Before you choose
Check the starting cost
Look for a free plan if you want to begin without a subscription. GravityWrite lists a free plan with paid access from $49 per month, while Optimate lists paid access from £29 per month and a 14-day trial.
Trial terms vary. PostNext lists a 7-day trial, and Ocoya lists paid access from $29 per month with a 7-day trial.
Match the tools to your devices
The comparison records web, API, iOS, Android, browser extension and macOS support. Check the platform field against the way you plan to create or connect captions.
An API option can suit a workflow that sends caption requests from another service. A web option can fit browser-based work.
Review caption controls
Compare hashtag generation, brand voice controls, bulk generation and caption templates. These fields show how a tool can shape captions and handle repeated work.
If consistent wording matters, look for brand voice controls and templates. If you need batches of posts, check bulk generation.
Check language coverage
Language count is a comparison field. Check it when you write for audiences using more than one language, and confirm that the count fits your publishing needs.
