ProPostly
Chrome extension that writes LinkedIn posts, DMs, replies, headlines, and lead lists inside LinkedIn.
Tagline
LinkedIn AI that lives in your browser
Your all-in-one LinkedIn workflow, right inside the page
Cheaper than a ghostwriter. Faster than ChatGPT tabs.
Stop blank-page syndrome. Start posting and prospecting.
The all-in-one LinkedIn writing layer that lives inside your browser.
This is the cleanest category-defining frame because the product is not a standalone AI writer; it is an in-context extension across posts, DMs, comments, headlines, and lead search.
The cheaper, faster replacement for hiring a LinkedIn ghostwriter.
The page explicitly compares ProPostly to $500–2,000/month ghostwriters and positions ProPostly at $9/month, which is a strong value wedge for solo operators and small teams.
Stop wasting time on generic outreach and blank-post syndrome.
The landing page repeats pain language around blank pages, generic DMs, and posting into silence; that makes a direct pain-killer angle stronger than a vague AI efficiency story.
Primary user
B2B founder or marketer who posts on LinkedIn weekly and uses outbound DMs to drive leads
ICP #1
Solo founder of a B2B SaaS startup doing founder-led growth
Pain
They know LinkedIn can drive inbound deals, but every post takes forever and their DMs sound canned, so they post inconsistently.
Why this solves
ProPostly removes the blank-page bottleneck with instant post drafts, personalized DMs, and headline rewrites directly on LinkedIn, which matches the exact workflow of a founder trying to stay visible while selling.
ICP #2
Agency owner or B2B consultant who sells via LinkedIn content and relationship-building
Pain
They need to produce high-volume content and personalized outreach for multiple clients or offers, but manual personalization and rewriting burn hours every week.
Why this solves
The extension combines content generation and lead qualification in one place, and the CSV export plus per-profile DM drafts make it practical for repeatable outbound work.
ICP #3
SDR or sales manager at a small B2B team prospecting in LinkedIn every day
Pain
They waste time toggling between LinkedIn, notes, and AI tools just to write one message per prospect, then still have to hunt for relevant leads.
Why this solves
Deep Lead Search plus profile-aware DM generation cuts the workflow down to a few clicks and gives them outreach drafts tied to the actual prospect profile instead of generic templates.
Strengths
- +The product is shown in-context inside a real LinkedIn UI, which makes the value instantly legible.
- +The page does a good job bundling five adjacent use cases into one workflow instead of pitching isolated features.
- +The pricing contrast against ghostwriters is sharp and memorable, especially the "$9/month" wedge.
Weaknesses
- −The page tries to sell too many jobs-to-be-done at once; post writing, DMs, comment replies, headline optimization, and lead gen all compete for attention.
- −The claims are sometimes too broad or too cute, like "10× better reply rates" and "same output a ghostwriter charges $800+ for," which may feel unproven.
- −The lead search feature is interesting but under-explained; I can see Hot/Warm/Cold and CSV export, but not the exact filtering logic or data source boundaries.
- −The brand story is generic in places: it says AI-powered content for LinkedIn, but the sharper truth is browser-native LinkedIn workflow automation for content and outreach.
- −The roadmap to Instagram and Reddit is distracting on the same page; it weakens the LinkedIn-only focus and adds future promises before the core offer is fully nailed.
Fix these
- Pick one hero wedge for the homepage above the fold: either LinkedIn content creation or LinkedIn outbound, not both equally.
- Add one concrete before/after workflow graphic showing a real user going from profile or prompt to post/DM/lead list in under 30 seconds.
- Replace vague performance claims with proof blocks: examples, screenshots, or anonymized metrics from actual users.
- Move Instagram and Reddit roadmap content lower or off-page so the LinkedIn message stays dominant.
- Create separate landing-page sections or pages for the three strongest segments: founders, SDRs, and consultants, each with specific messaging and examples.

Headline
Write LinkedIn faster, inside LinkedIn
Posts, DMs, replies, headlines, and lead search in one Chrome extension.
