LinkedIn carousel generator from text, PDF, and ideas

A LinkedIn carousel is a document post. LinkedIn shows it as a swipeable deck, and the file behind that deck is a PDF. The slow part is not the upload. The slow part is deciding the point, writing the slides, and making them look like one piece instead of eight disconnected cards.

Boykli is a LinkedIn carousel generator for that job. You give it text, you pick an idea, or you start from a PDF, a Word file, or a Markdown file on Create posts and carry the lesson across. The carousel page designs the slides and hands you a PDF, a document title, and a caption. You can download the PDF or publish it to the personal LinkedIn profile you connect. The same file can sit on the queue. How that queue picks the next open slot is covered in LinkedIn scheduling tool.

The product was built so the idea stays yours. The longer version of that is building Boykli. This page is the practical map of the three starting points and the file you get back.

Where the deck starts

People search for one tool that accepts a paragraph, a PDF, and a blank-page idea. Those are three different inputs, and they land in two places in the app.

The carousel form itself is a text box. It does not take a file upload. A PDF enters as source material on Create posts, Document mode, which accepts .pdf, .docx, and .md. That mode extracts one lesson and writes a standalone post. Tones there are Teach & Explain, Analytical, Step-by-Step, and Thought Leader. You then put the lesson, or a tighter version of it, into the carousel topic and create the deck. Treating "upload a 40-page report, receive eight finished slides" as a single button would skip the edit that keeps the claim accurate.

An idea is also text. The ideas list is a catalog you search. Professional topics are grouped: Business & Startups, Career, AI, Development, Marketing, Productivity, Money, Learning, Personal Growth, Software Engineering, Business Thinking, Psychology, General, Framework Carousels, and topics that suit a visual deck. A second tab is humor, lines such as a quarterly earnings report for your motivation. Choosing a humor idea sets the humor tone so the model keeps the joke. Choosing a professional idea sets the normal tone. You can still type over the filled topic before you create.

What you set before it builds

The topic is required. Empty, and the page asks for one. Everything else has a default you can change.

Tone is Normal or Humor. Normal is the professional treatment. Humor keeps a parody as a parody. A sarcastic prompt on Normal tone gets sanded into advice. A serious framework on Humor tone gets the joke treatment. Match the tone to the topic.

Aspect ratio is Square (1:1) or Portrait (4:5). Square renders at 1080 by 1080. Portrait renders at 1080 by 1350. LinkedIn document posts accept both. Portrait gives each slide more vertical room for a short stack of lines. Square is tighter and reads more like a card.

Slide count is a range from 2 to 8. The default is 5. A framework with a cover, three points, and a close fits 5. A teardown with a setup and a numbered list often wants 7 or 8. Past 8, the form stops. If the model returns fewer slides than you asked for, the page tells you the count it got. You can post that shorter deck or run it again.

The model picker is Grok 4.6 (the default), Gemini 3.5 Flash, Claude Sonnet 5, or GPT-5.6 Terra. Same four names as the rest of carousel generation. There is no silent swap to a different model if one of these is selected.

Design is a named look, not a blank canvas of text boxes:

Brand kit lives on the carousel page, next to the form. It stores canvas color, accent color, logo, profile photo, and LinkedIn handle. You can show or hide the author strip and the logo. If brand colors are on, the only design available is Normal. The other seven designs stay in the menu and stay disabled until you turn brand colors off. Save the kit before you create. An unsaved change blocks the button so a deck does not render against colors you have not stored. Colors, the type ramp, and how each layout uses the kit are in LinkedIn brand kit.

Slides are HTML and CSS: type, shapes, gradients, and SVG. The generator does not place a photograph on a slide. A separate image generation exists for a single image that is not a document post. Those two outputs are different files. How a native multi-image grid compares with this PDF on layout and on engagement rate is LinkedIn multi-image post vs PDF carousel. Which of those files is a one-frame chart, which is a photo grid, and which is a numbered PDF is visual storytelling on LinkedIn.

A worked path for each input

The same five checks apply after any of the three starts. Read the slides. Fix a false claim by changing the topic and creating again. Set the document title LinkedIn shows on the file, up to 120 characters. Write the caption people see in the feed. Then download the PDF or send it to the profile.

From text

1. Open the carousel page and write the topic in plain language. A useful topic names the audience, the claim, and the shape. "Five mistakes in onboarding emails for a B2B product, one mistake per slide, last slide is the fix" is a topic. "Onboarding" is a label.
2. Set Normal tone, pick Square or Portrait, pick a design, and set the slide count to match the outline you just wrote.
3. Create the carousel. Large decks can take a few minutes. The page warns you while it is still working, and it stops the attempt at about eight minutes so a hung run does not sit there all afternoon.
4. Read every slide. The model writes the lines. A number, a name, or a promise you would not say out loud is still your post once it is on LinkedIn.
5. Edit the document title and the caption. The title is the name of the PDF on LinkedIn. The caption is the post text. They are stored separately. Publishing uses the title as the document name and the caption as the commentary.
6. Download the PDF, post it now, or put it on the schedule. Posting uses the personal profile connected with LinkedIn. Company pages, other networks, and a teammate's approval step are outside this product.

