Presento SI
AN EPIPHANI STUDIOS APP FOR MAC
Talk to your deck.

WHY PRESENTO
One investor deck went to version 60. Presento SI keeps every version and makes the next one faster.
Presento SI started with an investor deck that went from version 3 to version 60, built by hand in HTML and printed through Chrome. It worked because a page written in HTML prints as designed, and because every version was kept. Presento SI turns that method into software and takes the friction out: you point, the AI edits the page, the checks run, and the version is saved before you look up.
HOW IT WORKS
Five moves, from one instruction to the PDF you send.
Every picture on this page is the real app, working on Ferro One, a sample launch keynote for an espresso machine, built from one of Presento SI's templates.
Talk to one page, or to the whole document.
Click a page in the strip or any element on it and say what you want. The AI reads the page, edits the HTML, runs the checks, and shows you the result. Choose the model and the effort for each document, and type or dictate.
- The scope chip names what the AI is working on: “Page 8, Weekly shots brewed on Ferro machines, by quarter.”
- Quick actions on every page: Mark, 3 variants, Tighten, More visual, Fix checks
- The microphone uses Apple speech recognition, on device where your Mac supports it
Tap, circle, or draw an arrow. The AI sees exactly what you mean.
Words are slow at pointing. Press Mark, circle the bar or tap the headline, and Presento SI maps each mark to the elements underneath it, numbers it, and sends the AI a marked picture of the page with your request. “This” and “here” finally mean something.
1Page 8 · “386k”
Ask for three versions. Pick the one that lands.
Say “three variants of this page” and Presento SI lays them out side by side as real printed pages. Version A is always the page as it stands, so the choice is between what you have and three ways forward. Pick one and it replaces the page; the others stay with the version for later.
- Variants render as finished pages, never as sketches
- One request produced the three new layouts here, B to D, in 96 seconds
Every turn is a revision, with a picture of every page it changed.
History reads like a timeline: what you asked, who made the change, which pages moved, and a thumbnail of each. Switch to one page to see only its story, then restore that single page from any earlier revision while the rest of the document stays as it is. Name a revision as a final and it is starred for good.
- Whole-document or single-page history
- Restore one page from any revision, saved as a new revision
- Named finals: “Version 1 (Launch day)”
Checks run on every page. The PDF prints as it reads.
Before a change reaches your document, Presento SI checks every page for overflow, footer collisions, missing images, fonts that failed to load, contrast, and the voice and number rules your template carries. Export writes a named PDF, “Ferro One Launch Keynote - Version 1 (Launch day).pdf”, printed with Chrome's print engine at the page size the document declares.
- Overflow, footer, image, font, contrast, voice, and number checks on every page
- Named exports that say which version they are
- Speaker script drafted from the pages, one section per page