Turn any prompt into LinkedIn drafts
Start with a topic, a profile, or a rough idea and get three ready-to-edit drafts in seconds. No blank page, no tab switching, no copy-paste loop.
Write DMs that actually fit the profile
ProPostly uses visible LinkedIn context like name, headline, about, and recent posts to draft a more personal message. It feels tailored without taking five minutes per prospect.
Find leads and draft outreach in one flow
Deep Lead Search helps you spot matching profiles, label them Hot, Warm, or Cold, and export them to CSV. Each lead comes with a DM prompt so outreach starts from something useful.
Skip the tools you don't need
You don't need a ghostwriter, a separate AI app, and a spreadsheet just to stay active on LinkedIn. ProPostly keeps the whole workflow in the browser where you already work.
FAQ
Does ProPostly work inside LinkedIn?
Yes. It's a Chrome extension that runs directly on LinkedIn pages, so you can generate content without leaving the site.
Do you store my LinkedIn password?
No. ProPostly works through the browser and does not store your LinkedIn password.
What can it generate?
It writes LinkedIn posts, personalized DMs, reply drafts, headline rewrites, and lead outreach prompts.
How is this different from ChatGPT?
ChatGPT gives you text in a separate tab. ProPostly lives inside LinkedIn and uses the profile or page context you're already looking at.
Who is this for?
Founders, marketers, SDRs, consultants, and anyone who uses LinkedIn for posting or outbound and wants a faster workflow.
That tab-switching workflow is why posting feels like a chore. ProPostly writes LinkedIn posts, DMs, replies, and headlines right inside LinkedIn. Less copying. Less friction. More output.
Built ProPostly because founders don't need another AI tab. They need posts, DMs, replies, and lead lists inside LinkedIn itself. Chrome extension. 3 drafts per prompt. No password stored.
Open someone's LinkedIn profile. Click ProPostly. It reads the visible context and drafts a personalized DM in seconds. No generic templates. No "hope you're well" nonsense.
I wanted one thing: less context switching. So I built ProPostly to generate posts, replies, headlines, and lead lists where the work already happens. If LinkedIn is your channel, this should feel obvious.
ProPostly is $9/month. Same core jobs: posts, DMs, replies, headlines, lead search. If you're a solo founder or SDR, the math is pretty simple.
You know you should post. You know LinkedIn can drive deals. But writing from scratch every time is slow, so you skip days. ProPostly gives you 3 drafts instantly.
Posts. DMs. Comment replies. Headline rewrites. Deep Lead Search. ProPostly does the boring part so you can ship faster and prospect smarter.
Deep Lead Search finds matching LinkedIn profiles, labels them Hot/Warm/Cold, and drafts outreach for each one. It's like prospecting with fewer tabs and less guessing.
They need one tool that cuts the busywork. ProPostly replaces the post draft, the DM draft, the headline rewrite, and the lead list scramble.
The strongest wedge wasn't "AI for LinkedIn." It was: write faster inside LinkedIn, prospect faster inside LinkedIn, stop leaving the tab. Simple wins.
Angle: browser-native workflow
Most AI writing tools miss the real problem. It's not writing. It's context switching. Founders, SDRs, and consultants don't need another tab with a prompt box. They need help where the work already happens. That's why I built ProPostly. A Chrome extension that lives inside LinkedIn and helps you write: - posts from a topic - personalized DMs from a profile - reply drafts for comments - headline rewrites - lead lists with Hot / Warm / Cold labels The goal is simple: take a raw prompt or profile and turn it into something usable in seconds. No copy-paste loop. No bouncing between LinkedIn and ChatGPT. No blank page staring contest. If LinkedIn is part of your growth motion, this should feel like the missing layer. I'd love feedback on one thing: what would make this 2x more useful for daily LinkedIn work?
