Hey hunters! πŸ‘‹ I built LaunchPad because launching my own browser extensions kept eating entire days. The product was done β€” but then came the Show HN that shouldn't sound like marketing, the 280-character X post, the Chrome Web Store listing with its 132-char summary, the Reddit post that dies if it smells like an ad… Same product, fifteen dialects. LaunchPad fixes that: you write one brief, it drafts every channel in that channel's native voice β€” with real structure (HN gets Title ≀80 + Text, Play Store gets Title 30 / Short 80 / Full 4000) and real character limits enforced at generation time. The parts I'm most proud of: ⚑ Free doesn't mean crippled. Everything β€” all 42 channels, every AI engine β€” is free for your first launch. On-device AI (Chrome's Gemini Nano) costs nothing and your drafts never leave your machine. Cloud engines use YOUR OpenAI/Claude key, straight from browser to provider β€” we never see it. Pro ($9/mo) buys exactly one thing: more launches. πŸ”’ Privacy that's checkable, not promised. No analytics, no tracking pixels, keys in localStorage only. The privacy page is 5 short sections. πŸš€ Launch-day workflow. Generate all 42 (or only the undrafted), watch per-channel progress, cancel anytime keeping what's done, mark channels ready as you review β€” green means a human said so, never the machine. Don't feel like signing in just to look? Here's a finished sample launch you can poke at, no account needed: It's shipped solo, and the feedback form lands in my actual inbox. Tell me what channel you launch on that I'm missing, and it'll probably exist by next week β€” most of this product was built from user requests within hours of hearing them. Ask me anything β€” I'll be here all day. πŸ§‘β€πŸš€

Does the "free for your first launch" mean each user gets one launch total, or one launch per product they ship?

Maker

Hi Β It's one launch total per account β€” but "launch" might be bigger than you're picturing.

A launch in LaunchPad is a whole product project: your brief plus drafts across all 42 channels, unlimited regenerations, every AI engine, custom channels, the works. It's not "one post" or "one platform" β€” it's everything for one product, forever free. You can keep coming back to it, re-draft for a v2 announcement, edit prompts, whatever β€” it stays yours and stays free.

The line is: a second product needs Pro ($9/mo). So if you ship one thing a year, you may honestly never pay me β€” that's fine, that user costs me nearly nothing since the AI runs on your device or your own key. If you're shipping multiple products, that's exactly who Pro is for.

And to be upfront about the obvious workaround: yes, you could delete your launch and start a fresh one for your next product. You'd lose all the old drafts and ready-states, but nothing stops you. I'd rather have a paywall people can reason about than one that plays games.

The per-channel voice matching is genuinely impressive, especially nailing the dry, technical tone that HN readers actually respond to. Most "write for 42 platforms" tools just spin up the same generic post 42 times, so this clearly takes some real craft.

Maker

Thanks, this one means a lot β€” the HN voice went through more rewrites than any other channel.

The honest answer to how it works: there's no clever prompt-engineering trick. Every one of the 42 channels has a hand-written instruction block that came from reading actual posts on that platform and paying attention to what dies there.

HN's prompt literally says things like "no marketing fluff, no generic launch-speak" and pushes toward the flat, technically-honest register β€” because the fastest way to get buried on HN is to sound excited. The Reddit one is mostly warnings about what not to do. The AMO (Firefox Add-ons) one notes that the audience is privacy-conscious and "allergic to hype," so mentioning that your extension collects nothing is worth more than any feature bullet.

And none of it is locked in β€” every section's prompt is editable right in the editor, so if you'd rather your HN post sound a little different, you rewrite the instruction once and it drives every generation after that. Saved to your account, per channel.

πŸ’‘ Bright idea

Does LaunchPad actually learn from past launches to refine tone over time, or is each draft generated fresh from the brief without any feedback loop?

Maker

Great questionΒ , and the honest answer: no feedback loop yet β€” every draft is generated fresh from your brief plus the channel's instruction block.

Some of that is a real constraint I chose on purpose. The on-device engine means your drafts never leave your machine, and there's no server-side AI at all β€” so there's nowhere for a "learn from everyone's launches" model to live without breaking the privacy promise. I'd rather ship no learning than quiet telemetry.

But there's a version of this that fits the architecture, and your comment just moved it up the list: per-user learning that stays in your account. You already can edit any section's prompt and it drives every future generation β€” the missing piece is the tool noticing your edits. If you always strip the hashtags from your X drafts or flatten the adjectives in your HN titles, that's signal sitting right there in the diff between what was generated and what you marked ready. Feeding those observations back into your prompts β€” visibly, as suggested prompt edits you approve rather than silent drift β€” keeps the loop inspectable and keeps your data yours.

Solo-built, so the roadmap is literally comments like this one. Thanks for the sharp question.
