Show HN: Simplepdf.eu – a browser-based PDF annotator / editor Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document, upon opening it you'll see fields already set, ready to be filled-in, think crowd-sourced fields positioning – saving you time and effort. --- # How does the crowd-sourced positioning of fields work? When a document is loaded in your browser, a fingerprint of the document binary is made, and sent to the server. The document table consists of: document_id, fingerprint and created_at. As soon as you start editing a document, a template is created, containing metadata about the fields (x, y, width, height, type of field, background color...) that is then tied to this document you created. Once you save, this template gets sent to the server. The template table consists of: template_id, document_id, fields (the metadata) as well as created_by_customer_id if you're a customer. As a result, someone else on the other side of the world opening the same document will see the fields you positioned already there – you just saved them the 5min it took you to position them. --- # What's the tech stack of SimplePDF? - NextJS on the frontend - Koa with GraphQL on the backend - Postgres (Managed Database on Digital Ocean) - A 10€ droplet on Digital Ocean --- If you have any questions, comments or feedback (good or bad), I'm all ears! --- [1] The assignments my estonian teacher gives me are usually scanned documents that do not have any editable fields in them.

Show HN: Tape It, iOS recording app for musicians Hello HN, Over the last 15 months, two friends and I developed the music recording app we felt we wanted based on our own needs as musicians. It's called Tape It [1] and has just recently hit the Apple App Store [2]. We put a lot of effort into a good UX to help musicians really focus on playing their instrument instead of pretending to be a recording engineer. The app records in stereo on newer iPhones (although that's a premium feature; the free version only records in standard mono audio quality). I would be really grateful for advice from this community on how to best approach marketing. We had a great TechCrunch article covering our launch [3], and we posted it on various music websites. Turns out advertising on Google or Apple Search is a dark art, though. We have some good ideas for developing a good social media presence, but they will take time. Please hit us with feedback, opinions and advice that you think a young ind...
