Twelver — AI Browser Agent & Assistant

Twelver (twelver.app) is an AI agent that works right inside your browser. Describe a task in plain words, and it opens the sites it needs, reads the pages, clicks buttons and fills in fields. It works in its own tabs, under your own logins, and you can watch every step. It isn't another chatbot that only talks. It finishes the job on the website: it finds, compares, collects and brings back a ready answer, a summary or a draft. Then you can keep working with that result in the same window: turn it into a document, a slide deck, a cover, a voiceover or a short clip. TWELVER IN SHORT Twelver is one workspace with models for text, images, video, speech and music. This extension is its hands on the web: it lets your Twelver assistant open pages and act on them. You can start without a card. WHAT YOU CAN HAND OFF Shopping and research • Find five used laptops under $400 on a marketplace and list them with links, price and condition. • Compare the price of one product across several stores, with shipping and delivery times, in one summary. • Pick a product by its specs: open the listings, note the differences and say which fits your needs. • Check whether a size or model is in stock without opening a dozen tabs yourself. • Gather reviews of a product or company from several pages and sum up the pros and cons. • Find flights, hotels or restaurants that match your terms and list the options with links. You make the booking. Sellers and small business • Read new reviews in your seller dashboard and draft a reply to each, then type the replies into the fields. You confirm sending. • Go through competitors' product pages and note their prices, specs and promotions. • Rewrite a product description to your brief and paste it into the edit field. • Check that your listings have every required attribute filled in and make a list of gaps. Marketing, sales and office work • Visit competitors' sites and compare their prices, terms and offers. • Pull data from pages (specs, contacts, lists, schedules) without copying by hand. Web scraping with no code and no setup. • Fill in a repetitive form or questionnaire with details you gave in a message or attached as a file. • Go through your CRM, inbox or account dashboard, find the records you need and write them into a report. • Find job openings that match your profile and collect them with links and salaries. • Build a list of companies from a directory, with websites and phone numbers. Content and social media • Open competitors' social pages and note the topics of their latest posts. • Collect ideas and facts on a topic from several sites and turn them into a monthly content plan. • Find this week's industry news and write a short digest with links. Home and everyday life • Find a recipe for what's already in your fridge and make a shopping list. • Compare phone, internet or insurance plans on providers' sites and spell out the differences. • Check opening hours, timetables or appointment slots. • Fill in an application form with your details and stop before sending. Study, documentation and reference • Find the answer in a long page or documentation: it searches for the right spot by meaning instead of scrolling through everything. • Open several articles on a topic and build an overview with sources. • Find rules, rates or terms on an official site and explain the key points in plain words. • Check the data on a page against your file and show the mismatches. EXAMPLE REQUESTS Copy any of these as is: • "Open news.ycombinator.com and tell me the top 3 stories." • "Compare the price of this vacuum in three stores and tell me where it's cheapest with delivery." • "Open my seller dashboard, read this week's reviews and suggest replies." • "Collect the name, price and link of every product on the first page of this catalog." • "Find the deposit terms on this bank's site: rate, term and restrictions." • "Open the docs and find how to set up webhooks, with an example." • "Read this article and turn it into an 800-character post with a cover image." WEBSITE + EVERYTHING ELSE TWELVER DOES The point of Twelver is that what it finds on a site doesn't get stuck in the conversation. Tasks it does end to end: • Read your listing, rewrite it to sell better and paste the text into the field. It draws a new cover right there, and you download it in one click. • Collect competitors' prices from their sites and lay them out as a table and a presentation for your meeting. • Study a product page and make a marketplace card or an infographic at the right size, as a PNG. • Read an article and turn it into a post, a script for a short clip or an audio version read by a narrator. • Gather data from several pages and build an interactive dashboard page you can share by link. • Find a photo on the web, or check where else your own picture appears. WHAT ELSE TWELVER CAN DO All of this lives in the same place where you give it website tasks. Writing and documents • Articles, posts, emails, reports and résumés, in English, Spanish, Russian and other languages. • Reading your files: PDFs (scans included), documents, spreadsheets, slides, photos, audio. Summaries, search inside a file, comparing several files, pulling out numbers. • Code in any language: scripts, scrapers, bots. Python runs right in the window. Presentations and websites • 16:9 or vertical slide decks with a presenter mode and PDF export. • One-page sites, landing pages, calculators and dashboards that work instantly and open by link. Images and design • Image generation from a description, from one picture or from several at once. • Photo edits by description: remove an object, swap the background, change the style. • Background removal, transparent PNGs, legible text right on the picture: posters, logos, signs. • Marketplace product cards, infographics, covers and social posts at ready-made sizes. Video • Clips from text or a still: bring a still to life, make a scene up to 30 seconds with sound. • Rem…
