Files, images and the web

Drop files onto the board, paste them, or use Add images or documents, the paperclip on the tool rail (9). Several files land side by side where you dropped them, and files dropped inside a frame join it.

Images

PNG, JPEG, WebP and GIF. Shown at their own size, at most 640 pixels wide, and kept in proportion.

Documents

PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx), CSV and plain text. A Markdown file becomes a document sheet you can edit.

Web pages

An .html file, or a whole HTML page pasted in, becomes a live sheet: up to 4 MB, or 1 MB on a board kept only in your browser.

Drawings

Excalidraw and tldraw files come in as editable shapes. See Export and save.

Size

Up to 10 MB a file. Files are checked to be what their name says.

Text

Pasting a word or a line makes a text item.

Paste a link, or drag one from another tab or the address bar, and it lands as a card with the page's picture, title and a line about it. Double-click a card to open the page. Select it and the bar above has Open too, for people who can only view the board.

Links to videos, designs, pens and places play on the board itself: YouTube, Vimeo, Loom, Figma, Spotify, CodePen, Miro and Google Maps, including the short links the Google Maps app shares. They show their picture until you double-click, or press Play here, and keep playing when you click back onto the board.

A YouTube video is watched together. When someone who can edit the board plays, pauses or skips it, everyone with its player open does the same, and its picture says Playing for everyone to the others: a double-click joins at the right moment. A browser may hold the start until you click its page once; pressing play then takes you to where the others are.

Flett reads the page itself to make the card, so a page behind a sign-in shows only its address. On the front-page board, which lives in your browser, links show their address until you sign in or share the board.

Install Flett from your browser (on Android, Add to Home screen or Install app in Chrome's menu) and it appears in the share sheet of your other apps. Share a link, some text, photos or documents to Flett, pick the board, and they land where people on it are looking: the link as a card, the words as a sticky note, the files as they would if you dropped them.

Sharing to Flett works on Android, ChromeOS and Windows. iPhones and iPads do not let web apps receive shares; paste the link on the board instead. On a computer, Flett Clipper sends from any page.

Paste works the way it looks. What you copied decides what lands on the board:

A selection

A part of a web page, a table, or an answer selected in Claude, ChatGPT or Gemini lands as a document sheet that keeps the look it had, colors and fonts included.

Markdown

An answer copied with Claude's or ChatGPT's Copy button lands as a document sheet, with its headings, lists, tables and code set properly.

Claude artifacts

Copy an artifact in Claude and paste it: a page, a React app, an SVG picture, a Mermaid diagram or code all become live sheets. React apps run here as they do in Claude, with their charts, icons and buttons.

Links to artifacts

With Flett Clipper installed, pasting the link to a published Claude artifact brings the artifact itself. See Flett Clipper.

Links in sheets

Links in a sheet open in a new tab.

Something sent from another page, with Flett Clipper, shows where it came from: select it and the bar above it links back to the page.

A document shows one page, slide or sheet at a time, with previous and next buttons and a page count. Open large (or a double-click) shows every page scrolling, with a Download link.

Ask about a document on the board and the AI reads its text, page by page, stopping once it has what it needs. It reads up to 10 pages per request. For PDFs a page is a page, for decks a slide with its speaker notes, for spreadsheets a sheet; Word and text files are read in pieces of about a page.

The AI can only read files stored on the server, so on the front-page board, which lives in your browser, sign in or share first. Encrypted or damaged files cannot be read.

Select images, or name them with @, and they are attached to your message so the AI can see them: up to four at a time. It cannot see images you did not point at.

It can also show an image from the board inside a sheet it writes, such as your photo on a CV, a product shot on a slide or a logo on a card. The image itself stays where it is on the board.

Web search

When an answer depends on today or on facts it is not sure of, it searches the web first, up to three times per request, reads the best pages, and cites them as links in the sheet.

Photos

It finds real photos for designed sheets from a stock photo library, rather than making up image addresses.

Icons

It picks icons from open icon sets for pages and slides.

Searches cost a little on top of the answer, see Plans and usage.
