Turn a campaign brief, announcement or content idea into a caption shaped for the platform, audience, tone and outcome you specify.
Describe what the content needs to communicate, then set the audience, tone and goal. Spira returns a primary draft, up to three alternatives and practical notes shaped for this specific social format. Generation uses credits and requires sign-in.
Provide the topic, offer, source material, key points and any constraints the draft must follow.
Add the context that should shape the wording, structure and call to action for the selected platform format.
Review the strongest draft, compare genuinely different alternatives and copy the version you want to edit or publish.
Simple tools, clear results, no unnecessary steps
Keep product facts, key points and required wording grounded in the information you provide.

Each tool is prompted for the conventions of its format, from hook-first short scripts to skimmable LinkedIn posts.
Generate up to three distinct options instead of receiving the same draft with minor word changes.
The generator is instructed to use facts present in your brief and clearly label assumptions or recommendations.
A useful caption for LinkedIn, TikTok or Instagram follows different expectations for length, voice and calls to action.
