Generic AI writing gets throttled on LinkedIn
LinkedIn's 2026 algorithm rewards dwell time and saves over likes. Posts that read as AI earn neither — readers scan and scroll. Generic AI tools like the default ChatGPT prompt produce drafts that converge on a recognizable AI tone, which is exactly what the algorithm now penalizes via low dwell time. Paying for shallow AI is paying for less reach.
- Generic AI tone earns low dwell time → algorithm throttling
- Default ChatGPT output reads as AI to humans → low save rate
- Re-pasting voice samples every session is high-friction and inconsistent
- Most AI tools have no voice training at all — output is the same library tone for everyone
How it works
- 1
Pick the platform and length
Choose LinkedIn or X, then pick short / medium / long. The AI adapts tone, format, and character count to the target platform automatically.

Give a topic or paste a source
Type a topic, paste a tweet you want to expand, or use a source URL. Optionally add an "angle" — a contrarian take, a personal hook, a specific frame.

Get a draft in your voice
The AI generates a draft using your Content DNA (voice training). Edit in place, regenerate, or accept and schedule.

Capabilities
Voice-trained generation
Drafts match the hook patterns, sentence rhythm, and formatting of your sample posts.
LinkedIn and X native
Knows the optimal length, structure, and formatting for each platform — not the same draft cross-posted.
Length control
Short, medium, long, or thread mode. Outputs fit the target without manual trimming.
Angle prompts
Set a specific angle (contrarian, data-driven, personal story) and the AI builds around it.
Regenerate per section
Don't like the hook? Regenerate just the opener while keeping the body intact.
Forbidden-phrase filter
Built-in filter removes ~30 AI tell phrases ("dive into", "let's unpack", "game-changer") before drafts reach you.
Who it's for
B2B founders building in public
Voice consistency matters because you are the brand — no team voice to fall back on.
Solopreneurs and consultants
Posting consistency is the bottleneck. Voice-aware drafts cut writing time from 30 minutes to 5.
Content marketers
Need volume across multiple voices (founder voice, brand voice, customer voice) without sounding generic.
Frequently asked questions
How does the AI learn my voice?
You paste 3–5 of your existing posts into the Content DNA setting once. The AI extracts your hook patterns, sentence rhythm, formatting preferences, and signature phrases. Every future draft references this profile.
How is this different from ChatGPT?
ChatGPT generates from a generic instruction prompt every time. Propelr generates from your specific voice profile, the platform you're writing for, and the length you specified. Less prompting, more consistent output.
Will the AI publish posts automatically?
No. The AI generates drafts. You edit and either post immediately or schedule for later. Nothing leaves your hands without your explicit action.
What if the draft is wrong?
Regenerate the whole thing, regenerate just the hook, or edit inline. Drafts cost credits regardless, so we focus on getting the first generation high enough quality that you only need light edits.
Does it work in languages other than English?
The underlying models handle many languages, but voice training works best in English right now. Non-English voice training is on the roadmap.
