AI Bookmarks Opens a Free Tools Section: 8 Free Utilities for Work AI Skips

aibookmarks.net has spent its first year cataloguing AI tools, and almost every one of them is paid in some way: a subscription, a credit pack, or a free trial that quietly converts. Today the directory opens a section that runs the other direction. Free Tools collects eight utilities that cost nothing in the plain sense of the word — no card, no trial clock, and in most cases no account at all.

The reason is straightforward. A large share of the work people bring to an AI tool does not need a model. Merging a PDF, converting a video container, producing an email signature, finding the official installer for an open-source application: these were solved problems a decade ago. Paying a monthly fee for them is waste, and for anyone who will not put a card on file, it is a wall. The new section lives at aibookmarks.net/category/free-tools and is organised by the job rather than by launch date.

What “AI for everyone” usually misses

The argument that access to AI should not depend on budget — AI pingquan, if you prefer the Chinese framing — is normally discussed in terms of models: open weights, cheaper tokens, free chatbots. All of that matters. But the barrier most people actually hit is duller than that. It is the ring of small paid utilities around the model: the PDF converter that wants $9 a month, the video converter with a 100 MB ceiling and a watermark, the signature builder that asks for a work email before it shows you the HTML.

Every AI directory shares one blind spot, and it is structural rather than lazy. Tools get catalogued because they launch, raise money and buy attention. A free utility that has worked quietly for ten years does none of those things, so the reader who needs to convert forty files ends up on a pricing page instead. Free Tools is meant to correct that bias, and it is the one category on the site where every entry's listed price starts at Free.

The eight tools, by the job they do

Each heading below links to the tool's page in the directory. Those pages carry the full write-up: what the tool does with your file, what it costs, which platforms it runs on, and where the ceiling is.

1. Tool Cabana — free PDF, image and text utilities, no account

A directory of small browser tools rather than a single product. One page handles PDF work: converting to and from Word, Excel and PowerPoint, merging, splitting, compressing, watermarking, signing, and OCR on scans. Another covers images, with compression, cropping and format changes. Around them sit a QR code generator, a JSON formatter and an internet speed test. Most text, calculation and document operations run in your browser, and any step that needs a server says so before you submit a file. No account, no paid tier, no workflow builder — it is built for one-off jobs. Full write-up on Tool Cabana.

2. PDF24 Tools — the PDF suite you would otherwise subscribe to

A long-running German project with two faces. The web tools need no installation: convert, merge, split, rotate, compress, add page numbers, fill and flatten forms, extract text and images, run OCR on scans. PDF24 Creator is a free Windows application that bundles the same toolset with a virtual PDF printer and works offline, so sensitive documents never leave the machine. Advertising pays for the web version, which is why there are no caps, no watermarks and no paid edition to compare against. Full write-up on PDF24 Tools.

3. Signature — an email signature as copy-paste HTML

HubSpot's free generator builds a signature from a short form and hands you the HTML to paste into Gmail, Outlook or Apple Mail. No account, no card, no email gate before the export. The useful difference is the output: markup you own rather than a flat image, which means it stays editable and keeps rendering as plain text on clients that refuse images. Full write-up on Signature.

4. Read papers — arXiv triage with an AI FAQ on every paper

The most AI-native of the eight. papers.cool lists each day's arXiv submissions one category at a time and attaches an AI-generated FAQ to every paper, so you can decide in seconds whether an abstract deserves a full read. Browsing, PDF preview and the FAQ are free with no registration. For anyone tracking a fast-moving field it replaces the routine of opening twenty tabs to find two useful papers. Full write-up on Read papers.

5. Logo design — a brand name in, usable marks out

A Chinese generator that turns a typed brand name into finished logo marks you can download free, with no credit line and, according to the site, no download limit. Read it as a placeholder machine: it gets a side project or a small business to something credible in ten minutes, and it is a cheap way to see several rough directions before paying a designer. The output is raster artwork, not a layered design file, so it does not scale into a brand system. Full write-up on Logo design.

6. Software download — the publisher's page, not a mirror

FOSSHub keeps a hand-maintained catalogue of free and open-source applications and sends you to the publisher's own download page instead of hosting a copy. That distinction is the entire point: download portals that wrap open-source installers in adware are still the default result for a lot of searches, and checking which version a project last published is a normal thing to need. Free to browse, no account, no paid listings. Full write-up on Software download.

7. Format converter — 262 formats, with the limits published

AConvert handles documents, images, video, audio and archives across 262 formats in the browser, with per-category size ceilings stated on the page rather than discovered at the upload button. No PRO tier, no per-file charge, no account. It is the right answer for the one-off conversion that does not justify installing a converter — and the honest limit is the reason it is in this section at all. Full write-up on Format converter.

8. Agent plans — the one that points back at AI

A free quiz that asks what you actually want automated, then names the first job worth handing to an AI agent and gives you a prompt to run it with your own bot. Full result and prompts without signing up; the paid tier is optional. It sits in Free Tools because the entry price is zero, not because the whole product is — the prompts assume you already pay for an agent somewhere. Full write-up on Agent plans.

What free does not mean

Every entry states its ceiling, and none of those ceilings is hidden behind a paywall:

• Several of them upload your file. Tool Cabana and PDF24 keep most operations local, but the steps that need a server still send the document somewhere. Do not assume otherwise.
• There are no APIs anywhere. Nothing in this section fits a scripted pipeline. These are interfaces for a person doing one job at a time, and if you need batch automation none of the eight is the answer.
• PDF24 Creator is Windows only. Mac and Linux users get the web version, with the advertising that pays for it.
• Advertising is the price of PDF24's web tools, and it appears on every tool page rather than in one corner.
• The logo generator gives you images, not a brand system. Raster marks are fine for a placeholder and wrong for anything that has to scale.
• Free can mean free to browse. FOSSHub is a catalogue; the software it links to carries its own licence, and some of those are copyleft. Check before you ship it inside a product.

All eight now sit on one page: aibookmarks.net/category/free-tools. Each entry lists what the tool does with your file, what it costs, which platforms it runs on and where the limit is, which is the pattern the rest of the directory follows. aibookmarks.net is a human-curated AI tool directory (one of the most comprehensive AI tool directories), and it sorts tools by the job you need done rather than by who raised the most recent round. Comparisons, category pages and buying guides sit alongside the listings, so a decision can be reached in one place instead of across a dozen leaderboards.

The part that is actually about access

Free software has always been a form of redistribution, but the argument here is smaller than ideology. If the utilities around the model cost nothing, then the only thing between a person and useful work is the work itself. That is a more defensible version of “AI for everyone” than a discount code, and it is also just good engineering: pay for the model that earns its subscription, stop paying for the problems that were solved before the model existed.

The section is open for additions. If you run a free or open-source tool that belongs in it, or you use one that has already saved you a subscription, the contact form is the place to say so. Entries are checked by hand on three questions — what it does with your file, what it costs, where the ceiling is — and a tool that cannot answer all three does not go in.
