# SmoothLines > AI pickup line generator for Tinder, Bumble & Hinge. Upload a screenshot and get personalized openers in seconds. Free to try. SmoothLines is a web app that writes dating-app openers and replies. You upload a screenshot of a match's profile or an ongoing chat from Tinder, Bumble, Hinge or a similar app, pick one of 40 writing styles across 5 categories, and the app returns suggested messages you can copy. Generated lines are saved to your history, where they can be searched, bookmarked or deleted. ## Using it - An account is required to generate. Sign in with Google or with an emailed magic link — no password. - Up to 2 screenshots per generation, 4.2 MB per image (JPEG, PNG, WebP, GIF, HEIC and other common formats). - Generation runs as a background task: the app returns a task id and polls it until the lines are ready. - Uploaded screenshots are deleted from storage once a generation finishes, whether it succeeded or failed. ## Pricing - Free — €0. 15 generations in total (one-off allowance, not a monthly reset).

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. ### 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 used only to generate your lines, then deleted from our storage as soon as the generation finishes — whether it succeeded or failed. 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. ## Core pages - [SmoothLines - Generate Pickup Lines for Tinder & Bumble](https://smoothlines.app/): AI pickup line generator for Tinder, Bumble & Hinge.