From a PDF

1. On Create posts, choose Document. Upload the PDF, Word file, or Markdown file. Stay under 7 MB.
2. Add an optional brief if the file contains more than one argument. "Use the pricing section. Ignore the roadmap." is a brief. Leaving it blank asks for one strong lesson from the whole file.
3. Pick a document tone and write the post. You get a text post, not slides. Read it the same way you would read any draft. This is the filter. A 20-page memo should not become eight slides until you know which sentence is the post.
4. Copy the lesson, or a tighter outline of it, into the carousel topic. Keep the source claim intact. Do not let the slide pass invent a statistic that was not in the file.
5. Run the text path above: tone, ratio, design, slide count, create, read, title, caption, PDF.

What the extractor keeps, what a scanned page loses, and how one lesson becomes a slide count are in How to convert a PDF to LinkedIn carousel slides.

A public blog or news URL is a different start. Article mode reads the page and writes one post. The slides still come from an outline you paste. That path is How to turn long blog articles into LinkedIn carousels.

A series of posts from one long source is a different mode, Series, and it produces several text posts. It does not produce several carousels in one click. One deck is one create on the carousel page.

From an idea

1. Open the ideas list on the carousel page and search. Professional categories are for a deck you would sign with your name. The humor list is for a bit.
2. Select one line. The topic box fills, and the tone follows the tab you picked.
3. Rewrite the line until it is specific to your work. "Skills that compound over time" is a prompt. "Three skills I kept after leaving consulting, and the one I dropped" is a carousel. The list is a start, not a script of your experience.
4. Create, read, title, caption, PDF, same as the text path.

The reason the idea has to become yours is the same reason the product exists. A shared prompt produces a shared deck. Boykli is the writing and the file. It is not a feed of someone else's winning posts.

Approaches people mix up

Boykli is the first three rows. The fourth row is a different instrument, and Canva is the editor people mean when they say it. Page size, PDF Standard, what the Content Planner will actually send, and the same outline run both ways are in Canva vs a dedicated LinkedIn carousel generator. If the work you do most is moving a headline two pixels left, a template editor is built for that. If the work you do most is getting from a note, a file, or a blank topic to a PDF you would publish, the generator is built for that.

What you pay, and what a seat includes

Prices on boykli.com are BYOK at $29 a month and Managed at $88 a month. Both seats are the same product for one person.

Managed includes the models inside monthly caps: 210 posts, 150 carousels, 150 images, 25 Voice Agent sessions, and 130 post refinements. A carousel generation is one create on the carousel page. Reading the preview and downloading the PDF again is not a second generation. Rewriting the topic and creating again is.

BYOK is the same screens with your own OpenRouter key for chat and images and your own Google AI Studio key for Voice Agent. Boykli does not add a monthly generation cap on that seat. You still pay those providers for the usage.

A paid seat is required before the app will write a post, create a carousel or an image, publish to LinkedIn, or schedule. Logged-in visitors can browse Radar and Algorithm without a seat. Browsing is not a generation trial.

What to check before you publish

• The slide count matches the argument. A cover that repeats the caption, then six slides that repeat the cover, is a failed deck even if the PDF downloads.
• Every number traces to the note or the file. The model will write a confident figure. LinkedIn will not know you invented it.
• The document title is a title, not the whole caption. LinkedIn uses it as the name of the document.
• The handle, photo, and logo in the brand kit are the ones you want on the slide. Author strip and logo are toggles.
• Brand colors and design agree. Colors on means the Normal design. A Neo-Brutalist deck means brand colors off.
• The connected account is your personal profile. The queue will not post as a company page.

FAQ

Can I drop a PDF in and get a carousel?

You can drop a PDF, a Word file, or a Markdown file into Create posts, Document mode, up to 7 MB, and get a LinkedIn post from it. The carousel page then takes the lesson as text. The PDF you download at the end is a new file, the slide deck, which is what LinkedIn publishes as a document post.

Does the generator also accept a plain idea with no draft?

Yes. Type it, or pick one from the ideas list and rewrite it. The list covers professional categories and a humor set. The topic box holds up to 2,000 characters, which is enough for a real outline.

How many slides, and which shape?

From 2 to 8 slides. Square is 1:1 at 1080 pixels. Portrait is 4:5 at 1080 by 1350. You choose before you create.

Can I edit the words on a slide after it renders?

You edit the document title and the caption directly. Slide copy is part of the generated design. To change a line inside a slide, change the topic and create again. There is no per-box editor and no drag layout. A template product is the other category, described on the Supergrow alternative page.

Which model designs the deck?

Grok 4.6, Gemini 3.5 Flash, Claude Sonnet 5, or GPT-5.6 Terra. Grok 4.6 is the default.

Will my logo and colors show up?

Yes, from the brand kit on the carousel page: canvas color, accent color, logo, profile photo, and handle. Brand colors lock the design to Normal. The other designs, including the Neo-Brutalist default, are available when brand colors are off.

Can I schedule the PDF?

Yes, on the personal profile you connect. You choose the days, the time of day, and the timezone. The next item takes the next open slot. The queue does not pick a time from analytics, and it does not post to a company page. Details are in LinkedIn scheduling tool.

What does a carousel cost?

The seat is $29 a month on BYOK or $88 a month on Managed. Managed includes 150 carousel generations in the month, inside the wider caps. BYOK has no Boykli monthly cap, and your OpenRouter bill is separate. Creating requires the seat.
