X · Launch day
We shipped a thing. If you're a founder who hates writing X posts more than you hate cold email, that's the gap we built into. 3 minutes, your URL, four channels of copy.
Open Boostlane An X post writer built for founders, not for content marketers.
Boostlane turns your product URL into a sharp, 280-character X post with a real hook, a real proof point, and a clean break before the body. No hashtags, no em dashes, no 'introducing' openers, no threads pretending to be insight.
What you get
Trained on what a launch post actually needs
Every X post leads with a hook on line one, a blank line, then a body. The model is told to match the post's archetype this run: stat hit, contrarian reframe, anecdote, hot take, rotated so two runs on the same product produce structurally different posts.
Your voice, not a marketing AI's
Connect your X handle (Pro) and Boostlane mirrors your cadence and vocabulary. Or fill out a 75-second brand intake and it locks onto your founder story, allowed CTAs, and the things you never say.
Diversity memory across runs
Past opener patterns, proof points, CTAs, and themes get blocked next run so your last post doesn't anchor your next one. Generate ten X posts on the same product and the openers and proofs rotate instead of repeating.
Example output
X · Day 2 silence
Built a product. Posted once. Crickets. The distribution gap isn't 'content saturation'. It's the day-2 silence. Same gap we kept walking into until we built a tool to close it for ourselves.
X · Contrarian hook
Posting more isn't your problem. Posting nothing because the blank tweet box is a cliff is your problem. We wrote the runway.
FAQ
How is this different from a generic AI tweet generator?
Generic generators take a prompt and output one shape, usually a thread or a list. Boostlane reads your product page, builds a brand card (allowed CTAs, founder story, never-say list), picks a different post archetype each run, and bans phrases your last run already used. Same product brief produces structurally different X posts run-over-run.
Does it write threads?
No. By design. Boostlane writes one standalone X post per run, max 280 characters, hook + blank line + body. Threads are a separate distribution motion; we wanted the single-post discipline to be sharp first.
Can it match my writing voice?
Yes. On Pro plans, connect your X handle and Boostlane extracts a style profile: cadence, vocabulary, structural patterns, that the writer prompt has to match. On Free and Starter, the brand intake's founder story carries the voice signal.
What does it cost?
Free to try. Paid plans start at $19/month for Starter, $29/month for Pro (voice mirror unlocks here), $79/month for Scale. One credit per channel per run.
Will my X posts look like every other Boostlane user's?
No. The writer pulls from your specific BrandCard, your specific user notes for that post, and your live distribution intel for your niche. Two founders on different products will not share openers, proof points, or angles.
Does it use hashtags or em dashes?
Never. Both are blocked as hard rules in the writer prompt: em dashes get replaced with commas or periods, hashtags get stripped entirely. The output reads like a founder wrote it, not a content marketer.
