SumizAI vs Foresty

What Foresty is

What Foresty is

Foresty is an India-based AI email assistant for Gmail and Outlook that helps draft, reply, follow up, and improve emails instantly — without leaving your inbox. Instead of switching between an email client and a separate AI tool, copying text back and forth, a user works with Foresty right inside the interface they already use daily to manage correspondence.

A freemium model lets people try core functionality for free, while a paid subscription unlocks more advanced features, like tracking threads needing a follow-up or deeper tone analysis. Integrating with both Gmail and Outlook, the two dominant corporate and personal email clients, makes Foresty a realistic option regardless of which email ecosystem a given company or individual uses.

The follow-up reminder feature addresses a common inbox-overload problem — important emails get lost in the daily flood of correspondence, and Foresty helps ensure key threads don't get accidentally forgotten, which can be especially costly in a business context, where failing to reply in time can mean a lost opportunity.

A professional handling heavy business correspondence with many clients at once, using Foresty to polish email tone and style, gradually develops proven response templates for the most commonly recurring types of inquiries. Without saving those templates separately from the inbox itself, it's hard to quickly find and reuse them when a similar inquiry comes in from a different client months later.

SumizAI complements Foresty exactly at that point: proven response templates and observations about which tone works best with specific clients can be saved as ai notes in a local Markdown file, independent of the inbox itself. Someone handling correspondence for several projects at once ends up with a library of proven templates gathered into ai notes, ready to quickly adapt instead of writing every response from scratch.

These tools complement each other: Foresty helps write and improve emails right inside the inbox, while SumizAI ensures proven templates and observations about effective communication survive as ai notes independent of any single email platform.

Someone working in Gmail for one project and Outlook for another at the same time especially appreciates these notes as a shared, platform-independent place to store proven templates and observations — Foresty works great inside a specific email client, but it doesn't carry knowledge between two different inboxes, whereas a note file saved locally stays accessible regardless of which email program someone is using at a given moment. Over time, such a collection of these notes, also capturing which clients prefer concise replies and which expect more elaborate explanations, lets a new customer-support team member quickly get up to speed on the communication style used with specific counterparts, instead of learning it by trial and error over their first few months on the job. It's also worth noting that such notes survive even a company's migration from one email provider to another, whereas correspondence history and the communication habits developed inside Foresty stay tied to a specific platform and a specific email account. That platform independence is exactly what makes these notes a more durable knowledge foundation than the inbox itself.

What SumizAI is

A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.

A vault is a directory holding base.md, a generated table of contents up to six levels deep, and a notes/ folder with one .md file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.

The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Side by side

Where they differ

• Foresty is a place to have the conversation. SumizAI is not a chatbot — the conversation is the input, not the product. What comes out of it is a .md file with a title, a place in base.md and a duplicate check against the notes already in the vault. If you only want to talk to a model, you do not need SumizAI.
• Foresty is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
• AlternativeTo's description of Foresty does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard .md files to a folder you picked, and an unpaid account can still export all of them.
• Foresty runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
