## Aquin

Aquin is best understood as a research lab rather than a single consumer app. The homepage describes the team as reverse engineering intelligence through interpretability, and frames its goal as applied prediction that compounds over time - systems that understand what a model has learned and that teams can point at their own data. The flagship applied product is Aleph, a universal predictor spanning tables, media, annotation and decisions.\n\nWhat separates Aleph from a general-purpose assistant is its output contract. It produces schema-bound results for programs: probabilities, labels, bounding boxes and scores, each carrying confidence so that uncertain items can be escalated rather than silently guessed. The lab positions this as 'one base, any modality, any task', fine-tuned into a specific workload and improving as more labelled work arrives.\n\nAround that core, Aquin publishes applied research on interpretability. Published work includes an interpreter for attention-as-routing-graph circuits from a single forward pass, tiled SVD methods for locating usable weight mechanisms, agentic weight-editing experiments on small models, and simulations of LLM behaviour in varied environments. Separate projects like the axi self-learning agent and the aq developer environment target people building and refining foundation models.

**Pricing & Plans:** Aquin does not publish a public price list. The site mixes freely readable research with applied engagements, so commercial terms are discussed directly with the team.

- **Universal predictor (Aleph):** A single base that handles tables, media, annotation and decision tasks, with the option to fine-tune toward your specific data.
- **Schema-bound outputs:** Outputs are typed and scored rather than free text, so downstream programs can act on results and escalate low-confidence cases.
- **Interpretability research:** Treats attention as a routing map from a single forward pass, isolating a small subgraph aimed at the answer and testing it under ablation.
- **Weight editing experiments:** Agentic weight-editing experiments that localise causal layers, apply rank-one MLP updates and validate then roll back steps when checks fail.
- **Self-learning developer agent:** An agent for controlling developer environments and running coding or research loops with recorded lessons and rejected paths.

**Strengths:** Research-grade interpretability work published openly alongside the applied product; Outputs designed for programs rather than chat, which suits automation pipelines; Explicit confidence scores make it practical to escalate uncertain predictions; One base is claimed to cover tables, media, annotation and decisions

**Limitations:** Aquin Labs is a research organisation, so most output is papers and interfaces rather than a polished consumer app; Aleph is described as a predictor for programs and teams, not a general chat assistant; No transparent public price list was found for commercial engagements; Material is heavily technical and assumes familiarity with ML evaluation work

## Perplexity Comet

Comet is a standalone web browser built by Perplexity around an AI assistant. Instead of treating AI as a separate site you visit, Comet embeds it in the browsing experience, so the assistant already knows which page you are looking at and can act on it. You can ask about an article you are reading, have a long page summarized, or hand off a task and let the assistant carry it out.

The browser is pitched as a personal assistant that handles more than chat. It can research a topic, draft an email reply that reflects your schedule, build a small website, put together a study plan, compare how different outlets cover a story, or help with shopping. Because it lives in the browser, these tasks run against the real web rather than a sandboxed chat window.

Comet is available for Mac, Windows, iOS, and Android, and can be set as your default browser. It sits within Perplexity's freemium model: you can start free and unlock more advanced AI capability through paid subscription tiers. Privacy and safety controls are managed in the browser settings, and Perplexity publishes guidance on how browsing data is handled.

**Pricing & Plans:** Freemium with paid options. Comet itself is free to download across Mac, Windows, iOS, and Android. Advanced AI capabilities and higher usage limits are tied to Perplexity's paid subscription tiers, which are billed separately.

- **AI that understands the page:** The assistant understands the page you are on, so you can ask follow-up questions and get answers grounded in what you are reading.
- **Agentic task execution:** Delegate tasks like drafting replies, creating study plans, or building a simple website, with the assistant taking actions for you.
- **Cross-platform availability:** Comet runs on Mac, Windows, iOS, and Android, so your browsing and your assistant follow you across devices.
- **Perplexity search built in:** Perplexity's answer engine is built in, so research and web search stay inside the browser instead of a separate tab.
- **Default browser and privacy controls:** Set Comet as your default browser and manage privacy and safety settings as you browse.

**Strengths:** The assistant sees the page you are on, so answers are grounded in your actual context; Handles real tasks like drafting email, building simple artifacts, and research, not just Q&A; Available across desktop and mobile platforms; Brings Perplexity's answer engine into the browser by default

**Limitations:** Requires switching from your current browser to get the full experience; Best features depend on a Perplexity account and subscription tier; Agentic automation is powerful but should be supervised on sensitive tasks
