## Captide

Captide is an enterprise-grade API platform built for investment research workflows. It collects public companies' filings, earnings call transcripts, press releases and proxy statements from around the world, cleans the material into structured Markdown designed for LLM consumption, and makes it available through documented APIs. Instead of building and maintaining document-gathering, OCR and parsing pipelines, customers call Captide endpoints to pull filings or to ask grounded questions.

The platform pairs a documents API with an agent-response API. The agent-response layer powers multi-agent workflows, qualitative enrichment of equity models and real-time corporate event tracking, with every answer traceable to the sentence level in the source filing so results remain auditable. The company states its data comes exclusively from primary documents, and its audience is primarily long/short hedge funds and investment banks.

The typical path to adoption is booking a demo or requesting an API key. The public marketing describes coverage that spans 10-K and 10-Q reports, 8-K filings, earnings call transcripts, 6-K and 20-F reports, and DEF 14A proxy statements, positioning the product as research infrastructure rather than a single-purpose answering bot.

**Pricing & Plans:** Pricing is not published publicly. Captide directs prospective customers to book a demo or request an API key, indicating enterprise/custom pricing negotiated by usage and coverage.

- **Documents API:** Retrieve global corporate disclosures in clean, structured Markdown built for LLM use and downstream analysis.
- **Agent-response API:** Ask natural-language questions across filings, earnings calls and proxies and receive answers grounded in primary documents.
- **Sentence-level traceability:** Every generated answer links back to its source sentence for auditability and verification.
- **Global filings coverage:** 10-K, 10-Q, 8-K, 6-K, 20-F, DEF 14A proxies and earnings call transcripts from public companies worldwide.
- **Agentic enrichment for models:** Feed qualitative insights and real-time corporate event data into multi-agent workflows and equity valuation models.

**Strengths:** Answers are sourced exclusively from primary documents with sentence-level citations; Removes the need to build and maintain document gathering and OCR pipelines; Covers global disclosures, not just US SEC filings; Purpose-built APIs for multi-agent and analytical workflows

**Limitations:** No public self-serve pricing or free tier; Requires sales contact and an API key before you can evaluate it; Oriented to institutional finance users, so it may be overkill for casual research

## Spark Mail

Spark Mail is a smart email client built to reduce information overload. Instead of treating every message the same, it separates what matters from what can wait: Priority flags emails from important contacts, Group by Sender bundles messages, and dedicated Newsletter and Notification inboxes keep automated mail out of your main view. Tools like Gatekeeper, Snooze, Send Later, Set Aside, and Reminders round out the workflow.

AI is woven throughout the experience. An AI Assistant can find, summarize, and act on anything in your inbox; Spark's writing assistant helps you compose better emails faster; Auto-Drafts prepares replies in advance; and built-in translation and summary features help you handle long or multilingual threads. Calendar and meeting notes support keeps scheduling connected to your mail.

Spark is cross-platform — iOS, macOS, Windows, Android, and web — and syncs accounts across devices, supporting IMAP, iCloud, Exchange, Outlook, Yahoo, and Google. It is well established, cited as an Apple Editors' Choice app with more than 21 million users, and offers both personal and team-oriented plans. For teams, it adds shared drafts, private comments, assignment of email ownership, and progress tracking.

**Pricing & Plans:** Freemium with a free tier and paid individual and team plans; a free trial is available so you can evaluate the premium AI and collaboration features before subscribing.

- **Smart Inbox and Priority:** Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
- **AI writing and assistant:** An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
- **Translation and summaries:** Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
- **Team collaboration:** Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.
- **Focus and scheduling tools:** Gatekeeper blocks unwanted senders, while Snooze, Send Later, Set Aside, and Reminders help you manage time and follow-ups.

**Strengths:** Consolidates multiple email providers in one inbox; Strong AI and focus features that cut through clutter; Robust team collaboration and cross-platform sync

**Limitations:** Full team features require a paid plan; Some AI features are tied to newer Spark versions; Advanced automations have a learning curve
