Decka

Decka is an AI presentation maker built around an editable freeform canvas and audience-interaction tools. It suits presenters, educators, and teams that need both polished slides and participation during a session. The main trade-off is capacity: the free tier is useful for small trials, while larger or frequent sessions require a paid plan.

Overview

Decka keeps AI-generated presentations malleable rather than treating them as finished exports. That makes it a practical choice when a first draft needs substantial visual or structural revision. Real-time co-editing, collaborator invitations, and view-only links also make it suitable for team-produced presentations.

Key features

The freeform editor lets users move, resize, restyle, replace, or remove individual objects in an AI draft. Themes, image frames, background removal, and editable advanced charts provide meaningful control over layout and visual polish. You can add YouTube or uploaded video, Lottie animations, and a dynamic agenda, so the tool supports richer presentations than a static slide sequence.

Audience participation covers polls, quizzes, Q&A, word clouds, drawings, games, and other activities. A PowerPoint add-in and Google Slides Chrome extension bring those activities into familiar presentation environments. Decka requests Google Drive access one presentation at a time through Google’s picker, using file-specific permission. Enterprise activities have no stated participant cap and are load-tested to 10,000 people, although Meeting Dodgeball is capped at 300 players per game.

Decka says contractual restrictions prevent its AI providers from training general-purpose models on prompts and uploaded media submitted for AI features. The named providers are Anthropic, Google Gemini, Groq, Cerebras, and Replicate. That is a useful safeguard for teams handling sensitive material, but organizations should still assess it against their own policies.

Pricing

Decka is freemium. Free is $0.00, billed free forever with no credit card required and no free trial. It allows 50 people per activity, two live sessions per month, 200 participants per month, 100 AI quiz questions per month, 1,000 AI credits per month, and 1 GB of media storage. Those limits fit occasional demos or small meetings, not a regular training program.

Pro is $10.00 per month on annual billing ($120 billed annually). It raises the activity limit to 150 people, removes the live-session cap, permits 200,000 people per month, and includes 2,000 AI quiz questions, 6,000 AI credits per month, and 50 GB of storage. It is the sensible tier for recurring events and high monthly reach, though the annual commitment matters.

Badass costs $16.00 per month on annual billing ($192 billed annually). It supports 300 people per activity, unlimited live sessions, 12,000 AI credits per month, and 100 GB of storage. The published limits do not include a monthly participant quota or AI-quiz allowance, so buyers should confirm those points before choosing it for sustained heavy use.

Enterprise uses custom pricing. It adds no cap on people per activity, load-tested delivery for 10,000 people in one activity, SSO/SAML, API access, custom data retention, and dedicated onboarding and priority support. It is aimed at organizations with governance and scale requirements rather than casual presenters.

Platforms

Decka is offered on the web, macOS, and Windows, with an API and browser extension. Its PowerPoint add-in and Google Slides extension are especially relevant to teams that do not want to abandon their existing presentation software.

Who it's for

Choose Decka for editable AI-assisted slide production paired with live interaction and collaborative editing. Free is appropriate for occasional, small audiences; Pro suits recurring sessions; Badass is better for larger activities and more AI or media capacity; Enterprise is the fit for SSO, API integration, custom retention, and very large events. It is less suitable if you only need basic polling or want a plan without annual billing.

Pros and cons

Pros

• AI drafts remain fully editable, allowing presenters to correct layout and content instead of starting over.
• Presentation creation and polls, quizzes, Q&A, word clouds, drawings, and games share one workflow.
• Real-time co-editing, collaborator invitations, and view-only links support team delivery.
• Enterprise combines API access, SSO/SAML, custom retention, and dedicated support.

Cons

• The free tier permits only two live sessions and 200 participants per month.
• Pro and Badass require annual billing, even though prices are expressed monthly.

Alternatives

For a broad comparison, see Interactive Presentation Software. Poll Everywhere is a better fit when mobile apps, a free trial, or a 40-person free audience are priorities. Choose livepoll.io for up to 1,000 participants per session with unlimited questions and sessions on its free plan. Nearpod is oriented toward lessons, with student-join limits and classroom-focused plans. AhaSlides suits users wanting unlimited free presentations with up to 50 participants. EngageSlide offers a smaller 10-person free live audience alongside broad slide support. StreamAlive is worth considering for unlimited free sessions when five participants per session is enough. LessonUp targets interactive teaching, while Socrative focuses on quizzes and classroom assessment.

Verdict

Decka is a strong choice for teams that want to turn AI-generated slides into collaborative, audience-driven presentations without switching between separate tools. Choose it when editable design control and varied live activities matter most. Look elsewhere if your priority is a generous free audience, monthly payment flexibility, or a specialist classroom or polling product.
