AI tools for researchers
AI tools for researchers
Create a free account and you get 25 credits to start — then everything runs pay-as-you-go, with no subscription. Four tools cover the pre-submission core — Pre-Check (acceptance-probability scoring), Gaps & Literature Search, the Journal Finder, and the Duplicate Publication Checker — and two more are everyday, browser-only utilities: a Citation Generator and a Graphical Abstract Maker. One heavier tool spends more credits: AI Review. This page is the honest index — what each tool does, what it costs in credits, and which one you actually need for the stage you're at.
The low-credit tools
Three tools cover the pre-submission stage of a paper — scoring, scoping, and journal selection — for 15 credits a run; the duplicate-publication check and two browser-only utilities are free. Create a free account and you get 25 credits to start:
- Pre-Check — paste a title + abstract, get a calibrated Tier 1-5 acceptance probability, the detected field, and a ranked target-journal shortlist in under a second. Runs on a local 4.5M-paper library. 15 credits per run. → /pre-check
- Gaps & Literature Search — search any topic to surface the open research questions in that field, mined from 100,000+ papers and the 250M-work OpenAlex graph. 120,000+ open gaps pre-indexed. 15 credits per run. → /research-gaps
- Journal Finder — paste a title + abstract for a ranked shortlist of target journals from a 17,500-venue index, each with tier, open-access status, citation rate, publisher, and a predatory-journal flag. 15 credits per run. → /journal-recommender
- Duplicate Publication Checker — cross-references your title + abstract against CrossRef, arXiv, medRxiv, bioRxiv, Unpaywall, and a 4.4-million-paper library in ~30 seconds to flag prior-publication and salami-slicing risk. Bundled into Pre-Check. → /duplicate-publication-checker
- Citation Generator — paste a DOI or title and get a formatted citation in APA, MLA, Vancouver, and Chicago, plus BibTeX and RIS for Zotero/Mendeley/EndNote. Metadata from CrossRef + OpenAlex, deterministic, runs in your browser — free, nothing stored. → /cite
- Graphical Abstract Maker — turn a title and 1-4 key findings into a clean, colorblind-safe graphical abstract, downloadable as vector SVG or 2000×1200 PNG, entirely in your browser — free, nothing uploaded. → /graphical-abstract
The heavier tool
One tool involves real LLM cost on every run, so it spends more credits. It is explicitly cheaper than the alternatives it replaces:
- AI Review — upload a full manuscript PDF and 8 specialist agents return a structured editorial decision with line-level revision suggestions in under 15 minutes. 30 credits per review. → /ai-review
Which tool do I need?
A quick decision guide by where you are in the research cycle:
- Starting a new project, looking for a question → Gaps & Literature Search (15 credits).
- Have a draft, wondering if it's ready → Pre-Check (15 credits) for the Tier verdict.
- Draft is solid, deciding where to submit → Journal Finder (15 credits).
- Worried about prior-publication or salami-slicing overlap → Duplicate Publication Checker (bundled into Pre-Check).
- Need to format a reference fast from a DOI → Citation Generator (free, in your browser).
- Journal wants a graphical or visual abstract → Graphical Abstract Maker (free, in your browser).
- Want a full, calibrated peer-review report before you submit → AI Review (30 credits).
Why credits, and why they're cheap
It's a deliberate model, not a trial gimmick. The pre-submission tools — Pre-Check, Gaps & Literature Search, the Journal Finder, and the Duplicate Publication Checker — run on local indexes rather than expensive LLM calls, so we can price them at 15 credits a run. The Citation Generator and Graphical Abstract Maker run entirely in your browser, so those stay free. Creating an account is free and starts you with 25 credits, enough to run one on your draft.
The heavier tool — AI Review — carries real per-run LLM cost, so it spends more credits. Everything is pay-as-you-go: buy credits in one-time packs, and they never expire. No subscription, no rate-limit games, no upsell baked into the tool itself.
