Free AI Tools

Thirteen tools powered by real AI models: remove backgrounds and objects, upscale photos, read scans, transcribe speech, generate subtitles and voices, and chat with your documents. The twist that makes them different: the model downloads to your device, so your files never upload to anyone.

AI runs on your device No uploads, ever Works offline once loaded Free, no watermarks

Every AI tool, ranked by what people reach for most

Cloud AI services charge per image, per minute, or per month because a server does the thinking. Here the thinking happens in your browser, which changes everything downstream: no meters, no watermarks, and no copy of your file anywhere but your device.

  1. 1

    Background RemoverMost used

    Drop a photo, get a transparent PNG. The most requested AI edit on the internet.

    A segmentation model looks at your photo, decides what is subject and what is backdrop, and hands you a clean cutout at full resolution. The famous sites do this on their servers and watermark the free result; here the model runs on your machine, so the headshot or product photo never leaves it and nothing gets stamped on the output.

    AI Object RemoverNew

    Paint over a photobomber, wires, or clutter and AI fills the gap with background.

    The magic-eraser edit, done privately. Brush over the thing you wish were not in the photo and an inpainting model (MI-GAN, published at ICCV 2023) reconstructs what was behind it, on your own hardware. Zoom in for precision, stack removals pass after pass, hold to compare with the original, and download with no watermark.

    Audio TranscriberWhisper, locally

    Speech-to-text for interviews, meetings, and voice memos, without the audio going anywhere.

    OpenAI's Whisper model runs inside your browser and turns recordings into editable transcripts with clickable timestamps, exportable as TXT, DOCX, SRT, and more. Interviews, therapy notes, board meetings, and voice memos are exactly the recordings that should never sit on a transcription vendor's servers, and with this tool they never do.

    AI Photo Restorer

    Old, blurry, or low-quality photos of people come back to life: the AI finds every face and rebuilds it in sharp detail, with a wipe slider to compare.

    Restoration services charge per photo and restoration apps upload your most personal images to their servers. This one does the work on your device: a face detector finds every face (up to six per photo, largest first), GFPGAN rebuilds each one at high detail, and the result is blended back into your photo at its original resolution. A before-and-after wipe slider shows exactly what changed, downloads carry no watermark, and the model caches in your browser after a one-time download, so the shoebox scans of your grandparents never leave your machine.

    AI Photo Colorizer

    Black and white photos come to life in natural color: skin, sky, and foliage each treated as what they are, with a wipe slider and a vibrance control.

    Colorization services charge per photo or upload your family archive to their servers. This one runs DDColor, a modern colorization model from Alibaba's DAMO Academy, entirely in your browser: it predicts only the color layer while your photo's own brightness detail keeps every edge and grain, so nothing gets blurred. Compare with the before-and-after wipe slider, dial the vibrance from subtle vintage tint to fully saturated without re-running the AI, and download at full resolution with no watermark. It also revives faded color prints by re-coloring them from brightness alone. The model downloads once (about 54 MB) and works offline after.

    AI Image Upscaler

    Enlarge small or blurry photos 2x, 3x, or 4x with AI super-resolution.

    A plain resize makes blur bigger; a super-resolution network reconstructs plausible detail as it enlarges. Old digitized photos, small logos, and screenshots headed for print all come out sharper, and the family photo you are restoring stays on your machine the whole time.

    PDF OCR

    Turn scanned PDFs into searchable, copyable text, in 17 languages.

    Scanned contracts, old records, and paper forms arrive as pictures of text. OCR reads the pixels and gives you real, selectable text, and because scans are so often sensitive (medical records, legal documents, IDs), doing it locally is not a nicety, it is the point.

    Subtitle Studio

    Generate subtitles for any video with local speech recognition, then edit and export.

    Whisper listens to your video and drafts the captions; you fix names and phrasing on a proper editing timeline, then export SRT/VTT or burn the subtitles into the video. Captioning services charge per minute for this, and require your footage. This one takes neither your money nor your video.

    AI Document ChatLocal chatbot

    Ask questions of your own PDFs and documents, answered by a language model on your device.

    Load a contract, a manual, or a report and ask it questions in plain English. A compact language model downloads to your browser and reads the document there, so neither your file nor your questions ever reach a server. It is the ChatGPT-with-my-files workflow for the files you would never paste into ChatGPT.

    AI Meeting Notes

    A recording or transcript goes in; a summary, decisions, and action items come out. The AI runs on your device, so confidential meetings stay confidential.

    Cloud AI note-takers process your meetings on their servers, which is exactly why many workplaces ban them. This one does the same job with nothing leaving your machine: Whisper transcribes the recording in your browser, then a local language model writes the brief with a TL;DR, the decisions made, action items as tick-able checkboxes, and the topics covered. Drop the Zoom download, record live with a level meter, or paste the transcript your meeting app already made and skip transcription entirely. Everything is editable, exports as Markdown or plain text, and recent briefs stay on this device only.

