Is SmoothLines free to use?
You get 15 generations for free and no card is required. That is a one-time allowance rather than a monthly one, so it does not refill. After that, Starter is €3.99 a month for 750 generations and Pro is €9.99 a month for 1,850, both resetting on the 1st of each month.
Why not just use ChatGPT?
You can, and ChatGPT can read a screenshot too. The difference is the work. There you write the prompt, read a long answer and rewrite the part you want. Here you upload a screenshot and get three short lines written the way you text, and one tap makes them funnier, shorter or bolder. Your screenshots are never saved on our servers or used to train AI.
Which dating apps does it work with?
Any app you can screenshot, including Tinder, Bumble and Hinge. SmoothLines reads the image instead of connecting to the app, so there is no account to link and no dating-app password to hand over.
What happens to the screenshots I upload?
They are sent to OpenAI to write your lines and are never saved by us: they exist only in memory while the generation runs. Under OpenAI’s API data policy they are not used to train its models and may be kept for up to 30 days for abuse monitoring. The lines themselves stay in your history until you delete them.
Can it write replies, or only opening lines?
Both. Screenshot a profile and you get openers; screenshot a conversation that is already going and you get replies that follow what has been said so far.
Do I need an account?
Yes, generating requires one. You can sign in with Google or with a magic link sent to your email address, so there is no password to choose or remember.
How many writing styles are there?
40 styles across 5 categories — general tones plus voices modelled on dating coaches, philosophers, writers and motivational speakers. Every style is available on every plan, including the free one.
How do I cancel a subscription?
Plans are monthly and you can cancel whenever you like from the Stripe billing portal, which you open from your profile page. Cancelling stops any future charges.
How many screenshots can I upload at once?
Up to 2 per generation, 4.2 MB each, in any common image format — JPEG, PNG, WebP, GIF or HEIC straight off your phone.
