# Manus vs Elicit

> Source: https://theagentsindex.com/compare/elicit-vs-manus (structured, researched, re-verified)

Manus and Elicit both plan and execute multi-step research work with little hand-holding, but they point at completely different targets. Manus is a general-purpose autonomous agent from Butterfly Effect (the team behind the Monica assistant): give it a goal in plain language and it spins up its own cloud computer, browses the live web with a browser operator, writes and runs code, and hands back a finished deliverable — a report, a slide deck, or even a small deployable web app. Its "Wide Research" mode fans a broad question out across many parallel sub-agents to cover more ground than a single pass. Elicit does not touch the open web at all. It is a hosted product built specifically for scientific and academic literature: its Research Agent plans sub-questions and searches over 138 million papers, and a dedicated Systematic Review workflow automates the screening step of a formal literature review — up to 5,000 papers on its Pro tier, 40,000 on Enterprise — against inclusion criteria you set, which Elicit's own pricing page describes as "PRISMA-grade accuracy" at the top tier.

Rigor and reliability diverge just as sharply as scope. Every claim Elicit generates carries a sentence-level citation back to the source paper, and its own documentation is upfront that hallucination remains a real risk despite that grounding — it tells users to verify important findings against the original paper rather than trust a summary alone. Manus's citations are only as good as whatever its browser operator finds on the open web, and independent testing has found a sharper problem: the agent can degrade on long, branching workflows and has produced fabricated "verification" output that looked real but described a state that never existed. Manus is best suited to straightforward, mostly read-only jobs — a research summary, a data pull — not mission-critical or write-heavy work; Elicit is built for a narrower job (published literature) but does that job with an auditable, structured process a general web agent has no equivalent of.

Pricing and stability tell the rest of the story. Manus runs on a credit system: a free tier gives a small daily refill (about 300 credits, roughly one task a day), and paid Pro tiers start around $20/month for larger monthly credit pools — but usage is unpredictable, since a single complex job can burn hundreds to well over a thousand credits. Elicit's Basic tier is free for unlimited paper search and chat, with Research Agent and Systematic Review usage capped until Pro ($49/month) or Scale ($169/month); Enterprise is custom. The two companies' footing also differs: Elicit is a public-benefit corporation that has raised $31M total ($9M seed, $22M Series A) with a straightforward ownership structure, while Manus's backing has been genuinely unsettled — Meta closed a roughly $2B acquisition of Butterfly Effect in December 2025, Chinese regulators ordered it unwound in April 2026, and a Tencent-led buyback was still being negotiated as of July 2026 with no confirmed close date.

## Verdict

Need an agent that autonomously browses the open web, writes code and ships a finished deliverable — a report, a deck, a small app — without being scoped to any one domain → Manus. Need cited, structured evidence pulled specifically from published scientific literature, especially a formal systematic review with auditable screening at PRISMA-grade rigor → Elicit. Doing mission-critical or write-heavy work where an unnoticed error is expensive → treat both cautiously, but note Elicit self-discloses its hallucination risk and scopes itself to a narrower, more checkable domain, while Manus has been caught fabricating convincing-looking verification output on complex tasks. Want predictable pricing → neither is fully predictable, but Elicit's tiered subscription caps are easier to budget against than Manus's per-action credit burn.

## FAQ

**Is Manus or Elicit free?**

Both have real free tiers. Manus gives a small daily credit refill (about 300 credits, roughly one task a day) with no card required; paid Pro tiers start around $20/month for larger credit pools. Elicit's Basic tier is free for unlimited paper search, summaries and chat, but Research Agent and Systematic Review usage is capped until you upgrade to Pro ($49/mo) or Scale ($169/mo).

**Which one can search academic papers?**

Elicit — it searches over 138 million scientific papers and extracts sentence-cited, structured data from them. Manus researches the open web through a browser operator; it isn't scoped to an academic paper index and has no systematic-review screening workflow.

**Can either one do more than research — like build something?**

Manus can: beyond research, it writes and runs code, and can assemble and deploy real deliverables such as slide decks or small web apps. Elicit is scoped entirely to literature search, review and data extraction — it does not build or deploy software.

**How reliable are Manus and Elicit?**

Elicit self-discloses hallucination risk in its own documentation and recommends verifying important findings against the source paper, but its claims carry sentence-level citations and it is scoped to a checkable domain. Manus has been caught by independent testers producing fabricated "verification" output that looked real, and it degrades on long, branching workflows — treat both as needing human verification, but Manus carries the higher-stakes failure mode on complex tasks.

**Which company is more stable to build on?**

Elicit is a public-benefit corporation with a straightforward funding history ($31M total: a $9M seed and $22M Series A). Manus's ownership has been genuinely unsettled: Meta closed a roughly $2B acquisition of parent company Butterfly Effect in December 2025, Chinese regulators ordered the deal unwound in April 2026 on national-security grounds, and a Tencent-led buyback was still being negotiated as of July 2026 with no confirmed close date.
