## Glean

Glean addresses a problem most enterprises hit after their first wave of AI adoption: models are powerful but isolated from the context of the business. The platform builds an enterprise context layer by indexing and understanding content across the tools a company already runs on, then uses that grounding to improve both answer quality and efficiency. Because fewer irrelevant tokens need to be sent to a model, the same question costs less to serve.

The product surface spans four areas: enterprise search, an AI assistant for everyday work, an agent platform for automating long-running processes, and Glean Protect for security and governance. Administrators also get model routing and an AI gateway, letting them decide which models handle which requests without rebuilding integrations. Everything inherits the access permissions of the source systems, so answers stay within each employee's existing rights.

Glean serves large organisations across finance, healthcare, retail, technology, and government, with published customers including Booking.com, Zillow, and Ericsson. It holds SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR, and TX-RAMP Level 2 attestations, and reports 275+ connectors, 40+ supported language models, and 99.9%+ uptime on core services.

**Pricing & Plans:** Contact for pricing. Glean is licensed to organisations based on seats, connectors, and deployment scope, and is evaluated through a demo rather than self-serve purchase.

- **Permission-aware enterprise search:** Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
- **Agent builder and orchestration:** Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
- **Model routing and AI gateway:** Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
- **Grounded content and analysis:** Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
- **Governance and observability:** Administrators get usage controls, spend visibility, audit logging, and compliance-ready governance for every AI interaction.

**Strengths:** Answers cite source systems and inherit their permissions, which removes the main blocker to enterprise-wide rollout; One platform covers search, assistant, and agents instead of three separate vendors; Model routing and token efficiency directly reduce the cost per AI query at scale; 275+ pre-built connectors shorten integration work considerably

**Limitations:** Enterprise pricing is quote-based, so budget planning requires a sales conversation; Full value depends on connecting many internal data sources, which takes IT effort; Smallest teams may find the platform more than they need

## Letterly

Letterly is built for people who would rather talk than type. You open the app and record, or speak directly into Gmail, Slack or Notion through the system dictation layer, and Letterly returns polished text matched to the format you need — a message, an email, a note, a journal entry or a social post. Rewrites are handled by AI: pick a ready-made style such as a formal email or a concise meeting recap, or describe your own format and reuse it later.

Longer recordings get more structure. Letterly handles talks up to about 90 minutes and can split a meeting or lecture transcript by speaker, then produce a summary alongside the full text. Recordings and rewrites are unlimited on the platform, audio and video files can be uploaded for transcription from any device, and notes can be searched by keyword or organized with tags. Offline recording means ideas captured without a connection still arrive in your library.

Letterly is available as a native app for iOS, Android, macOS and Windows plus a web client, with sync across devices. It connects outward too: translations into 90+ languages, text replacements for frequently used phrases, custom vocabularies, Zapier and webhook integrations, Apple Watch recording, and an MCP server that lets assistants like Claude or ChatGPT read and manage your notes. The company states that user content is not used to train AI models.

**Pricing & Plans:** Letterly is free to start with a freemium model. The free tier covers everyday dictation, while paid plans unlock higher usage limits and advanced features; pricing is shown in-app and on the website.

- **Dictate into any app:** Speak inside Gmail, Slack, Notion or any other text field and have clean text appear where you were typing, instead of switching apps.
- **AI rewrites and styles:** Convert raw speech into notes, emails, posts or meeting summaries using ready-made styles or your own saved formats.
- **Meeting and lecture transcripts:** Record up to around 90 minutes, get a transcript split by speaker, and generate a summary alongside the full text.
- **90+ languages with auto-detect:** Language detection happens automatically as you speak, and you can switch mid-sentence without changing settings.
- **Cross-device sync and integrations:** Native apps for iOS, Android, macOS and Windows plus web, with offline recording, translation, Zapier and webhooks, and an MCP connection for AI assistants.

**Strengths:** Works as both a dedicated app and a dictation layer inside tools you already use; Handles long recordings and separates speakers, which basic dictation tools often cannot; 90+ languages with automatic detection and mid-sentence switching; Available on iOS, Android, macOS, Windows and web with sync, plus offline recording

**Limitations:** Voice-first workflow is less convenient in shared or noisy environments; Free tier has usage limits, so heavy dictation requires a paid plan; Accuracy still depends on microphone quality and background noise
