## AltIndex

AltIndex is an investment research platform built around alternative data — the non-traditional signals that hedge funds and quant desks have long paid heavily for. Instead of relying only on earnings and price history, it continuously measures things like company web traffic, app download estimates, job-posting momentum, Reddit and social chatter, insider transactions and congressional disclosures, then aggregates them into a single 0–100 score per stock.

Those scores feed several tools. Autopilot turns rules-based portfolios into models you can follow automatically; AI Stock Picks surfaces high-conviction long and short candidates drawn from the scoring model; and Stock Alerts push a notification the moment a company you care about spikes in popularity, sentiment or insider activity. A portfolio AI score lets you upload a screenshot of your brokerage and see every holding ranked, making it easy to spot the positions dragging your overall score below 60.

There is also an AI analyst interface that answers plain-English questions about your holdings, grounded in live AltIndex data rather than invented figures, and an MCP server plus API so institutions and developers can pipe the same signals into their own tools. The site also publishes free trending pages — Reddit stocks, congress trading, the Fear & Greed index, earnings calendar — and a regular newsletter with picks and market commentary.

**Pricing & Plans:** Freemium with a free tier and free trial. Searching tickers requires no account, and there is a newsletter promotion offering a discount. Paid plans unlock the fuller Autopilot, AI picks, alerts and institutional/API access; exact tiers are listed on the AltIndex pricing page.

- **Alternative-data signal engine:** Scores stocks using web traffic, app downloads, job postings, social mentions and insider activity rather than price charts alone.
- **AI stock picks and alerts:** High-conviction buy and sell signals plus real-time notifications when a holding spikes in popularity, sentiment or insider trading.
- **Portfolio AI score:** Upload a brokerage screenshot and get a 0–100 score for every holding, blended into a single portfolio score.
- **Ask AltIndex AI:** Ask plain-English questions about your holdings and get answers grounded in live scores, fundamentals and alt-data signals.
- **MCP server and API:** Plug AltIndex data into your own AI assistants, notebooks and internal tools for institutional or personal workflows.

**Strengths:** Blends genuinely differentiated alternative-data signals with standard fundamentals instead of repackaging price data; Portfolio scoring via a brokerage screenshot avoids any account linking or credential sharing; Publishes an MCP server and API, which is rare for retail-focused research platforms; A substantial library of free research pages and a newsletter make it easy to evaluate before paying

**Limitations:** AI stock picks come with no guarantee of future performance; the site cites a 61% win rate that is historical only; Some of the headline features, including Autopilot and institutional data access, sit behind paid plans; Alternative-data signals can be noisy and occasionally contradict the underlying fundamentals

## 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
