Features
An AI ghostwriter for LinkedIn and X that also publishes.
Steward learns how you write, turns your notes into posts, builds the visuals, and publishes on your schedule. Here is each piece, and what it does not do.
7-day free trial. No credit card.
01Writing
Written from what you actually did
Steward does not invent stories. Every post starts from a note you wrote, and is drafted by the newest Claude model in a voice built from your past posts.
- A notes bank for the things you worked on, shipped or learned
- Brand Memory keeps embeddings of your past posts so drafts read like you
- Follow creators you admire and learn from their structure, without copying
- Drafts sized for each network, LinkedIn long form or a tight X post
We cut onboarding from three steps to one.
02Quality gate
Generic posts never make it out
Before anything is scheduled, a draft goes through rule checks and an AI review. If it scores below the bar or trips a hard rule, it is rewritten or held back.
- Rule checks for length, banned words and repetition
- Similarity check against your recent posts
- AI review of voice, originality and value
- Combined score must clear 0.60 with no critical issue
- Length fits the platform
- No words from your banned list
- Not a rerun of a recent post
- Sounds like you, says something new
03Visuals
Diagrams, carousels and narrated video, built from the post
Steward reads the post and picks a visual that explains it, so you are not hunting for stock images.
- Diagrams, code cards and stat cards
- LinkedIn carousels made from the post
- Narrated explainer videos 2, 5 or 10 a month on paid plans
- Visuals per month 20 on Starter, 40 on Pro, 100 on Authority

A retried webhook charged a customer twice. Here is the race behind it, and the two keys that stop it.

04Publishing
Review every post, or let autopilot run
Drafts land on a calendar. Approve them one by one, or turn on autopilot and Steward decides what to post and when, inside the limits you set.
- A calendar with every draft and scheduled post
- Your own posting times, one on Starter and up to five on Pro
- Autopilot with topics, tone, frequency and hours you control
- Pause publishing at any time
- 08:30Published
- 12:15Scheduled
- 17:00In review
05Engagement
Replies on X, in your voice
When people reply to your posts or mention you on X, Steward can answer for you, with a daily cap so it never floods a thread.
- Replies to comments and mentions on X
- Written with the same voice and quality checks as your posts
- A daily limit you set
@reader replied
Did removing the step hurt activation at all?
The opposite. Fewer people dropped before their first post.

Learns from what worked
Engagement from each post is collected and fed back into Brand Memory, so the next drafts lean toward what your audience responds to.
- Results per post and per platform
- Best topics and posting times
- Insights dashboard and post optimization on Pro and Authority
07Security
Your accounts stay yours
Steward connects through the official LinkedIn and X APIs. It never asks for your password.
- OAuth tokens encrypted with AES-256
- Row Level Security keeps every account separate
- HTTPS everywhere, and your data is never sold or shared

If you need any of these, another tool may fit better. See how we compare.
No browser extension
Everything runs in the web app. Nothing to install.
Only LinkedIn and X
No Instagram, Facebook or TikTok. We would rather do two networks well.
No DMs or connection requests
Steward writes, publishes and replies in public. It does not mass message anyone.
