## Logically (formerly Afforai)

Logically, the product that used to be sold as Afforai, is an AI research assistant built around a personal library of documents. You add papers, PDFs, web pages and notes to a workspace, then query the whole collection in natural language. Answers are grounded in your own sources and surfaced alongside the passages they came from, so you can verify a claim before you use it instead of trusting a black-box summary.

The tool has grown into a wider writing and citation environment. Beyond chatting with files, it supports literature review workflows, PDF annotation, note-taking, outlines and drafting, with citation styles handled automatically. That makes it a good fit for students, academics and analysts who juggle dozens of references and need their writing to be traceable back to primary sources.

The Afforai brand was retired in favour of the Logically name, and the old domain now forwards to logically.app. Access to the service is subscription-based with a free tier that requires no credit card, and higher plans unlock unlimited storage and access to more advanced and reasoning AI models.

**Pricing & Plans:** Free plan available with no credit card required. Paid tiers add unlimited storage, unlimited AI usage and access to advanced/reasoning models. 30-day money-back guarantee on upgrades.

- **Chat with your documents:** Ask questions across a whole library of PDFs, papers and web pages and get answers grounded in the passages they came from.
- **Citation-backed writing:** Draft essays, reports and papers where sources are linked and citation styles are handled automatically.
- **PDF annotation and notes:** Highlight, annotate and take structured notes inside documents so your reading turns into reusable material.
- **Literature review workspace:** Organise references, compare findings across sources and build a review outline from a single collection.
- **Multiple advanced AI models:** Premium plans unlock stronger and reasoning-capable models for tougher synthesis and analysis tasks.

**Strengths:** Answers are grounded in your own uploaded sources rather than generic web knowledge; Combines reading, note-taking, citing and drafting in one workspace; Free tier available without a credit card; Upgrades are covered by a 30-day money-back guarantee

**Limitations:** New brand name means the old Afforai identity can still cause confusion when searching; Advanced models and unlimited usage sit behind paid tiers; Best results depend on the quality of the sources you feed it

## Paperguide

Paperguide has evolved from a general-purpose "chat with your PDF" study assistant into a research platform aimed squarely at rigorous evidence work. Its current centrepiece is Systematic Review: you define a protocol, run a documented search, screen abstracts and full texts with per-criterion evidence prepared by AI, resolve conflicts between two independent reviewers, and finish with verified extraction tables plus a PRISMA flow diagram generated from your own counts. The design principle is that AI prepares evidence but never casts the decisive vote — every screening call, extracted value and synthesized claim is traceable to a named source statement and a human verifier.

The rest of the product supports that workflow from the front end. AI Search answers plain-language research questions across more than 200 million peer-reviewed papers with each assertion linked to its source; the Reference Manager imports from Zotero or Mendeley, adds papers by DOI and fetches open-access PDFs automatically; Extract Data turns a stack of PDFs into a structured, cited comparison table you can export to CSV or Excel; and the Research Agent handles multi-step literature reviews up to 50 papers, organized by theme.

Paperguide also ships an AI Writer for citation-grounded drafting, an MCP integration, and a plagiarism checker, with shared team workspaces that keep papers, annotations and reviews attached to the project rather than to one person's account. It is used by academic researchers along with medical device, HEOR, pharma and government policy teams, and reports over one million researchers on the platform. Pricing runs from a free tier through Plus, Pro, Evidence Teams and custom Enterprise plans billed per seat annually.

**Pricing & Plans:** Freemium with a free plan (1,500 AI credits per month plus limited agents and reference manager) and paid per-seat tiers billed annually: Plus around $12/seat/month, Pro around $29/seat/month, Evidence Teams around $89/seat/month with dual-reviewer screening, and custom Enterprise pricing. Yearly billing advertises savings up to 41%.

- **AI Search over 200M+ papers:** Ask a research question in plain language and get a synthesized answer drawn from PubMed, arXiv, OpenAlex and Semantic Scholar, with every claim linked to its source paper.
- **Auditable Systematic Review:** Run PRISMA-style reviews with a predefined protocol, recorded screening decisions, dual independent reviewers and a conflict resolver, and a PRISMA diagram generated from your actual counts.
- **AI-native Reference Manager:** Import from Zotero or Mendeley, add papers by DOI, and get metadata and open-access PDFs fetched automatically, with annotations and notes that feed every other workflow.
- **Cited data extraction tables:** Define custom extraction columns and have AI fill them across many papers, with each value linking back to the sentence it came from, exportable to CSV or Excel.
- **Citation-grounded AI Writer:** Draft from your own library and 200M+ papers in the same document, switching between 1,000+ citation styles without manual reformatting and without invented references.

**Strengths:** Statement-level traceability: click any claim to land on the exact source sentence; Combines search, reference management, extraction and writing in one workspace; Per-criterion evidence speeds up abstract screening and improves reviewer consistency; Free tier is genuinely usable, and annual billing discounts are generous

**Limitations:** Credit-based limits can be reached quickly on heavy research-agent usage; The advanced systematic review features and dual review sit behind the pricier team tiers; It is primarily English-oriented, which may suit non-English primary research less well; Newer compliance certifications such as SOC 2 and ISO 27001 are still listed as coming soon
