me 👋

Hi, I'm Alexandro 👋

I left my Software Engineer role at Amazon to build tools that solve real problems, the kind big companies ignore because they read spreadsheets instead of using their own products.

I was spending over an hour daily just scheduling 2 shorts across 3 platforms: logging in, reformatting, uploading one by one. That felt broken. So I built PublishQPublishQ . Now I create 4 shorts in 3 minutes and schedule them to 4 platforms in under 30 seconds.

PublishQ is bootstrapped. No investors, no vanity metrics. I build what actually helps you, because I use it every day myself.

Thank you,

Alexandro

Cross-Platform PostingWrite once and publish to every account you select at the same time, instead of opening each app in turn.
Included
Customize Content per PlatformChange the text or the media for individual accounts inside the same composer — a longer version for LinkedIn, a shorter one for X — without leaving and creating a second post.
Included
Platform-Specific SettingsSet each network’s own publishing options in the composer: YouTube title, privacy, category, tags, playlist and made-for-kids; TikTok privacy level and comment, duet and stitch toggles; Instagram reel or story, share-to-feed and trial reels; plus the equivalents for Facebook, Threads, LinkedIn, X and Bluesky.
Included
Edit a Scheduled Post or DraftChange the text, the media, the accounts or the time on anything that has not gone out yet, instead of deleting it and starting again.
Included
Duplicate a PostReuse a post you already made — all of it, or just its text, just its media, or just its accounts — rather than rewriting it.
Included
Posts per month*How many posts you can schedule or publish. The allowance covers a month from your start date and then resets. Scheduled and published posts both count, and one post counts once however many accounts it goes to. Deleting a scheduled post frees its slot.Unlimited plans are subject to each network’s own daily posting limits, which we enforce to prevent spam and abuse.
Unlimited
DraftsPosts you can save without scheduling, held at once. Publish, schedule or delete one to free a slot.
Unlimited

Included
Posting Activity GraphA year of your posting at a glance, one square per day, with your current and longest posting streak — so you can see the gaps instead of guessing whether you have been consistent.
Included
Posts You Made ElsewherePosts published straight from the network are pulled in and sit alongside the ones you scheduled here, so your calendar and your numbers cover everything that account has done, not only what went through us.

Dark ModeThe whole app in light or dark, or following whatever your system is set to.
Included
Time ZonePick your time zone once. Every post time, the calendar and every chart are read in it, so a schedule means what you think it means wherever you are.
Included
Live UpdatesThe dashboard keeps itself current. A post going out, an upload finishing or a video rendering shows up the moment it happens, in every tab you have open, with nothing to refresh. The same goes for your AI agent: a draft it writes, a post it schedules or publishes and any change it makes through the API, CLI or MCP server appear in your browser as it happens.
Included
Draft RecoveryClose the composer, or the whole tab, and the post you had started is waiting for you when you come back. Nothing to save first, and no window you have to leave open.
