Problem it solves: Valuation models can become difficult to follow when assumptions, formulas, and results are spread across a large spreadsheet. Valuation Lab keeps the calculation and its intermediate steps in one guided workspace. Privacy: Your valuation inputs, cases, and saved work stay in your browser. The site still makes normal hosting requests, and the app checks that it is running from its official address. These requests do not include your valuation content. See the Privacy page for details. What makes it different: - A DCF workflow with four input modes: direct free cash flow, EBITDA, revenue and costs, or an advanced EBIT-to-FCF bridge. - Terminal value by perpetual growth, exit EBITDA multiple, or exit revenue multiple, with a live cash-flow preview and implied revenue growth for each forecast year. - EBITDA, EBIT, and revenue multiple calculations using the metric and multiple you provide, plus a back-calculator for the multiple implied by a target enterprise value. - An equity bridge from enterprise value to equity value using cash and debt, with value per share when equity value is positive and a valid fully diluted share count is entered. - An optional WACC calculation helper beside the discount rate, with cost of equity from a build-up or from CAPM, and only the applied rate saved. - A 3 by 3 DCF sensitivity table showing how the result changes across the discount rate and terminal assumption. - An equity calculator for exploring the ownership percentage and implied price per share associated with an investment amount. - Separate company cases, saved valuation runs, side-by-side comparisons, and draft inputs stored in the browser. - PDF and text summaries, plus project export and import as JSON.

Problem it solves: Typing a whole sentence before realising you were on the wrong keyboard layout means deleting it and starting over. Privacy: Fully local and private - no account, no network requests, no data collection. Everything runs on your device. What makes it different: - Recovers the words you actually meant to type - it is a keyboard-layout corrector, not a translator, so it never changes the language of your text. - Works in both directions - your language to English and English back again. - Five languages - Persian, Arabic, Russian, Ukrainian and Greek, each mapped from the standard Windows layout. - Fixes text in place in text fields, search boxes and editable content; on read-only pages the corrected text is copied to your clipboard instead. - Four ways to trigger it - right-click menu, keyboard shortcut (Ctrl+Shift+U by default), an optional floating quick-fix button, and a toolbar popup converter. - Works out Shift and Caps Lock slips word by word and preserves details like the Persian آ. - Learns your keyboard variant as you use it, such as the two Persian standards. - Guesses your language from the browser on install, so most people never open settings.

Problem it solves: Describing exactly which part of an image you want changed is slow and imprecise when you only have words. Privacy: Works locally in your browser. No account, no server, no analytics - your images are never uploaded anywhere. What makes it different: - Solves the core failure of AI image editors - they change the wrong area, because words alone can't say precisely where an edit belongs. - Draw numbered rectangles on the image and write one instruction per region, so each edit is tied to an exact area. - Generated prompt includes pixel coordinates, percentage coordinates and plain-language locations, so any AI editor can follow it. - Add global instructions and explicit "do not change" rules to preserve lighting, camera angle, style or background. - Exports an annotated PNG reference image with the numbered markers alongside the prompt. - Open an image straight from any page via right-click, or paste and drag images into the editor. - Use it in a tab, a popup window, or a floating panel. - Editor-agnostic - it builds the prompt, so it works with whichever AI image editor you already use.

Problem it solves: Built-in screenshot tools only capture what's on screen, so long pages and scrollable panels get cut off. Privacy: Runs entirely in your browser. No data collection, no accounts, no remote servers. Screenshots never leave your machine. What makes it different: - Unfolds scrollable panels and iframes to their full content before capturing, then restores the page exactly as it was. Most tools stop at the scrollbar. - Captures cross-origin iframes and embedded frames that other full-page tools skip. - Four capture modes - visible area, full page, pick element (hover and click a panel, table or chat pane), and drag-to-select area. - Adjustable selection - resize handles, drag to move, size badge, and auto-scroll when dragging past the screen edge. - Built for chat histories (ChatGPT and web chat apps), long feeds, code boxes and dashboards captured in full. - Wakes lazy-loaded content before the shot so nothing renders blank. - Output as PNG or JPEG with adjustable quality - download, copy to clipboard, or open in a preview tab. - Falls back to Downloads with a warning if a custom subfolder can't be written, so a shot is never lost.
