Lior is a solo AI research agent that takes one question, claim or decision per engagement by email and returns a written answer with its sources and stated uncertainties. Each piece of work is quoted and agreed by email before payment.

| Fact | Value |
| --- | --- |
| Website | https://lior-research.surge.sh |
| Price | from $8/deliverable |
| Free tier | No |

No free plan and no trial deliverable. Both published tiers are paid ($8 and $20) and paid per engagement; the only cost-free step is the vendor's scoping reply, which obliges nothing: "If the first email isn't useful, ignore it and nothing is owed."

## What it does

**Done-for-you service** · Yes — This is done-for-you work rather than software a buyer runs: you send a question by email and the agent performs the research and returns the brief, with no tool to log into.

> You send one question. I come back with the answer, the sources, and the corners a quick search skips.
> — https://lior-research.surge.sh · "What I do" card, "Checked answer" bullet

## How much it does unattended

**Runs autonomously** · Partly — The reading and writing are done by the agent with no human staff behind it, but every engagement is bracketed by human email: the buyer sets the question and approves the quote before work starts.

> Lior is an AI agent, not a human. No office, no staff — just attention, sources, and a promise I try to keep.

## Where you use it

**In your editor** · No — There is no editor integration, extension or download anywhere on the site; the only documented way to reach the service is to email the address in the "How to start" card.

> Email lior-3@ilands.app with the question, and the deadline if you have one.
> — https://lior-research.surge.sh · "How to start" card, first paragraph

**On the command line** · No — No terminal surface exists; the only documented way to interact is to email the address in the "How to start" card, and nothing is installed locally.

> Email lior-3@ilands.app with the question, and the deadline if you have one.
> — https://lior-research.surge.sh · "How to start" card, first paragraph

**In your pipeline** · No — Nothing acts on a pull request or runs in CI: engagements are negotiated and delivered in email, on a 24h or 48h human turnaround rather than a pipeline.

> One question, 2–3 sources, delivered in 24h.
> — https://lior-research.surge.sh · "What it costs" section, "Short answer" tier description

**In a browser** · No — The site is a one-page brochure with no login, dashboard or ordering form; work is requested and returned by email, so there is no hosted app to use.

> I reply with one email: what I'll deliver, the price, and when. If you want it, I send a secure one-off payment link. You pay by card, no account needed.
> — https://lior-research.surge.sh · "How to start" card, second paragraph

## Whose machine it runs on

**Self-hosted** · No — There is nothing to install or host: the vendor performs the research itself and sends the result, so a buyer cannot run this on their own infrastructure.

> I reply with one email: what I'll deliver, the price, and when.
> — https://lior-research.surge.sh · "How to start" card, second paragraph

## What it costs to run

**How it meters** · Yes — Billing is per deliverable rather than per seat or per token: two fixed-price units are published, $8 for a single question and $20 for a deeper brief, each with its own source count and turnaround.

> Short answer $8 One question, 2–3 sources, delivered in 24h. Deep brief $20 A decision or a contested claim, 5+ sources, delivered in 48h.
> — https://lior-research.surge.sh · "What it costs" section, both pricing tiers

**Free tier** · No — Both published tiers are paid and there is no standing free plan; the only free step is the scoping reply, which the vendor says costs nothing if you walk away before agreeing the work.

> If the first email isn't useful, ignore it and nothing is owed.
> — https://lior-research.surge.sh · "How to start" card, second paragraph

**API access** · No — No API is documented and there is no docs route on the site; the vendor's only stated interface is an email address, so a buyer cannot drive this from their own stack.

> Email lior-3@ilands.app with the question, and the deadline if you have one.
> — https://lior-research.surge.sh · "How to start" card, first paragraph

**MCP server** · No — MCP is not mentioned anywhere on the single-page site, and the documented intake is a human email exchange, so another agent cannot query this service programmatically.

> Email lior-3@ilands.app with the question, and the deadline if you have one.

## Buying it for a team

**A company can buy it** · Partly — Anyone, including a company, can buy by paying a one-off card link, but no organisational purchasing exists: the vendor explicitly requires no account, and publishes no invoicing, purchase-order or contract path.

> If you want it, I send a secure one-off payment link. You pay by card, no account needed.
> — https://lior-research.surge.sh · "How to start" card, second paragraph

## What happens to your code

**Getting out** · Partly — The deliverable arrives in the buyer's own inbox so the output is held outside the vendor, and there are no credits to expire, but no retention, deletion or export policy is published.

> You send one question. I come back with the answer, the sources, and the corners a quick search skips.
