Deliver a 12-slide editable PPTX within US$15 for the month
Gamma Free offers a no-subscription-cost route worth verifying, but the twelve-slide PPTX’s editability and layout still need inspection. Manus is also unconfirmed: its native PowerPoint Beta article names 1.6 and Max, while current membership help names 2.0 Lite for Free and 2.0 variants for Pro. Those pages do not establish whether today’s Free plan can use the native route; the documented Pro starting figure is not a US$15 route. The checked Genspark monthly export plan exceeds the cap. Notion’s startup page lists $20 per member paid annually but does not state a monthly unit; the applicable charge remains unverified. No completed file has passed a hands-on test here. Notion’s separate limited trial remains unconfirmed for this one-off task; the paid-route price does not exclude that trial.

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.
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 yetThis 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.
- Gamma’s current table limits Free to ten slides per prompt and reserves branding removal for paid plans; Plus lists up to 100 slides per prompt. If twelve slides in one generation, no branding or more retries are required, the actual monthly purchase price and allowance still need confirmation; an annual equivalent cannot be used to fit US$15.
Genspark Plus
Does not meet this taskThis 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.
- Genspark’s PPTX FAQ says complex HTML tables and charts can be converted to images or shapes and may not remain editable native PowerPoint data objects. The fidelity and editability of the actual Chinese deck still require inspection.
Manus native PowerPoint Beta
Unconfirmed; not recommended yetThis month: Current membership help lists Pro from $20 a month and Free Agent access to2.0Lite. The PowerPoint Beta article still names1.6 and Max rather than the current2.0 variants, so current Free access to native PowerPoint is unconfirmed. No verified monthly route inside the US$15 budget is established by these two pages.
The native PowerPoint Beta authors a realPPTX rather than converting the earlier web format. Its article says1.6/Max, while current membership help names2.0Lite for Free and 2.0variants for Pro. That mismatch does not establish that today’s Free tier is excluded or included. The earlier Standard conversion route remains a different capability; its complete free deliverability and current monthly entitlement were not tested.
- A conversion route is not the same as native PowerPoint generation.
Notion AI
Unconfirmed; not recommended yetThis month: The startup page lists $20 per member paid annually without stating a monthly unit; the applicable charge is unverified. Free/Plus trial responses are a separate possible route, with remaining allowance, task access and any resulting charge unverified.
Keep Notion AI unconfirmed for this one-off task. Downloadable PPTX creation is documented, but trial access to the computer workspace, enough responses and retries, twelve finished slides and PowerPoint object editability have not been established. Limited trial availability alone does not exclude the product.
- Presentation Mode presents page blocks in the web or desktop app and has neither speaker notes nor a separate presentation share link; its documentation does not establish PPTX export from this mode.
- PPTX object editability, completion of twelve slides and any fixed per-file cost were not tested, so documented file creation is not a promise that the deck stays editable.
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. Gamma is a workflow to verify rather than a completed PPTX delivery. Manus needs a current statement mapping native PowerPoint access to its Free or paid 2.0 plans before the free route can be included or excluded; the old 1.6 article alone does neither. Do not use annual equivalents to force the checked paid routes inside the budget, and do not turn an unknown free entitlement into a pass. For Notion, verify trial access, remaining responses, retries and editable PPTX completion; recurring use is not a requirement of this brief.
Where every claim comes from
Each link was opened and read on the date shown. The note describes what that page actually supports.
- Gamma - pricing ↗
The current table lists ten slides per prompt on Free and up to100 on Plus, with Gamma-branding removal on paid plans. No current numeric monthly Plus card was exposed in this read. Historical registered scope read on 2026-09-23, not rechecked in full on 2026-10-15: Free at US$0 and the Plus plan; the current monthly checkout price was not verified.
- Gamma - upgrading and page limits ↗
Free can generate up to 10 slides per prompt and add more manually; Free AI credits do not refresh. This does not guarantee enough retries or a completed12-slide deliverable.
- Gamma - exporting ↗
PPTX export is documented; real editable tables are on by default on all plans. Free-workspace PPTX exports carry Gamma branding. Other effects/fonts/objects can vary in external tools; tables do not establish every chart or Chinese layout.
- Genspark - business pricing ↗
Plus at US$24.99 monthly, with US$239.99 as the annual total.
- Genspark - AI slides export access ↗
That file export requires payment and what the in-product editor does not prove.
- Genspark - AI slides FAQ ↗
Complex HTML tables/charts may become images or shapes rather than native editable PowerPoint data objects; PPTX requires an active paid membership and export itself does not consume extra credits. Historical registered scope read on 2026-09-23, not rechecked in full on 2026-10-15: How complex tables and charts may be rendered in the PPTX.
- Manus - membership pricing ↗
The membership help read today lists Free Agent access to2.0Lite and Pro from $20/month with 2.0, 2.0Max and 2.0Lite. It no longer uses the1.6 names in the older PowerPoint article; the current cross-version entitlement was not established.
- Manus - PowerPoint slides ↗
The PowerPoint article describes a nativePPTX Beta and says availability on1.6/Max, unlike the membership page now naming2.0variants. It distinguishes native mode from the earlier web-format-to-PPTX conversion; it does not establish today’s Free 2.0Lite entitlement.
- Notion AI — files and computer workspace ↗
The computer workspace documents downloadable PPTX creation and revision. It does not establish twelve slides with editable objects on a particular complimentary allowance.
- Notion AI FAQs ↗
Business and Enterprise include AI allowances; Free and Plus have limited trial responses. Computer-workspace actions follow workspace permissions; these statements do not prove trial completion of this task.
- Notion official Business annual-price reference ↗
The startup page lists $20 per member paid annually, but does not state a monthly unit. Actual account billing and purchase region were not verified.
- Notion Presentation Mode ↗
Presentation Mode Beta presents page blocks in the web or desktop app and lacks speaker notes and a separate presentation share link. The page does not establish PPTX export from this mode.
- Notion — complimentary AI responses ↗
Free and Plus have limited complimentary AI responses. AI actions and retries consume responses; after exhaustion, continued AI use requires Business or Enterprise. These pages do not establish the allowance or file-workspace access needed for this twelve-slide task.
