Frequently Asked Questions

Is letsflw free to use?

Yes. All the local tools are free, require no sign-up, and have no usage limits. The AI tools are free to try with a free account, which includes a daily taste. For higher limits, see our Pro and Expert plans.

Do I need an account?

No account is needed for the free tools such as the word counter, grammar checker, and readability checker. You only need a free account to use the AI-powered tools.

How much do the paid plans cost?

Pro is $8.99/month (or $6.25/month billed annually) and Expert is $14.99/month (or $10.42/month billed annually). Both are launch prices. See the full breakdown on our pricing page.

What's the difference between Free, Pro, and Expert?

Free gives you all local tools unlimited plus a daily taste of the AI tools. Pro unlocks every AI tool with a higher daily limit and longer outputs. Expert adds the highest limits, the longest outputs, and upcoming automations and bulk generation. The pricing page has a full comparison.

Is my text private?

The free tools process your text to produce a result and do not store it. For AI tools, your text is sent to the AI model to generate the output. We do not sell your data. See our privacy policy for details.

What is the difference between the free Grammar tools and the AI Fix Grammar tool?

The free grammar tools catch clear spelling and punctuation errors quickly. The AI Fix Grammar tool understands context and handles deeper, more nuanced grammar corrections.

Can letsflw detect AI-written text?

No. Our AI-Likeness tool is an experimental stylistic estimate only and is not reliable AI detection. No tool can reliably detect AI writing, and it should never be used to judge or accuse anyone.