    Face Blur & Photo AnonymizerNew

    AI finds every face; you choose which to pixelate, blur, or black out.

    Kids in a class photo, strangers in a listing shot, protest crowds: some faces need hiding before a photo goes anywhere. A 1.5 MB detector finds them all, you toggle each one, add manual regions for plates and name tags, and batch whole folders to a ZIP. The one tool where local processing is the entire point: anonymizing a photo by uploading it somewhere would be a contradiction.

    Image to Text (OCR)

    Extract editable text from photos, screenshots, and scans. Paste straight from the clipboard.

    The photo of a whiteboard, the screenshot of an error message, the picture of a recipe: all locked-up text until OCR reads it out. Ctrl+V an image straight into the tool, batch-convert a folder, and copy the results, in 17 languages, with nothing uploaded anywhere.

    Text-to-Speech Studio

    Natural AI voices read your text aloud, and you download the audio.

    Modern neural voices, not the robotic system defaults: paste a script, an article, or study notes and get natural-sounding audio you can download and keep. Voiceovers for videos, proof-listening your own writing, and accessibility, all generated on your device from text that never leaves it.

    Text Behind Image MakerNew

    The viral effect: AI finds your subject and weaves your text behind them.

    The big-word-behind-the-person look from wallpapers, album art, and thumbnails, automated. The same segmentation AI as the Background Remover finds your subject, and your text renders between the background and them. Drag it into place, style it, download it, no Photoshop and no upload.

    Passport & ID Photo Maker

    Compliant passport, visa, and ID photos with AI background replacement.

    Take a phone photo against any wall; the AI swaps in the required plain background, country presets nail the exact dimensions, head-position guides keep it compliant, and a print-ready sheet comes out the other end. The drugstore booth charges fifteen dollars and keeps a copy; this is free and keeps nothing.

    LLM Next-Word PlaygroundSee how AI works

    Train a tiny word predictor on any text and watch it think, one probability bar at a time.

    The odd one out on this page: instead of using AI, it shows you what AI is. Paste any text, train a miniature next-word predictor right in the browser, and watch live probability bars as it writes, with a temperature slider that reshapes the odds. The clearest ten-minute explanation of how ChatGPT-style models work that you can get for free.

    Audio Noise RemoverAI on device

    Clean hum, hiss, fan, and traffic out of a voice recording with a neural noise model.

    The air conditioner you stopped hearing years ago is all over your recording. RNNoise, the neural suppressor inside major voice-chat apps, runs as 110 KB of WebAssembly in the page: hold a button to compare before and after, dial the strength so the voice stays natural, and export WAV or MP3. Interviews and voice memos never leave your device.

    AI Caption GeneratorAI on device

    Turn a photo and a brain dump into ready-to-edit captions for X, Instagram, LinkedIn, and Facebook.

    The newest arrival. Microsoft's Florence-2 describes your photo on your device, then a local language model writes a separate caption for each platform you pick, with your choice of tone, length, hashtags, and emojis. X respects its 280 characters, Instagram and LinkedIn lead with a hook that survives the fold, and everything stays editable with a reminder to read before you post. Your camera roll and half-formed thoughts never leave the browser.

Questions people ask about browser AI

How can AI tools work without uploading my files?
The direction of travel is reversed: instead of your file going to the model, the model comes to you. Each tool downloads its AI model to your browser once, from about 4 MB for background removal to larger one-time downloads for speech and language models, and your own device runs it through WebAssembly. You can watch the network tab while using any tool and verify that your file never moves.
What AI models do these tools actually use?
Published, permissively licensed research models, credited on the licenses page: U²-Net for background segmentation, MI-GAN (ICCV 2023) for object removal, OpenAI's Whisper for transcription and subtitles, Tesseract for OCR, compact instruction-tuned language models for document chat, and Kokoro for text-to-speech.
Are browser AI tools as good as paid cloud services?
For these jobs, remarkably close, and for private files, better where it counts. On-device models are smaller than the largest cloud models, so the hardest edge cases (wispy hair on a busy background, heavy accents in noisy audio) can differ. In exchange: no upload, no watermark, no per-file fee, and no copy of your file on someone's server.
Why is the first run slower than the rest?
The first use downloads the model, which your browser then caches. After that the tool starts instantly, and because everything it needs lives on your device, most of these tools keep working offline.
Are these AI tools really free? What's the catch?
All 13 are free with no sign-up and no watermarks. Cloud AI services meter you because a server does the computing and servers cost money; here your device does the computing, so there is no bill to pass on. The site offers an optional premium plan that adds extra features on some tools and guarantees unlimited use, and that is the whole model.
Do I need a powerful computer?
An ordinary laptop or a recent phone handles all of it. The image tools run in seconds; transcription runs at a healthy multiple of real time on everyday hardware. The heavier language-model tools tell you what they are downloading up front, and everything degrades honestly instead of silently failing.