Angle: cheaper than ghostwriters
A good LinkedIn ghostwriter is expensive. A decent one is still expensive. And for most founders, it doesn't even solve the real bottleneck. The bottleneck is not "can someone write for me?" It's "can I get something good enough, fast enough, inside the same workflow?" That's the bet behind ProPostly. It helps you write LinkedIn posts, DMs, replies, and headlines without leaving LinkedIn. It also finds leads and drafts outreach, so the writing and prospecting happen in one place. For solo founders, small B2B teams, and consultants, the comparison is blunt: - ghostwriter: $500 to $2,000/month - ProPostly: $9/month I don't think most people need artisanal LinkedIn content. I think they need speed, consistency, and less friction. That was the product idea. Turn the browser into the writing layer. If you were paying for LinkedIn help today, would you rather pay for a human or a tool like this?
Angle: pain-killer for outbound and content
LinkedIn has two expensive problems. 1. Posting consistently is annoying. 2. Personalized outreach is slower than it should be. You know what makes both worse? Generic tools. If you write a post in one tab, then paste it into another tool, then hop back to LinkedIn to edit it, the workflow already lost. If you research a prospect, then manually rewrite a DM from scratch, you're wasting time on the wrong part. ProPostly is my attempt to remove that friction. It sits inside LinkedIn and helps you generate: - post drafts with 3 options - more aggressive "viral" rewrites - DMs based on visible profile context - comment replies - headline rewrites - Deep Lead Search with outreach drafts Not because it's fancy. Because it's practical. The product should feel like a better workflow, not another AI toy. If you're using LinkedIn weekly for content or outbound, I'd genuinely like to know: what part of the workflow is most painful today?

AI writing for LinkedIn, inside LinkedIn
Description
Chrome extension that drafts LinkedIn posts, DMs, replies, headlines, and leads right on the page. Three options per generation, Hot/Warm/Cold lead labels, and CSV export.
Maker's first comment
I built ProPostly because I kept watching the same thing happen: people would open LinkedIn with good intentions, then spend 20 minutes switching between tabs, prompts, profiles, and half-finished drafts. The actual work wasn’t hard - it was just fragmented. I wanted a tool that stayed inside the place where LinkedIn work already happens. So ProPostly generates posts, DMs, comment replies, headline rewrites, and lead lists directly in the browser, without making you copy-paste everything through ChatGPT first. The biggest win I wanted wasn’t “more AI.” It was less friction. If you’re a founder, SDR, or consultant using LinkedIn as part of your growth motion, the workflow should feel fast enough that you actually use it every day. I’d love feedback on two things: what’s the most valuable LinkedIn task to speed up, and what would make the extension feel indispensable instead of nice-to-have?
Pinned maker comment
Would love feedback on the lead search workflow, the quality of profile-based DM drafts, and whether the product should lean harder into content creation or outbound.
Meta
Still writing LinkedIn posts in another tab?
Hypothesis: founders and consultants posting weekly will convert better if the writing happens inside LinkedIn, not in a separate AI app. ProPostly drafts posts, DMs, and replies directly on the page so the workflow stays fast.
Google Search
LinkedIn post writer Chrome extension
Hypothesis: people searching for LinkedIn writing help want speed and in-context editing, not another general AI tool. ProPostly generates posts, DMs, headlines, and lead drafts inside LinkedIn in seconds.
Reddit Promoted
Built a LinkedIn tool because tab-switching is dumb.
Hypothesis: indie founders, SDRs, and agency owners care more about workflow friction than fancy AI features. ProPostly lives inside LinkedIn and turns profiles or prompts into posts, DMs, replies, and lead lists without copy-paste hell.

Cold outreach template
Hey {firstName} - noticed {context} and thought of ProPostly. It drafts LinkedIn posts, DMs, replies, and lead lists right inside LinkedIn, so you don't have to bounce between tabs. If I send a 30-second demo, would you tell me if this would save you time?
Product Hunt timing
Launch on Tuesday at 8:00 AM Pacific Time. That hits the US workday early, catches Europe late morning, and gives the product a full day of traction before the weekend without getting buried in Monday noise.
