SocialAgent10 free social media tools
A post image generator, plus generators, counters and calculators for the small jobs that interrupt writing. No login, no API key, and nothing you type leaves your browser — every one of these runs locally on this page.
Text post image generator
A free quote card generator and text post generator for Instagram. Turn quotes or short posts into images with your name and photo. No login or watermark.
- Light, dim and dark cards — the three themes people actually screenshot
- Square, portrait, story or card-only, all exported at full resolution
- Your profile picture stays on your machine; nothing is uploaded

Why these are free, and what they are not
These tools are deterministic: they combine what you type with structures, limits and formulas that do not need a language model. That is why they are instant, free and private — and also why they cannot write in your brand voice or know anything about your business.
That part is what SocialAgent does, using your OpenAI, Anthropic or Google AI key: drafts written from your brand profile and your own sources, a version per platform, and a review step before anything publishes.
