Tosea.ai

Tosea.ai is a web-based AI presentation assistant built by Tosea Tech Limited, a company registered in Hong Kong. It takes uploaded documents—PDFs, research notes, reports—and converts them into structured, editable slide decks, with a stated emphasis on reproducing charts, formulas, and data exactly as they appear in the source rather than generating invented content.

What It Is

Tosea.ai sits in the AI presentation generation category, specifically targeting professionals who need to turn dense source documents into presentation-ready slides quickly. The core workflow is document-in, slide-deck-out: users upload a file, interact with an AI assistant to define emphasis, audience, and depth, and receive a multi-slide deck with speaker notes. The tool positions itself around evidence fidelity—its homepage states "AI does not invent — it transcribes faithfully. Charts, formulas, and data are reproduced 1:1 from your source."

How the Workflow Operates

The creation process follows three explicit stages shown on the product page:

• Evidence-driven extraction: The AI reads the uploaded document and surfaces figures, tables, images, and formulas from the source file.
• Outline building: Users guide the AI to add sections, adjust narrative structure, and refine the story before slides are generated.
• Slide refinement and export: Individual slides can be adjusted with AI assistance—either layout-only or full content edits—and then exported as presentation-ready files (PPTX and PDF formats are referenced in the FAQ).

The homepage demo shows a conversational interface where the user specifies audience type (e.g., investment committee vs. sales distribution), emphasis areas, and depth level before generation begins.

Template Library and Design Coverage

Tosea.ai ships with a large library of crafted templates spanning multiple verticals. The homepage showcases categories including business, brand identity, pitch decks, annual reports, healthcare, real estate, ESG, fintech, editorial, and education. Template names visible on the page include Spotlight, Impact Red, Strategy Navy, Boardroom Amber, and dozens of industry-specific designs. Templates range from 6 to 10 slides in their preview form.

Target Audience

The product page testimonials (vendor-published) describe use cases from investment managers, strategy consultants, postdoctoral researchers, startup founders, and curriculum designers. The hero section specifically calls out credit research and investment committee decks as a primary use case, with the demo showing a Barclays research note being converted into a 14-slide committee deck. The FAQ notes the tool works across finance, consulting, medicine, legal, and research verticals.

AI Model Access

The docs reference a Model Guide for choosing the right AI model. The pricing tiers distinguish between "basic models," "premium models," and "advanced + flagship models," with the homepage showing Google Gemini (specifically "Gemini 3 Flash") referenced in the demo interface. Higher tiers unlock flagship compute lanes described as "faster, more stable generation."

Platform and Deployment

Tosea.ai is a web application accessible via browser with no local installation required. Free tools are also available without an account, including PDF to PPT conversion, PDF merging, PowerPoint to PDF, PowerPoint compression, and PDF to Word. The main AI presentation creation requires account sign-up. A Discord community and changelog page are linked from the footer, indicating active product development.
