## Jack and Jill

Jack and Jill reframes hiring as a matching problem solved by AI agents on both sides of the market. For candidates, Jack scans large volumes of job listings daily to surface roles that fit a person's actual goals rather than keyword overlap, and it coaches on career clarity, mock interviews and salary negotiation. For companies, Jill automates candidate sourcing and screening, surfacing people who might otherwise be missed. The two agents coordinate, and when mutual interest exists they introduce the parties directly, skipping the usual application stage.

The platform is designed to sit lightly on top of existing workflows. Hiring teams can reach candidates through the usual channels including Slack and email, connect Jill to their applicant tracking system, and use public profile search to widen reach. Candidates get a conversational experience: they talk to Jack, receive matched roles and early interview feedback with notes on answer quality and what to improve.

The economics are unusual for recruiting: Jack is free for job seekers, and the company pays only when a hire actually happens, so the incentive aligns with outcomes rather than subscriptions. Because features, coverage and pricing terms evolve, check the official site for the current details.

**Pricing & Plans:** Free for candidates. Companies pay, structured around successful hires rather than seat subscriptions. Specific terms are confirmed through contact with the Jack and Jill team, so check the official pricing page for the current model.

- **Jack, the AI career agent:** Scans millions of jobs daily to surface roles matched to a candidate's goals, not just keywords, and guides career decisions.
- **Jill, the AI hiring agent:** Automates candidate sourcing and screening for hiring teams, surfacing relevant profiles from public sources and networks.
- **Direct introductions:** When there is mutual fit, Jack and Jill introduce candidate and company directly, bypassing the traditional application pile.
- **Interview and negotiation coaching:** Jack runs mock interviews with feedback on answer quality and helps candidates understand their value and negotiate offers.
- **Workflow integrations:** Hiring teams can connect Jill to ATS and reach candidates via Slack, email and other existing channels.

**Strengths:** Free for candidates, with the company paying on successful hires; Agents on both sides of the market improve match quality; Direct introductions skip the traditional application pile; Includes interview prep, salary negotiation and biosignals on answer quality

**Limitations:** Value depends on having strong coverage in your industry and region; Company-side pricing is not openly published and requires contact; Direct-introduction model means fewer but more curated opportunities rather than many applications

## Models.dev

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

**Pricing & Plans:** Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

**Strengths:** Free and open source with no account required; Consistent canonical identifiers make cross-provider comparison reliable; Covers pricing, limits, and capabilities in one sortable table; Available as a JSON API and type-safe SDK for programmatic use

**Limitations:** It is a reference catalogue, not an inference or hosting service; Data quality depends on community and maintainer updates keeping pace with releases; Interface is aimed at developers and offers little guidance for non-technical users