FEATURES
History, templates, checks, and exports, on your Mac.
Library
Every presentation and document in one window, newest first, each with its latest change and its finals. Open any one on its history, or fork it as a new draft.
Locked pages and elements
Lock the pages that are done, or one chart, quote or figure inside a page. The AI edits around them, and Presento SI puts back anything a turn touches.
Fork and import
Import any HTML deck and its images come with it. Fork a document to start a new draft with its own history.
Dictation
Press the microphone or Shift Command D and talk to the page. Apple speech recognition, on device where your Mac supports it.
Live numbers from a spreadsheet
Link a CSV or Excel file and bind the figures on your pages, chart bars included. Change a number in the sheet, press Refresh Numbers, and every bound figure and bar redraws.
Speaker script
The AI drafts a script from your pages: an opening line, the points, the proof, and a target time for each page.
Keyboard first
130 commands and 101 shortcuts, a Command K palette over commands, pages, documents and templates, single keys for the moves you make most, and every shortcut yours to remap.
Present like a keynote
Full screen with a presenter console on a second display. Rehearse with your script and a timer, then point with a laser, a spotlight or a zoom. A kiosk loop runs a deck on its own.
Re-flow into any form
Turn a deck into a memo, one-pager, letter, press release or email, or a memo into a deck. Presento SI starts the new document from the right template and carries your content, script and numbers across.
Paste a picture as a page
Paste a screenshot of a table or a slide, and the AI rebuilds it as a real page in your template, every number intact and ready to edit.
Compare pages
Put any two pages side by side, or a page beside an earlier version of itself, and step through the document with the arrow keys.
Links and Shortcuts
Copy a link to any page. presento:// links open a document at a page, start a presentation or run a command, so Apple Shortcuts and your other apps can drive Presento SI.
Hall of Champions
144 landmark decks, keynotes, brochures, and annual reports, each with what makes it work, plus 27 founder talks behind them. Ask the AI to build a page in the spirit of any of them.
Automatic updates
Presento SI checks for a new build when it opens and every six hours, installs it in the background, and waits while the AI is mid-turn. Every build is notarized by Apple.
The same app on the command line
The Presento SI binary also runs as presento, so any AI agent, script, or terminal can create, render, check, version, and export documents with the same engine the app uses.
# start a deck from a template, render it, check it, keep a version presento new --kit precision-tech-launch-deck --title "Ferro One Launch Keynote" presento render presento check presento snapshot -m "Sharper close" presento final 4 --label "Launch day" presento export
TEMPLATES
Start from a template with its page size, layouts, and checks already set.
33 templates, each with its own page size, layouts, content rules, and checks, and a finished example document. Pick one, give it your brand, and the AI writes inside its rules.
WHAT YOU CAN MAKE
Built for the documents that decide things.
A quarterly deck where every number has to match the spreadsheet.
“Update the figures from this file and show me which pages changed.”Agenda, summary, decisions, appendix, in the same system every quarter.
“Review the whole deck page by page without changing anything.”One idea a slide, the number as the graphic, a script to present from.
“Make the key numbers pop; nothing else moves.”Full-bleed plates, tinted paper, print-ready at the trim size.
“Three variants of this cover.”The answer, one hero figure, three proof points, the decision.
“Tighten the copy to one idea.”Postcards with bleed and 600 pixel emails from the same source.
“Match the back of the card to the front.”WHAT RUNS WHERE
Your plan, your files, your Mac.
Presento SI is a native Mac app that drives your AI agent, prints through Chrome, and keeps every document as a folder you own.
Presento SI drives the AI agent you already pay for (Claude Code on your Claude plan), so every turn rides on that plan.
PDFs print through Google Chrome at the page size each document declares, so the file you send matches the page you approved.
A document is a folder: one HTML file, its images, its speaker script, and its full history. Keep it in Dropbox or Git; any AI agent can open it.
The AI works in a staging copy. Changes inside your selection land after every page is checked; a change outside it waits for your approval.
Every build is signed with an Apple Developer ID and notarized by Apple, and updates install from the same signed feed.
Every revision is stored inside the document's own folder, so copying the folder copies its whole history and its named finals.

QUESTIONS
Requirements, files, and updates.
What do I need to run Presento SI?
A Mac with Apple silicon on macOS 15 or later, Google Chrome (Presento SI prints with Chrome's print engine), and an AI agent signed in to your own plan (Claude Code on a Claude plan). Presento SI runs every turn on that plan.
Can my own AI agent drive Presento SI?
Yes. The presento command opens a turn, reads, edits, creates and deletes pages, searches, checks, renders, and accepts or rejects; presento mcp serves the same 16 tools to any agent that speaks the Model Context Protocol. Every edit lands in a staging copy, and only accept changes the document.
Can the AI change pages I did not ask about?
Every turn runs in a staging copy. Presento SI compares every page to the version before it, and a change outside your selection waits for your review before it lands. Locked pages refuse edits until you unlock them.
Where are my documents stored?
Each document is a plain folder on your Mac: one HTML file, its images, a speaker script, and the full version history. Put it in Dropbox or a Git repository and it travels with you.
Can I bring in a deck I already have?
Yes. Import any HTML deck or document and its images come with it. Fork an existing document to start a new draft with its own history.
Why HTML and not slides?
A page built in HTML and CSS gives the AI direct control over type, grid, and page breaks, and it prints as designed. You never touch the code unless you want to; you talk to the page and point at it.
What is a final?
A final is a revision you name, like “Version 1 (Launch day)”. It is starred in History, and export uses its name in the file, so everyone knows which version they are reading.
How do updates work?
Presento SI checks for a new build when it opens and every six hours, installs it in the background, and holds an install while the AI is mid-turn.
Who makes Presento SI?
Epiphani Studios, the studio behind PageHawk, Hush Performance, and a family of focused apps. Write to us at hello@epiphani.studio.
Your next deck starts with one sentence.
Download Presento SI, pick a template, and tell the AI what the first page should say.
Everything is included in the 14-day trial. $79 once keeps Presento SI for good, with a year of updates; $39 a year keeps updates coming after that.
No AI plan of your own? Presento SI AI runs it for you: $15 a month for 250 turns, and $10 for 100 more. A turn is one request, however many steps it takes; a turn on the stronger model counts as two.
