Sometimes you can reach a prompt box. In our current tests, that has not yet been the same as getting a saved, auditable slide deck. The clearest no-login candidates, SlideGen and Slidesgo, exposed public prompt surfaces and strong free/no-login or free/PPTX claims, but our scheduled browser runs did not produce a deck, outline, editor, or export.
The public evidence so far is useful, but it is setup-friction evidence, not deck-quality evidence. SlideGen and Slidesgo reached the strongest no-login paths; they still failed to produce visible HarborFit deck output in our captured runs. Other presentation tools reached signup, password-handling, human-verification, security-filter, credit-card, or OAuth boundaries before output.
This does not prove those tools are bad. It means a reader should not rely on “free AI PowerPoint generator” or “no signup” marketing copy until they have verified a generated deck, export format, watermark behavior, and privacy controls for their own use case.
Public route or claim: Homepage claimed “No login · No watermark · 100% free” and “Prompt to PPT in seconds.”
Observed result: We reached and filled the public composer, but click and Enter submissions did not produce a visible deck, outline, editor, download link, loading state, or error after waiting. Sign-in controls appeared in post-submit captures.
Status: Setup friction only — not scored
Public route or claim: Prompt entry, slide-count controls, free/PPTX marketing copy, and a downloadable-PPTX workflow were reachable without completing an account first.
Observed result: A June 26 retest reached and filled a public textarea, but automated submit attempts still left the page on the marketing/form surface with no generated deck, editor, outline, export, or account-free output after 45 seconds. Earlier testing reached a 403 security-filter page after theme selection.
Status: Setup friction only — not scored
Public route or claim: Wizard accepted the prompt and then promised a free deck with no credit card required.
Observed result: Generation moved to a signup gate with Google and email/password options. We stopped before password submission because the scheduled-browser route was not safe for vault-first credential handling.
Status: Signup-gate evidence only — not scored
Public route or claim: Both had free/no-card or free-workspace language near the presentation workflow.
Observed result: Both reached human-verification/security gates in the scheduled browser before any generated deck or export evidence existed.
Status: Signup/security friction only — not scored
Our fixture is a fictional HarborFit Studio strategy memo for an 8-slide client deck. It lets us check slide structure, exportability, and hallucination risk without exposing real client data.
If a tool gives you a working deck without login, save the raw output before editing, export both PDF/PPTX if possible, and compare every slide against your source notes. If the tool asks you to sign up before output, stalls after submission, or only shows marketing/sign-in UI, record that as setup friction rather than proof of deck quality.
