Frequently asked questions
Are these tools really free?
Yes. The browser tools (formatters, counters, previews, calculators, image tools) have no limits and no account. The AI generators allow ten generations a day without signing up, and are unlimited inside Social by InstantDM.
Is anything I type or upload stored?
No. Browser tools never send your text or images anywhere. AI tools send your brief to generate the result and do not save it.
Which platforms are covered?
Instagram, TikTok, LinkedIn, X (Twitter), Facebook, YouTube, Threads, Bluesky, Pinterest, Discord, Telegram, Reddit, WhatsApp, Snapchat, Twitch and Mastodon, with the limits and sizes each one publishes.
Can I schedule posts from a tool?
Every tool has a "Schedule" link that opens the Social by InstantDM composer with your text prefilled, so the formatted caption or generated post goes straight onto the calendar.
The tools are free. So is the scheduler.
Schedule to Instagram, Facebook, X, LinkedIn, TikTok, Pinterest, Threads and YouTube from one calendar, with AI captions, previews, approvals and an API for agents. $0 today, cancel anytime.
