積分怎麼用、免費能試到哪、升級後解鎖什麼，一次說清楚。
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 上的一切都以積分計費。訂閱會在每個計費週期為你補充積分；若不想長期訂閱，一次性積分包能提供同樣的積分且不會週期性扣款。兩者共用同一個積分餘額，因此你可以訂閱、在截稿前用積分包臨時加值，或兩者並用。
論文解讀卡把任意論文 PDF 變成一頁式視覺化摘要卡，適合組會報告、Journal Club 與文獻筆記。它是訂閱會員權益：訂閱用戶每月享有 30 張額度（不消耗點數），免費帳戶含 1 張體驗卡。點數包不包含此功能——如果你每週都讀文獻，訂閱更划算。
每次生成、編輯與重新生成都會消耗少量積分——從 PDF 開始會比從文字開始略貴一些，因為 AI 需要讀取並梳理你的整篇論文。期刊封面與科研海報共用同一餘額。上方的方案表列出了每個方案包含的積分數，你可以依自己的發表頻率挑選方案。
可以。每個新帳號都會獲得免費積分——足夠你用自己的論文生成、編輯並預覽一張真實的圖文摘要，先判斷品質再決定是否付費。免費下載會帶有小浮水印；任意一次付費即可去除。
付費方案——或任意一次性積分包——都會去除下載檔案上的浮水印，並解鎖 SVG 向量匯出（可精準符合期刊的尺寸與 DPI 要求），同時提供你反覆打磨所需的更多積分。生成、編輯與預覽對所有人開放；付費買的是乾淨、可發表等級的成品。
可以，而且這正是核心流程。每一次生成的結果都完全可編輯：調整版面、標籤、術語、圖示、配色與文案，或重新生成局部，直到畫面與你的結果一致。多數研究人員都是在草稿上反覆迭代得到可投稿的版本，而非一次到位。
GAAbstract 生成的是可直接用於投稿的圖文摘要——版面乾淨、標註準確、匯出格式為期刊所接受。科學內容與每一個字都由你完全掌控，可精修任意細節，直到畫面精確呈現你的結果。支援匯出高解析度點陣圖或可縮放向量圖，符合期刊的尺寸與 DPI 要求。
可以。把圖匯出為 PNG、JPG 或 TIFF（付費方案還可匯出 SVG 向量），直接放進 Word、LaTeX、PowerPoint 或期刊投稿系統即可，無需二次調整。圖像以 300 DPI、期刊標準的單欄或雙欄寬度算圖，拿到即是印刷解析度，且正好是期刊要求的尺寸。
是的。你生成的圖文摘要、封面與海報都歸你所有，可用於論文、演講、海報以及社群媒體——作品生成後不再收取任何按次或授權費用。
訂閱積分在每個計費週期刷新，宜在當期內用完。一次性積分包自購買起一年內有效——更適合集中發表、而非每月都發表的研究人員。
有——GAAbstract 專為研究人員打造，我們為通過驗證的學生與教職員工提供教育優惠（目前學生享 40% 折扣、教師享 20% 折扣）。在定價頁用你的學術身分提交申請，通過驗證後折扣即自動套用到你的方案。
可以隨時在帳戶設定中升級、降級或取消——變更立即生效；若取消，方案會保留到目前計費週期結束。自購買起 7 天內，若已使用的積分不超過 10%，可申請退款（可能收取最高 6% 的手續費）。詳情請見我們的退款政策。
