Deliver a 12-slide editable PPTX within US$15 for the month

Gamma Free offers a no-subscription-cost route worth verifying, but the final twelve-slide file editability and layout still need inspection. Genspark current monthly export plan is over budget, as is Manus documented native PowerPoint route. No completed file has passed a hands-on test here.

The task

Use monthly billing of at most US$15 to turn public Chinese materials into twelve slides, downloaded as PPTX so colleagues can keep editing in PowerPoint. PDFs, images, web links and editing only inside the original product are not enough. One-shot generation of twelve slides and removal of branding are not requirements.

Official sources checked 23 September 2026. Budgets assume a US personal account, USD before tax and monthly billing without annual prepayment. Region, eligibility and checkout prices can differ, and nothing here is a generation, quality or workload test.

Candidates

Meets the documented conditions is not the same as a completed task: it means the conditions listed in the official pages are satisfied, and the limits below still apply.

Gamma Free

Unconfirmed; not recommended yet

This month: US$0 fits the budget. The Plus monthly checkout price was not verified, so no older price is substituted here.

Unconfirmed, but worth verifying the free route first: one prompt generates up to ten slides and two can be added manually, PPTX export is supported with Gamma branding, and free AI credits do not renew automatically. Editable native tables do not guarantee every chart, visual object or Chinese layout.

  • If the deliverable must be twelve slides in one generation, unbranded, or with more retries, the real monthly price and allowance have to be established first, and an annual equivalent cannot be used to fit US$15.

Genspark Plus

Does not meet this task

This month: US$24.99 a month, where US$239.99 is the annual total: over US$15.

Does not meet the budget. File export requires payment, and complex tables or charts may become images or shapes; editing inside the product does not prove native PowerPoint editability.

  • Support for PPTX is not the same as all elements staying editable and faithful.

Manus native PowerPoint Beta

Does not meet this task

This month: Pro starts at US$20 a month, and the Free Agent plan only includes 1.6 Lite: over the budget.

The native route exceeds the budget: the mode requires 1.6 or Max, and Free exclusion is inferred from two official documents rather than an account test. The older Standard conversion route is different, and its free deliverability remains unconfirmed.

  • A conversion route is not the same as native PowerPoint generation.

A concrete free attempt

Check the credits remaining on your Gamma account, prepare a twelve-slide outline, generate up to ten slides and add two manually. Export the PPTX, edit text in PowerPoint, save and reopen it, and if the deck contains a table, edit a table cell as well. If the task depends on a chart whose data must change, test that too. Flattened critical content, uneditable key elements, broken fonts or overflow mean the file does not pass.

Cost boundary

Manual page additions and cleanup are allowed, and repeated generation is not guaranteed to be free. The Gamma route is a workflow to verify rather than a completed PPTX delivery, and Genspark or Manus cannot be made to fit by annual equivalents or by guessing an unknown free path.
