What it can do
| Tool | What it says it does |
|---|---|
cotlet_app_guide | How to work in an app by clicking in the user's Cloud Browser with Cotlet's browser tools: which browser to use for this workspace and the sign-in link, the method step by step, the app's screens, menus and actions, notes, and the app's dedicated tools when Cotlet has them. Call it before the… |
cotlet_apps | The apps of the user's workspace and whether each works now: access granted or requested, the app account in the user's Cloud Browser (connected, signed out, signed in but not connected), and the one step the user has to take, with the console link. Free. Needs the user's Cotlet API key or… |
cotlet_balance | The user's current credit balance. Free. Needs the user's Cotlet API key or sign-in. |
cotlet_browser_click | Clicks element `element`, or point `x`, `y` of the screenshot; `double` double-clicks, `button: right` right-clicks. Answers the page after it: the elements and text in view, with the same numbers. Says when nothing changed. A link that would open a new tab opens in this one. Buttons that pay or… |
cotlet_browser_close | Ends the browser session when the task is done: the browser keeps its cookies and sleeps, and the per-minute charge stops. Answers the session's minutes and credits. |
cotlet_browser_download | Gets the file that clicking `element` (a download link or button) or opening `url` starts: answers its name, type, size and a link valid 15 minutes; CSV, JSON and other text files also as text. |
cotlet_browser_drag | Drags from one element or point to another: a card between columns, a piece on a board, a slider's handle. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_evaluate | Runs a JavaScript function body on the page and answers what it returns, as JSON. Use it to extract data the page holds (a table, a list, attributes); act with the other tools. It cannot send requests, click, submit, or read cookies or storage; a filled field's value reads [hidden by Cotlet]… |
cotlet_browser_fill_form | Fills several fields in one step: text fields take text, drop-downs an option's label, checkboxes, radios and switches true or false. Stops at the first field that fails and names those filled. Does not send the form: click its button after. Answers the page after it: the elements and text in… |
cotlet_browser_find | Finds `text` on the whole current page, frames included: the elements whose label holds it, with their numbers, and each line of text that holds it. Use it instead of reading or scrolling a long page for one thing. |
cotlet_browser_hover | Rests the pointer on an element or a point, to open a hover menu, a tooltip or a preview. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_navigate | Opens `url` in the current tab, or goes `history` back or forward. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_open | Starts the user's Cloud Browser (a real Chrome on Cotlet, where the user is signed in to their sites) and opens `url`. Call it first. The URL goes to the site's open tab, else to a new tab, so the user's own tabs stay. Answers the page after it: the elements and text in view, with the same… |
cotlet_browser_press | Presses a key on the focused element: Enter to send, Tab to the next field, Escape to close a pop-up, arrows in a list or slider, or one character (a site's shortcut). Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_read | The whole current page: its text (up to 20,000 characters) and a numbered list of its links, buttons, fields and other controls, open dialogs first. Use it on a new page or when a step's answer is not enough; `element` reads only inside one element (a dialog, a form, a list). Never returns field… |
cotlet_browser_screenshot | A JPEG of the visible part of the page. Use it for boards, canvases, maps, charts and layout that the text does not show, then click or drag by `x`, `y` of the image. |
cotlet_browser_scroll | Scrolls with the mouse wheel: `down` or `up` by `screens`, to `top` or `bottom`, until `element` is in view, or inside a panel or list (`inside`). Content that loads on scroll appears. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_select | Chooses `option` (its label as listed, or its value) in drop-down `element`. For a home-made drop-down, click it, then click the option. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_tabs | The tabs of the user's web browser, where they keep their signed-in sites open. `list` (default) answers each tab's id, URL and title and which is shown; `switch` with `tab` shows that tab, and every later step acts on it; `new` with `url` opens a tab (at most 8); `close` with `tab` closes it… |
cotlet_browser_type | Types `text` into field `element`, replacing what it held; `submit` presses Enter after it. For several fields use fill_form. Answers the page after it: the elements and text in view, with the same numbers. Password, card and one-time code fields are refused: the user types them. |
cotlet_browser_upload | Puts files into file field or upload button `element`: each file is {"url": "https://..."} or {"file_id": "..."} of a file uploaded to Cotlet; up to 10 files, 20 MB each. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_browser_wait | Waits until `text` shows on the page (at most `seconds`, default 5, up to 20), or just `seconds`: for results that load slowly. Says whether the text appeared. Answers the page after it: the elements and text in view, with the same numbers. |
cotlet_get_call | Status of an earlier Cotlet call, by its call_id: pending (waits for the owner's approval in the Cotlet console), approved, running, success, rejected, expired, blocked or failed. For a call that answered with status pending or running. |
cotlet_report_issue | Sends a report to the Cotlet team: a tool that failed or returned wrong data, an error you could not get past, or a step the browser could not do, with the page, the step and what you saw. A missing dedicated tool is not a problem to report: do the task in the browser. A feature the user asks for… |
cotlet_request_apps | Requests access to apps for the user's workspace, as Request access in the console: every app is granted at once. Not needed to work in an app: the user's AI works in any web app in their Web browser with cotlet_app_guide. An app with dedicated tools gets them after the user signs in to it in… |
cotlet_upload_file | Returns a one-time upload_url and a file_id for a local file (an image for a post, an attachment). The file is sent to upload_url with an HTTP PUT; an argument that takes a file accepts {"file_id": "..."}. Up to 25 MB, the URL works once. Free. Needs the user's Cotlet API key or sign-in. |
cotlet_whoami | The Cotlet account this connection acts as: email, workspace, access status, the API key or OAuth client in use with its scope, the apps the workspace may call and its credit balance. Free. Needs the user's Cotlet API key or sign-in. |
In its maker's words
Cotlet's own tools: a cloud browser signed in as the user, account, credits and calls.
