Launch HN: Poly (YC S22) – Cursor for Files

Hello world, I am Abhay from Poly (https://poly.app). We’re building an app to replace Finder/File Explorer with something more intelligent and searchable. Think of it like Dropbox + NotebookLM + Perplexity for your terabytes of files. Here’s a quick demo: https://www.youtube.com/watch?v=RsqCySU4Ln0.

Poly can search your content in natural language, across a wide range of file types, and down to page, paragraph, pixel or time point. We also provide an integrated agent that can perform actions on your files such as creating, editing, summarizing, and researching. Any action you can take, the agent can also do it for you, from renaming, moving, tagging, annotating, and organizing files. The agent can also read URLs, YouTube links and search the web and even download files for you.

Here are some public drives you can check out (Note: This doesn’t work in Safari yet – sorry! We’re working on it.)

Every Issue of the Whole Earth Catalog: https://poly.app/shared/whole-earth-catalogues

Archive of old PlayStation manuals: https://poly.app/shared/playstation-manuals-archive

A short collection of Orson Welles interviews and commercials: https://poly.app/shared/orson-welles-archive

Archive of Salvador Dali’s paintings for Alice in Wonderland: https://poly.app/shared/salvador-dali-alice-in-wonderland

To try it out, navigate to one of these public folders and use the agent or search to find things. The demo video above can give you an idea of ​​how the UI roughly works. Click on the files to select them. Quick view by pressing space. Open details of any file by pressing Cmd + i. You can search from the top middle bar (or press cmd + K), and all searches will use semantic similarity and search within files. Or use the agent from the bottom right tools menu (or press cmd + ?) and you can ask about files, have the agent search for you, summarize things, etc.

We decided to build it in March 2022 after launching an early image-gen company, and realizing how painful it was for users to store, manage, and search their libraries, especially in the world of generative media. Despite having over 150,000 users on our service at the time, we realized that our real calling was to fix file browsers to make them intelligent, so we shut down our service in 2023 and focused on this.

We believe Poly will be a great fit for people who want to do useful things with their files, like summarizing research papers, finding the right media or assets, creating shareable portfolios, searching for a particular form or document, and generating reports and overviews. Of course, this is also a great way to organize your GenAI assets. Or just use it to organize notes, links, inspo, etc.

Under the hood, Poly is built on our advanced search model, PolyEmbed-v1 that natively supports multimodal search across text, documents, spreadsheets, presentations, images, audio, video, PDF, and more. We allow you to search based on phrase, file similarity, color, face and many other types of attributes. The agent is particularly adept at using search, so you can type in something like “find me the last lease contract I signed” and it can search, reading the first few files, searching again if nothing matches, etc. But the quality of our embed model means it almost always finds the file on the first search.

It works equally well on the web and desktop, except on desktop it syncs your cloud files to a single folder (just like Google Drive). On the web we use clever caching to enable offline support and file conflict recovery. We’ve worked hard to make our system faster than your existing file browser, even if you’re using it from a web browser.

File storage plans are currently as follows: 100GB free tier, paid tier is 2TB at $10/m, and 1c per GB per month on top of 2TB. We also have rate caps for agent usage that vary at different tiers.

We’re excited to expand with tons of features over the next months, including “virtual files” (storing your Google Docs in Poly), sync from other hosting providers, mobile apps, an MCP ecosystem for agents, access to web search and deep research modes, offline search, local file support (on desktop), third-party sources (WebDAV, NAS), and more.

Our waitlist is now open and we’ll be admitting people starting today! Sign up at https://poly.app.

We’d also love to hear your thoughts (and concerns) about what we’re building, as we’re still early in this journey so your feedback could greatly shape the future of our company!
