积分怎么用、免费能试到哪、升级后解锁什么，一次说清。
Everything on GAAbstract runs on credits. A subscription refills your credits every billing cycle; if you'd rather not commit, one-time credit packages give you the same credits with no recurring charge. Both feed a single balance, so you can subscribe, top up with a package before a deadline, or do both.
Paper Explainer turns any paper PDF into a one-page visual summary card — great for journal clubs, lab meetings, and reading notes. It's a membership perk: subscribers get 30 cards every month (no credits needed), and free accounts include 1 trial card. Credit packs don't include Paper Explainer — if you read papers every week, a subscription is the way to go.
Each generation, edit, and regeneration uses a small number of credits — starting from a PDF costs a little more than from text, since the AI reads and structures your whole paper. Journal covers and scientific posters draw from the same balance, and the plan table above shows how many credits each plan includes, so you can match a plan to how often you publish.
Yes. Every new account gets free credits — enough to generate, edit, and preview a real graphical abstract from your own paper, so you can judge the quality before spending a cent. Free downloads carry a small watermark; any paid purchase removes it.
A paid plan — or any one-time credit package — removes the watermark from your downloads and unlocks vector SVG export (ideal for meeting a journal's exact size and DPI requirements), plus the larger credit balance you need to iterate freely. Generating, editing, and previewing are open to everyone; paying is about clean, publication-grade output.
Yes, and that's the whole workflow. Every generation stays fully editable: change the layout, labels, terminology, icons, colors, and wording, or regenerate parts until the figure matches your result. Most researchers reach a submission-ready figure by iterating on a draft, not by nailing it on the first try.
GAAbstract produces publication-ready graphical abstracts you can take straight into your journal submission — clean layouts, accurate labels, and export formats journals accept. You stay in full control of the science and every word, refining any detail until the figure represents your result exactly. Export as high-resolution raster or scalable vector to meet your journal's size and DPI requirements.
Yes. Download your figure as PNG, JPG, or TIFF — or SVG vector on a paid plan — and place it directly into Word, LaTeX, PowerPoint, or a journal's submission portal, with no reformatting needed. Figures render at 300 DPI at standard single- or double-column widths, so they arrive at print resolution and the exact size journals expect.
Yes. The graphical abstracts, covers, and posters you generate are yours to use in manuscripts, talks, posters, and on social media — with no per-use or licensing fees once they're created.
Subscription credits refresh each billing cycle and are meant to be used within it. One-time credit packages stay valid for a full year from purchase — a better fit for researchers who publish in bursts rather than every month.
Yes — GAAbstract is built for researchers, so we offer education pricing for verified students and academic staff (currently 40% off for students and 20% for teachers). Apply from the pricing page with your academic credentials, and the discount applies to your plan once verified.
Upgrade, downgrade, or cancel anytime from your account settings — changes take effect immediately, and if you cancel, your plan stays active through the end of the billing period. Refunds are available within 7 days of purchase if you've used no more than 10% of your credits (a processing fee of up to 6% may apply). See our Refund Policy for details.
GAAbstract 上的一切都以积分计费。订阅会在每个计费周期为你补充积分；如果不想长期订阅，一次性积分包能提供同样的积分且不产生周期性扣费。两者共用同一个积分余额，所以你可以订阅、在截稿前用积分包临时充值，或两者兼用。
论文解读卡把任意论文 PDF 变成一页式可视化摘要卡，适合组会讲文献、Journal Club 和文献笔记。它是订阅会员权益：订阅用户每月享有 30 张额度（不消耗积分），免费账户含 1 张体验卡。积分包不包含此功能——如果你每周都读文献，订阅更划算。
每次生成、编辑和重新生成都会消耗少量积分——从 PDF 开始会比从文本开始略贵一些，因为 AI 需要读取并梳理你的整篇论文。期刊封面和科研海报共用同一余额。上方的套餐表列出了每个方案包含的积分数，你可以按自己的发表频率来挑选方案。
可以。每个新账号都会获得免费积分——足够你用自己的论文生成、编辑并预览一张真实的图文摘要，先判断质量再决定是否付费。免费下载会带有小水印；任意一次付费即可去除。
付费方案——或任意一次性积分包——都会去除下载文件上的水印，并解锁 SVG 矢量导出（可精准满足期刊的尺寸与 DPI 要求），同时提供你反复打磨所需的更多积分。生成、编辑和预览对所有人开放；付费买的是干净、可发表级别的成品。
能，而且这正是核心流程。每一次生成的结果都完全可编辑：调整版式、标签、术语、图标、配色和文案，或重新生成局部，直到画面与你的结果一致。多数科研人员都是在草稿上反复迭代得到可投稿的版本，而不是一次成型。
GAAbstract 生成的是可直接用于投稿的图文摘要——版式干净、标注准确、导出格式为期刊所接受。科学内容和每一个字都由你完全掌控，可精修任意细节，直到画面精确呈现你的结果。支持导出高分辨率位图或可缩放矢量图，满足期刊的尺寸与 DPI 要求。
可以。把图导出为 PNG、JPG 或 TIFF（付费方案还可导出 SVG 矢量），直接放进 Word、LaTeX、PowerPoint 或期刊投稿系统即可，无需二次调整。图像按 300 DPI、期刊标准的单栏或双栏宽度渲染，拿到即是印刷分辨率，且正好是期刊要求的尺寸。
是的。你生成的图文摘要、封面和海报都归你所有，可用于论文、演讲、海报以及社交媒体——作品生成后不再收取任何按次或授权费用。
订阅积分在每个计费周期刷新，宜在当期内用完。一次性积分包自购买起一年内有效——更适合集中发表、而非每月都发的科研人员。
有——GAAbstract 专为科研人员打造，我们为经过验证的学生和教职员工提供教育优惠（目前学生享 40% 折扣、教师享 20% 折扣）。在定价页用你的学术身份提交申请，通过验证后折扣即自动应用到你的方案。
可以随时在账户设置中升级、降级或取消——更改立即生效；若取消，方案会保留到当前计费周期结束。自购买起 7 天内，若已使用的积分不超过 10%，可申请退款（可能收取最高 6% 的手续费）。详情请见我们的退款政策。
