriting teams, so sounding like you is the core of the product.
The verdict
Hey Sid runs your ads. Imagine AI runs your team's LinkedIn content.
Hey Sid fits a mid-sized, sales-led B2B company that wants paid reach to buying committees plus a ghostwriter from one vendor. Imagine AI fits teams that want the company page and their people posting consistently on LinkedIn, aimed at their ICP and measured in the CRM.

Choose Imagine AI if

- You want a graphic drafted with every post, on brand, from your brand kit.
- You want content and outreach from one agent, aimed at the engagers your posts pull in.
- You want the company page, founders, executives and employees on one calendar, with unlimited teammates.

Hey Sid vs Imagine AI, in five differences
Each one ends with the line that matters.
[01]
Paid reach versus organic content
Hey Sid's Always On runs person-targeted ads across LinkedIn, Meta, Google and display. Imagine AI does not run ads. Its agent creates your team's organic LinkedIn content and does the outreach too: comments, connection requests and messages, aimed at the people your posts pull in.
Pick Hey Sid for paid ads.
[02]
Human ghostwriter versus agent
Hey Sid's Authority Builder is human ghostwriting: a strategist writes four LinkedIn posts a month per person from a discovery interview, with a three month minimum. Imagine AI's agent drafts posts and graphics for the whole team from your content filesystem, and each person reviews, approves or edits.
Interview-led volume versus agent-led volume.
[03]
Both report pipeline
Hey Sid connects ad exposure to HubSpot opportunities and revenue. Imagine AI matches engagers on your content against HubSpot or Salesforce, traces each closed deal to its first content touch and hands sales a weekly list of engagers matched to your ICP, with the data over an API for your outbound tools.
Ad influence versus content touches.
[04]
Data behind the drafts
Imagine AI's agent reads a public benchmark of 1,000+ B2B companies, so posts are aimed at the post types and formats that work in your industry.
Every draft is checked against what works.
