Strengths and limits
WaveSpeedAI
Strengths
- No subscription: The pricing page and docs describe usage-based billing from prepaid credits, with no monthly fee or commitment.
- Prices readable before you sign up: The pricing page lists starting prices per image and per second of video for named models and per 1M tokens for language models without an account.
- Automatic refunds for failures: The refund policy credits back failed requests, system errors and system timeouts, and says credits never expire.
Limits to plan around
- Free trial is only $1: The trial credit is $1 for eligible accounts on supported models; it is not a free plan, and eligibility is not guaranteed.
- New accounts are heavily limited: Bronze allows 5 predictions a minute and 2 concurrent tasks, and the next level needs a top-up whose minimum is not published.
- Generated files expire in 7 days: The Data Retention Policy says media files are temporary and generally expire within 7 days, so outputs must be downloaded.
PromptHero
Strengths
- Free account to start: The pricing page offers a free plan with limited daily generations, and the sign-in page says to start with a free account.
- Credits that do not expire: Credit packs of $59 for 1,000 and $99 for 2,000 roll over and accumulate, and can be bought without a subscription.
- Failed generations refunded: The FAQ says credits are returned when a generation fails.
Limits to plan around
- Monthly prices not visible: The pricing page opened on its yearly view, so monthly-billing amounts and the per-generation credit cost could not be read.
- Broad content licence: The FAQ terms give PromptHero a perpetual licence to display, sell and make derivatives from contributions, including on other platforms.
- Public unless you subscribe: Free and credit-pack generations are public, and public prompts and images are kept indefinitely.

Comparing tools from different categories is fine, and often useful — a writing assistant and a research tool solve different halves of the same job. The table will show you exactly where they diverge.
Questions about comparing tools
How does the comparison work?
Add two tools to the comparison tray from any tool card, then open this page. The table pulls each tool's verified plan details, platforms, strengths and limits from its profile, so both columns carry the same kind of evidence, with a separate source-check date for each tool.
Do you declare a winner?
No. The table sets two tools against each other on documented facts, not on a score. Which one wins depends on your task, your budget and your usage volume — three things we cannot see from here.
Why are some cells empty or marked unverified?
Because we could not confirm that detail on the vendor's own pages. Rather than filling the gap with a figure from elsewhere, we mark it and say why on the tool's profile.
Can I compare more than two tools?
Not at once. Two columns keep the differences readable and force a real decision. Remove either selected tool to replace it, or clear both to start a new pair.
Every figure in the table above comes from the linked profile, where the source and the verification date are listed. Browse all tools or read the editorial policy.
