Frontier reasoning models, built in

Superintelligence for presentations

The hard part of a deck was never the slides. It was reading the material, finding the argument, and deciding what goes on screen. ChatSlide hands that to frontier reasoning models — and hands the judgement back to you.

What the intelligence is actually doing

Most "AI presentation" tools use a model to rephrase bullets you already wrote. The work worth automating happens before that.

It reads the whole source, not a sample

A 100-page PDF, a spreadsheet, a YouTube transcript, a URL, or all of them at once. The model builds the narrative from the full document instead of keyword-matching a summary.

It decides the structure

Which point is the thesis, which belongs on one slide, which is a chart rather than a bullet. Structure is the part most tools skip and the part that makes a deck land.

It writes the words you will say

Speaker notes and narration are generated with the slides, so the script matches what is on screen. Voice cloning and AI avatars turn that script into a video.

It works across languages

Generate in one language and translate the deck, the notes, and the narration together — layout preserved, numbers untouched.

The model stack, by plan

No mystery "proprietary AI". These are the models that run your generation, and you pick one per deck.

Plan	Price	Model	What it is for
Free	$0	DeepSeek V4	Fast drafting. Good enough to see the shape of a deck before you pay for anything.
Plus / Pro	from $14.9/mo	GPT-5.5	The default working brain: outline, slide copy, speaker notes, chart selection, translation.
Ultimate	$59.9/mo	GPT-5.6-sol reasoning	Long-chain reasoning for dense source material — clinical papers, financial models, 100MB of mixed documents.

Where it stops, and you start

It does not verify facts in your source. If the input is wrong, the deck is wrong, confidently.
It does not know your audience, your politics, or what your CFO said last quarter. You do.
Numbers come from your file, never invented — but the reading of them is yours to approve.
A model is one part of the pipeline. Layout engine, export, fonts, and templates do the rest.

Frequently asked questions

What does "superintelligence" mean in ChatSlide?

Concretely: frontier reasoning models doing the work a human analyst used to do before slide one — reading the source material end to end, deciding the argument, choosing what becomes a chart, and writing the script you will actually say. ChatSlide runs DeepSeek V4 on the free plan, GPT-5.5 on paid plans, and the GPT-5.6-sol reasoning model on Ultimate. It is not a general intelligence claim; it is the best available reasoning applied to one job.

Which model generates my deck?

It depends on your plan. Free uses DeepSeek V4, Plus ($14.9/mo) and Pro ($19.9/mo) use GPT-5.5, and Ultimate ($59.9/mo) adds the GPT-5.6-sol reasoning model for long or technical source material. You can see and change the model per generation.

Is a reasoning model worth it for slides?

For a short topic deck, no — GPT-5.5 is already past the point where the bottleneck is the model. For a 60-page clinical paper, a dense financial appendix, or a deck that has to survive expert questions, reasoning changes the output materially: fewer dropped caveats, better chart choices, a narrative that holds across 40 slides.

Does superintelligence mean I stop editing?

No, and any tool that promises that is selling you a first draft as a final one. The model gets you a structured, on-brand, fully written deck in minutes instead of hours. Judgement about emphasis, audience, and what to leave out stays with you, which is why every slide, note, and chart stays editable.

Can it make the video too?

Yes. The same generation produces slides, speaker notes, and a narration script; voice cloning, AI avatars, and video export turn that into a finished video without a separate tool or a second pass at the script.

Can I keep my source material private?

Yes. Private projects are available on Pro and above, so a deck built from internal material is not visible in the public gallery.
