> I just caught GPT-4 totally hallucinating DOI links for my urban planning dissertation and now I dont trust anything. ^ This. Also, GPT is basically a giant hallucination machine when it comes to metadata. It just predicts what a DOI should look like based on patterns, which is totally useless for a dissertation. Since youre on a tight $30 budget, you might want to consider Scite.ai Assistant Monthly Subscription instead of the generic bots. It has an Assistant feature that specifically uses its own database of over a billion citation statements to verify claims. It actually tells you if a paper was supported or contradicted by others, which is gold for your lit review. I would suggest being careful with any automated tool, but Scite is way more grounded in real data. If you really need to save your money, definitely grab ResearchRabbit AI Research Discovery Tool. Its totally free and lets you visualize citation networks specifically for stuff like urban planning. It wont fetch every single paywalled PDF—nothing really does that legally except your school library—but it gives you solid BibTeX exports that wont fail a manual check. Make sure to pair these with Zotero 7 Reference Manager Software for your local library. You can dump everything there to stay organized for that final three-week push. If you use the free ResearchRabbit for discovery and the $20 Scite sub for verification, you stay well under your budget and your grade stays safe. Honestly, stop using GPT for citations immediately... its just gonna keep breaking your heart.

TL;DR: Scite.ai Premium Monthly Subscription is better for vetting citations, but ResearchRabbit AI Discovery Tool is free and maps papers visually. Im happy with both tho...

Honestly, stop using generic LLMs for citations. GPT-4 is notorious for faking sources. Ive been using Elicit AI Research Assistant Plus for my literature reviews lately and its way more reliable because it actually searches the Semantic Scholar database. Another solid bet is Consensus AI Search Premium which focuses on peer-reviewed results. They both handle BibTeX much better and rarely make up DOIs. Both stay under your budget too.

Saw your post earlier and figured Id chime in. Check out SciSpace Premium Academic Subscription. Its way safer for a dissertation because it searches real databases instead of just guessing. It handles citations and BibTeX properly and costs about 20 bucks. TL;DR: Use SciSpace. It actually verifies sources so you dont get stuck with fake DOIs right before your deadline.
