NotebookLM Data Tables: I Fed It a Messy Spreadsheet
NotebookLM Data Tables promises to turn messy data into clean tables. I tried it with a real messy spreadsheet. The catch is at the input, not the AI.

I checked 5 Canva alternatives and found that the word "free" hides three completely different deals, and only two of them let you design and export without ever making an account. Those two I opened and worked in. The other three keep their editor behind a signup, so I read their pricing, docs, and real user reports instead, because I don't make accounts to test a tool.
This is for anyone who searched "canva alternatives" because Canva's free plan hit a wall, usually the moment the AI features asked for money. By the end you'll know which tools are free forever, which are free behind a login, and which one is a trial wearing a free costume.
Pick Polotno Studio if you want to design one thing right now with zero account, Photopea for real photo editing if you don't mind ads, Penpot if open source and owning your data beat templates, Adobe Express if you want AI image credits that refill every month, and Gamma only if you need one batch of AI slide decks and nothing after. Each wins on a single axis, not on all of them, which is the part the big lists skip.
I split the five into two piles: the ones I could use, and the ones I could only read about. Polotno Studio and Photopea let a logged-out visitor into the full editor, so on July 22, 2026 I opened both and worked in them, reaching the export step with no login. The other three sit behind a signup, and I don't create accounts to test a tool, the same rule we used for the best AI writing tools. For those I read the pricing pages, docs, and real user reports. That's an honest trade: no feel for Penpot's canvas, but an exact read on what each free plan costs you.
Polotno Studio is the only tool here that asks for nothing: no email, no login, no card. I opened studio.polotno.com and landed straight in a working editor with Templates, Text, Draw, a Background remover, and Resize. Its Download menu offered eight formats with no prompt to sign up: JPEG, PNG, PDF, SVG, HTML, GIF, JSON, and MP4, and no watermark on the way out. The one catch: no account means no cloud save, so export the editable JSON before you close the tab. Verdict: 8/10 for anyone who needs one graphic in the next ten minutes; not for teams who want shared brand kits.
Photopea is a full Photoshop in your browser, free and account-free, and it pays for itself with ads. I clicked "Start using Photopea" and the editor loaded with the whole Photoshop menu set and opened PSD, AI, XD, FIG, sketch, PDF, and RAW files. Then a consent box asked me to share my personal data for "personalised advertising" with 685 partners. I didn't expect to meet all of them before drawing a single rectangle. You click "Do not consent" and keep working, which I did; the free tier shows an ad sidebar, and Premium at $5 a month removes it. Verdict: 8/10 as a free photo editor, one point off for the 685 friends; not for anyone who wants Canva-style templates.
Penpot is the open-source answer, and its free tier is the most honest of the login-required bunch. The Professional plan is $0 with no file limits, up to 8 members plus unlimited viewers, 10 GB, and 7-day version history, and being open source you can self-host it for nothing. Paid Unlimited is $7 per user a month. I have to be straight, though: Penpot isn't really a Canva. It's a Figma-style interface-design tool that hands work from designers to developers, generating CSS, HTML, SVG, and JSON from the canvas. Verdict: 7/10 for people who value open source and data control; not for someone who just wants Canva without Canva.
Adobe Express has the one free AI tier in this list that refills every month instead of running dry. Free users get 25 Firefly generative credits a month, and here's the point: they reset. Adobe's own credit docs say they arrive on first use, expire a month later, then arrive again, the opposite of the lifetime-credit trick two other tools here pull. For that money, meaning zero, you also get social templates, thumbnails, and short-video tools. Paid consumer plans run $9.99 to $19.99 a month. Verdict: 7/10 for the honest, resetting free tier; the wall is the Adobe account, which is why I read the docs instead of testing it.
Gamma's free plan is the clearest case in this list of free that's actually a trial. You get 400 credits once, not a monthly allowance, and each AI slide deck eats 4 to 6 credits, so you get roughly 30 to 40 decks total before the AI stops unless you pay. Every free deck also carries a "Made with Gamma" watermark until Plus at $10 a month. Canva plays the same game: its design editor is free forever, but Magic Media video gives free users 5 lifetime credits, total, and Pro at about $15 a month holds the 500-monthly-credit pool. When our roundup of AI tools that are actually free drew a line between free and trial, this is the line it meant, and anyone who hit Midjourney's missing free tier knows the pattern. Verdict: 5/10, because a free tier that can't refill isn't really free.
Lined up side by side, the five sort into three kinds of free.
| Tool | Account? | What "free" gives you | Free AI credits | Paid from |
|---|---|---|---|---|
| Polotno Studio | No | Full editor, 8 export formats | No AI credit meter | SDK is paid |
| Photopea | No | Full photo editor, ad-supported | AI features, with ads | $5/mo |
| Penpot | Yes | Free forever, self-host, 10 GB | No AI credit meter | $7/user/mo |
| Adobe Express | Yes | Templates plus AI | 25/month, resets | $9.99/mo |
| Gamma | Yes | 400 credits, watermark | 400 lifetime, ~30-40 decks | $10/mo |
Match the tool to your one real job, not the longest feature list. Design one thing now with no account: Polotno Studio. Real photo or PSD editing for free: Photopea. Open source and data control: Penpot, if you accept it's a designer's tool. Monthly AI credits that refill: Adobe Express. A one-off batch of decks: Gamma, and stop before month two. Still want Canva's exact templates? Its free design editor stays free, and only the AI costs.
If I had to keep one of these tabs open, it's Polotno Studio, purely because it never once asked me who I was. That's rarer than it should be. Photopea is the one I'd reach for on real work, ads and all, because a free Photoshop in a browser is a good deal. What I can't tell you, and won't pretend to, is how Penpot, Adobe Express, or Gamma feel under your hands, because getting there means making an account and I tested these from the outside. But "free" on a Canva-alternatives list is quietly hiding three different deals, and now you know which is which before you spend an afternoon finding out.
